Ingredients You’ll Need

Before we start, set everything on the counter, once that sous vide bath is ready, things move quickly. Each ingredient plays a part in building the prawns’ juicy texture and the buttery, citrusy finish that makes this dish shine.

For the Prawns

• 1 lb (450 g) jumbo prawns, peeled and deveined, tails left on for presentation. Choose fresh if possible; frozen works if thawed properly.
• 1 tablespoon olive oil – helps the seasoning cling and adds richness to the bag.
• 1 small lime, thinly sliced – infuses gentle citrus aroma during cooking.
• 1 garlic clove, smashed – adds depth and a hint of savory flavor.
• Salt and freshly ground black pepper, to taste – keep it light; the butter will add more flavor later.

For the Chili Lime Butter

• 4 tablespoons unsalted butter, softened – the creamy base for that luscious glaze.
• 1 small red chili, finely chopped – brings mild heat; adjust to your spice comfort.
• Zest and juice of 1 lime – for bright, zippy flavor that cuts through the richness.
• 1 small garlic clove, minced – layers in aromatic depth.
• 1 tablespoon fresh cilantro, finely chopped – adds freshness and color.
• ½ teaspoon honey – balances acidity and spice.
• Pinch of sea salt – enhances all the other flavors beautifully.

Tip: If fresh chili isn’t available, use ¼ teaspoon chili flakes. And if you’re making this for a crowd, double the butter, it stores perfectly in the fridge for later.

Step-by-Step Instructions

Cooking prawns sous vide is easier than you might think, the machine does most of the work for you. Follow these steps, and you’ll end up with juicy, buttery prawns that taste like they came straight from a coastal bistro.

Step 1: Preheat Your Sous Vide Water Bath

Fill your sous vide container with water and set the temperature to 135°F (57°C).
This is the sweet spot for tender, juicy prawns, they’ll stay plump and silky, never tough or dry. While the water heats, prepare the prawns.

Step 2: Season and Seal the Prawns

Pat the prawns dry with paper towels, then season lightly with salt and black pepper.
Drizzle olive oil over them, toss gently to coat, and place them in a vacuum-seal bag with lime slices and the smashed garlic clove.
Seal the bag tightly, removing as much air as possible so the prawns cook evenly in the water bath.

Step 3: Cook Sous Vide

Once your water is at temperature, lower the sealed bag into the bath.
Cook for 30 minutes, during this time, the prawns will absorb the light citrus aroma from the lime and garlic while staying perfectly moist.

Step 4: Make the Chili Lime Butter

While the prawns cook, combine softened butter, minced garlic, chopped chili, lime zest and juice, cilantro, honey, and a pinch of sea salt in a small bowl.
Mix until smooth and creamy. Set aside at room temperature so it’s ready to melt beautifully later.
This is where the magic happens, that butter becomes your flavor bomb.

Step 5: Sear and Glaze the Prawns

When the prawns are done, remove them from the bag and pat dry again (moisture prevents browning).

Heat a skillet over medium-high heat, melt a spoonful of your chili lime butter, and quickly sear the prawns for about 30–45 seconds per side, just until they get a light golden edge.
Toss them in the remaining butter to coat evenly.

The sizzling butter releases that irresistible aroma, bright lime, rich butter, and just a whisper of chili. That’s your cue: dinner’s ready.

Pro Tips for Juicy Prawns

Cooking seafood sous vide might sound high-tech, but it’s all about precision and patience. These quick tips will help you get the most out of every bite.

• Pat Dry Before Searing: Moisture prevents browning, so make sure to dry the prawns thoroughly after removing them from the sous vide bag. You’ll get that lovely golden edge in seconds.
• Don’t Skip the Rest: After searing, let the prawns sit for a minute before serving. This allows the juices to redistribute, keeping the texture plump and tender.
• Mind the Temperature: 135°F (57°C) is ideal for prawns, they stay succulent and slightly firm. Going higher can toughen the meat.
• Use Real Butter, Not Margarine: Butter adds richness and helps carry the lime and chili flavor beautifully.
• Double the Butter, Save for Later: Make extra chili lime butter and freeze it in portions. It’s fantastic melted over grilled fish, rice, or veggies later in the week.
• Don’t Overcrowd the Pan: When searing, give each prawn space to brown evenly instead of steaming.

Fast fact: Prawns are naturally lean, yet rich in protein, around 20 grams per 3-ounce serving, making them one of the healthiest indulgences you can cook.
