Refreezing Cooked Fish

  1. Select a fish that is higher in fat such as farmed salmon. Farmed salmon has a higher fat content and will hold up better to refreezing. Make sure the fish is brought to room temperature or cooler before sealing. This will prevent you from burning your fingers or building steam inside the vacuum-sealed bag.

  2. Cut the vacuum bag to the right size of your piece of cooked fish. Leave a minimum of two to four inches around the piece of cooked fish to seal the it properly.

  3. Load the vacuum sealer bag into the vacuum, and seal the fish. Seal the fish until all the air is eliminated in the bag.

  4. Mark the bag with the date on which you sealed the fish. You will have to eat or use this fish within three months of sealing.

  5. Place the fish into the freezer immediately.
