In a large mixing bowl, combine the beef, eggs, bread crumbs, onions, garlic, parsley, salt, and pepper. Using your hand combine all the ingredients until they are all well combined.
Form the mixture into a loaf form that will fit into your air fryer basket.
Place the meatloaf into the air fryer and set it to 380°F for 30 minutes.
In a small mixing bowl, whisk together the ketchup, brown sugar, Worcestershire sauce, and garlic powder. Brush the ketchup mixture over the top of the meatloaf and set it for another 10-15 minutes until the loaf reaches an internal temperature of 165°F.
Allow the meat to rest for 5-10 minutes before slicing.
