Wash 1/2 lb chicken thighs under running water, and pat them dry with a paper towel. Cut them into approximately 2×1 inch pieces using a knife.
Dip each chicken piece into flour, then into the egg mixture, and finally into breadcrumbs. Set chicken pieces into a single layer in the air fryer basket or air fryer tray (spray the empty air fryer tray with olive oil, and then add chicken pieces).
Bake in an air fryer at 370 degrees F (188 degrees C) for about 20 minutes (check instructions for your air fryer type). Flip the chicken nuggets halfway through cooking to ensure even air frying.
