Slice each chicken breast in the middle horizontally, creating 4 thinner pieces in total.

In a shallow bowl, whisk the eggs.

In another shallow bowl, mix together the panko breadcrumbs, salt, and black pepper.

Place the flour in a third shallow bowl.

Dredge each chicken piece in the flour, then dip into the egg mixture, and finally coat with the panko mixture, pressing gently to adhere.

Place the breaded chicken cutlets in the air fryer basket, ensuring they are not overlapping.

Spray the breaded chicken cutlets lightly with cooking spray.

Cook in the air fryer at 380°F (190°C) for 23 minutes, flipping halfway through the cooking time, until the chicken is golden brown and cooked through.

Once cooked, remove the chicken cutlets from the air fryer and let them rest for a few minutes before serving.
