Preheat your air fryer to 400°F.
Cut the chicken breast into bite-sized pieces.
In a bowl, mix the egg white and low-sodium soy sauce. Add the chicken pieces and let them marinate for 10 minutes.
In another bowl, combine panko breadcrumbs with garlic powder, ground ginger, and the finely grated zest of the orange.
Dip each piece of marinated chicken into the breadcrumb mixture, ensuring an even coat.
Place the coated chicken pieces in the air fryer basket in a single layer. Lightly spray with cooking spray if desired.
Air fry for 10-12 minutes, shaking the basket halfway through, until the chicken is golden and crispy.
While the chicken is cooking, squeeze the juice from the orange into a small saucepan. Add a dash of low-sodium soy sauce and, if a thicker glaze is desired, stir in the cornstarch dissolved in a teaspoon of water.
Bring the orange mixture to a simmer over medium heat until slightly thickened, then remove from heat.
Toss the air-fried chicken in the warm orange glaze or drizzle the glaze over the crispy chicken when serving.
Serve immediately and enjoy your crispy, tangy, and flavorful meal.
