Ingredients

Scale

Sauce

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

Steak Marinade

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

Stir Fry

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

Cornstarch Slurry

  • 2 tablespoons cornstarch
  • 2 tablespoons water

Instructions

  1. Prepare the Sauce: In a bowl, combine low sodium soy sauce, oyster sauce, honey (or brown sugar), rice vinegar, and optional browning. Mix thoroughly until well combined and set aside.
  2. Marinate the Steak: In a separate bowl, add sliced steak along with soy sauce, cornstarch, rice wine vinegar, and ground ginger. Mix until all steak pieces are evenly coated. Allow to marinate for at least 15 minutes to enhance flavor and tenderness.
  3. Cook the Noodles: Boil noodles according to package instructions until al dente. Drain and set aside, tossing with a bit of oil to prevent sticking if desired.
  4. Prepare the Stir Fry Ingredients: Dice onions, garlic, and ginger. Cut broccoli into florets if not pre-cut.
  5. Start Stir Frying: Heat sesame oil in a large skillet or wok over medium-high heat. Add diced onions, garlic, and ginger; stir-fry for 1-2 minutes until aromatic.
  6. Cook the Steak: Add the marinated steak to the skillet. Stir-fry for 3-4 minutes until the steak is browned and cooked through.
  7. Add Broccoli: Toss broccoli florets into the skillet. Stir-fry for 3-5 minutes, or until broccoli is tender-crisp.
  8. Add Sauce and Cornstarch Slurry: Pour the prepared sauce over the stir fry. Mix cornstarch with water to create a slurry, then add it to the skillet. Stir continuously until the sauce thickens and coats the ingredients evenly.
  9. Combine with Noodles: Add cooked noodles to the skillet. Toss everything together to combine and heat through for 1-2 minutes.
  10. Serve: Remove from heat and serve the beef and broccoli lo mein noodles hot, garnished with optional sesame seeds or green onions if preferred.

Notes

  • Flank steak or sirloin work best due to their tenderness and flavor.
  • If you prefer vegetarian, substitute beef with tofu and oyster sauce with mushroom sauce.
  • Using spaghetti noodles is a convenient substitute if lo mein noodles are unavailable.
  • Adjust honey or brown sugar quantity for desired sweetness.
  • Marinating the steak longer (up to 1 hour) can enhance tenderness.
  • Optional browning sauce is mostly for color, can be skipped without impacting taste.
