We cooked the pork chops in a 3.4 qt. Air Fryer
. For that size of air fryer, 3 pork chops is about the max without overcrowding the air fryer. If you have a larger size, you can probably cook 2-3 more so long as they are still in a single layer.
Adjust cooking time for thicker or thinner pork chops. Some brands of Air Fryers will cook slower or faster than others, adjust accordingly.
