Preheat your air fryer to 400°F.
Slice the chicken breast into strips or bite-sized pieces for quicker, even cooking.
In a shallow bowl, whisk the egg until well combined.
Season the chicken pieces with salt and pepper.
Dredge the chicken first in the egg, then coat it evenly with panko breadcrumbs. Lightly spray or drizzle with olive oil to help achieve a crispy texture.
Place the chicken in the air fryer basket in a single layer. Air fry for about 10-12 minutes, flipping halfway through, until the chicken is cooked through and the coating is golden and crispy.
While the chicken cooks, prepare the orange sauce. In a small saucepan, combine orange juice, orange zest, minced garlic, and grated ginger. Simmer over medium heat for 3-4 minutes until slightly thickened. Adjust seasoning with a pinch of salt and pepper if desired.
Once the chicken is done, transfer to a serving dish. Drizzle the warm orange sauce over the crispy chicken or serve it on the side for dipping.
Enjoy your flavorful, crispy air-fried orange chicken as a satisfying meal any time of day!
