1In a large bowl, mix together flour, celery seeds, pepper, garlic powder, ginger, salt, paprika, thyme, basil, oregano, and seasoned salt.
2In another bowl, beat the egg with buttermilk. Add chicken pieces and turn to coat completely. Let marinate for 20 minutes.
3Remove each piece from buttermilk mixture, dredge well in seasoned flour, then place on a parchment-lined tray. Let rest for 15 minutes to set the crust.
4Preheat air fryer to 193°C (380°F) for 5 minutes. Spray the basket with nonstick spray. Place chicken pieces in a single layer, then spray with olive oil.
5Cook for 4 minutes, flip each piece, spray again with oil, and cook another 4 minutes. Time may vary depending on thickness.
6Check internal temperature – it should reach 74°C (165°F) in the thickest part. Remove from air fryer and serve immediately.
