Does Freezing Salmon Ruin It? Everything You Need To Know
Salmon is one of the most popular and nutritious fish available. Rich in protein, omega-3 fatty acids and various vitamins and minerals, salmon provides an array of health benefits. Its tender texture and versatile flavor also make it a favorite among home cooks.
With salmon’s rising popularity, many people opt to buy it in bulk or stock up when it’s on sale. Freezing is a convenient way to store salmon long-term while preserving freshness But a common question is does freezing salmon ruin it?
The short answer is freezing can damage salmon’s texture and flavor if not done properly However, following best practices for freezing salmon can help maintain quality for months In this comprehensive guide, we’ll cover everything you need to know about freezing salmon, including proper methods, what can go wrong, thawing, storage times and more.
How Freezing Affects Salmon
Freezing puts salmon in a state of suspended animation by slowing down spoilage. At freezing temperatures, the growth of bacteria and microorganisms is halted. Enzyme activity in the fish that causes natural breakdown of tissue is also slowed. This prevents rotting and allows fish to be preserved for extended periods.
However, freezing doesn’t come without consequences. Some key structural changes happen to salmon during freezing:
-
Ice crystals form, rupturing cell membranes and changing texture
-
Fats oxidize, leading to rancidity and off-flavors
-
Proteins denature, making the flesh mushy
-
Moisture migrates, resulting in freezer burn
While freezing stops salmon from spoiling quickly, it can degrade quality if not done with care. Let’s look at proper techniques for freezing salmon.
Best Practices For Freezing Salmon
Follow these tips to freeze salmon correctly and prevent damage:
-
Freeze as soon as possible after catching or buying. Fresher fish freezes better.
-
Bleed, gut and clean salmon before freezing. Bacteria and enzymes in viscera speed spoilage.
-
Cut into portions and seal in airtight bags or containers. Remove air to prevent freezer burn.
-
Glaze salmon with ice water to guard against oxidation and dehydration.
-
Freeze at 0°F or below. Colder temperature minimizes quality loss. Use the coldest area of the freezer.
-
Avoid refreezing previously frozen salmon. Texture quickly becomes mushy.
-
Label frozen salmon with type, date, weight. Track shelf life.
-
Use frozen salmon within 3 months for best flavor, texture and nutrition.
What Can Go Wrong When Freezing Salmon
Even when using proper methods, there are factors that can still diminish frozen salmon quality:
Freezer Burn
One of the biggest risks is freezer burn. This occurs when salmon is exposed to air in the freezer, causing moisture loss and oxidation. Signs are white/gray, dry, flaky patches. It creates an unpleasant texture and rancid taste.
Temperature Fluctuations
If frozen salmon experiences temperature changes, such as the freezer door opening often, icing and thawing can damage tissue. Keep your freezer consistently at 0°F or below.
Long-Term Storage
Over an extended period, enzymatic and oxidative changes happen, making the flesh progressively mushier and cause off-flavors. Use frozen salmon within 3 months for best quality.
Improper Packaging
If not sealed in airtight, moisture-proof packaging, frozen salmon can dry out. Use high-quality freezer bags or containers when freezing. Vacuum seal if possible.
Repeated Freezing/Thawing
Each freeze/thaw cycle breaks down cell structure further. Don’t refreeze previously frozen salmon more than once.
Thawing Frozen Salmon
Thawing is also critical for maintaining quality. Improper thawing leads to additional cellular damage. Here are some guidelines:
-
Thaw in the refrigerator overnight. Keeps bacteria growth in check.
-
Submerge in cold water, changing water every 30 mins. Thaws gently.
-
Microwave only if cooking immediately after. Can make texture mushy.
-
Never thaw at room temperature. Risks bacteria proliferation.
-
Cook from frozen in soups, stews or chowders. Liquid helps thaw evenly.
-
Avoid refreezing thawed salmon. Texture quickly deteriorates.
Frozen Salmon Shelf Life
How long can you freeze salmon before it goes bad? Properly frozen and stored at 0°F, salmon can safely last:
-
Raw salmon: 3-6 months before decline in texture and flavor
-
Smoked salmon: 1 month maximum for best quality
-
Canned salmon: Can be frozen for up to 2-3 months after opening
-
Fresh caught salmon: Up to 12 months when frozen quickly and correctly
The fattier the salmon, the shorter the freezer life. Fattier varieties like king and sockeye don’t freeze as well long-term compared to leaner fish like Atlantic salmon.
How To Know If Frozen Salmon Has Spoiled
Check frozen salmon for these signs of spoilage before cooking:
-
Strong, offensive fishy/ammonia smell
-
Discoloration and darkening of flesh
-
Dehydrated or frosty patches (freezer burn)
-
Slimy, mushy texture
-
Dull, faded appearance
If you notice any of these, it’s best to throw away the salmon. Do not taste or eat spoiled salmon due to food safety risks.
Frequently Asked Questions
Can you freeze smoked salmon?
Smoked salmon can be frozen but does not keep as long as raw salmon. Smoky flavor fades over time. For best quality, eat within 1 month of freezing smoked salmon.
