Preheat the air fryer to 390°F. If your air fryer does not have a preheat setting, run it at 390°F for 5 minutes.
Trim the fat from the chicken breasts and cut them into 1-inch pieces.
In a small bowl, combine the Italian seasoning, pepper, salt, breadcrumbs, and Parmesan cheese.
Place the melted butter in a separate bowl.
Dip each piece of chicken in the melted butter, then coat it in the breadcrumb mixture.
Arrange the coated chicken in a single layer in the air fryer basket. Cook in batches if necessary.
Air fry for 10–12 minutes, until the nuggets are crispy and the chicken reaches an internal temperature of 165°F.
Serve warm with your favorite dipping sauce.

Notes
Refrigerate the leftovers in an air tight container for up to 5-7 days. To reheat, place them in the air fryer for 2-3 minutes to warm and crisp them back up. Enjoy!
