Can I Cook Frozen Tilapia?
Do You Defrost Tilapia Before Cooking?
If you’re wondering ‘can you cook frozen fish without thawing?’, you’ll be glad to hear that it is safe to cook tilapia and a few other kinds of fish from frozen.
However, the cook time will be roughly 50% longer and you will have to be diligent about cooking the middle for long enough. Cooking from frozen works best for oven-baking – you can do this using other cooking methods too, but you’re honestly better off thawing first.

What To Know Before Thawing Frozen Fish
How Long Does Frozen Tilapia Take To Thaw?
This is highly dependent on the method you plan to use for thawing your tilapia. The longest (fridge-thawing) generally takes about twelve hours, whereas the shortest method (thawing in water) will take around half an hour.
Are There Any More Methods For Defrosting Tilapia?
Unfortunately, these are the only two guaranteed safe methods for defrosting frozen fish.
Other methods – like hot water defrosting – may spoil the texture of the fish. Even worse, something like microwave-defrosting can cause your fish to heat up and cook unevenly, making the food potentially unsafe for consumption.
Worst Ways To Defrost Fish
Never defrost fish by leaving it at room temperature. This includes leaving it on the counter for an hour to thaw. This will make your fish unsafe for consumption and will render it unusable.
The same goes for hot-water defrosting and especially for microwave thawing.
Cooking tilapia from frozen is different when as, when done right, as the fish is heated up evenly at a low temperature and is immediately put into the cooking process as soon as it is thawed.

How Do You Defrost Tilapia Quickly
To defrost your tilapia quickly, use the cold water method.
- Begin by placing your fish in a plastic resealable bag if not already wrapped – this will keep your fish clean and will aid in maintaining the same texture while thawing.
- Then, place your plastic-wrapped fish in a bowl. Put this bowl under your tap, and start running a stream of cold water over your fish. This will create a convection effect, causing your fish to begin defrosting.
- While you can leave your fish (FULLY SUBMERGED) in the defrosting bowl for a short amount of time, using running cold water will speed up the process slightly as it increases the convection effect.
Defrosting using this method will generally take around half an hour, but if you’re defrosting a larger amount of fish this may vary. Adding around six to eight hours for every pound of fish is an easy way of predicting defrost time.
Once your fish is defrosted, take it out of the water and open the plastic wrap. Then, double check if it really is defrosted all the way through. If not, just place it back in the plastic and repeat until done. After cutting off the plastic wrap, quickly rinse the fish and dry it off with some paper towels.

What To Know Before Cooking Tilapia From Frozen
How Long To Cook Frozen Tilapia
When cooking tilapia from frozen, you want to leave the first third of the cooking time lower so that the fish can defrost evenly without cooking. The cook time will usually be increased by half of the original, non-defrost time, which will vary depending on the recipe you plan to use. If you’re cooking tilapia from frozen on the stove, keep the temperature very low at first and keep the lid on the pan. Looking for a recipe on cooking tilapia from frozen? In that case, be sure to check out the recipe at the end of this article.
How Long To Bake Frozen Tilapia
Baking tilapia from frozen is generally the same as cooking from frozen, but is better as your fish is less likely to heat unevenly. The same rule goes for cooking frozen tilapia in the oven – it will take around about half of your original cook time longer than usual. To make sure your fish heats all the way round, add tin foil (or a baking tray lid) to your fish.
I like to use something like this baking tray below, or a more expensive Le Creuset tray.

How To Cook Frozen Tilapia On The Stove
- Begin by following my prior instructions (listed under ‘How Do You Defrost Frozen Tilapia Quickly?’) for thawing tilapia. Alternatively, carefully wash your tilapia under slightly warm (NOT HOT) water, then dry off. Then, place your tilapia on a cutting board.
- Cut your tilapia into slices or ’steaks’, then oil and season both sides to taste – filtered and unfiltered olive oil, dill, lemon, and black pepper are popular choices for seasoning fish.
- Place your seasoned tilapia steaks into the pan and turn the heat up to the minimum. If you want to be extra safe, wrap each steak in tinfoil to ensure even and complete cooking. Either way, place the lid on the pan after adding the fish.
- Gradually turn the heat up to medium after the fish defrosts (should take roughly two – five minutes), then continue cooking for another five to ten minutes. If cooking without foil, cook until the inside is completely cooked and the outside is golden brown. You can check whether the inside is fully cooked by using a food thermometer.
- After fully cooked, plate your tilapia up and serve with whatever you’d like! Tobiko is a solid choice if you have it, but if not, don’t be afraid to use up leftovers! I find other seafood leftovers to fit the best, so be sure to check how long can that frozen shrimp really stay in the fridge or you might get some of the gnarlier side effects of eating shrimp.
