Prepare the Chicken:
Preheat the air fryer to 400°F (200°C).
In a bowl, whisk together the flour, cornstarch, garlic powder, onion powder, paprika, salt, and pepper.
Dip each chicken piece into the flour mixture, then into the beaten eggs, and finally coat with panko breadcrumbs. Press the breadcrumbs onto the chicken to ensure they stick.
Air Fry the Chicken:
Lightly spray the air fryer basket with cooking spray to prevent sticking. Arrange the chicken pieces in a single layer, making sure they are not touching. You may need to cook the chicken in batches depending on the size of your air fryer.
Air fry the chicken for 8-10 minutes, flipping halfway through, until golden brown and crispy.
Make the Bang Bang Sauce:
While the chicken is cooking, combine the mayonnaise, sweet chili sauce, sriracha, rice vinegar, garlic powder, and a pinch of salt in a small bowl. Stir until smooth and creamy. Adjust the spice level by adding more sriracha if desired.
Toss the Chicken in the Sauce:
Once the chicken is cooked, transfer it to a large bowl. Pour the Bang Bang sauce over the chicken and toss gently until all the pieces are coated.
Serve:
Serve the crispy Bang Bang chicken over rice, with a side of veggies, or as an appetizer with extra sauce on the side for dipping.
