Preheat the oven to 400°F. Line a baking tray with foil or parchment paper and lightly grease it.
Pat the tilapia fillets dry on both sides with paper towels. This helps the crust stick and keeps the fish from steaming in the oven. If you are starting from frozen, thaw the fillets fully and blot them dry first.
2 pieces tilapia fillets
In a shallow bowl, combine the grated Parmesan cheese, garlic powder, ground black pepper, sea salt, and Italian breadcrumbs. Mix until everything looks even.
1/2 cup grated Parmesan cheese, 1 teaspoon garlic powder, 1/4 teaspoon ground black pepper, 1/2 teaspoon fine sea salt, 1/4 cup Italian breadcrumbs
Rub olive oil all over both sides of each tilapia fillet.
2 tablespoons olive oil
Press each fillet into the Parmesan mixture, coating both sides well. Press the mixture gently into the fish so it stays in place while baking.
2 pieces tilapia fillets, 1/2 cup grated Parmesan cheese
Arrange the coated tilapia on the prepared baking tray, leaving a little space between the pieces.
Bake for 12 to 15 minutes, or until the crust is golden and the fish flakes easily with a fork. For a deeper brown, run the broiler for the last 1 to 2 minutes and watch it closely.
Let the fish rest for 2 minutes before moving it from the tray so the crust sets. Serve hot with rice, salad, roasted vegetables, or any simple side you already have.
