Combine breading ingredients in a bowl. Set aside. Beat egg in a small bowl and set aside.
Combine all chicken mixture ingredients in a bowl and mix (use your hands!) until fully incorporated and smooth. Form into 24 nuggets by making them into little balls (roughly 1 tbsp each) and then flattening them out a bit to get that classic nugget shape.
Dunk each nugget in the egg mixture, then in the breading, and place on a well sprayed air fryer tray or basket.
Spray well with cooking spray and air fry at 375 for 10-12 minutes, until fully cooked and an internal thermometer reads 165F+.
Serve with your favorite dipping sauce and enjoy!
Store leftovers in an airtight container in the fridge for up to 4 days and reheat in the air fryer (350F for 4-5 minutes).
