How to Thaw Seafood Properly Without Ruining Its Texture

Great seafood can lose its delicate texture before it even reaches the pan. The problem is often not the product or the recipe—it is the way the seafood was thawed.

Thawing seafood too quickly, exposing it directly to warm water, or leaving it on the kitchen counter can create uneven temperatures, excess moisture, dry edges, and a softer or rubbery texture. The best approach is gradual, controlled thawing that keeps the seafood cold and protects its natural juices.

Whether you are preparing Norwegian salmon, shrimp, fish fillet, or products from the Sea Fruits collection, this guide will help you thaw seafood safely while maintaining better flavour and texture.

Why the Thawing Method Affects Seafood Texture

Seafood contains a high percentage of water. During freezing, some of that water forms ice crystals inside and around the muscle fibres. When the seafood thaws, those crystals melt and moisture begins to leave the product.

A controlled thaw gives that moisture less opportunity to escape rapidly. Sudden temperature changes, direct water exposure, and partial cooking can increase moisture loss and leave seafood softer, drier, or less able to brown properly.

• Slow, cold thawing helps seafood retain a more natural texture.
• Hot or warm water can warm the exterior while the centre remains frozen.
• Direct water contact may make seafood waterlogged and difficult to sear.
• Microwave thawing can begin cooking thin edges before thicker areas have thawed.
• Room-temperature thawing exposes the surface to unsafe temperatures while the centre may still be frozen.

The Best Method: Thaw Seafood in the Refrigerator

Refrigerator thawing is generally the best method for both food safety and texture. The seafood remains at a consistently cold temperature while it thaws gradually and evenly. 

Step-by-Step Refrigerator Method

1. Remove the seafood from the freezer the night before cooking.
2. Check the pack instructions and remove any external cardboard packaging if necessary.
3. Place the sealed pack on a plate, tray, or shallow container to catch any liquid.
4. Keep it on the lowest refrigerator shelf, away from ready-to-eat food.
5. Allow it to thaw gradually until the centre is no longer firm or icy.
6. Open the pack, drain any liquid, and pat the seafood dry before seasoning.

Small portions and thin fish fillets may thaw overnight, while thick salmon cuts, large bags of shrimp, or a whole side of salmon may require more time.

Why This Method Protects Texture

• The temperature changes gradually.
• The seafood thaws more evenly from the outside to the centre.
• Less surface moisture builds up suddenly.
• The seafood remains cold throughout the process.
• You have better control over when it is ready to cook.

The Faster Method: Thaw Seafood in Cold Water

When you do not have time for an overnight refrigerator thaw, cold water is the safest practical shortcut. Keep the seafood inside a sealed, leak-proof bag and fully submerge it in cold water.

Step-by-Step Cold-Water Method

1. Keep the seafood in its original sealed pack or place it in a leak-proof food-safe bag.
2. Fill a clean bowl with cold tap water.
3. Submerge the sealed pack completely.
4. Change the water approximately every 30 minutes so it remains cold.
5. Check the seafood regularly and remove it once fully thawed.
6. Cook it immediately after thawing.

Cold-water thawing is faster than refrigerator thawing, but food thawed this way should be cooked immediately. Direct contact with water should be avoided because excess moisture can interfere with browning and may weaken the final texture. 

Can You Thaw Seafood in the Microwave?

A microwave can be used in an emergency, but it is not the best method when texture matters. Microwave energy heats food unevenly, so the edges of a fish fillet or shrimp may begin to cook while the centre remains frozen.

This can create:

• Dry or firm edges
• Rubbery shrimp
• Uneven cooking later
• More moisture loss
• Partially cooked spots

When microwave thawing is unavoidable, use the defrost setting in short intervals, rotate the seafood frequently, and cook it immediately afterwards.

Seafood Thawing Methods You Should Avoid

Leaving Seafood on the Counter

Do not leave frozen seafood at room temperature until it feels soft. The exterior can warm significantly while the centre remains frozen, creating both food-safety concerns and uneven texture.

Using Warm or Hot Water

Warm water may feel faster, but it can start cooking the outside of shrimp or fish. This often produces dry edges, soft surfaces, and uneven cooking.

Running Seafood Directly Under Water

Thawing unpackaged seafood directly under the tap can add unnecessary moisture. A wet surface makes it harder to achieve a proper sear, crisp coating, or caramelised finish.

Leaving Seafood in Melted Ice Water

Seafood should not sit unprotected in a pool of melted ice. Keep it sealed, cold, and separated from standing water.

Refreezing After Improper Thawing

Seafood thawed in cold water or in a microwave should be cooked before it is frozen again. Seafood thawed safely in the refrigerator may generally be refrozen, but repeated freezing and thawing can reduce quality and increase moisture loss. 

How to Thaw Salmon Properly

Salmon contains natural fat and has a delicate, flaky structure, so gentle refrigerator thawing is especially useful. This applies to salmon portions, chunks, cubes, steaks, and whole sides.

Best Method for Salmon Portions

• Place the sealed portion on a plate in the refrigerator.
• Allow it to thaw gradually overnight.
• Drain the pack after thawing.
• Pat the salmon dry before adding oil or seasoning.
• Cook only when the centre has thawed evenly.

