Preheat the air fryer to 400°F.
Slice the chicken breast into bite-sized strips or pieces.
In a shallow bowl, whisk the egg white until frothy.
In another bowl, combine the panko breadcrumbs and cornstarch.
Dip the chicken pieces first into the egg white, then dredge them in the breadcrumb mixture, ensuring each piece is evenly coated.
Lightly spray the air fryer basket with cooking oil spray. Arrange the chicken pieces in a single layer, ensuring there is space between each piece.
Air fry the chicken for about 10-12 minutes, flipping halfway through, until the coating is golden and crispy and the chicken is fully cooked.
While the chicken is cooking, prepare the orange glaze. In a small saucepan over medium heat, combine the fresh orange juice, low-sodium soy sauce, minced garlic, and grated ginger.
Let the sauce simmer for 3-4 minutes until it slightly thickens, stirring occasionally.
Once the chicken is crispy, toss it in the warm orange glaze until evenly coated.
Serve immediately and enjoy this tangy, crispy twist on classic orange chicken.
