01 - Preheat oven to 400°F (200°C). Lightly grease a baking dish large enough to arrange the cod fillets in a single layer.
02 - Place the cod fillets in the prepared baking dish. Drizzle evenly with lemon juice and spread Dijon mustard on top of each fillet.
03 - In a medium mixing bowl, combine breadcrumbs, melted butter, parsley, paprika, minced garlic, salt, and black pepper. Mix until breadcrumbs are evenly moistened.
04 - Spoon the breadcrumb mixture over each cod fillet, pressing gently so the coating adheres.
05 - Bake for 18 to 20 minutes, or until cod is opaque and flakes easily with a fork, and topping is golden brown.
06 - Serve hot, accompanied by lemon wedges for squeezing over the fish.
