Ingredients

Scale

For the Sauce

  • 3/4 cup low sodium soy sauce
  • 1/2 cup oyster sauce
  • 1/2 cup honey (or substitute with brown sugar)
  • 2 tablespoons rice vinegar
  • 1 tablespoon browning (optional, for color)

For the Steak

  • 1 pound flank steak or sirloin, sliced thinly
  • 3 tablespoons soy sauce
  • 1 tablespoon cornstarch
  • 1 tablespoon rice wine vinegar
  • 1 teaspoon ground ginger

For the Stir Fry

  • 2 tablespoons sesame oil
  • 1/4 cup diced onions
  • 1/8 cup diced garlic
  • 1/8 cup diced ginger
  • 16 ounces broccoli florets
  • 16 ounces noodles (spaghetti can be used as a substitute)

For the Cornstarch Slurry

  • 2 tablespoons cornstarch
  • 2 tablespoons water

Instructions

  1. Prepare the Sauce: In a bowl, whisk together low sodium soy sauce, oyster sauce, honey, rice vinegar, and optional browning until fully combined. Set aside.
  2. Marinate the Steak: In another bowl, combine the sliced steak with soy sauce, cornstarch, rice wine vinegar, and ground ginger. Mix well to coat the meat evenly. Let it marinate for at least 15-20 minutes for better flavor absorption.
  3. Cook the Noodles: Boil water in a large pot and cook the noodles according to package instructions until al dente. Drain and set aside.
  4. Stir Fry Aromatics: Heat the sesame oil in a large skillet or wok over medium-high heat. Add diced onions, garlic, and ginger and stir-fry until fragrant and soft, about 2 minutes.
  5. Cook the Steak: Add the marinated steak slices to the skillet and stir-fry for 3-4 minutes until the beef is browned and cooked to your desired doneness.
  6. Add Broccoli: Toss in the broccoli florets and continue to stir-fry for another 3-4 minutes until the broccoli is tender-crisp.
  7. Add Sauce and Thicken: Pour the prepared sauce over the beef and broccoli. In a small bowl, mix the cornstarch slurry by combining cornstarch and water, then add it to the skillet. Stir continuously until the sauce thickens and coats all the ingredients well.
  8. Toss Noodles: Add the cooked noodles to the skillet and toss everything together to evenly distribute the sauce throughout.
  9. Serve: Remove from heat and serve the Beef and Broccoli Lo Mein hot. Garnish with sesame seeds or chopped green onions if desired.

Notes

  • If you prefer a vegetarian version, substitute the beef with tofu or mushrooms and use vegetarian oyster sauce or skip it.
  • Using flank steak or sirloin ensures tender strips, but you can also use other quick-cooking cuts.
  • If you do not have browning, it can be omitted without affecting the flavor significantly.
  • Spaghetti noodles are a convenient substitute for lo mein noodles when unavailable.
  • Adjust the amount of honey or brown sugar to taste for sweeter or less sweet sauce.
  • Ensure to stir the cornstarch slurry continuously when adding to avoid lumps in the sauce.
