Patting the fish dry and salting it lightly helps to firm up the fish and adds flavor from the start. For extra crunch, use panko breadcrumbs. Cook in batches if needed to avoid overcrowding the air fryer. Leftovers can be refrigerated for up to 2 days or frozen for up to 1 month. Reheat in air fryer for best results. Variations include adding spices, herbs, Parmesan, or lemon zest for different flavors.
