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 - Place cod fillets in prepared baking dish. Drizzle fillets with lemon juice and spread Dijon mustard evenly over each portion.
03 - In a medium mixing bowl, blend breadcrumbs, melted butter, chopped parsley, paprika, minced garlic, salt, and pepper. Stir thoroughly until breadcrumbs are uniformly moistened.
04 - Distribute breadcrumb mixture evenly atop each cod fillet, pressing gently to ensure adherence.
05 - Bake for 18 to 20 minutes, until cod is opaque and flakes easily with a fork and the topping becomes golden brown.
06 - Serve immediately with lemon wedges for additional brightness.
