  • 2 tablespoons soy sauce
  • 1 tablespoon cornstarch
  • 1 tablespoon rice wine vinegar
  • 1 teaspoon sesame oil
  • 1/2 teaspoon ground ginger
  • 1/4 teaspoon garlic powder
  • 1 pound fresh or dried lo mein noodles
  • 1 tablespoon vegetable oil
  • 1 medium onion, thinly sliced
  • 2 cloves garlic, minced
  • 4 cups broccoli florets
  • 1/2 cup sliced carrots optional
  • 1/2 cup soy sauce
  • 2 tablespoons oyster sauce
  • 1 tablespoon brown sugar
  • 1 tablespoon sesame oil
  • 1 tablespoon cornstarch
  • 1/2 cup chicken broth or water
  • 1/4 teaspoon red pepper flakes optional
  • Sesame seeds for garnish
  • Chopped green onions for garnish

Equipment

  • Wok or large skillet
  • Medium bowl
  • small bowl
  • Measuring cups
  • Measuring spoons
  • knife
  • cutting board
  • Strainer or colander

Method
 

  1. Marinate the Beef: In a medium bowl, combine the sliced beef with soy sauce, cornstarch, rice wine vinegar, sesame oil, ginger, and garlic powder. Mix well and let marinate for at least 30 minutes, or up to 2 hours in the refrigerator.
  2. Cook the Noodles: Cook the lo mein noodles according to package directions, but slightly undercook them by about 1-2 minutes. Drain and set aside.
  3. Prepare the Sauce: In a small bowl, whisk together the soy sauce, oyster sauce, brown sugar, sesame oil, cornstarch, chicken broth (or water), and red pepper flakes (if using). Set aside.
  4. Stir-Fry the Beef: Heat a large wok or skillet over high heat. Add the vegetable oil. Once the oil is hot, add the marinated beef and stir-fry until browned and cooked through, about 3-5 minutes. Remove the beef from the wok and set aside.
  5. Stir-Fry the Vegetables: Add the onion and garlic to the wok and stir-fry until softened, about 2 minutes. Add the broccoli florets and carrots (if using) and stir-fry until tender-crisp, about 3-5 minutes.
  6. Combine Everything: Return the cooked beef to the wok with the vegetables. Pour in the prepared sauce and bring to a simmer, stirring constantly until the sauce thickens, about 1-2 minutes.
  7. Add the Noodles: Add the cooked lo mein noodles to the wok and toss everything together until the noodles are well coated with the sauce.
  8. Serve: Serve immediately, garnished with sesame seeds and chopped green onions.

Notes

For best results, use fresh lo mein noodles if available. If using dried noodles, be careful not to overcook them. Low-sodium soy sauce can be used to control the saltiness of the dish. Adjust the amount of red pepper flakes to your preference. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. You can substitute the flank steak or sirloin for chicken or tofu.
