Beef Lo Mein

This Beef Lo Mein recipe was inspired by Made with Lau‘s Lo Mein recipe. It starts with marinated steak. Then, the steak is pan-seared before being added to sauteed vegetables and lo mein noodles, all tossed in a sauce made with both soy and hoisin sauce.


Noodles: Look for lo mein noodles to use in this recipe. You could also use other egg noodles or pasta noodles if that is all you have on hand.

Steak: I used a New York strip steak in this recipe. It is tender and easy to cut. However, you could also use a different cut of steak like a flank steak or ribeye.

Marinade: You will use soy sauce and hoisin sauce in both the marinade and the sauce. Hoisin sauce is a thick, flavorful sauce that is used a lot for stir-fries, as a dipping sauce, and as a glaze for meats.

Vegetables: This recipe can be a starting point if needed. Feel free to add your favorite vegetables to the mix.

What is the Difference Between Lo Mein and Chow Mein?

There are a couple of differences between lo mein and chow mein. It’s primarily about the preparation of the noodles. Lo mein translates to ‘tossed noodles’ and chow mein translates to ‘fried noodles.’ In lo mein recipes, the noodles are generally cooked ahead of time whereas, in chow mein, the noodles are stir-fried, and cooked with the other ingredients.

How to Cut Steak for Beef Lo Mein

The best way to cut the beef in this recipe is to thinly slice it. For easier slicing, the steak should still be slightly frozen but thawed enough to cut through. First, remove any gristle from the beef. Then, cut the steak against the grain. For wider slices of beef, cut at an angle.

Can I Make This Recipe Spicier?

You can definitely add some kick to this recipe! This recipe is not spicy, but if you want to add a little heat to it, you can do that. Try adding a little sriracha to the lo mein. Or, add some crunchy garlic chili oil or chili garlic sauce.

How to Store & Freeze Leftovers

If you have any of this dish leftover, it’s easy to store in the refrigerator. It will last for 3-4 days in an airtight container. And, while it’s being stored, the sauce will really saturate the rest of the ingredients for even more flavor! To freeze, let the lo mein cool completely. Then, store it in freezer-safe containers. Label and date the containers. It will last for 2-3 months in the freezer. Let it thaw in the refrigerator overnight before reheating.

    I made this for my family a few weeks ago and it was a big hit. The broccoli was crisp-tender, and it was a healthy meal with only a small amount of beef going a long way, and adding all the flavor needed.
