In a third bowl, combine the panko bread crumbs, parmesan cheese, garlic powder and Italian seasoning.
Dip each zucchini slice into the flour, followed by the egg mixture, and then the bread crumb mixture, pressing gently to coat.
Spray the air fryer basket with cooking spray. Add the zucchini to the basket in a single layer and cook at 400°F for 8 minutes, flipping halfway through.

Notes
Storage: Store any leftovers in an airtight container in the fridge. Cooked zucchini chips will keep well for around 4 days. You can reheat them in the air fryer at 400ºF for 2 to 3 minutes before serving serve.
