In one bowl (or a zip-top bag), mix the flour with 1 teaspoon of the seasoned salt.
In a second bowl, whisk the eggs together until well beaten.
In a third bowl, combine the panko, Parmesan cheese, and the remaining ¼ teaspoon of seasoned salt. Stir to combine. Add in the olive oil and stir until the crumbs are evenly coated.
Working in batches, toss the chicken pieces in the flour mixture until fully coated. Shake off the extra.
Dip the floured chicken into the egg, letting the excess drip off. Then coat the chicken in the breadcrumb mixture, pressing gently to help the crumbs stick. Place the coated nuggets to the side. Repeat this process until all the nuggets are coated.
Preheat your air fryer to 400°F. Tip: if you forget to preheat, just add 2 extra minutes to the cooking time.
Once preheated, spray the air fryer basket with cooking spray.
Arrange the nuggets in a single layer, but do not overcrowd the air fryer. Work in batches if necessary to keep the nuggets crispy.
Spray the tops of the nuggets with cooking spray and air fry at 400°F for 6–8 minutes, flipping halfway through. The nuggets are done when they're golden brown and reach an internal temperature of 165°F. Serve and enjoy!
