Ingredients You’ll Need

8 oz lo mein noodles: These soft, chewy noodles are essential for the dish. You can substitute with spaghetti if needed, but it won’t have the same authentic texture.
1 lb flank steak or sirloin, thinly sliced: Flank steak is ideal for this dish because it’s tender and full of flavor, but sirloin is a great alternative if you’re looking for something more budget-friendly.
2 tbsp soy sauce: This adds depth and saltiness to the dish. Opt for low-sodium soy sauce if you’re watching your sodium intake.
2 cloves garlic, minced: Fresh garlic elevates the flavor profile. Feel free to add more if you’re a garlic lover!
1 tbsp honey or sugar: Just a touch of sweetness balances the savory elements beautifully.
2 tbsp vegetable oil: This oil is great for stir-frying. You can use canola or peanut oil as alternatives.
1 cup broccoli florets: Fresh broccoli adds not only nutrition but also a nice crunch. Frozen broccoli works too; just adjust the cooking time.
1/2 cup sliced bell peppers: Feel free to get colorful with your choices—red, yellow, or green bell peppers are all perfect.
1/2 cup shredded carrots: Sweet and crunchy, these add both flavor and vibrant color to your dish.
1 tsp cornstarch (optional): If you prefer a thicker sauce, this can help achieve that luxurious feel.
2 tbsp water (optional, for sauce): Helps dissolve the cornstarch if used.

How to Make Beef Lo Mein

Cook the Noodles: Begin by cooking the 8 oz lo mein noodles according to package instructions. Once they’re al dente, drain them and set them aside, keeping in mind that they will continue to cook slightly when combined with the rest of the dish.
Prepare the Beef: While the noodles are cooking, thinly slice the 1 lb flank steak or sirloin against the grain. Lightly season it with 2 tbsp soy sauce; this adds flavor while you prep the rest of the ingredients.
Make the Sauce: In a bowl, combine 2 tbsp soy sauce, minced 2 cloves of garlic, and 1 tbsp honey or sugar. Whisk everything together until blended; this sauce is the magic that ties your dish together.
Heat the Oil: In a large pan or wok, heat 2 tbsp vegetable oil over medium-high heat. Ensure the oil is nice and hot before proceeding to the next step.
Cook the Beef: Add the beef to the pan in a single layer. Allow it to cook without stirring for about 2-3 minutes until browned, then flip and cook for another minute. This step locks in the beef’s juices and creates a lovely sear.
Stir-Fry the Veggies: Remove the beef from the pan and set it aside. In the same pan, stir-fry 1 cup broccoli florets, 1/2 cup sliced bell peppers, and 1/2 cup shredded carrots. Cook them for about 3-5 minutes until they are tender-crisp, retaining that vibrant color.
Combine: Return the cooked beef to the pan. Add the drained lo mein noodles on top, making sure they’re ready to soak in all the goodness.
Add the Sauce: Pour in the prepared sauce, tossing everything together gently until it’s all beautifully coated. This step is crucial; you want the noodles and vegetables to absorb that delicious sauce!
Thicken the Sauce (Optional): If you like a thicker sauce, mix 1 tsp cornstarch with 2 tbsp of water, then pour it into the pan. Stir for another 2-3 minutes, until the sauce thickens to your liking.
Serve: Once everything is heated through and well combined, serve hot. Enjoy this comforting dish straight from the stovetop!

Storing & Reheating

To store leftover beef lo mein, let it cool before placing it in an airtight container. It can be kept at room temperature for about 2 hours, or refrigerated for up to 3 days. If you want to store it for longer, consider freezing it for up to 3 months in a freezer-safe container. To reheat, simply microwave in 1-minute intervals, stirring in between, or reheat in a pan over medium heat. Be aware that the texture may change slightly after freezing, so refreshing it with a splash of soy sauce or a drizzle of oil can help bring back some moisture.

Chef’s Helpful Tips

Avoid overcooking the beef by slicing it thinly; this ensures it cooks quickly and remains tender.
If you’re adding extra vegetables, make sure they’re all cut uniformly to ensure even cooking.
For a spicy kick, toss in some red pepper flakes or a dash of chili sauce when you add the sauce.
Timing is key—have all your ingredients prepped and ready to go before you start cooking, as stir-frying is a fast process.

When you think of a comforting yet flavorful dish, beef lo mein should be at the forefront. Its easy preparation, along with the ability to customize it to your liking, makes it an ideal solution for busy weeknights or gatherings. Enjoy making this dish often—there’s always room for improvement, be it trying different vegetables or experimenting with sauces.

Recipe FAQs

Can I use a different type of beef for this recipe?

Absolutely! While flank steak or sirloin are the best choices for their tenderness, you can also use ribeye, ground beef, or even chicken or tofu for a different protein option. Just remember to adjust cooking times accordingly.

What vegetables can I use in lo mein?

Lo mein is fantastic because it’s incredibly versatile. In addition to broccoli, bell peppers, and carrots, consider adding snow peas, bean sprouts, mushrooms, or bok choy. Use whatever is in season or what you have on hand!

Can I make beef lo mein in advance?
