Salmon is one of the most popular and nutritious fish available. Many people choose to buy salmon frozen for convenience and to save money by purchasing in bulk. However, there is often confusion around how long thawed frozen salmon will last in the refrigerator before spoiling. This article will provide details on how to safely thaw frozen salmon and how long it can be kept refrigerated before use.
How to Thaw Frozen Salmon
It is important to thaw frozen salmon properly to help prevent bacterial growth. Here are some recommended safe methods for thawing:
In the Refrigerator
The safest way to thaw frozen salmon is by placing it in the refrigerator. Allow 24 hours of thaw time for every 1 pound of frozen salmon. Place the frozen salmon in a container or on a plate to catch any drips as it thaws. Thawing in the refrigerator helps prevent bacterial growth by keeping the salmon at a safe temperature below 40°F.
In Cold Water
You can also thaw frozen salmon by submerging it in cold water. Place the frozen salmon in a leak-proof plastic bag. Submerge the bag in cold tap water, changing the water every 30 minutes until the salmon is thawed. The salmon should thaw after about 2-3 hours in cold water. This method also keeps the fish cold while thawing.
In the Microwave
For a quick thaw, you can use the microwave. Place the frozen salmon in a microwave-safe container and microwave at 30% power. Check and flip the salmon every minute or so until thawed. Take care not to cook the salmon and be sure all areas are fully thawed. The microwave can start cooking the outside while the inside is still frozen.
How Long Does Thawed Salmon Last in the Fridge?
Once thawed, fresh salmon will generally stay good for 1 to 2 days when stored properly in the refrigerator. Follow these storage tips to maximize the shelf life after thawing:
- Keep thawed salmon stored in the coldest part of the refrigerator (below 40°F).
- Place thawed salmon on a plate or in a container to prevent leaks and contamination.
- Cover the salmon tightly with plastic wrap or foil.
- Use thawed salmon within 1 to 2 days for best quality.
Freezing actually preserves the quality of salmon very well. So if previously frozen salmon has been thawed safely in the refrigerator, it should retain much of its freshness for that 1-2 day period when kept cold.
How to Tell If Thawed Salmon Is Bad
Thawed salmon that has gone bad will show signs of spoilage. Discard any thawed salmon that has the following characteristics:
- Slimy texture and foul odor
- Discoloration and grayish tint
- Dry, dull flesh
- Mold growth
When salmon has spoiled, it may also seep liquid and have an ammonia-like or off smell. Any odd colors, textures, or smells mean the thawed salmon should be thrown out.
Can You Refreeze Thawed Salmon?
Previously frozen salmon that has been thawed in the refrigerator can be refrozen safely if done properly. Follow these tips for refreezing thawed salmon:
- Only refreeze salmon that has been thawed in the refrigerator, not at room temperature.
- Use the thawed salmon within 1-2 days before refreezing for best quality.
- Make sure the salmon has been kept at 40°F or less during thawing.
- Wrap salmon tightly in freezer wrap or foil and freeze immediately.
- Consume refrozen salmon within 3-4 months for best flavor.
Thawed salmon that shows any signs of spoilage should be discarded instead of refrozen.
Can You Cook Thawed Salmon Right Away?
Yes, thawed frozen salmon can be cooked immediately after thawing in the refrigerator. The fish will retain much of its freshness when properly thawed at 40°F or below. Follow these tips when cooking thawed salmon:
- Pat the salmon dry before cooking – moisture can cause steaming instead of searing.
- Brush lightly with oil or rub with spices/herbs to add flavor.
- Cook thawed salmon within 1-2 days for best results.
- Cook to an internal temperature of at least 145°F.
Thawed salmon works very well for almost any cooking method including baking, broiling, grilling, poaching, pan frying, and sautéing.
How Long is Cooked Salmon Good For?
Cooked salmon that has been refrigerated should be consumed within 3 to 4 days. Here are some storage guidelines for cooked salmon:
- Refrigerate cooked salmon in a shallow covered container.
- Use cooked salmon within 3 days for freshest taste and quality.
- Cooked salmon keeps for 3-4 days if stored properly.
- Do not freeze previously cooked salmon.
- Discard cooked salmon that is moldy, has an off smell or very dry texture.
Properly cooked salmon that is immediately refrigerated after cooking and stored correctly can last 3-4 days at most before spoiling.
How Long Does Frozen Salmon Last?
Here is a table summarizing how long frozen salmon will last in the freezer:
| Freezer Temperature | Fresh Frozen Salmon | Previously Thawed Salmon |
|---|---|---|
| 0°F or below | 9-12 months | 3-6 months |
| 10°F | 6-9 months | 2-4 months |
| 15°F | 4-6 months | 1-3 months |
For best quality and longest freezer life, store frozen salmon below 0°F if possible. Handle frozen salmon carefully to avoid freezer burn which can shorten shelf life. Use an air-tight freezer container or bag to prevent absorption of odors from other foods.
Conclusion
Thawed frozen salmon will keep in the refrigerator for 1-2 days. Refreezing thawed salmon can extend the shelf life for another 3-4 months if done properly. Cooked salmon lasts for 3-4 days refrigerated. And fresh frozen salmon has a freezer life of 9-12 months when stored continuously at 0°F. Following safe thawing, storage, freezing, cooking, and refrigeration guidelines will help maximize the shelf life and freshness of your salmon.