Best Method for Salmon Chunks and Cubes

Smaller cuts thaw more quickly than full portions. Spread the sealed pack flat in the refrigerator so the pieces thaw evenly rather than remaining frozen together in a thick block.

Best Method for a Whole Side of Salmon

A whole side requires more planning. Transfer it to the refrigerator at least one day before cooking and place it on a large tray that can catch any liquid. Avoid bending or forcing the fillet apart while it is still frozen.

How to Thaw Frozen Shrimp Without Making It Rubbery

Shrimp cooks very quickly, which means poor thawing can affect it more noticeably. Hot water and microwave heat can begin tightening the proteins before cooking starts, creating a bouncy or rubbery texture.

Overnight Method

1. Place the sealed bag of frozen shrimp on a tray in the refrigerator.
2. Allow it to thaw gradually.
3. Drain any released liquid.
4. Pat the shrimp thoroughly dry.
5. Cook within the recommended period shown on the product packaging.

Quick Cold-Water Method

1. Place the sealed bag in a bowl of cold water.
2. Change the water regularly.
3. Separate the shrimp gently as they begin to thaw.
4. Remove them as soon as they become flexible.
5. Pat dry and cook immediately.

Drying shrimp properly after thawing helps it sear instead of steaming in the pan.

How to Thaw Fish Fillet

Boneless fish fillets are generally thin and can thaw faster than whole fish. However, they are also delicate and may tear if handled before fully thawed.

• Keep the fillet flat while thawing.
• Do not pull apart fillets that are still frozen together.
• Pat the surface dry before coating or seasoning.
• Use a fish spatula when moving thin, delicate fillets.
• Cook shortly after thawing for the best result.

How to Thaw Calamari, Mussels, and Seafood Mix

Products from the Sea Fruits collection may contain pieces of different sizes. Shrimp, calamari, mussels, and seafood mix can therefore thaw at slightly different speeds.

For Calamari Rings

Thaw in the refrigerator, drain thoroughly, and pat dry. Extra surface water can dilute marinades and prevent proper browning.

For Mussels

Follow the product packaging carefully, particularly for cooked, raw, shell-on, or half-shell mussels. Keep them cold and use them promptly after thawing.

For Seafood Mix

Thaw the complete pack gradually in the refrigerator. Drain it in a colander after thawing and dry the larger pieces before stir-frying, adding them to pasta, or cooking them with rice.

Should You Rinse Seafood After Thawing?

Rinsing is not always necessary. In most cases, draining the liquid and patting the seafood dry is enough.

If you choose to rinse away loose ice crystals, use cold water briefly and dry the seafood immediately afterwards. Avoid soaking fish or shrimp directly in water.

Why Patting Seafood Dry Is Important

Drying seafood after thawing may seem like a small step, but it makes a major difference during cooking.

• Dry salmon develops better colour in the pan.
• Dry fish fillets hold seasoning and coating more effectively.
• Dry shrimp sear instead of releasing excess water.
• Dry calamari browns more easily and is less likely to steam.
• Less surface water means marinades remain more concentrated.

How to Know When Seafood Is Fully Thawed

Seafood is generally ready to cook when:

• It bends without a hard frozen centre.
• The pieces separate without force.
• No large ice crystals remain inside the pack.
• The surface feels cold but not frozen solid.
• The thickness feels consistent from edge to centre.

Do not force apart seafood that is still frozen. This can tear fish fillets, damage shrimp, or break delicate seafood pieces.

Can You Cook Seafood from Frozen?

Some seafood can be cooked from frozen when the product instructions or recipe specifically allow it. However, thawing first usually gives you more control over seasoning, browning, cooking time, and doneness.

Cooking from frozen may be suitable for:

• Some breaded or ready-to-cook seafood
• Thin fish fillets prepared using a suitable recipe
• Seafood being added directly to soups or sauces
• Products whose pack instructions specifically recommend frozen cooking

Always follow the instructions printed on the individual product packaging.

Common Signs That Seafood Was Thawed Poorly

• Large amounts of liquid inside the pack
• A soft or mushy surface
• Dry, pale, or partially cooked edges
• Shrimp that becomes rubbery immediately after cooking
• Fish that releases too much water in the pan
• Coating that slides off instead of becoming crisp
• Uneven cooking between the centre and the edges

Quick Seafood Thawing Guide

Final Thawing Checklist

• Plan ahead and use the refrigerator whenever possible.
• Keep seafood inside a sealed pack during cold-water thawing.
• Never use hot water.
• Do not leave seafood on the kitchen counter.
• Cook seafood immediately after microwave or cold-water thawing.
• Drain released liquid.
• Pat the seafood dry before seasoning or cooking.
• Follow the storage and preparation instructions on the product pack.

Conclusion: Better Thawing Means Better Seafood

The best seafood meals begin before the cooking starts. Gradual refrigerator thawing protects texture, cold-water thawing provides a safe faster option, and proper drying helps seafood brown and cook more evenly.

Avoid warm water, countertop thawing, and unnecessary soaking. Give salmon, shrimp, fish fillet, calamari, mussels, and seafood mix enough time to thaw gently, and you will get better texture, better colour, and more consistent results from every recipe.
