Spicy kung pao chicken with peanuts is served over steamed rice for a complete, satisfying family meal. High in protein and packed with bold Sichuan flavors, this dish never disappoints.
Cut the chicken breast into bite-sized cubes and toss with 1 tablespoon soy sauce and the cornstarch. Let sit for 10 minutes.
Heat a large skillet or wok over medium-high heat. Add the sesame oil, then toast Sichuan peppercorns and dried red chilies for about 1 minute, stirring to avoid burning.
Add the marinated chicken to the pan, spreading it out in a single layer. Stir-fry for 3–4 minutes until no longer pink.
Add chopped bell pepper, zucchini, garlic, and ginger; stir-fry for 2 more minutes, maintaining high heat to prevent steaming.
Pour in the remaining soy sauce, rice vinegar, and sugar. Toss in the roasted peanuts and sliced green onions. Stir-fry for another 2 minutes to glaze everything and blend flavors.
Serve the kung pao chicken hot over bowls of steamed white rice.
