Preheat your air fryer to 375°F (190°C).
Set up your breading station: flour, beaten eggs, and a mixture of breadcrumbs, Parmesan, and Italian seasoning.
Dip each eggplant slice in flour, then egg, then breadcrumb mixture.
Spritz the air fryer basket with olive oil spray. Place breaded eggplant slices in a single layer.
Spritz the tops of the eggplant with olive oil spray.
Air fry for 8-10 minutes, flipping halfway through, until golden brown and crispy.
In an oven-safe dish, layer sauce, eggplant, and mozzarella cheese.
Return to the air fryer for 2-3 minutes until the cheese is melted and bubbly.
