This chicken lo mein is a fast, flavor-packed noodle stir-fry with tender chicken, crisp vegetables, and a glossy savory sauce. It comes together in minutes, making it a reliable weeknight dinner that tastes better than takeout.
Make the sauce: In a small bowl, whisk the cornstarch and dark soy sauce until smooth and lump-free. Stir in the soy sauce, Chinese cooking wine or mirin, sugar, sesame oil, white pepper, and water.
Season the chicken: Place the chicken in a bowl and toss with 2 teaspoons of the prepared sauce. Set aside while you prepare the wok.
Heat the oil in a wok or large heavy skillet over high heat until very hot and just starting to smoke.
Add the onion and garlic. Stir-fry for about 30 seconds, just until fragrant.
Add the chicken and stir-fry for 1 minute, until the outside turns opaque but the center is not fully cooked.
Add the carrots and bell pepper. Stir-fry for 2 minutes, or until the vegetables are slightly tender and the chicken is cooked through.
Add the noodles and the remaining sauce. Toss continuously with tongs or two wooden spoons for about 30 seconds to coat the noodles evenly.
Add the green onions and continue tossing for 1 minute, until the sauce thickens slightly and the noodles are glossy.
Serve immediately while hot, with extra sliced green onions on top if desired.
If using dried noodles, cook them just until al dente before stir-frying so they do not turn mushy. Chicken thighs, shrimp, tofu, or beef all work well here. Store leftovers in an airtight container in the refrigerator for up to 2 days and reheat quickly in a hot pan with a splash of water.
