How to Defrost Salmon Quickly

How to Defrost Salmon Quickly?

Coming home after a long, hectic day, I’m often seeking a nutritious and tasty meal that also doesn’t require too much time and effort to prepare. Salmon is one of my favorite go-to choices to meet this need. Rich in healthy omega-3 fatty acids and protein, salmon offers a quick, satisfying meal. However, I usually have individually vacuum-sealed frozen salmon filets on hand rather than fresh. This means I need to defrost salmon properly before cooking.

Depending on the situation, you may or may not need to defrost salmon before cooking. Thawing is more important for cooking larger cuts or filets. Knowing the quickest and safest methods allows you to enjoy delicious salmon dishes on a tight schedule. In this article, I’ll share the best practices for how to defrost salmon quickly while maintaining quality and food safety.

Do You Need to Thaw Your Frozen Salmon?

For smaller individually vacuum-sealed filets, you can often cook straight from frozen. However, thawing becomes important for larger cuts of salmon to ensure proper, even cooking and food safety.

Thawing Necessity for Larger Pieces of Fish

Cooking larger, thicker cuts of frozen salmon comes with some risks. Without thawing, the inside can remain undercooked while the outside becomes overdone. Frozen sections may also cook at different rates, leading to uneven texture. For food safety, large pieces of fish need to reach 140°F internally to destroy bacteria and parasites. So thawing helps ensure the salmon cooks evenly throughout.

Cooking Small Vacuum-Sealed Salmon Filets from Frozen

Individually vacuum-sealed salmon filets around 1 inch thick can usually be cooked straight from the freezer. The flash-freezing process locks in moisture and quality. Smaller filets cook through more quickly and evenly when pan-fried or baked. With proper technique, you can cook frozen filets to perfection without thawing first.

Adjustments Needed for Cooking Methods When Cooking from Frozen

However, you may need to adjust temperature and cooking times to account for frozen salmon. Lower heat slightly and increase cooking time to allow the inside to cook through without burning the outside. Also, methods like grilling should be avoided from frozen to prevent drying out the delicate flesh.

How to Thaw Vacuum-Sealed Fish the Right Way

While cooking frozen salmon offers convenience, thawing first is necessary with larger cuts. It also allows better moisture retention and texture. But improper thawing introduces some risks. Follow these best practices when thawing vacuum-sealed fish.

Precautions When Thawing Vacuum-Sealed Fish

Vacuum-sealing extends frozen seafood’s shelf life dramatically by protecting against oxidation and freezer burn. However, it also creates an oxygen-free environment ideal for bacterial growth. So once thawed, lingering bacteria can multiply quickly if left at unsafe temperatures for too long.

Removing Elements That Promote Bacterial Growth

To prevent potential bacterial growth when thawing vacuum-sealed salmon, first remove any accumulated liquid inside the package. Liquids act as a bacterial breeding ground. Puncture the package to release liquids before thawing.

Puncturing the Vacuum Package Before Thawing

Another vital step is puncturing the vacuum-sealed package before thawing. This allows proper air circulation to prevent a humid environment inviting bacteria. Simply poke a few small holes in the packaging with a fork before starting to thaw.

The Best Way to Thaw Salmon (and Any Frozen Fish)

For ideal results when you have time, thawing salmon slowly overnight in the refrigerator is best. Here’s how to safely defrost salmon using the fridge method.

Thawing Method: Overnight in the Fridge

Overnight fridge thawing brings the temperature of the frozen salmon up gradually under safe chilled conditions. This avoids potential bacterial growth from warmer temperatures. Thawed slowly at colder fridge temperatures, the fish retains moisture and freshness better.

Steps for Overnight Thawing in the Fridge

To thaw salmon in the fridge overnight:

  1. Puncture any vacuum-sealed packaging and drain liquid before placing the frozen salmon in a container or on a plate.
  2. Put the salmon on a bottom shelf of the fridge, away from any raw meats to prevent cross-contamination.
  3. Allow around 8-10 hours for a 1-inch filet, and 24 hours for a large 3-4 lb salmon steak or fillet.

Precautions and Considerations for Fridge Thawing

A couple of cautions when using the overnight fridge method: First, expect some odor from the thawing fish. Second, even when thawed at optimal temperatures, don’t leave the salmon in the fridge longer than 1-2 days before cooking.

Thawing Salmon in the Sink: The Second-Best Way

When you’re in a time crunch, thawing in the fridge may not be fast enough. Here are quicker ways to defrost salmon when needed sooner.

Thawing Salmon in the Sink in a Shorter Time Frame

For faster thawing, you can submerge the vacuum-sealed salmon in a bowl or pot of cold tap water. The water conducts heat faster for quicker thawing time. Change the water every 30 minutes so it stays cold.

Steps for Thawing Salmon in the Sink

To defrost salmon in the sink:

  1. Poke holes in the vacuum bag, drain liquid, and place sealed salmon filets in a bowl of cold tap water.
  2. Replace water every 30 minutes with more cold running water to keep it chilled below 40°F.
  3. Depending on thickness, the salmon should thaw in 1-3 hours.

Microwave Thawing as an Alternative for Quick Thawing

The microwave offers the fastest way to thaw salmon when you need it in under an hour. However, microwave thawing can start cooking the salmon, so precision is vital.

How to Thaw Salmon in the Microwave

Microwave thawing is quick but can impact texture and quality if not careful. Here are some microwave salmon thawing tips:

Microwaves thaw unevenly, leading to partly cooked sections if not monitored. They also heat up any bacteria present instead of destroying them. So extra care is required compared to other methods.

Steps for Microwave Thawing

To thaw salmon in the microwave:

  1. Determine the weight of the frozen salmon and microwave wattage to calculate defrosting time (around 6-8 minutes per pound at 50% power).
  2. Microwave in bursts, checking every minute. Turn over halfway through. Stop early if sections start feeling warm.

Tips for Cautious Microwave Thawing

Go slowly and in short increments. Salmon should still feel cold and firm when done for the best texture and safety. Defrosting times vary, so monitor closely and don’t overdo it.


Whether you have all night or just an hour, properly defrosting salmon ensures delicious, safe results. Overnight fridge thawing is ideal for food safety and quality. For quicker results, thaw in cold water in the sink, changing it out to keep it chilled. Or use the microwave carefully if really pressed for time.

The key is finding the right method to fit your schedule and meal plans to enjoy fresh-tasting, healthy salmon dishes any night of the week. Follow these tips to master how to defrost salmon quickly while retaining quality and avoiding bacteria. Thawed properly, salmon cooks up moist, tender and full of flavor.
