Ingredients You’ll Need

1 tablespoon potato starch (or cornstarch): This thickener helps create a silky sauce that clings to the noodles. Cornstarch works as an excellent alternative.
¼ cup water: Used to dissolve the starch and help form the sauce’s base.
¼ cup dark soy sauce: Richer and less salty than regular soy sauce, it gives the dish its beautiful color and deep flavor.
2 tablespoons shaoxing wine (or rice vinegar): Adds a subtle sweetness and complexity. Rice vinegar can stand in for a hint of that flavor.
1 tablespoon packed brown sugar: This sweetens the sauce, balancing the savory elements perfectly.
½ teaspoon five spice powder: A delightful blend that adds warmth and depth—essential for that authentic Chinese flavor.
½ teaspoon ground white pepper: Offers a gentle hint of spice that works behind the scenes in this dish.
1 teaspoon toasted sesame oil: Imparts a lovely nutty flavor and aroma that enhances the overall taste.
1 lb beef sirloin flap steak, sliced into strips/wedges: A tender cut perfect for stir-frying that absorbs the marinade beautifully.
2-3 tablespoons olive oil (or avocado oil): For frying the beef and vegetables, ensuring a nice sear while adding richness.
1 large carrot, peeled & cut into batons: Adds a sweet crunch—don’t skip this for textural variety.
5 ounces shiitake mushrooms, sliced: Their earthy flavor complements the beef wonderfully.
½ large yellow onion, thinly sliced: Adds sweetness and aromatics when sautéed.
1 red bell pepper, thinly sliced: Brings color and sweetness to the dish.
1 tablespoon minced garlic: Essential for flavor—always use fresh for the best taste.
1 lb pre-cooked frozen lo mein noodles (Twin Marquis brand recommended): Making dinner quick and easy; just heat them up.
6-8 scallions, thinly sliced—plus more for garnishing: Adds a fresh, oniony bite and a pop of color on top.

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 ¼ cup dark soy sauce, 2 tablespoons shaoxing wine (or rice vinegar), 1 tablespoon packed brown sugar, ½ teaspoon five spice powder, ½ teaspoon ground white pepper, and 1 teaspoon toasted sesame oil. Mix until well blended.
Marinate the Beef: Toss the sliced beef sirloin flap steak in 2 tablespoons of the marinade. Coat the beef evenly, then set aside to marinate for at least 30 minutes. Reserve the remaining marinade for later.
Sear the Beef: Heat 2 tablespoons of olive oil in a wok or large skillet over medium-high heat. Once shimmering, add the beef in batches—don’t overcrowd the pan. Sear until golden brown and slightly crispy, which takes about 2-3 minutes. Use a slotted utensil to transfer the cooked beef to a plate and repeat with any remaining beef, adding more oil if necessary.
Sauté the Vegetables: If needed, add 1 tablespoon of oil to the pan. Then, add the carrot batons, sliced shiitake mushrooms, yellow onion, and red bell pepper. Cook until softened and lightly caramelized, about 4-5 minutes. Add 1 tablespoon minced garlic, cooking for an additional 2 minutes until fragrant.
Cook the Noodles: Cook the lo mein noodles according to package directions, which should take no more than 3 minutes from frozen. Drain and set aside.
Combine Everything: Return the seared beef to the pan, along with any accumulated juices. Add the cooked lo mein noodles, remaining marinade, and scallions. Gently stir-fry everything together until well combined and the noodles look glossy. Cook until the sauce has thickened slightly, around 2-3 minutes.
Serve It Up: Remove from heat. If desired, add a splash of hot water or broth to loosen the sauce. Serve the steak lo mein right away with extra sliced scallions for garnish. Enjoy!

Storing & Reheating

Leftovers can be stored in an airtight container at room temperature for a few hours. For refrigeration, keep it sealed and it will last 3-4 days in the fridge. If you’re looking to store it longer, freeze it for up to 3 months. When reheating, use a skillet over medium heat for about 5-7 minutes, stirring gently to avoid sticking—add a splash of water to help revive the texture, if needed.

Chef’s Helpful Tips

Avoid overcrowding the pan: This ensures the beef sears properly, giving it that delicious texture.
Slice the beef against the grain: This helps keep it tender.
Use fresh vegetables: Fresh ingredients elevate the dish so much—avoid those that have seen better days.
Shiitake mushroom alternatives: If unavailable, button or cremini mushrooms can also work but will have a different flavor profile.
Make-ahead option: You can marinate the beef the night before to enhance the flavors.

Steak lo mein captures everything you crave in a warm, filling dish: hearty protein, vibrant veggies, and those beloved noodles that twist around your fork. It invites experimentation, so feel free to personalize it—maybe adding your favorite vegetables or adjusting the sauce. This is your chance to discover your signature touch in the kitchen!

Recipe FAQs

Absolutely! Chicken, pork, or even tofu can work beautifully here. Just adjust the cooking times accordingly; chicken should reach an internal temperature of 165°F.

What can I use instead of lo mein noodles?

Can I make this dish spicy?

Certainly! You can add some chili garlic sauce or sliced fresh chilies when sautéing the vegetables for an extra kick. Start with a small amount and adjust according to your taste.

How do I store leftovers properly?
