01 - Preheat the oven to 400°F (200°C). Lightly grease a baking dish large enough to hold the cod fillets in a single layer.
02 - Arrange the cod fillets in the prepared baking dish. Drizzle each fillet with fresh lemon juice and spread Dijon mustard evenly over the top.
03 - In a medium mixing bowl, combine breadcrumbs, melted unsalted butter, chopped parsley, paprika, minced garlic, salt, and black pepper. Mix thoroughly until the breadcrumbs are evenly moistened.
04 - Spoon the breadcrumb mixture evenly over each cod fillet, pressing gently to ensure it adheres to the surface.
05 - Transfer the dish to the preheated oven and bake for 18 to 20 minutes, or until the cod is opaque, flakes easily with a fork, and the topping turns golden brown.
06 - Serve the baked cod hot, garnished with lemon wedges for squeezing over the top.
