Cut the chicken breasts into 1 inch cubes. Set out three bowls. Bowl 1: Combine the powdered ranch dressing mix and gluten free baking mix. Bowl 2: Mix the oil and milk together, whisk well. Bowl 3: Place the gluten free bread crumbs in the third bowl.
Preheat the air fryer to 400 degrees F.
Work in two batches. Dip half the chicken pieces in the gluten free baking mix. Then dunk them in the oil and milk mixture. Finally dip the pieces in the gluten free bread crumbs.
Lay the chicken nuggets in a single layer in the air fryer basket. Cook for 7 minutes.
Remove from the basket and repeat with the remaining chicken pieces.
All air fryers vary a little. The nuggets may need anywhere from 6-9 minutes cook time per batch. Love Gluten? You can make this exact recipe using regular wheat flour and bread crumbs.
