A healthy Vegetable Lo Mein

I love making noodles for a quick and easy weeknight dinner. Anything from Thai Red Curry noodles to Singapore noodles, they always take under 30 minutes to make and are filling and delicious.

This recipe for Vegetable Lo Mein is filled with good-for-you veggies like spinach, snow peas, red peppers and carrots. It’s a versatile recipe and you can add any other veggies you love, like broccoli or kale.

This recipe is my own take on the traditional Lo Mein dish.

These noodles are seasoned with just some soy sauce, vegetarian oyster sauce, sesame oil and a touch of coconut sugar for sweetness. If you want to make this recipe gluten-free, just be sure to use a gluten-free soy sauce (or tamari) and gluten-free noodles.

What is Lo Mein Sauce?

Lo Mein sauce is traditionally made with a mix of soy sauce, sesame oil and oyster sauce.

For this recipe, we are using vegetarian oyster sauce (which is made from mushrooms rather than oysters) to keep the recipe vegetarian.

Lo Mein sauce is salty slightly sweet and savory. It’s a well-balanced sauce that stands up to the noodles and packs a big punch!

What Noodles Do I Use for Lo Mein?

The most common type of noodles to use for Lo Mein are Chinese egg noodles. You can find these at most grocery stores or at your local Asian market.

If you can find Chinese egg noodles, you can also just use plain spaghetti noodles or rice spaghetti for a gluten-free option.

How to make Vegetable Lo Mein

Step 1

Cook the noodles in a pot according to the package directions. Make sure not to overcook the noodles since they will continue to cook slightly when stir-frying them in the pan.

Step 2

Add the garlic, ginger and green onions to a pan and sautee. Then add the vegetables to a pan and stir-fry them up until they’re nice and tender. (Don’t be shy to add A LOT of spinach here-it’ll wilt down!)

  • A pan with snow peas, peppers, carrots and spinach in it

Step 3

Add the noodles to the pan, then pour the sauces into the pan and toss everything together until all the noodles are covered. If the noodles start to stick to the bottom of the pan, add a splash of water or vegetable broth.

How to Store and Reheat Veggie Lo Mein

Store any leftover Lo Mein in a sealed container in the fridge for up to 3 days.

Reheat the lo mein in the microwave or in a pan on the stove. If the lo mein noodles are sticking together from being in the fridge, add a small splash of water to the noodles to help loosen them up.

What is Lo Mein? What is the difference between Lo Mein and Chow Mein?

The main difference between Lo Mein and Chow Mein is the cooking method.

Both Lo Mein and Chow Mein use Chinese egg noodles, but with Lo Mein, the noodles are boiled and stir-fried so they’re soft. Chow Mein noodles are stir-fried to be super crispy.

Lo Mein tends to be easier to make at home, and a healthier option.

Tips for the Best Vegan Lo Mein

  • Preheat the pan before adding the oil and vegetables. This will help prevent the veggies from sticking to the pan, and also ensure that the pan is super hot, giving it a nice sizzle similar to a wok.
  • Slightly undercook the noodles before adding them to the pan. The noodles will continue to cook as they stir-fry, so if you cook them completely before adding them to the pan, you’ll end up with slightly overcooked noodles.
  • Always taste and adjust accordingly. Depending on exactly how many veggies and noodles you use, you may end up needing slightly more sauce. Taste and adjust seasoning if needed before serving. (You may just need a tiny extra splash of soy sauce!)
