Marinating the Chicken: In a bowl, combine chicken cubes with crushed garlic, soy sauce, a beaten egg, and pepper to taste. Allow the chicken to marinate for at least 30 minutes to let the flavors infuse.
Preparing the Chicken for Baking: Preheat the oven to 400°F (200°C). Lightly coat a baking tray with cooking spray and dust it with a thin layer of all-purpose flour. Dredge each marinated chicken piece in flour, shaking off any excess, and place them on the prepared baking tray.
Baking the Chicken: Bake in the preheated oven for 20-25 minutes or until the chicken is golden brown and cooked through. Ensure to flip the chicken pieces halfway through the baking time for even crispiness.
Making the Orange Sauce: While the chicken is baking, prepare the orange sauce. In a saucepan, combine fresh orange juice, cornstarch, rice vinegar or lime juice, and Stevia. Bring the mixture to a simmer over medium heat, stirring continuously until it thickens.
Coating the Baked Chicken: Once the chicken is done baking, transfer it to a pan. Pour the prepared orange sauce over the chicken and toss until each piece is coated evenly. Cook for an additional 2-3 minutes to let the flavors meld. Serve the healthier Asian-style Orange Chicken over a bed of steamed rice or with your favorite vegetables. Garnish with chopped green onions or sesame seeds for added flavor.
