Cut the chicken breast into bite-sized pieces. Pat dry with a paper towel.
In a bowl, whisk the egg white until slightly frothy. In a separate shallow dish, place the almond flour.
Lightly coat each chicken piece in the egg white, then dredge in almond flour, shaking off any excess.
Preheat the air fryer to 400°F. Lightly spray or brush the basket with a small amount of oil.
Place the coated chicken pieces in the air fryer basket in a single layer. Air fry for about 10-12 minutes, flipping halfway through for even crispiness.
While the chicken cooks, combine orange juice, soy sauce, honey, grated ginger, minced garlic, and cornstarch in a small saucepan. Simmer over medium heat, stirring frequently until the sauce thickens slightly, about 3-5 minutes.
Once the chicken is crispy and cooked through, transfer to a serving bowl and drizzle with the warm orange sauce.
Serve immediately and enjoy a light, flavorful dish with a perfect balance of protein, tang, and a satisfying crunch.
