01 - Set oven to 400°F. Lightly grease a baking dish large enough to fit cod fillets in a single layer.
02 - Place cod fillets in the prepared baking dish. Drizzle with lemon juice and evenly spread Dijon mustard on top of each fillet.
03 - In a mixing bowl, blend together breadcrumbs, melted butter, parsley, paprika, minced garlic, salt, and pepper. Stir until the mixture is evenly moistened.
04 - Spoon the breadcrumb mixture over each cod fillet, pressing gently to adhere the topping.
05 - Bake for 18 to 20 minutes, or until the cod is opaque and flakes easily with a fork and the breadcrumb topping is golden brown.
06 - Serve hot, garnished with lemon wedges for squeezing over the fish.
