Mix the flour, parmesan cheese, garlic powder, salt and paprika if using, in a bowl.
Prepare the breading station with eggs, flour mix and breadcrumbs.

Place each breaded zucchini slice on the air fryer basket in a single layer. You will have to work in batches to cook all the zucchini.

Notes
I double dip the zucchini slices in the egg and flour mix so they will have a thick coating. You can also do only one. Just dip the slices in flour, then egg and finally in breadcrumbs.
Make sure you place the breaded zucchini slices in a single layer and cook in batches.
You can preheat the air fryer for about 3 minutes.
Leftovers can be kept in the fridge covered for 3 to 4 days. Reheat in the air fryer for 3 to 4 minutes.
