01 - Preheat oven to 400°F (200°C). Lightly grease a baking dish large enough to hold the cod fillets in a single layer.
02 - Arrange the fillets in the prepared baking dish. Drizzle with lemon juice and evenly spread Dijon mustard over each fillet.
03 - In a mixing bowl, thoroughly blend breadcrumbs, melted butter, parsley, paprika, minced garlic, salt, and pepper until the mixture is evenly moistened.
04 - Distribute the breadcrumb mixture over each cod fillet, pressing gently to ensure it adheres.
05 - Bake for 18 to 20 minutes until the cod is opaque and flakes easily with a fork, and the breadcrumb topping turns golden brown.
06 - Serve hot with lemon wedges for squeezing over the fillets just before eating.
