  • 8 oz lo mein noodles or spaghetti
  • 8 oz flank steak or another cut (see note), sliced 1/4" thick against the grain
  • 1 tbsp soy sauce light
  • 1 tbsp cornstarch
  • 1 tbsp vegetable oil
  • 1 tbsp garlic minced
  • 1 medium carrot cut into matchsticks
  • 3 cups broccoli florets
  • 1 tbsp sesame seeds optional garnish



  • Prepare the noodles according to the package directions (see note).
  • Cut flank steak into thin strips, about 2 x 1/4 inch each (5 cm x 1/2 cm).
  • In a medium bowl, mix 1 tbsp of cornstarch and 1 tbsp of soy sauce.
  • Toss the beef strips in the soy sauce mixture and marinate for 10 minutes to tenderize (you can skip this step if in a rush).
  • In a medium bowl, mix 2 tbsp soy sauce, hoisin sauce, sugar and ginger. Reserve.
  • Place a large skillet or wok over medium-high heat and add vegetable oil.
  • When the oil is hot, add the beef strips and stir fry for 2-3 minutes until the beef is no longer pink.
  • Add the minced garlic, sliced carrots and broccoli. Stir fry for 5 minutes or until vegetables are tender.
  • Add lo mein to the beef/vegetable mixture and toss with the reserved lo mein sauce and sesame oil.
  • Garnish with optional sesame seeds and serve immediately.



  • Cuts such as flank steak, sirloin, rib eye work well. You may want to freeze the meat for 30 minutes first to make it easier to cut into uniform strips.
  • Use a quality light soy sauce such as Kikkoman, San-J or Pearl River Bridge. For added flavor, mix 1 tbsp light soy sauce with 1 tbsp dark soy sauce.
  • Dried lo mein noodles should be boiled, while refrigerated noodles can just be warmed in hot water.
