(I like to lay everything out on a sheet tray with lemon wedges and call it dinner party–ready in seconds.)

If you’re a fan of low-fuss seafood dishes, you’ll also love this one-pot shrimp pasta with white wine or my lemon garlic cod packets, both big on flavor, short on cleanup.

Fast Fact: Pressure cookers were first introduced in the U.S. in the 1930s. The Instant Pot just made them cool again.

Ingredients You’ll Need

This Instant Pot seafood boil keeps the classics you know and love but gives you plenty of room to riff based on what’s fresh, what’s frozen, or what’s on sale. Here’s your grocery list:

The Seafood

• Shrimp – Large or jumbo, shell-on for the most flavor.
• Crab legs – Snow crab or king crab both work well.
• Mussels or clams – Optional, but they soak up the broth beautifully.
• Lobster tails – A luxe upgrade if you’re feeling fancy (or it’s date night).

The Add-Ins

• Baby potatoes – Red or gold, halved.
• Corn on the cob – Fresh or frozen, cut into halves or thirds.
• Smoked sausage – Andouille or kielbasa, sliced thick.

Flavor Base (Liquid + Seasoning)

• Seafood stock or chicken broth – Adds depth to the pressure steam.
• Garlic – Fresh cloves, smashed.
• Old Bay seasoning – Or your favorite Cajun blend.
• Lemon – Juiced and sliced.
• Bay leaves – Optional, but aromatic.
• Butter – For finishing, melted and drizzled over everything.

You can mix and match the seafood to suit your taste, or your freezer. For instance, if you’re out of crab legs, doubling up on shrimp still delivers that satisfying, briny bite.

Want a spicier kick? Try stirring in a spoonful of spicy seafood butter right before serving. It’s magic.

Did You Know? Old Bay was created in 1939 by a German immigrant in Maryland and originally aimed to season crabs on Chesapeake Bay.

Step-by-Step: How to Make Seafood Boil in an Instant Pot

Making a seafood boil in the Instant Pot takes just a few thoughtful layers and a little attention to timing. This Instant Pot seafood boil method guarantees tender veggies, juicy sausage, and seafood that’s just-cooked, not rubbery.

1. Prep Your Ingredients

• Cut potatoes in half.
• Slice sausage into thick coins.
• Halve corn cobs.
• Rinse seafood, especially if using mussels or clams (discard any that don’t close when tapped).

2. Build Your Flavor Base

• Pour 1.5 cups of seafood stock or broth into the Instant Pot.
• Add smashed garlic, lemon juice, Old Bay, and bay leaves.

3. Layer Ingredients in This Order

1. Potatoes (they need the most time)
2. Sausage
3. Corn
4. Shellfish and shrimp last (on top of trivet or foil sling if delicate)

Don’t stir! Let gravity and pressure do their thing.

4. Pressure Cook

• Seal the Instant Pot.
• Set to Manual/High Pressure for:
  • 5 minutes for fresh seafood
  • 2–3 minutes if using pre-cooked or thawed frozen items
• Once finished, quick release the pressure.

5. Finish and Serve

Carefully open the lid, remove everything with tongs, and lay it out on a large platter or parchment-lined tray. This Instant Pot seafood boil is perfect drizzled with melted butter, a sprinkle of extra seasoning, and lemon wedges.

Want a little extra flair? Spoon over some garlic butter sauce or serve with crusty bread to mop up the juices.

Tips for Perfect Texture & Bold Flavor

The beauty of an Instant Pot seafood boil is how much flavor you can build in such a short time, but a few smart moves will take it from good to unforgettable.

Don’t Overcook the Seafood

Shrimp, mussels, and crab all cook quickly, just a few extra minutes can mean rubbery textures. To stay safe:

• Use the quick release method as soon as pressure cooking is done.
• Layer seafood on top so it’s exposed to the least amount of direct heat.
• If you’re worried about overcooking, try steaming shrimp separately using the “Steam” function for 1 minute, then add it after.

