Preheat the oven to 375°F (190°C) and grease your baking dish.

In a medium bowl, combine breadcrumbs, Parmesan cheese, garlic powder, onion powder, parsley, salt, black pepper, and paprika.

In another bowl, whisk together melted butter and lemon juice until well combined.

Dip each cod fillet in the butter mixture, then roll in the breadcrumb mixture.

Arrange the coated fillets in the greased dish and drizzle remaining butter and lemon mixture on top.

Bake for 20-25 minutes, until the cod flakes easily and the topping is golden brown.

Let the cod rest for a few minutes before serving.
