01 - Preheat the oven to 400°F. Lightly grease a baking dish large enough to hold the cod fillets in a single layer.
02 - Place the cod fillets into the prepared baking dish. Drizzle with lemon juice and evenly spread Dijon mustard across the fillets.
03 - In a medium mixing bowl, combine breadcrumbs, melted butter, parsley, paprika, minced garlic, salt, and black pepper. Stir until the breadcrumbs are evenly moistened.
04 - Spoon the breadcrumb mixture over each cod fillet, pressing gently to form an even layer.
05 - Bake in the preheated oven for 18 to 20 minutes, or until the cod is opaque and flakes easily with a fork, and the breadcrumb topping is crisp and golden brown.
06 - Serve hot, garnished with lemon wedges for squeezing over the top.
