Preheat your air fryer to 400°F.
Cut the chicken breast into bite-sized pieces.
Zest the orange and then juice it; reserve both the zest and juice separately.
In a bowl, combine the chicken pieces with a pinch of salt, pepper, garlic powder, ginger powder, and half of the orange juice. Allow marinating for 10-15 minutes.
Add the cornstarch to the marinated chicken and toss until the pieces are evenly coated.
Lightly spray or drizzle the olive oil over the chicken pieces.
Place the chicken in the air fryer basket in a single layer. Air fry for 10-12 minutes, shaking the basket halfway through for even crispiness.
While the chicken cooks, heat the remaining orange juice with the orange zest in a small saucepan over medium heat. Let it simmer for 3-4 minutes until slightly reduced to form a glaze.
Once the chicken is cooked and crispy, transfer it to a serving bowl and drizzle the warm orange glaze over the chicken.
Serve immediately and enjoy your crispy, tangy, and flavorful air-fried orange chicken.
