01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly oil a baking dish.
02 - Pat the cod fillets dry with paper towels. Arrange them on the prepared baking sheet or dish. Brush each fillet with olive oil and season with salt and freshly ground black pepper.
03 - In a medium bowl, combine the fresh breadcrumbs, chopped parsley, grated Parmesan cheese, minced garlic, and lemon zest. Drizzle melted butter and olive oil over the mixture and stir until the breadcrumbs are thoroughly moistened.
04 - Evenly spoon the breadcrumb mixture over each cod fillet, gently pressing to ensure the topping adheres well.
05 - Bake the cod for 15 to 20 minutes until the fish flakes easily with a fork and the breadcrumb topping turns golden brown.
06 - Serve immediately with fresh lemon wedges.
