How to Make Baked Tilapia
1. Preheat the Oven
Heat your oven to 400°F (200°C). Grease a baking dish with 1 tablespoon butter.
2. Season the Tilapia
In a bowl, combine the salt, pepper, paprika, and Italian seasoning.
Sprinkle the seasoning on both sides of each tilapia fillet.
Arrange the fillets in the prepared baking dish.
3. Make the Lemon Garlic Butter
Melt the remaining 4 tablespoons of butter in a small bowl.
Stir in the minced garlic and fresh lemon juice until combined.
4. Coat the Fish
Brush or spoon the lemon-garlic butter evenly over the seasoned fillets.
5. Bake
Bake for 10–12 minutes, or until the internal temperature reaches 145°F (63°C).
Check at the 10-minute mark—tilapia cooks quickly and can overcook easily.
The fish should flake apart easily with a fork when done.
6. Garnish & Serve
Top the baked tilapia with red pepper flakes (if using), fresh parsley, and lemon slices.
Serve warm and enjoy!
