Usually, yes. There is quite a thin line between undercooked and overcooked chicken, so it can be tricky to get right. Making grilled chicken in the air fryer is an excellent way to avoid overcooking chicken because the air fryer cooks quickly and evenly, ensuring that the moisture in the meat isn't lost as it is more easily with other cooking methods. It's also good to use a meat thermometer to tell you when your chicken is cooked. Chicken is safe to eat once it's reached an internal temperature of 165°F. Much more than that, and it will probably be overcooked.
