Preheat the air fryer to 375°F.
In a shallow dish, mix flour, salt, pepper, and lemon zest.
In a separate bowl, whisk the eggs until well combined.
Place panko breadcrumbs in another dish.
Dredge each chicken breast in the flour mixture, ensuring it is fully covered.
Dip the chicken into the beaten eggs.
Coat the chicken in the panko breadcrumbs, pressing gently to adhere.
Spray the air fryer basket with olive oil.
Lay the chicken inside, ensuring they do not overlap.
Spray the tops of the chicken with more olive oil.
Air fry the chicken for 6 minutes, then flip and cook for another 6 to 8 minutes or until golden brown and the internal temperature reaches 165°F.
Allow the chicken to rest for 5-10 minutes before serving.