Balance the Spice

Old Bay or Cajun blends can vary wildly in saltiness. Taste your broth before adding seafood. You can always add more seasoning later, especially when tossing with melted butter or a spiced oil drizzle like this Creole shrimp boil butter.

Use Citrus + Garlic for Depth

Don’t skip the lemon or garlic. Together, they cut through the richness and bring freshness to every bite. I always toss in a few lemon slices with the broth and squeeze more over the tray before serving.

Bonus Boosters

• Smoked paprika adds warmth and color.
• A knob of butter stirred into the broth pre-cook gives richness to the steam.
• Splash in a bit of beer or white wine for a more layered aroma.

Here’s a quote I just created while writing this article:

“The secret’s in the steam. If it smells amazing when you lift the lid, you’re doing it right.”

Serving Ideas & What to Pair It With

One of the best parts of an Instant Pot seafood boil is the way it turns any meal into an experience. No plating finesse required, just flavor, fun, and maybe a few napkins.

How to Serve It

• Tray-style: Line a sheet pan or newspaper-covered table with parchment. Pile your Instant Pot seafood boil high and scatter lemon wedges and parsley.
• Individual bowls: Great for portion control and easy cleanup.
• Foil packets: Portion out boil ingredients into foil, drizzle with butter, and broil for 2 minutes for crispy edges.

Serve hot with plenty of melted butter and paper towels on the side.

Dipping Sauces & Sides

• Classic garlic butter, Cajun mayo, or lemony remoulade work wonders.
• Add crusty sourdough or buttermilk cornbread for sopping up every drop.
• Cool things down with grilled lemon asparagus or a citrusy slaw.

Drink Pairings

• Pilsner or lager plays nicely with spice.
• Wine? Try Sauvignon Blanc or a dry rosé.
• Or go zero-proof with sparkling lemonade or cucumber-lime water.

Did You Know? In coastal boil traditions, what you drink with your seafood is almost as important as how it’s seasoned!

Spicy Creole Instant Pot Shrimp Boil

The sizzle of spice, the kick of cayenne, and the smoky depth of Creole seasoning, that’s what sets this shrimp boil apart. If the classic version above is all about rich, garlicky comfort, this one is its fiery cousin, built for those who crave heat and crave it now.

In just under 30 minutes, your Instant Pot transforms shrimp, corn, sausage, and potatoes into a Southern-style feast with a bold Louisiana twist. Every bite brings layers of flavor: smoky andouille sausage, tender potatoes, sweet corn, and shrimp bathed in a broth that’s bold with Creole seasoning, hot sauce, and cayenne.

Warning: napkins are non-negotiable!

Ingredients You’ll Need

• 2 pounds large shrimp (shell-on or peeled, deveined; tails optional)
• 1 pound baby red potatoes (halved or quartered)
• 4 ears corn on the cob (cut into thirds)
• 12 ounces smoked andouille sausage (sliced into 1-inch pieces)
• 1 stick (½ cup) unsalted butter (divided)
• 5 garlic cloves (minced)
• 1 lemon (halved, juice squeezed in, wedges for serving)
• 3 cups low-sodium chicken broth or seafood stock
• 2 tablespoons Creole seasoning
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• 1 teaspoon cayenne pepper
• 2–3 teaspoons Louisiana-style hot sauce (Crystal or Tabasco)
• 2 bay leaves (optional)
• Fresh parsley (chopped, for garnish)

Pro tip: If you want an even bolder broth, stir an extra splash of hot sauce into the butter before tossing everything together at the end.

Before You Start: Prep Tips

• Shrimp prep – If using shell-on shrimp, give them a quick rinse and devein them. Keeping tails on adds presentation value, but if you’re serving kids or want less mess, go tail-off.
• Potato cutting – Baby red potatoes cook best when halved or quartered. Uniform sizes mean they’ll be fork-tender at the same time.
• Corn cutting – Slice each ear into thirds. This makes them easier to serve and lets the kernels soak up more of the spicy broth.
• Managing spice – Creole seasoning blends vary. Taste yours first, some are salty, others are fiery. Balance with your hot sauce and cayenne accordingly.
• Instant Pot setup – Check that the sealing ring is secure and the vent knob is on “Sealing.” Keep a towel or long spoon handy for safe quick-release.

