Pat the chicken breast dry and season lightly with salt, pepper, garlic powder, and ginger powder.
Whisk the egg white in a shallow bowl. In a separate dish, combine almond flour with a pinch of salt and pepper.
Dip each piece of chicken first in the egg white, then dredge thoroughly in the seasoned almond flour.
Preheat your air fryer to 400°F. Arrange the coated chicken pieces in a single layer, ensuring they are not touching.
Air fry the chicken for about 12-15 minutes, flipping halfway through, until the exterior is crispy and the internal temperature reaches 165°F.
Meanwhile, in a small saucepan over medium heat, combine the orange juice and orange zest. In a small cup, mix the cornstarch with a splash of water to form a slurry, then stir it into the saucepan.
Allow the sauce to simmer for about 3-4 minutes until it thickens, stirring continuously.
Once the chicken is done, drizzle the orange sauce over the crispy pieces or serve it on the side for dipping.
Plate immediately and enjoy your crispy, tangy air-fried orange chicken.
