Place the flour in a bowl with the Italian Seasoning, chicken seasoning, and salt and pepper to taste. Stir to combine.
Add the egg to a separate bowl and beat.
Add the breadcrumbs to a third bowl.
Dip the sliced chicken in the seasoned flour, then the egg, and last the breadcrumbs. Place the chicken on a clean surface. Note: Your hands will get very sticky. Keep a moistened paper towel handy to wipe your hands.
Spray the breaded chicken with cooking oil. Keep a safe distance from the chicken so that the spray does not send the breading flying. I like to spray both sides of the nuggets while they are on a flat surface before loading them into the air fryer. This ensures each is properly coated.
Place the nuggets in the air fryer. Do not overcrowd the basket. Consider cooking them in batches if you have a small air fryer basket.
Cook for 4 minutes on 400 degrees.
Open the air fryer and flip the nuggets. I used tongs instead of shaking the basket.
Cook for an additional 4 minutes.
Open the air fryer and examine the nuggets to determine if they have reached your desired level of crisp. I cooked mine for an additional 5 minutes at this point.
Remove the nuggets and serve.
