Preheat the Air Fryer to 380 degrees F.
Wash and dry the eggplant with a kitchen towel. Using a knife, slice the eggplant into about ⅓ inch thick slices.
Prepare the breading station: In the first bowl, place the all-purpose flour; in the second bowl, whisk the eggs, and in the third bowl, combine panko breadcrumbs, regular breadcrumbs, parmesan cheese, Italian seasonings, garlic powder, salt, and pepper. Set it aside.
Dip the eggplant slices in the flour first and then into the egg mixture, and finally, dredge them into the breadcrumb mixture and gently press it until evenly coated. Repeat the same with the remaining eggplant slices.
Spray each side of the eggplant with cooking spray and place the eggplant in a single layer on an air fryer basket. Air fry them for 10 minutes, flip them halfway through, and cook until the eggplants turn golden and crispy.
Once done, transfer the eggplants to a serving platter, garnish with parsley, and serve it with marinara sauce.
