Ingredients You’ll Need

1 tablespoon potato starch (or cornstarch): This helps thicken the sauce for a glossy finish. Cornstarch works just as well if you don’t have potato starch.
¼ cup water: Essential for dissolving the starch and creating a smooth sauce.
¼ cup dark soy sauce: Adds depth and richness; the dark variety is key for that beautiful color.
2 tablespoons shaoxing wine (or rice vinegar): Provides a hint of acidity that balances the flavors nicely.
1 tablespoon packed brown sugar: This adds sweetness that complements the savory elements beautifully.
½ teaspoon five spice powder: A quintessential Chinese seasoning that elevates the overall flavor profile.
½ teaspoon ground white pepper: For a subtle kick without overpowering the dish.
1 teaspoon toasted sesame oil: This adds a nutty richness that enhances the flavors.
1 lb beef sirloin flap steak, sliced into strips/wedges: A tender cut ideal for stir-frying and soaking up flavors.
2-3 tablespoons olive oil (or avocado oil): Used for searing the beef and sautéing the vegetables.
1 large carrot, peeled & then cut into batons: Adds color and crunch.
5 ounces shiitake mushrooms, sliced: These mushrooms provide an earthy depth you’ll love.
½ large yellow onion, thinly sliced: For sweetness and texture.
1 red bell pepper, thinly sliced: Adds sweetness and a pop of color.
1 tablespoon minced garlic: The aroma of garlic cooking is always a welcome addition!
1 lb pre-cooked frozen lo mein noodles: The convenience of pre-cooked noodles means you can focus on flavor.
6-8 scallions, thinly sliced: For freshness and a final touch of flavor.

How to Make Ridiculously-Good Steak Lo Mein

Prepare the Sauce: In a bowl, combine 1 tablespoon potato starch and ¼ cup water. Whisk until fully dissolved. Add ¼ cup dark soy sauce, 2 tablespoons 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 well combined.
Marinate the Beef: Place the sliced beef sirloin flap steak into a large bowl and cover it with 2 tablespoons of the sauce. Toss well to coat the beef evenly, then set aside to marinate for at least 30 minutes.
Sear the Beef: In a wok or large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once the oil shimmers, add the beef in batches, ensuring not to overcrowd the pan. Sear until the beef is golden brown and slightly crispy, about 2-3 minutes. Use a slotted utensil to transfer the cooked beef to a clean plate and set aside. Repeat with remaining beef, adding more oil only if necessary.
Cook the Vegetables: If needed, add 1 tablespoon of oil to the pan. Add the carrots, shiitake mushrooms, onion, and bell pepper. Cook until softened and lightly caramelized, about 4-5 minutes. Add 1 tablespoon minced garlic and continue cooking for an additional 2 minutes until fragrant.
Prepare the Noodles: Meanwhile, cook the lo mein noodles according to package directions, typically no longer than 3 minutes from frozen. Drain and set them aside.
Combine All Ingredients: Return the seared beef to the pan, along with any leftover juices. Add the cooked noodles, the remaining sauce, and sliced scallions. Stir-fry everything gently until well combined, and the noodles are glossy. Continue cooking until the sauce thickens into a glaze over the beef, approximately 2-3 minutes.
Final Touches: Remove from heat. If you prefer a looser sauce, add a splash of hot water or broth to reach your desired consistency. Serve immediately, garnished with extra sliced scallions.

Storing & Reheating

To store your leftover steak lo mein, let it cool and transfer to an airtight container. You can keep it at room temperature for a couple of hours or refrigerate for up to 3-4 days. For long-term storage, freeze it in a freezer-safe container for up to 3 months. When you’re ready to enjoy, simply reheat in a sauté pan over medium heat, adding a little water to restore moisture, and cook until heated through.

Chef’s Helpful Tips

Avoid overcrowding the pan while searing the beef to achieve that perfect golden-brown crust.
Marinating the beef for longer, if time allows, enhances the flavor. Aim for up to 2 hours.
Keep the heat high during the stir-frying process to achieve a good char on the vegetables.
If you’re looking to mix up flavors, feel free to include your favorite vegetables—broccoli, snap peas, or bok choy work excellently.
If using fresh noodles, adjust the cooking time accordingly, as they may need a slightly longer time.

There’s something truly special about mastering a dish like this. Not only do you get to enjoy flavors that remind you of your favorite Chinese restaurant, but you also have the thrill of creating it yourself in the comfort of your own kitchen. Don’t shy away from playing around with ingredients — cooking is an adventure, after all!

Recipe FAQs

Can I use different types of meat?

Absolutely! This recipe is versatile. Chicken, shrimp, or even tofu can be substituted for the beef sirloin. Just adjust the cooking times accordingly to ensure everything is cooked perfectly.

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

If dark soy sauce isn’t in your pantry, you may use regular soy sauce, but consider adding a touch more brown sugar for that sweet richness and deeper color, which dark soy sauce provides.

Can I make this dish vegetarian?

Certainly! You can swap out the beef for tofu or your favorite plant-based protein. Use vegetable broth or water instead of any animal-based ingredients in the sauce for a completely vegetarian version.

How do I avoid overcooked vegetables?

To keep your vegetables vibrant and crisp, add them to the pan in the order they take the longest to cook, and avoid cooking at too low a temperature. Aim for a quick stir-fry method to retain their freshness and color.
