Ingredients Equipment Method Notes

Ingredients
  

  • 4 cod fillets (about 6 oz each)
  • 1 tbsp olive oil
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1 tsp lemon zest
  • 3/4 cup finely chopped walnuts
  • 1/4 cup grated Parmesan cheese
  • 1/4 cup panko breadcrumbs
  • 1 tsp garlic powder
  • 1 tsp dried parsley
  • 1/2 tsp smoked paprika
  • 2 tbsp melted butter
  • lemon wedges for serving
  • fresh parsley, chopped for serving

Equipment

  • baking dish
  • sheet pan
  • parchment paper
  • mixing bowl
  • measuring cups and spoons
  • paper towels

Method
 

  1. Preheat the oven to 400°F. Lightly grease a baking dish or line a sheet pan with parchment paper.
  2. Pat the cod fillets dry with paper towels. Brush with olive oil and season with salt, black pepper, and lemon zest.
  3. In a bowl, combine chopped walnuts, Parmesan cheese, panko breadcrumbs, garlic powder, dried parsley, smoked paprika, and melted butter. Stir until evenly mixed.
  4. Press the walnut mixture firmly onto the top of each cod fillet.
  5. Arrange the fillets in the prepared baking dish.
  6. Bake for 12–15 minutes or until the fish flakes easily with a fork and the crust is golden brown.
  7. Serve immediately with fresh parsley and lemon wedges.

Notes

Pat the cod dry before adding the topping so the crust adheres properly. Avoid overbaking to keep the fish tender and flaky. Use finely chopped walnuts for the best texture. Add extra lemon juice before serving for fresh flavor. This recipe also works well with halibut, haddock, or salmon.
