This beef lo mein is a family favorite! Tender beef, crunchy veggies, and a savory sauce make this restaurant-style dish totally delicious.
What Makes This Recipe So Good
- This Chinese-inspired dish is super fun to throw together! Once all veggies are chopped and the beef is sliced, it takes less than 20 minutes to cook. Start by stir-frying the beef, then the veggies, and finish by tossing everything together in the same wok or skillet!
- This beef lo mein is loaded with tender chunks of the tastiest beef! A touch of soy sauce and garlic is enough to leave this beef exploding with delicious flavor.
- A variety of crunchy vegetables add a nice bite to the creamy sauce and noodles in this dish. Thinly sliced carrots, peppers, mushrooms, and cabbage are cooked just enough to maintain their bite and delightfully fresh flavor!
Key Ingredients
Flank Steak – This lean cut of beef is incredible in this recipe! To prepare the flank steak for this beef lo mein, slice it into 1/4-inch thick strips against the grain. Be careful not to slice the steak any thinner than 1/4-inch, since that could result in tough/chewy beef.
Soy Sauce – We use plenty of soy sauce in this beef lo mein recipe! However, you have the option to use regular soy sauce, low-sodium soy sauce, or even tamari (gluten-free soy sauce) in this recipe. All three versions of this Asian staple ingredient will taste great in this dish.
Napa Cabbage – This cabbage originates from China, and is traditional to most lo mein recipes. Napa cabbage cooks up beautifully in this recipe and soaks up all of the delicious flavors of this dish. Start by washing your cabbage very well, making sure to rinse out the dirt in between each leaf. Then place it on its side on a cutting board and slice, starting from the top leafy part, into thin 1/4 to 1/8-inch strips.
Chef’s Tips
- If you have a wok, use it! Though if you don’t own a wok, you can use a large skillet to cook up this beef lo mein instead. Regardless of the type of pan you use, the key to stir frying in this recipe is to maintain a relatively high heat at all times.
- While fresh lo mein noodles taste best, dry lo mein noodles will work as well in this recipe. To locate lo mein noodles in your grocery store, simply take a look down the Asian aisle – that’s where I typically find them! And if you have a specialty Asian grocery store in your area, then definitely make a trip there.
- I recommend you enjoy this recipe immediately after cooking. There’s not much better than a steaming hot bowl of homemade beef lo mein – YUM! Though if you have any leftovers, you can store them in an airtight container in the fridge for up to three days.
