In a bowl, mix gluten-free flour, salt, and pepper. In another bowl, beat the eggs. In a third bowl, place cornstarch. Dip the chicken pieces into the flour mixture, then into the eggs, and finally coat them with cornstarch to create a crispy outer layer.
In a large skillet or wok, heat oil over medium-high heat. Once hot, carefully add the coated chicken pieces. Fry in batches to avoid overcrowding, cooking until golden brown and cooked through (about 5-7 minutes). Remove and drain on paper towels.
In a separate saucepan over medium heat, combine orange juice, orange zest, honey, gluten-free soy sauce, rice vinegar, ginger, and garlic. Stir well and simmer for about 5-7 minutes, until slightly thickened.
Once the sauce thickens, add the fried chicken pieces into the saucepan. Toss gently to coat the chicken evenly with the orange sauce.
Transfer the Orange Chicken to a serving platter. Garnish with sliced green onions for freshness and an added pop of color.
Notes
For best results, use freshly squeezed orange juice.
