Cut the chicken into bite-sized pieces and place in a bowl. Add soy sauce, honey, and chili paste. Mix well and let it marinate while you prepare the other ingredients. This step ensures the chicken is flavorful inside and out.
Bring a pot of salted water to a boil and cook the noodles according to package instructions. Once cooked, drain and set aside. I like tossing them with a small drizzle of oil to prevent sticking.
Whisk together peanut butter, brown sugar, soy sauce, sesame oil, rice vinegar, and chili paste. This mixture creates the signature sweet, salty, and slightly spicy Kung Pao flavor. Set aside until ready to combine with the noodles.
Heat oil in a skillet over medium heat. Add sliced green onions and garlic, cooking until fragrant. This step releases the aromatic flavors that make the dish irresistible.
Add marinated chicken to the skillet and cook each side for 2–3 minutes until golden and fully cooked. Make sure the internal temperature reaches 165°F for safe consumption.
Add the cooked noodles and sauce to the skillet. Toss until everything is coated evenly. Finally, sprinkle crushed peanuts on top and garnish with extra green onions for a fresh finish.
