Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil for easy cleanup.

Step 2: Prepare the Coating

In a bowl, combine the grated Parmesan cheese, panko breadcrumbs, garlic powder, onion powder, smoked paprika, salt, and black pepper. Mix well to ensure the seasonings are evenly distributed.

Step 3: Make the Egg Mixture

In another bowl, whisk together the egg, Dijon mustard, and lemon juice until smooth. This mixture will help the Parmesan coating stick to the cod.

Step 4: Coat the Cod Fillets

Pat the cod fillets dry with paper towels. Dip each fillet into the egg mixture, ensuring it is evenly coated. Then, press it into the Parmesan mixture, covering all sides with the cheesy breadcrumb coating.

Step 5: Arrange on Baking Sheet

Place the coated cod fillets on the prepared baking sheet. Drizzle melted butter and olive oil over the top to help achieve a crispy, golden crust.

Step 6: Bake to Perfection

Bake the cod for 12-15 minutes, or until the fish is opaque and flakes easily with a fork. If you prefer a crispier crust, broil for an additional 1-2 minutes.

Step 7: Serve and Enjoy

Remove the cod from the oven and let it rest for a minute. Garnish with fresh parsley and serve with lemon wedges.
