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