Preheat the oven to 400°F (205°C). Line a baking sheet with parchment paper.

Rinse the fish and remove any pin bones.

In a bowl, combine 1 teaspoon of melted butter, cheese, garlic powder, bread crumbs, parsley, and paprika. This will be the flavorful cheesy topping for your tilapia.

Place the fish on the prepared baking sheet. Brush the remaining 1 tablespoon of melted butter on the tilapia fillets on the baking sheet and then squeeze the lemon on top.

After the butter and the lemon, add the cheesy topping to each fillet. Make sure to spread it nice and evenly.

Bake for 10 to 15 minutes, until the fish flakes easily and is cooked through.