Did you know? Louisiana hot sauce is aged in barrels, similar to how Tabasco ferments its peppers, this gives it a tangy depth that stands up beautifully in seafood boils.

Step-by-Step Instructions

Step 1: Bloom the spices and garlic Set your Instant Pot to the Sauté function. Melt half of the butter (¼ cup), then add the minced garlic. Stir for about 1 minute until fragrant. Sprinkle in the Creole seasoning and cayenne to toast the spices lightly, which deepens their flavor.

Step 2: Build the broth and cook potatoes Pour in the chicken broth (or seafood stock) and squeeze in the juice of one lemon. Stir in the salt, black pepper, bay leaves, and a few dashes of hot sauce. Add the potatoes to the pot. Seal the lid, set to High Pressure, and cook for 5 minutes.

Step 3: Add corn and sausage When the timer finishes, do a quick release of pressure. Open the lid carefully, then add the corn and sausage slices. Seal the lid again and cook on High Pressure for 2 minutes.

Step 4: Add the shrimp Quick release again. Open the lid and immediately add the shrimp on top. Reseal the Instant Pot and cook on High Pressure for 1 minute. Quick release once more, this ensures the shrimp stay tender and juicy. Discard the bay leaves.

Step 5: Finish with hot sauce butter and serve Switch back to Sauté mode. Stir in the remaining butter along with more hot sauce (to taste) until melted and everything is coated in spicy, buttery goodness. Transfer the boil to a large platter or parchment-lined table. Garnish with parsley and serve with lemon wedges on the side.

Here’s a tip: If you want an extra fiery finish, drizzle a little hot sauce directly over the shrimp just before serving.

Notes about this recipe:

• Adjust spice level to your taste by reducing or increasing cayenne and hot sauce.
• For pescatarian version, skip sausage or substitute with extra veggies like mushrooms.

---

Spicy Creole Variations

• Milder Version – If you love the idea but not the fire, cut the cayenne in half and skip the extra hot sauce at the end. The Creole seasoning alone still brings bold flavor.
• Seafood Swap – Try mixing in crab legs, crawfish, or mussels along with the shrimp for a full-blown seafood boil experience.
• Vegetarian/Pescatarian – Skip the sausage and add mushrooms, zucchini, or extra corn for a lighter version that’s still plenty satisfying.
• Extra Smoky – Use double-smoked andouille or even a touch of smoked paprika for a deeper Southern profile.
• Make It a Feast – Double the recipe and serve it alongside other party favorites like hush puppies or fried oysters for a full-on coastal spread.

Did you know? Creole seasoning blends often include paprika, thyme, oregano, garlic powder, onion powder, and cayenne, so every brand has its own signature twist.

Easy Instant Pot Garlic Butter Shrimp Boil

There’s something irresistible about the way garlic and butter mingle with shrimp in a bubbling pot. This Instant Pot Garlic Butter Shrimp Boil takes that magic and turns it into a cozy, family-friendly dinner.

Instead of leaning on heavy Cajun spices, the broth here is rich with butter, garlic, lemon, and just a touch of herbs, perfect for kids and anyone who prefers lighter flavors. It’s a complete meal in one pot with tender shrimp, sweet corn, and potatoes soaking up all that savory goodness.

If you’ve tried our Easy Boiled Shrimp Recipe, you’ll notice the difference right away. That version highlights the clean, natural taste of shrimp with a simple water-and-lemon boil. This one is heartier, more flavorful, and meant to be ladled right onto the table for everyone to dig into.

