Ingredients You’ll Need
- 1 tablespoon potato starch (or cornstarch): This helps thicken the sauce, giving it a luscious texture. Cornstarch can be used as a substitute if needed.
- ¼ cup water, plus more as desired: Used to create the sauce, the water hydrates the starch for smoothness.
- ¼ cup dark soy sauce: This adds a deep, umami flavor that regular soy sauce can’t match.
- 2 tablespoons shaoxing wine (or rice vinegar): Essential for depth; rice vinegar can substitute if you’re out.
- 1 tablespoon packed brown sugar: Balances the savory flavors with a hint of sweetness.
- ½ teaspoon five spice powder: Brings a unique aromatic flavor profile; if not available, it can be skipped or replaced with a pinch of cinnamon and star anise.
- ½ teaspoon ground white pepper: For a subtle spice; black pepper is a good alternative if needed.
- 1 teaspoon toasted sesame oil: Adds a nutty aroma; use carefully, as it’s potent.
- 1 lb beef sirloin flap steak, sliced into strips/wedges: This cut is tender and flavorful, making it perfect for quick cooking.
- 2-3 tablespoons olive oil (or avocado oil), plus more if needed: Used for searing the beef and cooking the vegetables, both oils have high smoke points.
- 1 large carrot, peeled & then cut into batons: Adds sweetness and crunch. You can also use bell pepper for a twist.
- 5 ounces shiitake mushrooms, sliced: Their unique flavor complements the beef beautifully, but feel free to substitute with button mushrooms.
- ½ large yellow onion, thinly sliced: Essential for a classic flavor base.
- 1 red bell pepper, thinly sliced: Adds color and sweetness to the dish.
- 1 tablespoon minced garlic: Infuses the dish with a comforting aroma.
- 1 lb pre-cooked frozen lo mein noodles: Choose a brand with good texture, like Twin Marquis; they simplify the cooking process.
- 6-8 scallions, thinly sliced plus more for garnishing: Provides a fresh crunch, tying all the flavors together.
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, then 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. Whisk until combined.
- Marinate the Beef: Add the sliced 1 lb beef sirloin flap steak to a large bowl and cover with 2 tablespoons of the sauce. Toss well until the beef is evenly coated. Set aside to marinate for at least 30 minutes, while keeping the remaining sauce aside.
- Sear the Beef: In a wok or large skillet, heat 2 tablespoons of olive oil over medium-high heat until shimmering. Working in batches, add the marinated beef, ensuring not to overcrowd the pan. Sear until golden brown and slightly crispy, about 2-3 minutes. Transfer the cooked beef to a clean plate and set aside. If needed, add more oil between batches.
- Sauté the Vegetables: After the beef is set aside, add 1 tablespoon of olive oil to the pan. Throw in the batons of 1 large carrot, sliced 5 ounces shiitake mushrooms, ½ large yellow onion, and thinly sliced 1 red bell pepper. Cook until softened and lightly caramelized, about 4-5 minutes. Add 1 tablespoon minced garlic and cook until fragrant, about 2 minutes.
- Cook the Lo Mein: In a separate pot or burner, cook 1 lb pre-cooked frozen lo mein noodles according to package directions, which should take no more than 3 minutes from frozen. Drain the noodles and set aside.
- Combine Everything: Return the seared beef to the pan, including any residual juices. Add the cooked lo mein noodles, the remaining sauce, and 6-8 sliced scallions. Stir-fry gently until well combined and the noodles become glossy, continuing to cook until the sauce thickens and glazes the beef, around 2-3 minutes.
- Serve: Remove from heat and, if desired, add a splash of hot water or broth to loosen the sauce. Serve immediately with extra scallions for garnish, and enjoy!
Storing & Reheating
To store leftovers, allow the steak lo mein to cool at room temperature for no more than two hours before transferring it to an airtight container for refrigeration. It stays fresh for up to 3 days. For longer storage, you can freeze it for up to 3 months—just remember to use a freezer-safe container. When reheating, warm it gently in a pan over medium heat for about 5-7 minutes, adding a splash of water or broth for moisture. Note that the texture of the noodles may change slightly, but a bit of extra stirring will bring them back to life.
