Ingredients You’ll Need

1 tablespoon potato starch (or cornstarch): This helps thicken the sauce and gives it a nice glossy finish.
¼ cup water: Used to dissolve the starch, creating a smooth sauce.
¼ cup dark soy sauce: Adds depth and umami flavors; regular soy sauce can be used if needed.
2 tablespoons shaoxing wine (or rice vinegar): Introduces a lovely acidity, but use rice vinegar for a quicker substitute.
1 tablespoon packed brown sugar: Balances saltiness and enhances the overall flavor.
½ teaspoon five spice powder: This Chinese spice blend adds warmth and complexity.
½ teaspoon ground white pepper: Slightly spicy and aromatic; provides a different profile than black pepper.
1 teaspoon toasted sesame oil: Adds a nutty aroma to the dish.
1 lb beef sirloin flap steak, sliced into strips/wedges: A flavorful cut perfect for quick stir-frying.
2-3 tablespoons olive oil (or avocado oil): Enough to provide a non-stick surface for searing the beef.
1 large carrot, peeled & then cut into batons: Adds natural sweetness and crunch to the dish.
5 ounces shiitake mushrooms, sliced: Earthy flavor and chewy texture; feel free to substitute with other mushrooms.
½ large yellow onion, thinly sliced: Provides sweetness and depth when sautéed.
1 red bell pepper, thinly sliced: For color and sweetness.
1 tablespoon minced garlic: A must for that aromatic kick!
1 lb pre-cooked frozen lo mein noodles (I use Twin Marquis brand): No need for boiling; these cook up beautifully when added directly to the stir-fry.
6-8 scallions, thinly sliced: Freshness and a mild bite, perfect for garnishing!

How to Make Ridiculously-Good Steak Lo Mein

Prepare the Sauce: In a bowl, mix 1 tablespoon potato starch (or cornstarch) with ¼ cup water. Whisk until fully dissolved. Add ¼ cup dark soy sauce, 2 tablespoons shaoxing wine (or rice vinegar), 1 tablespoon brown sugar, ½ teaspoon five spice powder, ½ teaspoon ground white pepper, and 1 teaspoon toasted sesame oil. Whisk together until combined.
Marinate the Beef: Place 1 lb sliced beef sirloin flap steak in a large bowl. Cover with 2 tablespoons of the prepared sauce, tossing to coat well. Let it marinate for at least 30 minutes; this allows the flavors to seep into the meat.
Sear the Beef: In a wok or large skillet, heat 2 tablespoons of olive oil (or avocado oil) over medium-high heat. When the oil shimmers, add the marinated beef in batches to avoid overcrowding. Sear until golden brown and slightly crispy, about 2-3 minutes per batch. Use a slotted utensil to transfer the beef to a clean plate and set aside. Repeat, adding more oil if needed.
Cook the Vegetables: After searing the beef, add 1 tablespoon of oil if necessary to the pan. Toss in the carrot batons, 5 ounces sliced shiitake mushrooms, ½ sliced yellow onion, and 1 thinly sliced red bell pepper. Cook until softened and lightly caramelized, approximately 4-5 minutes. Add 1 tablespoon minced garlic and continue cooking until fragrant, about 2 minutes.
Prepare the Noodles: While the vegetables cook, follow package directions for cooking the 1 lb of pre-cooked frozen lo mein noodles (they usually take just 3 minutes). Drain and set aside.
Combine and Stir-Fry: Return the seared beef to the pan, along with any accumulated juices. Add in the drained lo mein noodles, the remaining sauce, and 6-8 thinly sliced scallions. Stir-fry until everything is well combined, and the noodles are glossy with sauce. Cook until the sauce thickens and coats everything nicely, about 2-3 minutes.
Serve: Remove from heat and, if desired, splash in a bit of water or broth to loosen the sauce. Serve immediately, garnished with extra sliced scallions for a pop of color and flavor. Enjoy your meal!

Storing & Reheating

To store your leftover steak lo mein, transfer it to an airtight container and refrigerate for up to 3 days. If you want to store it longer, freeze it in a freezer-safe container for up to 3 months. When reheating, a quick microwave session for a minute or two should do the trick, or you can heat it on a skillet over medium heat. Just remember that the texture might slightly change after freezing, so try adding a splash of broth to refresh it.

Chef’s Helpful Tips

Avoid overcrowding the pan while searing the beef, as it can lead to steaming rather than browning.
If you have time, let the beef marinate longer for more intense flavors.
Use fresh ingredients for optimal flavor; the fresher the veggies, the better the dish!
If the noodles stick together, rinse them briefly with warm water to separate.
Keep the heat high while stir-frying to quickly cook and enhance your ingredients.

Creating Ridiculously-Good Steak Lo Mein is straightforward and rewarding. Don’t hesitate to switch up the vegetables based on your preferences or whatever you have on hand. Maybe you want napa cabbage, snap peas, or even some broccoli? The world is your oyster here.

Give yourself permission to experiment with the spices or add that extra splash of soy sauce to elevate the flavor. You’ll soon find this dish becoming a firm favorite around your table! Let the deliciousness of this meal fill your kitchen, and most importantly, remember to savor every bite.

Absolutely! Chicken or shrimp can be excellent substitutes for beef in this lo mein recipe. Just adjust the cooking time accordingly. Chicken should be cooked until no longer pink, and shrimp should turn opaque and curl up slightly.

What kind of vegetables can I add?

Feel free to add or substitute any vegetables you enjoy or have on hand. Broccoli, bell peppers, snap peas, or bok choy all work beautifully in this stir-fry. Just remember to cook harder vegetables like carrots a bit longer to ensure they soften.

How can I make this dish gluten-free?

Can I make this dish ahead of time?
