Prepare the Meatball Mixture – Combine ground chicken, egg, cornstarch, minced garlic, ginger, soy sauce, and seasonings. Mix gently by hand to combine without overworking, which keeps meatballs tender.
Shape Uniform Meatballs – Form the mixture into evenly sized meatballs about 1 to 1.5 inches in diameter. Consistency ensures even cooking and prevents some meatballs from under- or overcooking.
Preheat the Air Fryer and Arrange Meatballs – Heat the air fryer to the recommended temperature. Place meatballs in a single layer without overcrowding to ensure crispiness on all sides.
Air Fry Until Golden and Cooked Through – Cook the meatballs until they develop a golden, crispy exterior and reach an internal temperature of 165°F (74°C). Spritz occasionally with oil if desired to boost browning.
Make the Honey Sesame Sauce – In a small pan, whisk together honey, soy sauce, sesame oil, garlic, and ginger. Simmer briefly to reduce and thicken for a glossy finish.
Toss Meatballs with Sauce and Serve – Transfer hot meatballs to the sauce and toss to coat evenly. Garnish with toasted sesame seeds and sliced green onions for added flavor and presentation.
