Set up a dredging station with two bowls — crushed pork rinds in one and eggs and milk in the other.
Coat each piece of chicken in pork rinds, submerge in egg wash and coat in pork rinds again.
Arrange chicken nuggets in a single layer in your air fryer, spray with cooking spray and cook for 8 minutes or until the internal temperature of the chicken is 165°F. Depending on the size of your air fryer you might need to fry them in two or more batches.
If you want them as crispy as possible you can flip them half way through the frying process, but as long as you spray them with cooking spray and don’t overload the air fryer basket by placing them in a single layer they get pretty crispy even without flipping them.
Let the nuggets cool and serve with ranch or your preferred dipping sauce.
