01 - Preheat oven to 400°F. Lightly grease a baking dish large enough to arrange cod fillets in a single layer.
02 - Place cod fillets in the prepared baking dish. Drizzle fillets evenly with lemon juice and spread Dijon mustard over the top of each fillet.
03 - In a mixing bowl, combine breadcrumbs, melted butter, parsley, paprika, minced garlic, salt, and black pepper. Stir until the breadcrumbs are evenly moistened.
04 - Spoon the seasoned breadcrumb mixture over each cod fillet, pressing gently so the topping adheres well.
05 - Transfer baking dish to oven. Bake 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 with lemon wedges alongside for squeezing over the top.
