1. Prepare the Beef:
- Slice and Marinate the Beef:
- Thinly slice the beef flank steak against the grain to ensure tenderness. In a bowl, combine the sliced beef with soy sauce, oyster sauce, cornstarch, and sesame oil. Mix well to coat the beef evenly. Let it marinate for at least 15 minutes while you prepare the other ingredients.
2. Prepare the Lo Mein Sauce:
- Mix the Sauce:
- In a small bowl, whisk together the soy sauce, oyster sauce, hoisin sauce, dark soy sauce (if using), Shaoxing wine or dry sherry, sugar, and beef broth or water. Set the sauce aside.
3. Cook the Noodles:
- Boil the Noodles:
- Cook the lo mein noodles or spaghetti according to the package instructions until al dente. Drain the noodles, rinse them under cold water to stop the cooking process, and toss them with a little sesame oil to prevent sticking. Set the noodles aside.
4. Stir-Fry the Beef and Vegetables:
- Heat the Oil:
- Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat until it’s shimmering.
- Cook the Beef:
- Add the marinated beef to the wok in a single layer. Stir-fry for 2-3 minutes until the beef is browned and cooked through. Remove the beef from the wok and set it aside.
- Stir-Fry the Vegetables:
- In the same wok, add another tablespoon of vegetable oil if needed. Add the minced garlic and ginger, and stir-fry for about 30 seconds until fragrant. Add the sliced onion, bell pepper, carrot, snow peas, and shiitake mushrooms (if using). Stir-fry the vegetables for 3-4 minutes until they are tender-crisp.
5. Combine Everything:
- Add the Beef and Noodles:
- Return the cooked beef to the wok, along with the cooked noodles. Pour the prepared Lo Mein sauce over the top.
- Toss and Heat Through:
- Toss everything together using tongs or a spatula, ensuring the noodles and vegetables are well-coated in the sauce. Stir-fry for an additional 2-3 minutes until everything is heated through and the sauce has thickened slightly.
6. Serve:
- Garnish and Serve:
- Transfer the Beef Lo Mein to a serving platter or individual bowls. Garnish with chopped green onions and sesame seeds if desired. Serve hot.
