Preheat an air fryer to 400 degrees F (200 degrees C).

Place pork chops on a plate and season both sides with Cajun seasoning.

Pulse croutons in a small food processor until fine; transfer to a shallow dish. Lightly beat eggs in a separate shallow dish. Working one at a time, dip pork chops into beaten egg, letting excess drip off; press into crouton breading to coat both sides and place breaded chop, unstacked, onto a plate. Repeat with remaining chops. Mist chops with cooking spray.

Spray the air fryer basket with cooking spray and arrange chops in a single layer in the air fryer basket. You may have to do two batches depending on the size of your air fryer.

Cook in the preheated air fryer for 5 minutes; flip chops and mist again with cooking spray if there are dry areas. Cook 5 minutes more. An instant-read thermometer inserted into the center of the chops should read 145 degrees F (63 degrees C).
