Preheat your oven to 400 degrees Fahrenheit and line a baking tray with foil, spraying it with non-stick cooking oil or butter.

If your walleye fillets are frozen, thaw them completely. Cut off the skin if necessary and pat the fillets dry with a paper towel.

Crack an egg into a shallow bowl and whisk it well to create a coating for the fish.

In a separate bowl, mix grated parmesan cheese with panko breadcrumbs and seasonings: garlic powder, onion powder, paprika, salt, and pepper.

Dip each fillet into the egg, making sure it’s completely coated, then transfer it to the breadcrumb mixture, coating it evenly on both sides.

Place the coated fillets on the prepared baking sheet, sprinkle any remaining dry mixture on top for extra flavor.

Bake the fillets in the preheated oven for about 15 minutes or until the fish is white and flaky and the coating is golden-brown.

Remove from the oven and squeeze fresh lemon juice over the fish before serving.
