Cooking fish can be tricky—even a few seconds too long on the heat can turn a delicate fillet into a dry, rubbery disappointment. But what if there was a way to guarantee tender, moist, and flavour-packed seafood every time? Enter sous vide, the ultimate technique for perfectly cooked fish.

If you’ve ever been intimidated by cooking seafood, this method will change the way you approach it. Whether you’re working with salmon, barramundi, prawns, or scallops, sous vide ensures consistent results with minimal effort. Let’s dive into how it works and why it’s the best-kept secret for cooking seafood to perfection.

What is Sous Vide Cooking?

Sous vide (pronounced “soo veed”) is a French cooking technique that means “under vacuum.” It involves sealing food in a vacuum-sealed bag and cooking it in a precisely controlled water bath at a low temperature. Unlike traditional methods that rely on direct heat, sous vide cooks food evenly from edge to center, eliminating the risk of overcooking.

For seafood, which is delicate and easy to overcook, sous vide is a game-changer. It locks in moisture, enhances natural flavours, and provides a buttery, melt-in-your-mouth texture.

Why Sous Vide is Perfect for Seafood

1. Precise Temperature Control

Unlike pan-frying or grilling, where heat fluctuates and food can cook unevenly, sous vide keeps fish at the perfect temperature for its entire cooking time. For example, salmon cooked at 50°C (122°F) comes out rich, tender, and flaky every single time.

2. No More Overcooking

Since sous vide cooks at a set temperature, the fish never exceeds that heat level. This means no more dry, tough seafood—just perfectly moist fillets with a restaurant-quality finish.

3. Enhanced Flavour & Moisture

Sealing fish in a bag with herbs, butter, citrus, or seasonings allows it to marinate while it cooks, resulting in deep, infused flavours. The vacuum seal also prevents moisture from escaping, keeping seafood succulent.

4. Consistent, Foolproof Results

Whether you’re cooking one fillet or five, sous vide guarantees even cooking across all portions. No more guesswork or constantly checking for doneness.

How to Sous Vide Seafood: A Step-by-Step Guide

1. Choose Your Seafood & Seasonings

Sous vide works well with most seafood, but some varieties truly shine with this technique. Here are some top picks and their best flavour pairings:

• Salmon – Naturally rich and buttery; pairs well with dill, garlic, and citrus.
• Barramundi – A firm white fish that absorbs flavours beautifully; try with lemon, thyme, or miso.
• Snapper – Mild and slightly sweet; great with fresh herbs, butter, and a touch of spice.
• Prawns – Retain a juicy, snappy texture when sous vide; perfect with chili, garlic, and lime.
• Scallops – Become incredibly tender with this method; enhance with brown butter, capers, or saffron.

For the best results, season simply with salt, pepper, garlic, butter, and citrus or experiment with marinades featuring soy sauce, miso, coconut milk, or chili.

2. Seal in a Bag

Place the seafood in a vacuum-sealed bag, ensuring an even layer for consistent cooking. If you don’t have a vacuum sealer, use the water displacement method: place the seafood in a zip-lock bag and slowly lower it into a water-filled bowl to push out air before sealing.

3. Set the Temperature & Cook

Different seafood types require specific temperatures for optimal texture:

• Salmon: 50°C (122°F) – Soft, flaky, and moist.
• White Fish (Barramundi, Snapper): 54°C (130°F) – Firm yet tender.
• Prawns: 60°C (140°F) – Juicy and slightly firm.
• Scallops: 52°C (126°F) – Silky, melt-in-your-mouth texture.

Cooking time varies based on thickness, but a general rule of thumb is 30 to 45 minutes. Since sous vide prevents overcooking, a few extra minutes won’t ruin your seafood.

4. Sear for the Perfect Finish

Sous vide seafood is fully cooked when it comes out of the water bath, but it benefits from a quick sear for texture and enhanced flavour. Heat a pan over high heat with a touch of butter or oil and sear fish for 30 seconds per side—just enough to create a golden crust while keeping the inside tender.

For prawns and scallops, searing is essential to lock in flavour and give them that perfect caramelisation.

Best Seafood & Sauce Pairings

Pairing the right sauce with your sous vide seafood takes the dish to the next level:

• Salmon + Dill Butter Sauce – A creamy, herby complement.
• Barramundi + Lemon Garlic Sauce – Bright and refreshing.
• Snapper + Mango Salsa – Sweet and slightly tangy.
• Prawns + Chili Lime Butter – A spicy, zesty kick.
• Scallops + Brown Butter & Capers – Rich and nutty.
