  • 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.

Frequent Questions

What is tilapia?

Tilapia is a freshwater fish commonly used in cooking. It has a mild, white flesh and is known for its versatility. Tilapia is often chosen for its neutral flavor, making it a popular choice in various recipes, including this one. It’s readily available in most supermarkets and seafood markets.

Can I substitute tilapia with another fish?

Yes, you can substitute tilapia with other mild white fish like cod or sole for a similar result.

Can I use salted butter instead of unsalted butter?

While unsalted butter is recommended, you can use salted butter, but be mindful of the overall saltiness since Old Bay seasoning already contains salt.

Is it okay to skip Old Bay seasoning if I don’t have it?

You can make your own spice blend, but it won’t replicate the exact flavor of Old Bay. It’s a key ingredient for the recipe’s unique taste. Try other blends such as Cajun Seasoning or a paprika & celery salt blend.

Can I use frozen tilapia fillets?

Frozen tilapia can be used, but thaw them completely and pat them dry before following the recipe.

Can I use garlic powder instead of fresh garlic?

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.

  • 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.