Ingredients You’ll Need

• 2 pounds large shrimp (shell-on or peeled, deveined; tail-on for presentation if you like)
• 1 pound baby red potatoes (halved or quartered so they cook evenly)
• 4 ears corn on the cob (cut into thirds for easy serving)
• 12 ounces smoked sausage (optional, sliced into 1-inch pieces; you can skip for a lighter, pescatarian version)
• 1 stick (½ cup) unsalted butter (divided; half for cooking, half for tossing at the end)
• 6 garlic cloves (minced, for that buttery-garlic base)
• 1 lemon (halved, with juice squeezed into the pot; wedges for serving)
• 3 cups low-sodium chicken broth or water (broth adds more depth of flavor)
• 1 teaspoon kosher salt (plus more to taste)
• ½ teaspoon black pepper (freshly cracked is best)
• 2 teaspoons Old Bay or mild seafood seasoning (optional; use sparingly for a kid-friendly touch)
• 2 bay leaves (optional, for a subtle background aroma)
• Fresh parsley (chopped, for garnish)

Step-by-Step Instructions

Step 1: Sauté garlic and butter

Turn on the Instant Pot to the Sauté function. Melt half of the butter (¼ cup) and add the minced garlic. Stir for about 1 minute until fragrant, being careful not to let it burn. This will create the base of your buttery broth.

Step 2: Build the broth and add potatoes

Pour in the chicken broth (or water), squeeze in the juice of one lemon, and season with salt, pepper, bay leaves, and a light sprinkle of seafood seasoning if using. Stir well, then add the potatoes. Cover the Instant Pot, seal the lid, and set to High Pressure for 5 minutes.

Step 3: Add corn and sausage

Once the timer is done, do a quick release of pressure. Carefully open the lid, then add the corn pieces and sausage slices. Reseal and cook on High Pressure for 2 minutes.

Step 4: Add shrimp and finish with butter

Quick release again. Open the lid and immediately add the shrimp on top. Reseal the Instant Pot and cook on High Pressure for 1 minute. Quick release right away so the shrimp don’t overcook. Discard bay leaves, then stir in the remaining butter until melted and everything is coated in that rich garlic sauce.

Step 5: Serve family-style

Transfer everything to a large platter or spread out on parchment paper for a fun, hands-on dinner. Garnish with chopped parsley and extra lemon wedges. Serve hot, with plenty of napkins on hand!

Here’s a tip: If you want even more buttery goodness, drizzle a little extra melted butter over the shrimp right before serving.

Easy Instant Pot Shrimp and Crab Boil

There’s something undeniably festive about a seafood boil, platters piled high with shrimp, crab, potatoes, and corn, all tossed together in buttery, seasoned goodness. And thanks to the Instant Pot, you don’t need a big outdoor setup to enjoy this coastal tradition at home.

We’ve already shared a few Instant Pot favorites, like the bold and spicy Creole Shrimp Boil, the comforting Garlic Butter Shrimp Boil, and the all-in-one Seafood Boil. But this version is all about shrimp and crab, cooked in a lemony Old Bay broth and finished with a fresh herb butter that makes every bite feel special.

It’s a little lighter than the Creole, a little zestier than the garlic butter, and just right for when you want shrimp and crab to be the stars of the show.

Ingredients You’ll Need

• 1 ½ pounds large shrimp – shell-on for the best flavor (peeled and deveined optional).
• 1 ½ pounds crab legs – snow crab or king crab, pre-cooked and thawed.
• 1 pound baby red potatoes – halved or quartered, depending on size.
• 4 ears corn on the cob – cut into thirds for easier serving.
• 12 ounces smoked sausage – sliced into 1-inch rounds (andouille or kielbasa both work).
• 1 cup seafood stock – or substitute with chicken broth.
• 1 cup light lager beer – classic for boils, or replace with more stock if preferred.
• 1 stick (½ cup) unsalted butter – divided, half for cooking and half for finishing.
• 4 garlic cloves – minced for building the broth.
• 1 lemon – juiced, plus extra wedges for serving.
• 2 tablespoons Old Bay seasoning – the backbone of boil flavor.
• 1 teaspoon kosher salt – adjust to taste.
• ½ teaspoon black pepper – freshly ground.
• 2 bay leaves – for added depth.
• 2 tablespoons fresh parsley – chopped.
• 1 tablespoon fresh dill – chopped (optional but brightens the flavor).
• 1 teaspoon fresh thyme leaves – or a pinch of dried thyme.

