Can You Freeze Salmon?

Yes — both raw and cooked salmon freeze well. The keys are to wrap it tightly, freeze it while it's fresh (within a day or two of buying), and use it within about 3 months. As an oily fish, salmon keeps a little less long than lean white fish, because its natural fats slowly turn over time — but freezing is still by far the best way to save a fillet you won't cook in the next day or two.

Fresh salmon has one of the shortest fridge lives of anything you buy, so freezing the portion you won't use today is a real money-saver. Fango lets you log salmon and set a reminder to cook or freeze it before its tight window closes.

How to Freeze Salmon — Step by Step

Wrapping well is what protects salmon from freezer burn and keeps that fresh texture. The FDA advises wrapping fish tightly and keeping fresh fish in the fridge only 1–2 days before cooking or freezing.

1. 1
   Freeze it fresh. Freeze salmon while it's at its best — within a day or two of buying, and before its use-by date. Freezing pauses it as it is; it won't improve a fillet that's already turning.
2. 2
   Pat dry and wrap tightly. Blot the fillets dry, then wrap each tightly in cling film or freezer paper. Excess surface moisture forms ice crystals that harm the texture.
3. 3
   Bag in portions. Seal the wrapped fillets in a freezer bag, pressing out the air. Freezing individual portions means you thaw exactly what you need.
4. 4
   Label and date. Mark each portion and use within about 3 months. See the full guide to freezing food for more.

How to Thaw and Cook Frozen Salmon

The safest thaw is slow and cold. Move salmon to the fridge to defrost overnight — never on the worktop, where the outside warms into the danger zone while the middle is still frozen. For a faster thaw, seal it in a bag and sit it in cold water. Once thawed, cook within a day and don't refreeze it raw.

• Thaw in the fridge overnight, or in cold water for a quicker result.
• Cook from frozen if you forget — bake or pan-cook with a few extra minutes.
• Check it's cooked to at least 63°C, or until the flesh flakes easily and is opaque.
• Use thawed salmon within a day, and never leave it out at room temperature.

If your salmon is already past its best before you freeze it, freezing won't fix that — see how to tell if salmon is bad first, and how long salmon lasts in the fridge for fresh storage.

A Note on "Previously Frozen" Salmon

Much of the salmon sold at fish counters and in chilled packs was frozen at sea and thawed for sale. If the label says "previously frozen" or "defrosted," don't refreeze it raw — cook it first, and you can then freeze the cooked dish once. When in doubt, treat shop salmon as fresh, cook it within a day or two, and only freeze raw fillets you're confident haven't already been through a freeze-thaw cycle. The same care applies to other seafood like prawns.

Frequently Asked Questions

Can you freeze salmon?

Yes. Raw and cooked salmon both freeze well. Wrap it tightly and freeze raw salmon while it's fresh, ideally within a day or two of buying it. Use within about 3 months for best quality — as an oily fish, salmon keeps a little less long than lean white fish.

How do you freeze raw salmon?

Pat the fillets dry, wrap each tightly in cling film or freezer paper, then seal in a freezer bag with the air pressed out. Freeze in individual portions so you can thaw one at a time. Label and date, and freeze it while it's still fresh.

How long does salmon last in the freezer?

Raw salmon keeps its best quality for about 3 months in the freezer; cooked salmon a little less. It stays safe for longer while frozen, but as an oily fish the texture and flavour decline faster than lean fish, so use it within a few months.

How do you thaw frozen salmon?

Thaw salmon in the fridge, ideally overnight, never on the worktop. For a faster thaw, seal it in a bag and immerse in cold water. Once thawed, cook it within a day and don't refreeze raw salmon.

Can you cook salmon from frozen?

Yes. Salmon can be baked or pan-cooked from frozen — add a few extra minutes and check it's cooked through to at least 63°C, or until it flakes easily. Cooking from frozen is handy when you forget to thaw it.

Can you refreeze salmon?

Don't refreeze raw salmon that has thawed. You can freeze salmon you've cooked from previously frozen raw fish — for example, thaw a fillet, cook it, then freeze the cooked dish once. Much shop salmon was frozen at sea, so check it hasn't been "previously frozen" before refreezing raw.

The habit that saves the most fish: log salmon in Fango the day you buy it and freeze any you won't cook within a day or two. A wrapped fillet in the freezer is a quick dinner waiting to happen.
