Preheat the oven to 400 degrees F.
Use a kitchen towel to pat dry the cod filet and set it aside.
Prepare the breading station. In the first bowl, combine flour, salt, garlic powder, ground pepper, paprika, and Italian seasoning.
In the second bowl, combine eggs and splash of water, then whisk with a fork for a minute. Set aside.
In the third bowl, mix panko breadcrumbs and parsley and set aside.
Coat the cod filet in the flour mixture first, then dip them in the egg mixture. Finally, coat the filets in the breadcrumbs until evenly coated.
Place the filets on a baking tray lined with parchment paper. Spray the top of the filets with cooking spray.
Bake the cod in the oven for 12-15 minutes, or until it is cooked through.
Once done, garnish the cod filet with chopped parsley and lemon wedges on the side and serve it alongside with some greens.
