Preheat your air fryer to 400°F.
Slice the chicken breast into bite-sized pieces.
In a shallow bowl, lightly beat the egg white.
In another bowl, combine the almond flour, orange zest, salt, and pepper.
Dip each chicken piece first into the egg white, then dredge in the almond flour mixture until evenly coated.
Place the coated chicken pieces in the air fryer basket in a single layer and spray lightly with oil if desired.
Air fry the chicken for about 10-12 minutes, flipping halfway through until golden and crispy.
While the chicken cooks, prepare the orange glaze: In a small saucepan, combine the fresh orange juice, minced garlic, and grated ginger. Simmer over medium heat for 3-4 minutes until slightly thickened.
Once the chicken is done, toss the pieces in the warm orange glaze to coat evenly.
Plate the glazed chicken with a serving of steamed broccoli on the side.
Serve immediately and enjoy your flavorful, crispy orange chicken dish.
