If you have a smaller air fryer or are making a larger batch of meatballs, make sure you don't overcrowd the meatballs in the air fryer. Cook in batches if needed.
In large bowl mix together all the meatball ingredients (chicken, breadcrumbs, egg, Worcestershire sauce, onion powder, garlic powder, salt, and black pepper).
Lightly oil your hands to help keep the meat from sticking to your hands as you shape the meatballs.
Shape the meat into 12 evenly sized meatballs about the size of a heaping 1/8 cup (a medium cookie scoop also works great for forming the meatballs).
Preheat air fryer at 380°F/193°C for about 5 minutes.
Lightly spray the basket/tray of the air fryer with oil. Add the meatballs into an even layer. Spray the meatballs with oil to lightly coat.
Air Fry at 380°F/193°C for 8 minutes. Turn the meatballs over and then spray with additional oil if they look dry.
Increase heat to 400°F/205°C and continue to Air Fry for another 2-4 minutes or until cooked through and to your liking.
Serve on toothpicks or skewers for appetizers, and if desired add a BBQ sauce, teriyaki sauce, Buffalo sauce or any other preferred sauce. Or as a main dish, serve on pasta, rice, or in a sandwich.
