01 - Preheat air fryer to 400°F for 5 minutes.

05 - Lightly spray both sides of each breaded chicken breast with olive oil spray.
06 - Place chicken in single layer in air fryer basket without overlapping. Cook in batches if necessary.
07 - Air fry at 400°F for 7 minutes.
08 - Flip chicken, spray lightly with oil again, and cook for 6-8 minutes until golden brown and internal temperature reaches 165°F.
09 - Let chicken rest for 2-3 minutes before serving to retain juices.
