Prepare the Chicken:
Cut the chicken into equal sized, I prefer using cubed chicken.
Toss chicken pieces in salt and half the cornstarch in medium bowl, mix until well coated.
In a shallow bowl, prepare the egg mixture, Use tongs to dip the chicken in the then dredge in remaining cornstarch.
Line your air fryer with baking sheet to prevent stitcking.
Preheat the air fryer to 400°F. Once heated, arrange chicken in a single layer in the air fryer basket and cook at 350 degrees for 8-10 minutes, turning halfway through until golden brown.
Make the Orange Sauce:
In a small saucepan over medium heat, combine orange juice, brown sugar, honey, vinegar, soy sauce, ginger, garlic, and red pepper flakes; simmer for 3 minutes.
Whisk together the remaining cornstarch and cold water to make cornstarch slurry; stir into the sauce and continue to cook until thickened, about 5 minutes. Remove from heat and stir in orange zest.
Combine and Serve:
Toss the cooked chicken with the orange sauce, coating thoroughly. Reserve some sauce for drizzling over rice if desired.
Garnish with sliced green onions and sesame seeds.
