Lightly spray the tray in your air fryer with olive oil
Slice the zucchini into appx. 1/8 inch slices. Lay them out on a paper towel and lightly spray them with olive oil. Lightly sprinkle them with salt, pepper, dried parsley and garlic powder. Then generously cover with the grated parmesan.
Lay them out in the air fryer. It took our air fryer 8 minutes at 400°. And they were really good.
