If there is something that I pretty much always want, it is Asian takeout and a movie night. I love when we get containers full of warm and delicious food and all huddle together to watch a movie.

Responsible parents don’t get takeout and eat it in front of the TV every night though. So it’s really handy to have some great takeout takeout recipes on hand that are even better than what you can order in. 

This Beef Lo Mein recipe is just that. It’s better than takeout and you can make so many easy variations to make a dish your family falls in love with.


“So very easy to make and so tasty! Will be making again! Thank you!”

What is Lo Mein

Lo Mein is a noodle dish that originates from China, but has been very Americanized. The Americanized version is a combination of stir fried noodles, meat, and vegetables. That is the take on lo mein recipes that we are doing here.

How to Make Lo Mein

While this Lo Mein recipe is easy to make, it does have a few steps that might make it feel daunting. Here is a brief overview to show you the simplicity of this dinner.

  1. Start this recipe by slicing the flank steak very thin and marinating it for 2 to 24 hours in our homemade sauce.
  2. When ready to cook, make the noodles.
  3. While the noodles are cooking, sauté the flank steak, then cook the vegetables, and combine it all with the noodles and sauce.

Lo Mein Noodles

Traditionally, Lo Mein is made with egg noodles. In the United States you can find wide noodles that are labeled “Lo Mein” that are made with wheat. These noodles are easy to find in the international aisle of the grocery store.

Those are the noodles you see pictured here. I love how they absorb and hold on to the sauce in this recipe. Their texture and taste are perfect.

That being said, you can replace it with any kind of noodle your family loves, even just typical spaghetti. It will work in this recipe and you will love it.

Lo Mein Sauce

The sauce for this Beef Lo Mein recipe is a made with just four ingredients, but the combination of their flavors is perfection. We use these ingredients for both the sauce and the marinade.

  • Soy Sauce
  • Brown Sugar
  • Oyster Sauce
  • Chile Paste

Marinating Flank Steak and Skirt Steak

If you aren’t able to find flank steak for this recipe, you can replace it with skirt steak. The two are very similar, and both work well in this recipe.

Both cuts of meat are fairly lean. Because of this, just like in my Carne Asada, they need to be marinated. The soy sauce we use in this recipe is packed with salt and works just like the brine we use in my Turkey Breast recipe. It breaks down the meat and tenderizes it.

Though it adds extra time to the recipe, it is important to marinate the meat. You will enjoy this dish infinitely more if you do this step. I encourage you to marinate the night before to make cooking the next evening a snap.

Variations and Substitutions

There are a few swaps you can do for this recipe to make it something everyone will love.

  • Change out the vegetables: This is the easiest swap to make. You are looking for roughly 6 cups of vegetables. Find ones that you will love. Zucchinis will add more liquid, but they aren’t a deal breaker. Make this super simple by buying a bag of frozen stir fry vegetables.
  • Replace Oyster Sauce with Hoisin Sauce: If you can’t find Oyster Sauce, Hoisin Sauce is a great substitute. It will change the flavor a little, but you will still enjoy it.
  • Leave out the chili paste: I say this very begrudgingly, because chili paste is just the best. But if you can’t handle heat, leave this out and still make this great lo mein recipe.
  • Swap Flank Steak for Skirt Steak: As mentioned above, both cuts of meat will work well in this recipe.
  • Use any long noodle: If you can’t find Lo Mein Noodles, substitute any long noodle in this recipe (such as spaghetti or fettuccine).

Other Takeout Fakeouts

If you are trying to eat a little healthier or save money, or honestly both, here are some other great dinners that will make you feel like you are eating out.

  • Butter Chicken: We make this recipe all the time, it is a great take on an Indian classic, and my kids love it.
  • Chicken Fried Rice: This fried rice recipe is done in about 20 minutes!
  • Chicken Tacos: We are obsessed with this recipe and I want to tell the entire world about it.
  • Taco Bell Quesadillas: Yes. They really do taste as good (or better) than takeout!

    Can you eat this if you’re on a diet
    Thanks in advance.xx

    • Lisa Longley says

      Hi Carol! That’s a really hard question to answer because all diets are different. My personal feeling is that if you are attempting to lose weight, eating in moderation rather than cutting things out all together is a great path to take so you don’t feel deprived. Maybe Beef Lo Mein for dinner tonight, and salads tomorrow night.

    I made this tonight for dinner. Very Very good!!! I used Spaghetti noodles though. Marinated the meat 24 hours. Used Flank steak as my butcher doesn’t carry skirt. Added bean sprouts and used a can of diced water chestnuts instead of sliced which I thought allowed for more bites with a little “crunch” factor. I also didn’t know where to find chili paste so I didn’t use that either. My husband really enjoyed it as well. Thank you another fabulous recipe!

    • Lisa Longley says

      I’m so happy you liked it!

  9. Karen Speece says

    Made the beef lo mein for dinner, it was good but seemed way too salty tasting to me. How can I help that? I used low sodium soy sauce even

    • Lisa Longley says

      I’m sorry to hear that! Next time you could try replacing some of the soy sauce with water.
