Preparing Chinese Orange Chicken is straightforward and can be done in just a few easy steps. Follow this guide to create a delicious meal:

1. Prep the Chicken: Start by cutting the chicken thighs into bite-sized pieces. Set aside.
2. Mix Dry Ingredients: In a bowl, combine the flour, cornstarch, salt, black pepper, garlic powder, and onion powder. Stir well.
3. Coat the Chicken: Dip each piece of chicken into the beaten egg, then dredge it in the flour mixture until fully coated. Shake off any excess.
4. Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat until shimmering.
5. Fry the Chicken: Carefully add the coated chicken pieces to the hot oil in batches. Fry for about 5-7 minutes or until golden brown and cooked through. Remove and place on a paper towel-lined plate to drain excess oil.
6. Prepare the Orange Sauce: In a separate saucepan, combine the orange juice, granulated sugar, soy sauce, rice vinegar, grated ginger, and sesame oil. Bring to a simmer over medium heat.
7. Thicken the Sauce: Stir in the cornstarch mixture and continue cooking until the sauce thickens, about 1-2 minutes. If using, add red pepper flakes for some heat.
8. Coat the Chicken: In a large bowl, toss the fried chicken pieces with the orange sauce until fully coated.
9. Add Zest: Finally, sprinkle the orange zest over the chicken for an aromatic finish.
10. Serve: Transfer the coated chicken to a serving platter or bowl, ready for enjoyment.
