Place the frozen chicken cordon bleu patties in your air fryer basket, spaced apart enough so they are not overlapping and to allow the air to flow around the chicken.
Air fry on 380 degrees F for 18-20 minutes until crispy on the outside and the internal temperature reaches 165 degrees F. (There is no need to spray the tops with cooking oil since the breading already includes oil and will release while cooking)
Some cheese might ooze out while cooking, that is perfectly ok. Just make sure to allow the chicken to rest a minute after cooking, the inside ham and cheese will be very hot.