Step-by-Step Instructions

Step 1: Build the Broth

Set your Instant Pot to Sauté mode. Melt half the butter (¼ cup) and add the minced garlic. Cook for 1 minute until fragrant. Stir in the Old Bay seasoning, salt, pepper, and bay leaves to bloom the spices. Pour in the seafood stock and beer, then squeeze in the lemon juice. Stir well.

Step 2: Cook the Potatoes

Add the halved baby potatoes to the pot. Seal the Instant Pot lid, set to High Pressure, and cook for 5 minutes. Once done, perform a quick release.

Step 3: Add Corn and Sausage

Open the lid and add the corn pieces and sliced smoked sausage. Reseal the lid and cook on High Pressure for 2 minutes. Quick release again when the timer ends.

Step 4: Add Crab Legs and Shrimp

Place the crab legs and shrimp on top of the cooked ingredients. Seal the lid once more and cook on High Pressure for 2 minutes. Quick release immediately to prevent overcooking the shrimp.

Step 5: Finish with Herb Butter

Switch back to Sauté mode. Stir in the remaining ¼ cup butter, along with chopped parsley, dill, and thyme. Toss everything gently until coated in the herb butter.

Step 6: Serve and Enjoy

Transfer the shrimp, crab, sausage, corn, and potatoes to a large platter or parchment-covered table. Garnish with extra parsley and serve with lemon wedges and dipping sauces on the side.

And here’s a little secret: tossing in a second squeeze of lemon just before serving lifts everything up with a sunny, briny zing.

Individual Instant Pot Shrimp Boil Packets

I still remember the first time I cooked a shrimp boil for just two people. I stood there with a massive Instant Pot, spread out enough ingredients to feed eight, and thought, “There has to be a better way.” Then it hit me: why not wrap everything into individual foil packets?

Now, dinner for two feels intimate, elegant, and completely stress-free. These Instant Pot shrimp boil packets deliver all the coastal charm of a traditional seafood boil, but in perfectly portioned servings that feel like you’re dining at a restaurant, not your kitchen.

The beauty of this recipe is that it transforms a fun, messy-table affair into something surprisingly refined. Each packet steams open at the table, releasing that heavenly garlic-butter aroma, and suddenly you’re celebrating seafood in a whole new way.

No massive platters, no fighting over corn, just fresh shrimp, tender vegetables, and buttery broth all waiting inside a little foil package made just for you.

Ingredients You’ll Need

For 2 to 4 individual packets (adjust amounts based on serving size):

• 1.5 pounds large shrimp with shells removed and veins cleaned, tails intact (or remove tails entirely if you prefer easier eating)
• 12 ounces small red potatoes, cut in half or into quarters for even cooking
• 2 to 3 ears of fresh corn, sliced into thirds (or use frozen corn kernels if preferred)
• 8 ounces andouille sausage (smoked), cut into thin rounds; adds smoky depth
• 4 tablespoons unsalted butter, divided (2 tablespoons for broth, 2 tablespoons melted for finishing)
• 3 garlic cloves, minced; use fresh garlic for the best aromatic punch
• 1 lemon, halved with juice squeezed out; reserve wedges for serving
• 1.5 cups reduced-sodium chicken broth or seafood stock
• 1.5 teaspoons Old Bay seasoning (adjust to your spice preference)
• 1/2 teaspoon sea salt, plus extra to taste
• 1/4 teaspoon freshly ground black pepper
• 1/2 teaspoon cayenne pepper (optional; adjust based on heat preference)
• 2 bay leaves, divided between packets
• Chopped fresh parsley for garnish
• Fresh thyme (optional), for an herbaceous note
• Heavy-duty aluminum foil for wrapping packets

Step-by-Step Instructions

Step 1: Prepare Your Broth Base

In a small bowl, whisk together 1.5 cups chicken broth, juice from half a lemon, minced garlic, 2 tablespoons butter, Old Bay seasoning, salt, pepper, and cayenne (if using). Taste and adjust seasoning. This broth mixture is what flavors every packet, so don’t skip this step.

