Follow these simple steps to create your delicious Baked Orange Chicken:

1. Preheat your oven to 400°F (200°C). Prepare a baking dish by greasing it lightly.
2. Prepare the Marinade: In a mixing bowl, whisk together the orange juice, orange zest, soy sauce, rice vinegar, honey (or maple syrup), cornstarch, minced garlic, and ginger.
3. Marinate the Chicken: Place the chopped chicken in the marinade, ensuring it is well-coated. Cover and chill in the refrigerator for at least 30 minutes.
4. Transfer Chicken to Baking Dish: After marinating, arrange the chicken pieces in a single layer in your prepared baking dish.
5. Drizzle with Olive Oil: Lightly drizzle olive oil over the chicken to keep it moist during baking.
6. Bake the Chicken: Place the dish in the preheated oven and bake for 25-30 minutes until the chicken is cooked through and golden brown. Stir halfway to ensure even cooking.
7. Baste with Sauce: For extra flavor, baste the chicken with the pan juices halfway through the baking time.
8. Check for Doneness: Use a meat thermometer to ensure that the chicken reaches an internal temperature of 165°F (75°C).
9. Garnish: Once cooked, remove from the oven and sprinkle green onions and sesame seeds on top, if desired.

These steps are designed to lead you through the cooking process effortlessly, allowing you to enjoy a delightful meal with minimal fuss.
