Pat the eggplant with a paper towel to remove excess moisture. Place the eggplant in a single layer in the air fryer and cook at 400 degrees for 2 minutes. Then flip the eggplant for 2 minutes and cook.
Spread the sauce evenly over the eggplant. Top with cheese and pepperoni and sprinkle with italian seasoning.
Cook for 5 more minutes or until the cheese is bubbly and lightly brown on the top.