Step 2: Assemble the First Packet

Tear off a large sheet of heavy-duty foil (about 18 inches). Place it shiny-side up on your counter. In the center, create a bed with about 1/4 of your potatoes. Layer 1/4 of the corn pieces on top, then add about 6 to 8 shrimp (depending on packet size). Sprinkle a few sausage slices if using. Add a bay leaf. Pour about 1/3 cup of your broth mixture into the center of the packet.

Step 3: Seal the Packet

Fold the foil in half over the filling, then fold the open edges down tightly to seal. You want it airtight so steam stays inside. The packet should be roughly rectangular and puffy when done, about 6 to 8 inches long. Don’t squeeze it too tightly, as the ingredients need room for steam to circulate.

Step 4: Repeat for Remaining Packets

Make as many packets as needed, using the same layering and portion method. Each packet should hold similar amounts so they finish cooking uniformly.

Step 5: Add Water to Your Instant Pot

Pour 1 cup of water into the bottom of your Instant Pot. Place the trivet (metal rack) inside. This is the foundation for steam generation, so don’t skip this step.

Step 6: Arrange Packets on the Trivet

Place your foil packets directly on the trivet, stacking them if needed. If you have many packets, stack them gently, foil-side up so steam can circulate around them.

Step 7: Cook Under High Pressure

Close the Instant Pot lid, make sure the pressure valve is set to “”Sealing,”” and set to High Pressure for 8 minutes. Your Instant Pot will require about 3 to 5 minutes to reach high pressure before the timer starts, so be patient.

Step 8: Natural Release

Once the timer sounds, allow a natural pressure release for 5 minutes. This gives the shrimp time to finish cooking gently without overcooking. After 5 minutes, execute a quick release by carefully adjusting the vent to “”Venting.”” Be cautious of the steam that escapes.

Step 9: Carefully Remove and Open Packets

Use tongs to remove each foil packet from the Instant Pot and place on a plate or small cutting board. Let sit for 1 minute so the steam settles, then carefully open the foil (it’s hot, so use caution). The shrimp should be opaque and tender, vegetables fork-tender, and broth rich and garlicky.

Step 10: Finish and Serve

Transfer the contents of each packet to a shallow bowl if desired, or serve the packet open on a plate. Drizzle with an extra teaspoon of melted butter, fresh parsley, and fresh thyme. Squeeze a fresh lemon wedge over the top.

Pro tip: If you’re meal prepping, build a batch of packets on Sunday, freeze them, and cook them throughout the week for quick dinners. The combination of seafood, vegetables, and broth makes for a balanced, protein-packed meal that reheats beautifully.

Classic Cajun Instant Pot Shrimp Boil

There’s something about the cooler months that makes you crave comfort food with character. Autumn and winter are the perfect seasons for a Classic Cajun Instant Pot Shrimp Boil. As the weather turns crisp, hearty, flavorful dishes become less about refreshment and more about gathering around the table with people you love, warming your hands on a steaming bowl, and diving into something bold and satisfying.

This Classic Cajun version is part of our growing series of Instant Pot shrimp boil recipes, each bringing its own personality to the table.

Ingredients You’ll Need

Every ingredient here plays a role in building that authentic Cajun experience, so don’t skip or substitute without reason.

For 6 to 8 people:

• 3 pounds large shrimp, peeled and deveined, tails on (or tail-off for easier eating)
• 2 pounds baby red potatoes, halved or quartered depending on size
• 6 ears fresh corn on the cob, cut into thirds for easier serving
• 1 pound smoked andouille sausage, sliced into thin rounds; this is the star of the broth flavor
• 1 stick (1/2 cup) unsalted butter, divided; half for the trinity, half for finishing
• 2 medium yellow onions, diced into small pieces (Cajun trinity, part 1)
• 4 celery stalks, diced into small pieces (Cajun trinity, part 2)
• 2 large bell peppers (red or yellow work beautifully), diced into small pieces (Cajun trinity, part 3)
• 4 garlic cloves, minced; use fresh for best results
• 5 cups low-sodium chicken broth or seafood stock
• 2 lemons, halved and juiced; reserve wedges for serving
• 2 tablespoons smoked paprika, adds depth and color
• 1.5 tablespoons cayenne pepper, adjust based on heat preference
• 2 teaspoons dried thyme, or 1 tablespoon fresh thyme leaves
• 2 teaspoons garlic powder (on top of fresh garlic, for layered flavor)
• 1 teaspoon onion powder, complements the fresh onions
• 1.5 teaspoons kosher salt, plus more to taste
• 1/2 teaspoon black pepper, freshly cracked
• 3 bay leaves, essential for Cajun depth
• 1 teaspoon hot sauce (Louisiana-style, like Crystal or Tabasco), optional but recommended
• Fresh parsley, chopped, for garnish
• Fresh green onions, thinly sliced, for garnish

