Step 1

Preheat the oven to 400ºF (205°C). Line a baking sheet with parchment paper or foil. Alternatively, a glass dish can be used for baking the fish.

Step 2

In a shallow bowl, mix together the Parmesan, Panko breadcrumbs (if using) paprika, parsley and salt (if using). Drizzle the cod with olive oil (rubbing it into the front and back of the fillet), then dredge the fish in the cheese mixture, pressing it in lightly with your fingers. Transfer to the baking sheet pan. Top cod with any leftover cheese mixture.

Step 3

Bake until the fish is opaque in the thickest part, 10-15 minutes. Serve with the lemon slices.
