Preheat your air fryer to 400ºF (204ºC) for 5 minutes.
Prepare the breading station. Mix the gluten-free breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, paprika, salt, and black pepper in a shallow dish. Set it aside. In another shallow dish, crack and beat eggs.
Dip the chicken nuggets into the beaten eggs, allowing any excess to drip off.
Coat the chicken pieces with the breadcrumb mixture, pressing gently to adhere the crumbs to the chicken.
Place the breaded chicken nuggets in a single layer in the air fryer basket. You may need to do this in batches, depending on the size of your air fryer.
Spray the chicken nuggets with avocado oil to promote browning.
Air fry the chicken nuggets at 400ºF (204ºC) for 5 minutes. Then, open the air fryer and flip all the chicken to ensure even cooking.
Continue air frying for 5 - 7 minutes or until the chicken nuggets are cooked through and golden brown.
Carefully remove the chicken nuggets from the air fryer and let them cool slightly before serving.
Serve your air fried gluten-free chicken nuggets with your favorite dipping sauce, and enjoy!
