About this Recipe
If you’re new to making seafood, this baked fish recipe is a great place to start. Tilapia has a mild, but delicious taste without a lot of fishy taste. So, even those who don’t love seafood will probably enjoy it because the fish absorbs the flavor from the blend of lemon, garlic, baked around it.
Ingredients
- 2 Lemons: One of the major ingredients in this recipe is the slices of fresh lemon. As it bakes, the slices leak lemon juice that mixes with the butter and gets absorbed into the fish for lemon flavor. Feel free to garnish with lemon zest for an extra zing!
- 4 Tilapia Fillets: It is a mild and flaky white fish. It serves as the main protein in this dish, absorbing the flavors of the garlic butter and Old Bay seasoning. You can use other white fish fillets like cod or sole as alternatives. Bonus points if you’re using wild-caught fish!
- 4 tablespoons Unsalted Butter: Butter adds richness and a creamy texture to the dish. When melted, it coats the tilapia and infuses it with a buttery flavor.
- 2 teaspoons Old Bay Seasoning: Old Bay Seasoning is a bold blend of spices that typically includes celery salt, paprika, and red pepper. It provides a savory and slightly spicy flavor, enhancing the overall taste of the dish. You can make your own spice blend if Old Bay is not available, but it won’t be exactly the same.
- 2 cloves Garlic: Garlic adds a robust and aromatic flavor to the butter sauce. It complements the fish and lemon, creating a harmonious combination. You can adjust the amount of garlic to suit your taste preferences.
Can this be made ahead of time?
This recipe is best enjoyed fresh out of the oven to maintain its optimal texture and flavor. While you can prepare some components in advance, such as slicing lemons or mixing the butter sauce, it’s recommended to assemble and bake the dish just before serving for the best results.
What to Pair with Garlic Butter Baked Tilapia
While the delicious meal is cooking in the oven, you can get to work on prepping some simple and delicious sides. This fish dish would taste amazing with vegetables like Sauteed Green Beans, or Mushrooms. You can also add a side of creamy and filling Mashed Potatoes. Once you have the meal ready, you can serve it up with the side dishes and drizzle any extra garlic lemon sauce over the sides.
How to Store
- Store: If you have any leftovers from this weeknight dinner recipe, don’t leave it out for more than an hour or two. To store leftover fillets, you can cover the dish with foil, or transfer them to an airtight container. Then store it in the fridge for up to 3 days.
- Reheat: When you’re ready to reheat the tilapia, take the airtight container out of the fridge or freezer. Then lay the fillet on a baking sheet and reheat for 7-10 minutes in a 450-degree oven, or 370º in the toaster oven until warmed through 5-7 minutes.
- Freeze: Leftovers can also make a great meal prep meal. Once the fillets have cooled transfer them to serving serving-sized meal prep container. As long as they’re carefully sealed, frozen tilapia fillets can stay good for up to 3 months.
Frequent Questions

Frozen tilapia can be used, but thaw them completely and pat them dry before following the recipe.
Fresh garlic provides better flavor, but you can use garlic powder as a substitute. Use ½ to 1 teaspoon of garlic powder per clove as a rough guideline.
Variations
- Seasonings: You can easily experiment with the flavor of Lemon Butter Tilapia by adding different kinds of fresh herbs and spices. You can add an herb mixture to the butter sauce with ingredients like flat-leaf parsley, fresh dill, or rosemary. Spices like black pepper, garlic powder, onion powder, chili powder, cayenne pepper, or a dash of paprika powder would also taste great sprinkled on top.
- Crusted Tilapia: To add a delicious crispy coating to the Baked Tilapia, you can use a cracker crumb, panko breadcrumb, or parmesan coating. Start by brushing the butter mixture over the fish fillets. Then toss them in the crumbs mixture until they’re coated. Place the fillets back in the baking dish and bake as usual.
- Lime Tilapia: You could also make more of a tangy and spicy fish dish. Replace the lemons with limes at the bottom of the pan. Then lay the fish over the top. Add ¼ teaspoon cayenne pepper to the butter mixture and spoon it over the lime fillets. These ingredients give the Tilapia more of a bold Southwestern-inspired flavor.
