The answer to this question depends on how thick the fillets are.

  • If they’re thin, you’ll only need to bake them for about 15-20 minutes at 400 degrees Fahrenheit.
  • But if they’re thicker, you’ll need to bake them for closer to 25 minutes. 
  • If you use frozen tilapia fillets, you must increase the baking time by a few minutes.

Don’t Overcook

Another thing to remember is that you don’t want to overcook the fish, or it will dry out.

So, check on it after 15 minutes and then every few minutes until it’s done. The flesh will be opaque when cooked through and flake easily with a fork.

  4. That’s it! Your dish is now ready to enjoy. Serve with your favorite sides, and enjoy! 

About Tilapia

It is a flaky white fish commonly enjoyed for its deliciously mild flavor and flaky texture. This fish is a great source of protein and essential vitamins, making it an excellent choice for anyone looking for a healthy meal.

Baking is an excellent option because it’s simple and easy, resulting in a moist fish packed with flavor.

Tips

  • Ensure the fish is at room temperature before you bake it. If it’s straight from the fridge, it will take longer to cook.
  • Preheat your oven to 400 degrees Fahrenheit.
  • Use an oven-safe baking dish or sheet. I like to put foil down first to be safe. 
  • Opt for thinner fillets, as they’ll cook more quickly.

FAQs

Can I substitute another type of fish for the tilapia?

Yes. Any firm white-fleshed fish will work well in this recipe. My personal favorites are cod, halibut, and swordfish. But feel free to experiment with other types of fish as well.

Can I bake the tilapia in a different type of oven (convection, toaster, etc.)?

Yes, you can, but you may need to adjust the cooking time and temperature.

Convection ovens cook food more quickly and at a lower temperature than traditional ovens, so you may want to reduce the cooking time by a few minutes.

Toaster ovens cook food faster than traditional ovens, so you may want to increase the cooking time by a few minutes.

How do I know when the tilapia is fully cooked?

You can tell by checking the color. The flesh should be opaque and white, not pink or translucent.

You can also test for doneness by inserting a fork into the thickest part of the fish and pulling it gently apart; if the fish flakes easily, it’s done.

Can I add additional seasonings or marinades to the tilapia before baking?

You could add it, but you don’t want to add too much liquid because the fish will release moisture as it cooks.

A light misting of olive oil or cooking spray is all you need. You could also try herbs such as dill, parsley, basil, or lemon pepper.

Can I bake the tilapia in foil or on a sheet pan?

Yes, you can. For baking in foil, place the fish on a double layer and fold up the edges to create a pouch.

For baking on a sheet pan, spray it with cooking spray or brush it with olive oil, place the fish on the pan, and bake for about 15 minutes or until it is cooked.

Can I bake multiple tilapia fillets at once?

Yes! To bake multiple fillets at once, preheat your oven to 400 degrees F and line a baking sheet with parchment paper.

Place the fillets on the baking sheet, ensuring they’re not touching each other, and bake for 15-20 minutes or until cooked through.

Can I bake frozen tilapia instead of thawing it first?

It is not recommended as it may not cook evenly and taste as good. Always thaw the fish before baking for optimal results.
