Preheat your air fryer to 375°F.
In a large bowl, combine ground chicken, egg, panko breadcrumbs, Italian seasoning, salt, black pepper, and fresh parsley. Mix thoroughly until all ingredients are evenly distributed.
With your hands or a cookie scoop, form small portions of the meat mixture into meatballs, approximately 1 to 1.5 inches in diameter. Ensure uniform size for consistent cooking.
Lightly grease the air fryer basket with cooking spray or a small amount of oil. Arrange meatballs in a single layer in the basket, ensuring they do not touch for proper air circulation.
Cook meatballs in the preheated air fryer for 15-18 minutes, flipping halfway through cooking. You can use a meat thermometer to ensure the meat temperature reaches 165°F to ensure thorough cooking.
After cooking, cut open one meatball to confirm it is cooked through and no longer pink in the center.
Once cooked, remove these juicy chicken meatballs from the air fryer. Serve hot as an appetizer with your favorite dipping sauce, or a main dish over pasta with marinara sauce.
Optionally, garnish with additional fresh parsley or grated Parmesan cheese.
