Preheat your air fryer to 400°F.
Slice the chicken breast into bite-sized pieces or strips, ensuring even cooking.
In a shallow bowl, whisk together the egg white, fresh orange juice, and orange zest.
In a separate bowl, combine almond flour, garlic powder, smoked paprika, salt, and pepper.
Dip each chicken piece into the egg white mixture, then dredge evenly in the almond flour mixture, ensuring each piece is well-coated.
Arrange the coated chicken pieces in a single layer in the air fryer basket, ensuring they are not overcrowded.
Air fry for 10-12 minutes, flipping halfway through, until the chicken is cooked through and the coating is crispy and golden.
Serve immediately, garnished with extra orange zest or a squeeze of fresh orange juice if desired.
