Step 1: Preheat the oven to 400°F (200°C) and prepare a baking sheet or dish with parchment paper or light oiling.
Step 2: Pat the cod fillets dry and season with salt and pepper.
Step 3: Place the fillets in the baking dish and brush with olive oil or butter to keep them moist.
Step 4: Prepare the crust by mixing breadcrumbs, Parmesan, butter, garlic, parsley, herbs, lemon zest, lemon juice, salt, and pepper in a bowl.
Step 5: Spread the breadcrumb mixture evenly over each cod fillet, pressing gently so it adheres.
Step 6: Bake the cod in the preheated oven for about 12–15 minutes, depending on thickness.
Step 7: Optionally, broil the fish for 1–2 minutes at the end to create a perfectly golden crust.
Step 8: Serve hot with fresh lemon wedges and a sprinkle of herbs.
