1 1/2 pounds boneless, skinless chicken breasts, cut into 1-inch chunks
1 cup plus 2 tablespoons cornstarch, divided
2 large eggs, beaten
1 cup vegetable oil
1/2 teaspoon sesame seeds
1 green onion, thinly sliced
1 cup chicken broth
1/2 cup freshly squeezed orange juice
1/2 cup sugar
1/3 cup distilled white vinegar
1/4 cup soy sauce
2 cloves garlic, minced
1 tablespoon orange zest
1 teaspoon Sriracha, or more, to taste
1/4 teaspoon ground ginger
1/4 teaspoon white pepper
- Marinade: whisk together chicken broth, orange juice, sugar, vinegar, soy sauce, garlic, orange zest, Sriracha, ginger and white pepper in a large bowl.
- In a gallon-size Ziploc bag, combine chicken and 2/3 cup of the marinade. Marinate for at least 30 minutes, turning the bag occasionally. Drain the chicken from the marinade; discard the marinade.
- Heat remaining marinade in a medium saucepan over medium heat. Bring to a boil and stir in 2 tablespoons cornstarch combined with 2 tablespoons water. Cook, stirring frequently, until thickened about 1-2 minutes; keep warm.
- Working one piece at a time, dip the chicken into the eggs then dredge in remaining 1 cup cornstarch, pressing to coat.
- Heat vegetable oil in a large saucepan. Working in batches, add the chicken and dry until golden brown and cooked through, about 1-2 minutes. Transfer to a plate lined with a paper towel to drain. Discard excess oil.
- Toss chicken with the marinade, garnish with sesame seeds and green onion, if desired. Serve immediately.
