Ensure each chicken breast sits at room temperature for about 15 minutes before frying for even cooking. Pound uneven chicken breasts to a uniform thickness to help them cook evenly and stay juicy. If there's still pink inside the chicken, using a meat thermometer is key; it should hit 165 degrees F for safety. When the chicken ends up dry, timing is crucial; check for doneness and let it rest afterward. If browning is less than expected, giving each piece some space in the air fryer makes all the difference.
