In a small bowl combine the gluten free panko bread crumbs, parmesan cheese, lemon zest, cilantro and chili flakes. Transfer the mixture onto the third plate.
Place the asparagus in the air fryer basket in one layer. Cook at 400 degrees for 20 minutes or until the breadcrumbs turns golden in color.
