How to Make Beef Lo Mein
Marinate the beef with cornstarch, shaoxing wine, and salt for 15 minutes to tenderize and season.

Prep the onion and scallions. Whisk the sauce ingredients together and set aside.

Cook the noodles until just shy of al dente, then drain. Heat oil in a hot pan, sear the beef for about 2 minutes, then remove. Sauté the onion and scallion whites for 2 minutes.
Return the beef to the pan with the noodles and pour in the sauce. Toss everything until well coated and heated through.

Stir in the scallion greens, toss once more, and remove from heat. Serve immediately for best texture and flavor.
Tips and Variations
Fresh lo mein noodles give the best texture; spaghetti is a fine substitute. Don’t skip marinating the beef—that step makes a big difference. For more complexity, add a splash of oyster sauce or finish with chili oil to taste.
Why This Recipe Works Anytime
Beef Lo Mein is versatile: swap beef for chicken, shrimp, or tofu, and add vegetables like bell peppers, carrots, or bok choy. Use only light soy for a milder flavor. It’s a flexible, satisfying dish you can adapt to what’s on hand.
