Ingredients

• 4 tilapia fillets (6 ounces each)
• 3 tablespoons butter, melted
• 3 tablespoons lemon juice
• 1 1/2 teaspoons garlic powder
• 1/8 teaspoon salt
• 2 tablespoons capers, drained
• 1/2 teaspoon dried oregano
• 1/8 teaspoon paprika

How to Make Baked Tilapia

1. Prepare the Oven and Baking Dish

Preheat your oven to 400°F (200°C).

Lightly grease a baking dish large enough to hold the four tilapia fillets in a single layer.

Pat the tilapia dry with paper towels and place the fillets in the prepared dish.

2. Make the Lemon Butter Mixture

In a small bowl, whisk together the melted butter, lemon juice, garlic powder, salt, dried oregano, and paprika.

Pour the mixture evenly over the tilapia fillets.

Scatter the drained capers over the top.

3. Bake the Tilapia

Bake uncovered for about 12–15 minutes, depending on the thickness of the fillets.

The fish is ready when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C) at the thickest part.

Avoid overbaking, as tilapia can become dry if cooked too long.

4. Serve

Remove the tilapia from the oven and spoon some of the lemon-butter juices from the baking dish over each fillet.

Serve immediately with your favorite side dishes.

Recipe Tips for Success

• Pat the fish dry first. This helps the butter and seasonings coat the fillets evenly.
• Choose fillets of similar thickness so they finish cooking at roughly the same time.
• Don’t overbake the fish. Tilapia cooks quickly and is best when just flaky.
• Use fresh lemon juice for the brightest flavor.
• Drain the capers well so they don’t add too much extra liquid to the dish.
• For the best results, use an instant-read thermometer to check the thickest part of the fish.

Ingredient Substitutions

• Tilapia: Cod, haddock, pollock, or another mild white fish can be used.
• Butter: Olive oil can be substituted for a lighter option.
• Fresh lemon juice: Bottled lemon juice works in a pinch, although fresh has better flavor.
• Garlic powder: Use 2–3 minced garlic cloves for a stronger fresh garlic flavor.
• Capers: Chopped green olives can provide a similar salty, briny note.
• Oregano: Italian seasoning can be used instead.

Recipe Variations

Garlic Lemon Tilapia

Replace the garlic powder with fresh minced garlic for a more pronounced garlic flavor.

Parmesan Tilapia

Sprinkle grated Parmesan over the fillets during the last few minutes of baking for a cheesy finish.

Spicy Baked Tilapia

Add a pinch of cayenne pepper or crushed red pepper flakes to the lemon-butter mixture.

Herb Baked Tilapia

Add fresh parsley, dill, or basil after baking for a fresh herbal finish.

Mediterranean-Style Tilapia

Add sliced cherry tomatoes, olives, and thinly sliced red onion around the fish before baking.

How to Store

Allow leftover tilapia to cool, then transfer it to an airtight container.

Refrigerate for up to 3 days.

Reheat gently in a 300°F oven or microwave until just warmed through. Avoid overheating, which can dry out the fish.

Can You Freeze Baked Tilapia?

Yes. Allow the cooked tilapia to cool completely, then wrap each fillet tightly and place it in a freezer-safe container.

Freeze for up to 2 months for the best quality.

Thaw overnight in the refrigerator and reheat gently.

Frequently Asked Questions

How do I know when tilapia is done?

Tilapia should be opaque and flake easily with a fork. For food safety, the thickest part should reach 145°F (63°C).

Can I use frozen tilapia?

Yes. For the best texture, thaw the fillets completely in the refrigerator and pat them dry before baking.

Can I use olive oil instead of butter?

Yes. Olive oil works well in place of butter and gives the dish a lighter flavor.

Why did my tilapia turn out dry?

Tilapia is a lean fish and can dry out when overcooked. Start checking the fish around the 12-minute mark, especially if your fillets are thin.

Can I prepare the fish ahead of time?

You can prepare the lemon-butter mixture and season the fish several hours ahead. Keep the uncooked fish refrigerated and bake just before serving.

What other fish can I use?

Cod, haddock, pollock, and other mild white fish are good alternatives. Cooking time may vary depending on the thickness of the fillets.
