01 - Preheat oven to 400°F (200°C). Lightly grease a baking dish large enough to fit cod fillets in a single layer.
02 - Place cod fillets in the prepared baking dish. Drizzle with lemon juice and spread Dijon mustard evenly on top.
03 - In a mixing bowl, blend fresh breadcrumbs, melted butter, parsley, paprika, minced garlic, salt, and black pepper until breadcrumbs are uniformly moistened.
04 - Spoon the breadcrumb mixture over each fillet, gently pressing to adhere.
05 - Bake uncovered for 18–20 minutes, until fish is opaque, flakes easily with a fork, and the topping turns golden brown.
06 - Serve immediately with lemon wedges for squeezing over the top.
