How To Refreeze Tilapia

Tilapia is versatile seafood and once you take it out from the freezer and thaw, you need to be careful with the handling so that the tilapia refreeze well.

To refreeze the tilapia perfectly, follow the steps listed below for you

  • For raw tilapia that thaw on the way back home, clean it thoroughly before placing it in the freezer. It will help the fish keep all its rich flavors while refreezing.
  • Cover it in a heavy-duty freezer bag to ensure it remains intact. It will prevent the formation of ice crystals.
  • If you have a large amount of tilapia, lay each fish on a tray with wax paper and flash-freeze it for two to three hours.
  • When frozen, take it out of the freezer and wrap each separately in good-quality aluminum foil.
  • Now, transfer it to a freezer bag to provide maximum coverage to the fish and protect it from freezer burns.
  • For cooked tilapia, cool it down before shifting it to the freezer. If you freeze it while still warm, it can spoil very quickly.
  • Once it reaches the right temperature, you can vacuum seal the fish. Remove all the excess air out from the bag until it deflates completely. You can use a straw for this purpose if you don’t have a vacuum sealer device.
  • Lastly, mention the refreezing date on the bag/container and let the tilapia refreeze for a few months.

How Long Is It Safe To Refreeze Tilapia?

Whether cooked or uncooked, tilapia can refreeze for a decent amount of time if you follow all the safety instructions. When you thaw it in the refrigerator, the tilapia can remain refrozen for up to six months without getting rancid.

It is recommended to vacuum seal the fish before refreezing. Vacuum-sealed fish generally lasts longer compared to other safety packaging. The exposure to air is minimal, and the fish remain in a good state without losing their nutritional value. After some time, the fish might suffer degradation in taste and texture due to the extreme freezer environment. So, it is better to utilize it soon and not keep it refrozen and unchecked.

Also, if you leave tilapia raw or cooked at room temperature for too long, drop the idea of refreezing. Even if you place it in the freezer afterward, it cannot refreeze for a long time and might turn inedible. Thus, it is better to discard the fish as consuming it can cause food poisoning.

Can You Refreeze Tilapia More Than Once?

The short answer is NO!

As tilapia is protein-based, it is vulnerable to deteriorating faster. Freezing it again after thawing might be okay if you do it once, but avoid overdoing it. Inside the freezer, food gets exposed to low temperatures, causing the formation of ice crystals. When you refreeze it one time, the fish already suffers a quality loss and is no more suitable for another round of freezing.

If you refreeze it again, the tilapia might turn mushy, discolored due to freezer burns, and taste awful. Eating it will not be a pleasant experience, and you will have to discard it. So, to save time and effort, you can freeze your tilapia in meal-size portions. It will allow you to thaw only the required amount instead of defrosting the whole together.


Refreezing fish requires extra effort and can remain in the freeze for many months. It is of utmost importance to thaw it in the fridge and not by other methods if you want to refreeze the leftovers. Defrosting on the kitchen counter or hot water may not support the freezing process.

Ensure to store tilapia in proper safety containers or bags for effective freezing and prevent the tender meat from perishing early. If the packaging is not sturdy enough, the fish can lose its texture and flavor and turn dry. You can opt for vacuum sealing for better and long-lasting results.
