While 400 Fahrenheit is a more popular choice, any of the temperatures are fine and will produce a great result.

As we said earlier, the standard cooking temperature for oven-baked tilapia fish is 350 and 400 Fahrenheit. 

Cooking time will vary at the same temperature depending on the size of the fish. If you choose to bake tilapia at 400 Fahrenheit, set your timer to 12-15 minutes. Small-sized tilapia fillets will be ready in 12 minutes while larger-sized ones will cook properly in 15 minutes. 

Likewise, at 350 Fahrenheit, smaller-sized tilapia fillets will be ready in 20 minutes and larger-sized tilapia fillets will have to cook for five additional minutes.

Because, tilapia cooks very quickly, your oven temperature is very important. Temperatures below 350 Fahrenheit will cook your tilapia slowly but will affect the tastes and texture of the result. Likewise, temperatures above 400 Fahrenheit may also cook your tilapia at less time but with a high risk of burning. Set your oven temperature to 350 Fahrenheit or 400 Fahrenheit.

Should I cook tilapia at 350 degrees or 400 degrees?

The recommended temperatures for cooking tilapia include 350, 375, 400 Fahrenheit. Any temperature within this range is fine and your tilapia will turn out tender and well-cooked for you to enjoy. Keep in mind that as the temperature varies, so does the time. 

Higher temperature means less cook time. Also, don’t go over 400 degrees Fahrenheit if you don’t want to burn your food. Temperature and time are very important especially with foods (like tilapia) that take a short time to cook.

If you wish to cook at 400 Fahrenheit, set your timer for 12-15 minutes. Or if you choose to cook at 350, set your timer for 20-25 minutes. This is enough to give you well-cooked tilapia and soft vegetables.

In both cases, to check for doneness, the internal temperature of your tilapia should measure 145 Fahrenheit. This is the safe eating temperature for tilapia fish.

Can I use frozen ingredients?

Frozen fish is a great way to store your protein. You may decide to buy your tilapia ahead of time or in bulk. The best way to preserve them is to put them in a freezer. Yes, you can use frozen tilapia. Frozen tilapia is safe because they are processed and frozen immediately after catch.

Fresh tilapia lasts in the refrigerator for only a few days. If you buy them frozen, they can last up to 2 months fresh in the freezer and you will always have them handy anytime you are ready.

You can buy frozen tilapia and simpy thaw before you cook or you can buy them fresh from the fish farm. Both of them work just fine. But it is better to buy them frozen because they are usually cheaper. 

How can I improve my recipe?

Vegetables for baked Tilapia

Cover your dish with aluminum foil before you slide your baking tray into the oven. This will make your tilapia juicier and more tender. But if you like the nicely browned tilapia, leave the aluminum foil and insert your fish without being uncovered. 

During purchase, avoid selecting any tilapia with a sour smell, dull color, and slimy texture!

Select a moist and resilient tilapia. They are fresh and healthy. You can buy the whole tilapia fresh and have it filleted for you at the store/farm.

Use small-sized individual baking dishes. These are convenient and go directly from the oven to the table. They also make a nice presentation! 

Final tips and tricks

Tilapia fish is low in carbs and high in protein, with a good amount of fat, which makes it Keto friendly. 

As a final note, bacon is not better than tilapia. The stories about the dangers of tilapia were due to some tilapia raised in China that were discovered to be fed manure rather than appropriate fish food. This doesn’t mean all tilapia is unsafe to eat or that bacon is better than tilapia. Tilapia is a pond farmed fish and it is safe to eat. If concerned, buy from reputable stores or ask for the U.S-raised tilapia.
