01 - Preheat the oven to 400°F (200°C). Lightly grease a baking dish sized to hold the cod fillets in a single layer.
02 - Place the cod fillets in the prepared baking dish. Drizzle lemon juice over the fillets and spread Dijon mustard evenly across each portion.
03 - In a medium mixing bowl, combine the breadcrumbs, melted butter, chopped parsley, paprika, minced garlic, salt, and black pepper. Stir to evenly moisten the crumbs.
04 - Gently spoon the breadcrumb mixture over each fillet, lightly pressing so it adheres. Bake for 18 to 20 minutes, or until the cod is opaque, flakes easily with a fork, and the topping is golden brown.
05 - Serve the baked cod immediately with lemon wedges for additional flavor at the table.
