Preparation Time & Servings

Ingredients

Tilapia

Optional Garnishes

Recipe Note: Salt, pepper, garlic, lemon, herbs, butter, and seasonings can all be adjusted according to your personal taste preference. Fresh lemon juice gives the brightest flavor, while butter creates a richer finish than olive oil.

How to Make Oven Baked Tilapia

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Lightly grease a baking dish or line a baking sheet with parchment paper for easy cleanup.

Step 2: Prepare the Fish

Pat the tilapia fillets dry with paper towels to remove excess moisture. This helps the seasonings stick better and allows the fish to bake evenly.

Step 3: Make the Seasoning Mixture

In a small bowl, whisk together the olive oil or melted butter, minced garlic, lemon juice, lemon zest, smoked paprika, garlic powder, onion powder, Italian seasoning, salt, and black pepper until well combined.

Step 4: Season the Tilapia

Arrange the tilapia fillets in a single layer in the prepared baking dish. Brush the seasoning mixture generously over both sides of each fillet so every piece is evenly coated.

Step 5: Bake

Bake the tilapia for 15–18 minutes, depending on the thickness of the fillets. The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Step 6: Garnish

Remove the fish from the oven and sprinkle with chopped parsley, grated Parmesan cheese, or a pinch of red pepper flakes if desired. Add fresh lemon slices for extra brightness.

Step 7: Serve Immediately

Serve the tilapia while it’s hot with steamed vegetables, rice, roasted potatoes, or a crisp green salad. Spoon any juices from the baking dish over the fish for even more flavor.

Avoid overcooking during reheating, as the fish can become dry. Freezing is possible for up to 2 months, although the texture is best when enjoyed fresh.
