Set Air Fryer to 400 degrees Fahrenheit. Coat chicken thighs with potato starch making sure all pieces are fully covered. Use tongs to place chicken pieces in Air Fryer basket. Cook chicken pieces for 20-25 minutes until crispy, shaking basket every 5 minutes.
Meanwhile, prepare sauce by heating vegetable oil in skillet over medium-high heat. Once hot, add green onions, dried chilies, garlic, and ginger and stir fry for about 1 minute, until chillies brighten in color and onions have softened.
Add brown sugar, chicken broth, soy sauce, rice vinegar, sesame oil, and pinch of salt to the skillet and stir. Bring to a boil and cook for about 3 minutes.
Once chicken in air fryer is finished, add to sauce and stir in.
Create a thickener by whisking 2 teaspoons of corn starch in 1/4 cup cold water. Stir into boiling sauce and allow to cook for about 1 minute, until sauce has thickened.
Serve with rice and vegetable and Enjoy :)