Step-by-Step Instructions

Step 1: Bloom the Cajun Trinity

Set your Instant Pot to Sauté mode. Melt 1/4 cup of butter (half your butter) and add the diced onions, celery, and bell peppers. Stir frequently and cook for about 4-5 minutes until the vegetables soften and become fragrant. They should be slightly caramelized at the edges, which deepens the flavor. This is the foundation, so don’t rush this step.

Step 2: Add Garlic and Toast the Spices

Add the minced garlic and cook for another minute, stirring constantly, until fragrant. Be careful not to let it burn. Now add the smoked paprika, cayenne pepper, thyme, garlic powder, onion powder, salt, pepper, and bay leaves.

Stir everything together and let the spices toast in the butter for about 30 seconds. You’ll smell the spices bloom as they release their oils. This is exactly what you want.

Step 3: Add the Broth and Lemon

Pour in your chicken broth and squeeze in the juice from both lemons. Stir well, making sure to scrape up any browned bits from the bottom of the pot (this is called deglazing, and it’s where a lot of flavor lives). Taste the broth and adjust seasonings now, before you add anything else. This is your moment to dial in the heat and salt levels.

Step 4: Add the Sausage and Potatoes

Add the sliced andouille sausage and the halved potatoes to the broth. Give everything a good stir. Close the Instant Pot lid and set the vent to “”Sealing.”” Select High Pressure and set the timer for 5 minutes. The Instant Pot will take 3-5 minutes to come to pressure before the timer starts, so be patient.

Step 5: Quick Release and Add Corn

When the timer beeps, carefully perform a quick release by moving the vent to “”Venting.”” Be cautious of the steam that escapes. Open the lid and add all the corn pieces. Stir gently, reseal the lid, and set to High Pressure for 2 minutes.

Step 6: Quick Release Again and Add Shrimp

When the timer beeps, quick release again. Open the lid and add all the shrimp on top of the vegetables and sausage. Don’t stir them in yet, just let them rest on top. Reseal the Instant Pot and cook on High Pressure for exactly 1 minute. This quick cook keeps the shrimp tender and juicy, not rubbery.

Step 7: Final Quick Release and Rest

When the timer beeps, perform one final quick release. Open the lid carefully. The shrimp should be bright pink and opaque. If any are still translucent, close the lid and cook for another 30 seconds, then check again. Once done, remove the bay leaves and discard them.

Step 8: Finish with Butter and Final Seasoning

Switch the Instant Pot back to Sauté mode. Stir in the remaining 1/4 cup of butter and the teaspoon of hot sauce (if using) until everything is coated in that rich, glossy broth. Taste one more time and adjust salt or spice as needed. This is your last chance to perfect the flavor before serving.

Step 9: Transfer to Serving Platter

Turn off the Instant Pot. Using a slotted spoon or tongs, carefully transfer the shrimp, sausage, potatoes, and corn to a large platter or parchment-lined table. Pour the broth into a separate bowl or ladle it directly over the seafood. This is where the magic happens, this is where your guests see what you’ve created.

Step 10: Garnish and Serve

Top everything with fresh chopped parsley and sliced green onions. Set out lemon wedges so guests can squeeze them over their portions. Serve hot, with extra napkins nearby because this is a hands-on, joyful meal meant to be enjoyed with abandon.
