Ingredients You’ll Need

1 tablespoon potato starch (or cornstarch): Helps thicken the sauce and gives it a glossy finish. Cornstarch is a great substitute if potato starch is unavailable.
¼ cup water: This helps dissolve the starch, making it easy to blend into the sauce.
¼ cup dark soy sauce: Provides depth and rich flavor – it’s essential for that authentic taste.
2 tablespoons shaoxing wine (or rice vinegar): Adds a lovely acidity that brightens the dish. If unavailable, rice vinegar is an acceptable replacement.
1 tablespoon packed brown sugar: Balances the saltiness of the soy sauce and enhances caramelization.
½ teaspoon five spice powder: Brings in warm, aromatic notes typical in Chinese cuisine. If you’re out, a mix of cinnamon, star anise, and cloves can work in a pinch.
½ teaspoon ground white pepper: Gives a subtle heat that rounds out the flavor profile.
1 teaspoon toasted sesame oil: This fragrant oil adds nutty richness to the sauce.
1 lb beef sirloin flap steak, sliced into strips/wedges: A tender cut that stays juicy during cooking, essential for the best lo mein experience.
2-3 tablespoons olive oil (or avocado oil): Used for searing the beef and stir-frying the vegetables.
1 large carrot, peeled & then cut into batons: Adds sweetness and vibrant color.
5 ounces shiitake mushrooms, sliced: Great for their meaty texture and earthy flavor.
½ large yellow onion, thinly sliced: Balances the dish with sweetness when cooked.
1 red bell pepper, thinly sliced: Adds crunch and sweetness.
1 tablespoon minced garlic: For that aromatic base that makes every stir-fry irresistible.
1 lb pre-cooked frozen lo mein noodles (Twin Marquis brand recommended): So easy to use and saves time, perfect for a quick meal.
6-8 scallions, thinly sliced: A bright finishing touch, enhancing both flavor and presentation.

How to Make Ridiculously-Good Steak Lo Mein

Prepare the Marinade: In a bowl, combine 1 tablespoon potato starch and ¼ cup water. Whisk until fully dissolved. Add in ¼ cup dark soy sauce, 2 tablespoons of shaoxing wine, 1 tablespoon packed brown sugar, ½ teaspoon five spice powder, ½ teaspoon ground white pepper, and 1 teaspoon toasted sesame oil. Whisk again until everything is well incorporated.
Marinate the Beef: Place the sliced beef sirloin flap steak in a large bowl and pour 2 tablespoons of the prepared sauce over it. Toss thoroughly until the beef strips are evenly coated. Let this marinate for at least 30 minutes, allowing the flavors to penetrate the meat—setting aside the excess sauce for later use.
Sear the Beef: In a wok or large skillet, heat 2 tablespoons olive oil over medium-high heat. Once shimmering, add the marinated beef in batches, being careful not to overcrowd the pan. Sear for 2-3 minutes until golden brown and slightly crispy, then transfer to a clean plate. Repeat this process, adding oil as needed, until all the beef is cooked.
Sauté the Vegetables: If needed, add 1 tablespoon of oil to the same pan. Incorporate the sliced carrots, shiitake mushrooms, yellow onion, and red bell pepper. Sauté until softened and lightly caramelized, about 4-5 minutes. Add the minced garlic and continue cooking for another 2 minutes until fragrant.
Cook the Noodles: Meanwhile, on a separate burner, cook 1 lb of pre-cooked frozen lo mein noodles according to package instructions—about 3 minutes. Once cooked, drain and set aside.
Combine Everything: Add the cooked beef back into the pan along with any juices. Toss in the lo mein noodles, reserved marinade, and sliced scallions. Stir-fry everything together until combined and glossy, about 2-3 minutes as the sauce thickens around the beef and noodles.
Serve: Remove from the heat. If desired, a splash of hot water can be added to loosen up the sauce’s consistency. Plate your delicious steak lo mein garnished with extra scallions. Enjoy your creation fresh out of the pan!

Storing & Reheating

Leftover steak lo mein can be stored at room temperature for up to two hours but is best refrigerated in an airtight container, where it will stay fresh for up to 3 days. For longer storage, freeze in a freezer-safe container for up to 3 months. To reheat, simply place it in a skillet over medium heat, adding a splash of water or broth to restore moisture. Heat until warmed through, keeping an eye on the texture to ensure the noodles don’t become mushy.

Chef’s Helpful Tips

Avoid overcrowding the pan when searing beef; this allows for a nice golden crust.
Ensure your beef is sliced thinly against the grain for tender bites.
If you prefer your veggies crisp, add them to the pan after the beef is almost done cooking.
Aim for a hot pan to achieve the best sear on your beef – this enhances flavor.
Leftover marinade can also be used as a drizzle over the finished dish for extra flavor, just ensure it’s cooked first to eliminate any raw meat contaminants.

The combination of savory, perfectly-fried beef with tender lo mein and vibrant vegetables creates an inviting plate that’s hard not to love. I encourage you to get creative with your choice of vegetables or even experiment with different proteins. Who knows? This could become your go-to dish. Enjoy this weeknight favorite or impress family and friends; taste truly awaits!

Recipe FAQs

Can I use other types of vegetables?

Absolutely! You can customize your lo mein by adding vegetables like broccoli, snap peas, or bok choy. Just keep in mind cooking times might vary, so adjust accordingly for tenderness.

What can I use if I don’t have dark soy sauce?

If you don’t have dark soy sauce, you can use regular soy sauce, but the flavor might be slightly less rich. You can also add an extra pinch of brown sugar to mimic some of that sweetness.

Can I make this dish vegetarian?

Yes! You can easily substitute the beef with tofu or tempeh and use vegetable broth instead of meat. Just ensure to use a soy sauce that suits your dietary needs.

How can I make this dish gluten-free?

For a gluten-free option, swap out the regular soy sauce for a gluten-free soy sauce or tamari. Ensure that your noodles are also gluten-free, as many traditional lo mein noodles contain wheat.
