Line a large baking sheet with parchment paper.
Slice eggplant into ½ inch slices. Sprinkle salt on both sides of the eggplant slices and put them on a wire rack. Leave for 10 minutes to draw out excess moisture. Dry the eggplant slices.
Combine the breadcrumbs, parmesan, Italian seasoning, garlic powder, salt, and black pepper in a medium shallow bowl.
Place flour and beaten eggs each in separate shallow bowls
Dip each eggplant slice first in flour to completely coat, then shake off the excess flour.
Next, dip the coated eggplant slice in beaten eggs, and shake off the excess egg.
Finally, completely coat the eggplant slice in the breadcrumb mix. Set onto the prepared baking sheet.
Repeat the process for all remaining eggplant slices.
Preheat the air fryer to 375°F, air fryer setting, and spray the air fryer basket with cooking spray.
Spray eggplant slices on both sides with cooking spray and transfer them into the Air Fryer basket in a single layer. Cook in the Air Fryer for 8-10 mins, until pale golden brown and crispy.
Top the cooked eggplant slices with marinara sauce and a slice of mozzarella cheese.
Cook for a further 1-2 mins until the cheese melts.
Serve immediately as a snack or with some pasta or salad as part of a full meal.
Garnish with chopped fresh basil/parsley (optional)
Plate, serve, and enjoy!
