Ingredients

For the Beef Lo Mein

• 400 g (14 oz) fresh lo mein noodles, or cooked egg noodles
• 250 g (9 oz) beef sirloin, tenderloin, rump, or another tender cut
• 3–4 mushrooms, sliced
• 2–3 spring onions, cut into 2-inch pieces
• 1 bell pepper, julienned
• 2–3 cabbage leaves, thinly sliced
• 5–6 snow peas
• 1 small carrot, julienned
• 2 tablespoons vegetable oil

Sauce Mix

• 2 tablespoons light soy sauce
• 1 tablespoon sesame oil
• 2 teaspoons dark soy sauce
• 4 tablespoons oyster sauce
• 1 tablespoon sugar
• 1 tablespoon Shaoxing wine, or water or rice vinegar
• ¼ teaspoon white pepper

Beef Marinade

• 1 tablespoon Sauce Mix
• 1 teaspoon cornstarch
• ¼ teaspoon baking soda

Step-by-Step Instructions

1. Prepare the beef

Slice the beef thinly against the grain. Thin slices will cook quickly and stay tender.

Place the beef in a bowl and add 1 tablespoon of the prepared Sauce Mix, cornstarch, and baking soda.

Mix thoroughly until the beef is evenly coated. Let it marinate for about 10–15 minutes while you prepare the remaining ingredients.

2. Prepare the sauce

In a small bowl, combine the light soy sauce, sesame oil, dark soy sauce, oyster sauce, sugar, Shaoxing wine, and white pepper.

Stir well until the sugar is incorporated. Set aside.

3. Prepare the noodles

If using fresh lo mein noodles, prepare them according to the package directions.

If using cooked egg noodles, have them ready before you start stir-frying.

Drain the noodles thoroughly. Avoid overcooking them because they will be added to the wok later.

4. Prepare the vegetables

Slice the mushrooms, bell pepper, cabbage, carrot, and spring onions.

Keep all the vegetables close to your cooking area because the stir-fry moves quickly once the wok is hot.

5. Heat the wok

Heat a large wok or skillet over high heat.

Add the vegetable oil and allow it to become hot.

6. Stir-fry the beef

Add the marinated beef to the hot wok in a single layer.

Stir-fry for approximately 2–3 minutes, turning the pieces occasionally, until browned and nearly cooked through.

Remove the beef from the wok and set aside.

7. Cook the vegetables

Add the mushrooms, bell pepper, carrot, cabbage, and snow peas to the same wok.

Stir-fry for about 2–3 minutes. The vegetables should become slightly tender while keeping some of their crunch.

Add the spring onions and stir-fry for another 30 seconds.

8. Add the noodles

Add the prepared lo mein noodles to the wok.

Toss gently with the vegetables, using tongs or chopsticks to separate the noodles.

9. Add the sauce

Pour the sauce mixture over the noodles and vegetables.

Toss everything together over high heat for 1–2 minutes, making sure the sauce coats the noodles evenly.

10. Return the beef

Add the cooked beef back to the wok.

Toss everything together for another 1–2 minutes, until the beef is fully cooked and the noodles are hot.

11. Serve

Remove from the heat and serve the Beef Lo Mein immediately.

For the best texture, enjoy it while the noodles are hot and the vegetables are still slightly crisp.

Recipe Tips for Success

• Slice beef against the grain: This makes a noticeable difference in tenderness.
• Use a tender cut: Sirloin, tenderloin, or rump works well.
• Don’t overcrowd the wok: Cook the beef in batches if necessary.
• Keep the heat high: High heat helps create the characteristic stir-fried flavor.
• Prepare everything beforehand: Have the vegetables, sauce, noodles, and beef ready before you begin cooking.
• Don’t overcook the noodles: They will cook again when tossed with the sauce.
• Keep vegetables slightly crisp: Overcooking can make the finished dish watery and soft.
• Don’t skip the marinade: Cornstarch helps coat the beef, while a small amount of baking soda helps tenderize it.

Ingredient Substitutions

Beef

Sirloin, tenderloin, or rump can be used. Another tender beef cut can also work as long as it is thinly sliced.

Lo Mein Noodles

Fresh lo mein noodles are ideal, but cooked egg noodles can be used as an alternative.

Shaoxing Wine

You can use water or rice vinegar according to your preference. Shaoxing wine gives the sauce a deeper, more traditional flavor.

Vegetables

Feel free to substitute vegetables based on what you have available. Broccoli, bok choy, bean sprouts, or other quick-cooking vegetables can work well.

Vegetable Oil

Canola or another neutral cooking oil can be substituted.

Recipe Variations

Spicy Beef Lo Mein

Add sliced chili peppers or a little chili sauce to the wok for extra heat.

Beef and Broccoli Lo Mein

Replace some of the vegetables with small broccoli florets for a classic beef-and-broccoli combination.

Extra Vegetable Lo Mein

Increase the amount of cabbage, carrots, peppers, and snow peas for a more vegetable-packed meal.

Garlic Beef Lo Mein

Add a few cloves of freshly minced garlic while stir-frying the vegetables for a stronger aromatic flavor.

Storage and Reheating

Store leftover Beef Lo Mein in an airtight container in the refrigerator for up to 3–4 days.

To reheat, place the noodles in a skillet over medium heat with a small splash of water. Toss frequently until hot.

You can also reheat individual portions in the microwave, stirring halfway through.

Serving Suggestions
