01 - Set oven to 400°F. Line a baking sheet with parchment paper or lightly oil a baking dish.
02 - Pat cod fillets dry with paper towels. Season both sides with salt and freshly ground black pepper. Arrange fillets on the prepared baking sheet.
03 - In a mixing bowl, combine fresh breadcrumbs, chopped parsley, chives, dill, lemon zest, minced garlic, and olive oil. Stir until evenly moistened.
04 - Brush a thin, even layer of Dijon mustard over the top surface of each cod fillet.
05 - Press the herb breadcrumb mixture onto the mustard-coated side of each fillet, ensuring an even and gentle coverage.
06 - Place fillets in the oven and bake for 15 to 20 minutes until the fish flakes easily with a fork and the crust turns golden brown.
07 - Immediately serve the baked cod with lemon wedges on the side.
