Oven Baked Tilapia
This tilapia recipe came out from being lazy at dinner one night. We had some fish in the fridge we needed to use, but I just did not feel like cooking much.
I put everything all in one pan so the only thing you need to chop is a lemon and some garlic (which I use my garlic chopper and toss it in the dishwasher afterward).
And, just because it’s simple doesn’t mean it’s not flavorful. The fillets bake in homemade garlic butter, lemon, and herb mixture that really packs a punch.

Tilapia in Oven Recipe Variations
- Herb-crusted: Mix some fresh herbs — like parsley, thyme, and dill — with breadcrumbs. Coat the fish in the mixture before baking to add flavor and texture!
- Mediterranean-style: Use olive oil instead of butter and incorporate extras such as chopped tomatoes, capers, black olives, and feta cheese into the baking dish for a fun Mediterranean twist.
- Italian-style: Add a layer of pesto sauce over the tilapia fillets before baking. Top with sliced tomatoes and fresh mozzarella cheese for a basil-infused variation.
- Cajun: This one is for my spice lovers! Rub some Cajun seasoning on both sides of the tilapia for a unique and flavorful kick.
Tips for Making Baked Tilapia in Oven
- Choose the freshest fish you can find. You don’t need a lot to make this baked tilapia recipe, so the quality of your ingredients really matters. This is even more true when it comes to cooking fish! Opt for fillets that are firm, moist, and odorless — they should not smell fishy.
- Melt the butter directly in the baking dish while your oven is heating. Don’t waste extra dishes by using your microwave. Also, the butter will melt fairly quickly as the oven starts to heat, so be sure to keep an eye on it.
- Watch for flakiness. Your tilapia will be baked and ready to enjoy after about 10-12 minutes but keep in mind that all ovens are different. The actual cooking time will also depend on the thickness of your tilapia fillets. Start checking after about 10 minutes. Use a fork to test the texture — they can be pulled out of the oven when they turn flakey.
What to Serve With This Tilapia in Oven
Because I like to make dinner a breeze on nights I make this dish, I make vegetables like bell peppers and zucchini or asparagus and carrots. White rice or roasted potatoes, garlic bread, and a big garden salad also make an easy full meal!
If you have any leftovers, I love to use them a filling for tacos, burritos, or a fish sandwich!
How to Store Leftover Oven Baked Tilapia
To store leftover baked tilapia, let it cool completely and transfer it to an airtight container. Refrigerate for 3-4 days, or freeze it for 2-3 months.
How to reheat Baked Tilapia in Oven
To reheat baked tilapia in the oven, preheat to 350 degrees F and place the fish on a baking sheet lined with parchment. Cover it loosely with foil to keep it from drying out, then heat for 10-15 or until warmed through.
Tilapia Recipe Baked FAQs
Should I rinse tilapia before cooking?
No, you should not rinse tilapia before cooking. In fact, you should never rinse fish, as you risk turning your sink into a breeding ground for germs.
If it has scales, you can go ahead and remove those; otherwise, you don’t need to rinse.
What temperature does Tilapia need to be cooked at?
To ensure it’s safe to eat, tilapia should be cooked to an internal temperature of 145 degrees F. 10-12 minutes at 400 degrees F in the oven will do the trick, but also use an Instant-Read thermometer to check.
Is fresh or frozen Tilapia best for this Baked Tilapia Recipe?
Fresh tilapia is best for this tilapia recipe! It will give you a much better flavor and texture than frozen food. That said, I’ve used frozen fish in a crunch. Thaw it in the fridge overnight before baking for the best results!
Can you overcook Tilapia?
Yes, tilapia can be overcooked. If you leave it in the oven for too long, it will become dry and tough. Keep a close eye on the cooking time—tilapia is relatively delicate and cooks quickly. Start checking on it after the 10-minute mark to prevent overcooking.
