Begin by bringing a large pot of water to a rolling boil. Add the lo mein noodles and cook according to package instructions, usually about 4-5 minutes until al dente. Drain and rinse under cold water to stop the cooking process. Set aside.
While the noodles are cooking, slice the chicken breast (or thigh meat) into thin strips. In a bowl, mix together 2 tablespoons of soy sauce and 1 teaspoon of minced ginger. Add the chicken to the marinade and let it sit for about 10 minutes.
Heat 1 tablespoon of wok oil in your wok or large skillet over medium-high heat. Add the marinated chicken, cooking for about 5-7 minutes until it’s cooked through and no longer pink. Remove the chicken from the pan and set aside.
In the same wok, add 3 teaspoons of minced garlic and sauté for about 30 seconds until fragrant. Then, add the sliced mushrooms, bell peppers, carrots, and onions. Stir-fry the vegetables for about 4-5 minutes until they’re tender-crisp.
Return the cooked chicken to the wok with the vegetables. In a small bowl, whisk together 2 tablespoons of soy sauce, 2 teaspoons of brown sugar, 2 teaspoons of oyster sauce, 1 teaspoon of sesame oil, 1/2 teaspoon of minced ginger, and 1 teaspoon of sriracha (if using). Pour this sauce over the chicken and vegetables.
Add the cooked lo mein noodles to the wok, tossing everything together to ensure the noodles are well-coated with the sauce and combined with the chicken and vegetables. Cook for an additional 2-3 minutes until everything is heated through.
Serve your Easy Chicken Lo Mein immediately, garnished with additional green onions or sesame seeds if desired. Enjoy your homemade deliciousness!
