Preheat and prep: Heat the oven to 425°F (220°C). Line a sheet pan with parchment or lightly oil it so the fish doesn’t stick.
Pat fish dry: Use paper towels to remove moisture from the tilapia.
Dry fillets help the crust adhere and crisp.
Mix the crust: In a bowl, combine Parmesan, breadcrumbs, garlic, lemon zest, parsley, melted butter, olive oil, salt, pepper, and paprika. Stir until the mixture looks sandy and holds together when pressed.
Season the fish: Sprinkle both sides of the tilapia with a little extra salt and pepper. Place on the prepared pan.
Top with the mixture: Divide the Parmesan crumb over the fillets, pressing it gently so it sticks.
Aim for an even layer so it browns uniformly.
Bake: Cook for 10–12 minutes, depending on thickness. The fish should flake easily with a fork, and the crust should be golden.
Optional broil: For extra color, switch to broil for 1–2 minutes at the end. Watch closely to avoid burning.
Finish and serve: Squeeze fresh lemon over the fish and garnish with more parsley if you like.
Serve hot with your favorite sides.
