What is Lo Mein?
Lo Mein is a Chinese noodle dish. The noodles are made with wheat flour and egg and are generally boiled to softness.
Typically Lo Mein noodles are tossed in a light sauce and served with vegetables.
Lo Mein vs. Chow Mein
Lo Mein and Chow Mein are very similar dishes.
The big difference between Lo Mein and Chow Mein is the texture of the noodles. Lo Mein noodles are traditionally boiled or steamed for a soft, smooth noodle texture. Chow Mein noodles are typically pan fried so they have a crispier, firmer texture.
Both dishes incorporate the same foundations of flavor and ingredients. Feel free to call this dish Hakka Noodles, Chow Mein or your very loved Lo Mein.
Ingredients in Vegetable Lo Mein
The great thing about this Lo Mein recipe is that you can customize it to your tastes. Here are the ingredients that I recommend you start with for the noodles and sauce:
- Noodles – use spaghetti (works best), or use thicker chow mein or hakka noodles
- Veggie broth
- Sesame oil
- Ginger paste
- Minced garlic
- Soy sauce
- Vinegar
- Red chili sauce
- Brown sugar
My favorite veggies to use in this easy Lo Mein recipe are cabbage, carrots, bell peppers, green onion, and broccoli.
You can easily add some snap peas and mushrooms if you like. Just remember to add the snap peas in the last few minutes, like the broccoli, so it doesn’t overcook.
Where to Buy Noodles?
You can find noodles at your local Asian foods store or in the Asian section of your nearest international food store. I recommend using chow mein, hakka noodles, or Spaghetti in this Instant Pot Vegetable Lo Mein recipe.
Make sure to not use instant noodles in this recipe. As the name suggests, they are instant and would not work well when pressure cooked.
How to make Vegetable Lo Mein in the Instant Pot?
- Let’s start by gathering the ingredients. This recipe is very simple and uses mostly staples you’re likely to have on hand.
- In a bowl, add all the sauce ingredients. Whisk until evenly combined.
- Add the noodles to the Instant Pot. Then, pour the sauce into the pot above the noodles.
- Add all of your veggies except for the broccoli. It will be added closer to the end.
- Seal your Instant Pot and set it to manual, high pressure, for 4 minutes. (Note: When using spaghetti, check the cooking time on the package. Usually, the cook time in the pressure cooker is half the cook time on the package minus one minute. eg if the package says 12 minutes, cook for 5 minutes in the instant pot)
- When Instant Pot is done cooking, do a quick pressure release.
- Open the lid and add the broccoli florets.
- Stir the noodles with tongs several times, breaking up any that may have clumped together during cooking.
- Close the lid for 3 minutes so the broccoli gets cooked. Make sure to cut the broccoli to small florets.
- Open the lid. Sprinkle some green onions and sesame seeds, then serve.
Tips to make the best Instant Pot Lo Mein

- You could also add sauteed tofu or another favorite protein.
How to Serve Vegetable Lo Mein?
This Lo Mein recipe is hearty enough to stand on its own, served on a plate or in a bowl with chopsticks. But if you want to make it into a more substantial meal, it would pair well with other Chinese-inspired recipes, such as Sweet Corn Soup, Din Tai Fung Green Beans, or Garlic Chili Potatoes.
Garnish with sesame seeds and chopped green onions to add extra texture and flavor.

Any tips on how to make this gluten free? I know that the cook time would be less for the noodles and I would have to use gluten free soy sauce. Just not sure of exact measurements and cook times. Worried that the veggies won’t cook since gluten free noodles need less cook time I think . Thank you!
Hi Rupal – I have not tried with gluten-free noodles, and want to be careful as we don’t want them to get mushy. If you pressure cook even for 1-2 minutes, the thinly cut veggies we have used here will get cooked. Would love to hear back if you give this a try with gluten-free noodles.
How would you add tofu to this?
Hi Robin – I would air fry or saute tofu in a pan. Then add to the lo main after it is pressure cooked. Hope you enjoy it!
Turned out absolutely delicious. I made it on a week night (I usually stay away from cooking on weekday just coz of our crazy work schedules) but wow! so easy and quick to make and tasty too! I’m
Definitely going to add this to my recipes list. Thanks much!😊
Hi Kanika – So happy to hear that. Thank you for sharing it back 🙂
Really good! I doubled the brown sugar, and I used 8 oz broccoli (raw), which I steamed separately and then mixed in.
I recommend making this a couple hours before you want to eat it. It takes a while for the excess water to absorb and for the pasta and everything to absorb the flavors of the sauce.
Have you ever subbed the bags of mixed frozen veggies for the fresh veggies?
Wow! Thank you for this! Our vegan household loved it and omitted the oil. Doubled it, but replaced broccoli with a stir fry mix, brown sugar with maple syrup and also added edimame. I’m putting this in work lunches next week. I can’t believe I didn’t even have to pry the noodles apart. I always have to pry them apart when we have spaghetti! Thanks again!
Hi Christy – So happy to hear that. Thank you for sharing it back 🙂
If you doubled everything did you have to change to cook time at all or was it still just the 4 mins on high?!
This recipe was easy, quick, and delicious! I doubled it for extra leftovers and baked the broccoli for 20 minutes at 400F because I love broccoli and wanted bigger pieces; I still added them at the end and put the lid on for 5 minures and that seemed to help with absorbing the extra liquid. I also added some crushed red pepper at the end since my fiance and I love spicy food. Thin spaghetti worked perfectly for this and the cook time was spot on. Next time I will probably bake up some tofu to add at the end, too! Really looking forward to trying more of your recipes ❤
Hi Kelly – So happy to hear you enjoyed the Lo Mein. Thank you for sharing back!
I have made this recipe before and it was awesome. This time around I don’t have the veggie broth. Could I just use water for the sauce?
Hi Megan – It will be fine to use water in place of broth. You might want to add some more of the sauces and seasoning to compensate. You can add to taste after the noodles are cooked too.
If adding chicken would you add it raw or cooked?
Hi Barbara – You can use raw chicken. To add boneless chicken, cut it into 1-2 inch pieces. Then sauté the chicken in some oil for 1-2 minutes before adding other ingredients. Then follow the recipe. Hope you enjoy the Lo Mein.
Adjusted the chili paste since we like things a little more spicy! I also added chopped up chicken thighs for protein. Husband and I both enjoyed this! Thank you!
Hi Elizabeth – Glad to hear you both enjoyed the Lo Mein!
