1. Marinate the Beef:
- In a bowl, combine the thinly sliced beef with 1 tablespoon soy sauce and cornstarch. Let it marinate for at least 15 minutes.
2. Prepare the Sauce:
- In another bowl, whisk together 2 tablespoons soy sauce, oyster sauce, hoisin sauce, sesame oil, sugar, ground ginger, minced garlic, and beef broth. Set aside.
3. Cook the Noodles:
- Cook the lo mein noodles or spaghetti according to the package instructions until just tender. Drain and set aside.
4. Stir-Fry the Beef:
- Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Add the marinated beef and stir-fry until browned and cooked through, about 2-3 minutes. Remove the beef from the skillet and set aside.
5. Stir-Fry the Vegetables:
- In the same skillet, add the remaining tablespoon of vegetable oil. Add the bell peppers, broccoli, carrots, and snow peas. Stir-fry for about 2-3 minutes, or until the vegetables are just tender but still crisp.
6. Combine Everything:
- Return the cooked beef to the skillet with the vegetables. Add the cooked noodles and the prepared sauce. Toss everything together over medium-high heat until well combined and the noodles are heated through, about 2 minutes.
7. Serve:
- Transfer the Beef Lo Mein to serving dishes. Garnish with sliced green onions and sesame seeds if desired. Serve hot.
Tips:
- Noodle Choice: While lo mein noodles are traditional, you can use any type of noodle you have on hand, including spaghetti or linguine, for a similar result.
- Vegetable Variations: Feel free to use any vegetables you like or have on hand. Mushrooms, cabbage, and bean sprouts are also great additions to Lo Mein.
- Slicing the Beef: For tender beef, make sure to slice it thinly against the grain. This cuts through the muscle fibers and makes the beef more tender when cooked.
Enjoy your homemade Beef Lo Mein, a flavorful and satisfying dish that’s sure to become a weeknight favorite!
