Slice zucchini into ¼"-½" slices.
In a small bowl, mix flour, salt and pepper. In a second bowl, add eggs and beat with a fork. In a 3rd bowl, combine panko bread crumbs and parmesan.
Dip a zucchini slice in flour and shake off excess. Next dip in beaten eggs and remove excess. Then dip in panko/parmesan and press down to coat both sides completely.
Place coated zucchini slice in air fryer basket. Repeat with remaining zucchini slices and place in air fryer basket in a single layer. Spray zucchini slices with non-stick cooking spray. Flip over and spray other side.
Air Fry at 375 for 6 minutes. Flip over and cook for another 5 minutes or until golden brown.
