Beef lo mein has soft, silky noodles tossed with tender strips of beef, carrots, bell pepper, snow peas and scallions in a savory sauce. Lo mein means “tossed noodles” in Cantonese, unlike chow mein, where the noodles are crisped.
Timing and Heat
Slice the beef thin against the grain and marinate it in soy sauce, cornstarch and sesame oil. Get the wok very hot, sear the beef in batches and set it aside, then stir-fry the vegetables quickly so they keep some crunch. Add the cooked noodles, sauce and beef and toss until coated. Dried linguine or spaghetti work if you can’t find lo mein noodles.
Kosher Notes
This is a meat (fleishig) recipe. Regular oyster sauce is made from oysters and isn’t kosher; use a certified kosher oyster-flavored sauce, which is made from mushrooms. Flank steak is rarely sold kosher outside Israel, so use skirt steak or thinly sliced rib eye.
Leftovers
Leftovers keep for 3 days; reheat in a hot pan with a splash of water.

Method
- Slice the skirt steak against the grain into thin strips, about 1/4 inch thick. Place in a bowl and toss with soy sauce, cornstarch, and sesame oil. Let marinate while you prep everything else.
- In a small bowl, whisk together all sauce ingredients until smooth. Set aside.
- Bring a large pot of water to boil. Cook the lo mein noodles according to package directions until just tender. Drain and set aside. If using dried pasta, cook 1 minute less than package directions since it will cook more in the wok.
- Heat 1 tablespoon oil in a large wok or skillet over high heat. When smoking hot, add the marinated beef and stir fry for 2-3 minutes until just cooked through. Remove beef to a plate.
- Add remaining 2 tablespoons oil to the same pan. Add garlic and ginger, stir fry for 30 seconds until fragrant.
- Add carrots and bell pepper to the pan. Stir fry for 2 minutes until slightly softened but still crisp.
- Add snow peas and stir fry for another minute.
- Return the beef to the pan along with the cooked noodles. Pour the sauce over everything and toss quickly to coat, about 1-2 minutes. The noodles should absorb most of the sauce.
- Remove from heat and add the scallions. Toss once more and serve immediately, garnished with sesame seeds.
