How Long Will Frozen Salmon Be Good In The Freezer?
After knowing how long does salmon last in the fridge, you should know the time storing frozen salmon in the freezer. The storage duration of frozen salmon is typically 9-12 months. While it is safe to keep salmon in the freezer for an extended period, it is important to note that the quality may decline after the 12-month mark.
How Long Can Cooked Salmon Stay In The Fridge?

Can I Refreeze Previously Frozen Salmon?
It is safe to refreeze previously frozen salmon as long as it is still fresh and packaged appropriately. If you originally planned to cook the salmon but changed your mind, simply ensure that it is properly repackaged and return it to the freezer.

Can You Refreeze Thawed Salmon?
Refreezing thawed salmon is safe and in accordance with the USDA’s guidance. As long as the fish has been consistently kept at a refrigerator-like temperature and hasn’t spoiled, it can be refrozen without any concerns.
How To Tell If Salmon Is Bad?
Here are some ways to determine if salmon is bad:
- Expiration date: Check the salmon’s label for the expiration date. If it has passed the date, it should be discarded.
- Smell: Fresh salmon should have a neutral or mild smell. If it smells fishy, sour, or ammonia-like, it indicates spoilage.
- Appearance: Fresh salmon fillets should be bright pink or orange without any discoloration, darkening, or drying around the edges. Dull or gray coloring, dark spots, or filmy white residue are signs of spoilage. Whole fish should have clear, shiny eyes and red gills. Dull or faded eyes or gills indicate that the fish is not fresh.
- Texture: Fresh salmon has a firm texture, and the flesh should spring back when pressed. If the texture is mushy or slimy, it is a sign that the salmon is bad.
Note: According to the FDA website, “fresh fish and fish fillets sold as ‘Previously Frozen’ may not have all the characteristics of fresh fish (e.g., bright eyes, firm flesh, red gills, flesh, or bloodlines), however, they should still smell fresh and mild, not fishy, sour, or rancid.”
How To Reheat Salmon?

To reheat salmon, follow these steps:
- Place the fish on a rimmed baking sheet.
- Warm it in a 275°F oven for approximately 15 minutes.
- Check the internal temperature, ensuring it reaches 125°F to 130°F.
- Remember to go low and slow when reheating your leftover salmon fillet to prevent it from drying out. Additionally, add moisture back by splashing a little water.
Easy Salmon Recipe
For an easy salmon recipe, begin by marinating the fish fillets with olive oil, garlic powder, dried thyme, black pepper, and salt. Bake in a 425-degree Fahrenheit oven until cooked through, approximately 12 to 15 minutes. An alternative to olive oil is melted butter for marination. Serve with fresh salads like Western-style Caesar salad or Asian-style seafood salad. In East Asian cuisine, this fish protein is commonly paired with rice, warm soup, and pickled vegetables such as radish.

Otherwise 3 days is the limit.
Will freezing it preserve the freshness (taste wise)? Or will the fish still be about as fresh on Friday if I leave it in the fridge? It would be about 2.5 days at that point.
If you are cooking it then you ought to be fine to leave it out. If in fact you will be eating it raw then freeze it.
If you freeze it in an airtight baggy to prevent freezer burn the taste will be fine.
I’ll be roasting it so I’ll just leave it. Thanks! 🙂
Out of curiosity – can you eat regular salmon you buy at the grocery store raw (once frozen)? How do you know if something is sushi grade?
