Why You’ll Love This Instant Pot Seafood Boil

This isn’t just a shortcut recipe, it’s a flavor-packed experience made weeknight-friendly. Using the Instant Pot means you get the deeply seasoned taste of a long-simmered seafood boil without waiting hours or firing up an outdoor burner.

It’s a cozy, communal kind of meal that comes together in under 30 minutes and brings that beachside boil energy right to your kitchen table.

The real beauty? Consistency. Pressure cooking ensures even doneness across everything, from fork-tender potatoes to perfectly cooked shrimp that practically pop when you bite into them.

Plus, it infuses each ingredient with smoky sausage, garlic, lemon, and seasoning in one go. Less hovering over the stove, more time sipping something cold while the pot does the work.

Whether you’re cooking for a casual crowd or just feeding yourself with leftovers in mind, this Instant Pot seafood boil scales up beautifully. And because it all cooks in one pot, cleanup is delightfully minimal.

(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!
