1Slice the eggplant into 1/4-inch (6 mm) rounds. Place in a colander or on a tray, sprinkle with salt, and let sit for at least 15 minutes to draw out excess moisture. Pat dry with paper towels.
2Preheat the air fryer to 375°F (190°C).
3Place the beaten egg in a small bowl.
4In another bowl, mix the Italian breadcrumbs, grated Parmesan, garlic powder, and dried basil.
5Dip each eggplant round first into the egg, then into the breadcrumb mixture, ensuring it is well coated on all sides.
6Arrange the eggplant rounds in the air fryer basket in a single layer without overlapping. Lightly spray with cooking spray.
7Cook for 8–10 minutes, spraying with oil and turning halfway, until golden and crispy.
8Top each round with a teaspoon of marinara sauce and a sprinkle of shredded mozzarella.
9Close the air fryer and cook for another 1 minute. Then turn off the appliance and let the eggplant sit for an additional minute to allow the cheese to melt completely.
10Serve immediately.
