Preheat your air fryer to 390°F. Coat the basket of your air fryer lightly with olive oil.
In a large mixing bowl, combine the egg and breadcrumbs. Let sit for 2-3 minutes to soften the breadcrumbs.
Add the ground chicken, Parmesan cheese, parsley, salt, pepper, garlic powder, and paprika. Mix gently until just combined, being careful not to overwork the meat.
Use a meatballer or tablespoon to form the mixture into 1 ½" balls. Roll the balls gently between dampened hands to shape.
Mist the meatballs lightly with olive oil spray, then arrange them in the air fryer basket.
Cook for 12-14 minutes, turning the meatballs halfway through the cooking process. The meatballs are done when the outside is browned and crisp and the inside reaches a temperature of 165°F. Remember, different air fryers cook differently, so check your meatballs starting around the 10 minute mark.