Can you refreeze thawed salmon?
It’s unsafe to refreeze thawed salmon more than once, as texture quickly becomes mushy and unappealing. Only refreeze if kept chilled below 40°F since thawing.
Can you freeze salmon for sushi/sashimi?
Freezing raw salmon for sushi or sashimi is not recommended. Freezing may not kill parasites that can cause foodborne illness when eaten raw.
Should you freeze salmon skin-on or skin-off?
Skin helps protect salmon when freezing. Leaving skin on helps maintain moisture and minimizes freezer burn. Skin also seals in flavor.
Can you freeze cooked salmon?
Cooked salmon can be frozen but does not preserve as well as raw. Eat within 1-2 months for best flavor and texture. Let it cool before freezing.
The Bottom Line
When frozen and stored properly, salmon can retain its fresh texture and flavor for months. Quickly freeze the freshest salmon at 0°F in airtight packaging. Thaw in the refrigerator or cold water only. With some care, you can enjoy delicious frozen salmon just like it was freshly caught.
How Long Can You Keep Salmon Frozen?
The duration for which salmon can be freezed varies depending on the type of salmon.
To maximize the shelf life of an opened package of smoked salmon, tightly wrap it in a heavy-duty aluminum or plastic wrap.
Properly stored, an opened packaged lasts for about one month in the freezer but remains safe beyond that time.
Constantly refrigerated canned salmon is safe for up to 3-4 days. You can extend the shelf life of canned salmon by freezing it.
Constantly frozen canned salmon, at 0°F, remains safe for consumption for up to 3 months.
When frozen, raw salmon will maintain its best quality for about 2-3 months. Though you can freeze it for up to six months, its quality starts degrading after three months.
To freeze raw salmon, first rinse it, pat it dry, and wrap in an air-tight container. Label it with the date of freezing, and use it before six months.
How To Thaw Frozen Salmon
When it comes to defrosting and thawing frozen salmon, you have a few options. Cooking frozen salmon may spoil its flavor and texture. So, be careful and allocate enough time to defrost the fish properly so that its flavor and nutrients remain intact. Remember, thawing is different than reheating. We’ve discussed how to properly reheat salmon on this post.
Make sure you keep the fish away from a dangerous temperature range (41-135°F) where salmon can grow bacteria.
Let your frozen salmon thaw naturally in the refrigerator for about 12 hours or more. Plan your meal in advance and transfer the frozen salmon to the refrigerator.
If the salmon weighs more than one pound, take it out of the freezer 24 hours before cooking time. Remove it from the packaging and wrap in a plastic wrap that is big enough to hold the entire piece. Keep it away from sweet food; otherwise, it may absorb the fishy smell.
If you are in a hurry and have only one hour to cook your dish, you can defrost the salmon in cold tap water.
Remove the salmon packaging, package it again in a dry zip-lock bag and seal it closed. Place the bag in a large bowl so that the fish defrosts evenly.
Next, move the bowl in the sink and fill it with cold tap water. Do not thaw out fish in hot water because it may create the risk of bacterial growth.
Replace water in the bowl every 10-15 minutes until the fish completely defrosts. Cook the salmon immediately; otherwise, the fish may go bad if left uncooked for too long.
Though microwave thawing is the quickest way to defrost salmon and prepare it for cooking, this method is our least recommended option. We’re not fans of this method because microwave heating may pass harmful cause uneven thawing of the salmon and there is more of a risk of bacterial growth.
To thaw salmon in the microwave, remove the salmon from its packaging. Then place it on a paper towel in the microwave. Position the fish so that the thinnest parts rest in the middle of the container. Cover the fish with another paper towel.
Set the timer five minutes for every one pound of salmon. Let the microwave run for two and a half minutes and then flip the salmon to the other side. Keep thawing for one minute.
Once your salmon is thawed properly, you can broil, grill, fry, or cook it!

FAQ
Why should you not freeze salmon?
It has to be commercially/industrially flash frozen for eating raw. Slow freezing in a home freezer, no matter how cold, will result in a gross texture in your fish. The ice crystals that form tear the flesh. Flash freezing happens so fast crystals don’t have a chance to destroy the meat.
Does freezing salmon make it mushy?
The fish can get mushy, since the muscles and fibers break up after time in the freezer.” As cell membranes break down, conductive fluids build up in the flesh. The lack of intact membranes (which make fresh fish firm) and additional moisture create the mushier texture.
Does salmon taste different after freezing?
When thawed correctly, frozen fish can retain its original flavor and texture, making it just as enjoyable as fresh fish. Don’t let the myth that frozen fish loses its flavour and texture turn you off from all the delicious variety of seafood out there.
Can salmon get bad in the freezer?
To freeze raw salmon, keep the fish in its original packaging or transfer it to a resealable freezer-safe bag. USDA guidelines suggest that raw salmon can last up to three months from the date of purchase when stowed below 0 degrees F in the freezer before its quality deteriorates.Oct 30, 2024
