In a large mixing bowl, combine the ground chicken, breadcrumbs, green onions, grated Parmesan cheese, egg, soy sauce, sriracha, garlic powder, onion powder, salt, and black pepper. Mix well until all ingredients are fully combined.
Preheat your air fryer to 375°F (190°C).
Form the mixture into meatballs, about 1 inch in diameter, and place them on a baking sheet or plate.
Once the air fryer is preheated, arrange the meatballs in a single layer in the air fryer basket. Do not overcrowd – you'll likely need to cook them in batches.
Cook the meatballs in the air fryer for 10-12 minutes, flipping halfway through until they are golden brown and cooked through (internal temperature should reach 165°F or 74°C).
Remove the meatballs from the air fryer and let them rest for a few minutes. If desired, sprinkle with sesame seeds and chopped green onions before serving.
Serve hot with your favorite dipping sauce or over rice.
