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 or 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 to manual, high pressure, 4 minutes. (Note: When using spaghetti, check the cook 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
- Use the right variety of noodles.
- Make sure to pour the sauce over the noodles so they all get a bit wet.
- Take the steel insert out of the instant pot once cooked, so the noodles don’t overcook.
- Adjust the sauces to your taste when serving.
- This noodles recipe is very versatile, you can change the vegetables and sauces to your preference.
- 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 or Garlic Chili Potatoes.
Garnish with sesame seeds and chopped green onions to add extra texture and flavor.

Any recommendations for gluten free noodles like rice noodles or GF pasta?
Hi Laurie – Sorry, I have not tried this with gluten-free pasta/noodles. I think they might get overcooked in the same time in the instant pot.
I have made this a couple of times with GF Barilla Pasta. I made it once with the wider spaghetti noodles. I can’t think of what they are called. Oh, fettuccine, I think. I also made it with the small pasta like rotini. I liked it best with the first kind but my husband like it best with the small noodles. Just don’t overcook the noodles. About 1/2 the cook time on the package or even less. I’ve been doing 4 minutes, I think . HTH.
Thanks for sharing your experience, Sandy!
Can ramen noodles be used?
Hi Jennie – I have not tried this with ramen noodles. If they are quick-cooking noodles, most likely they won’t work for pressure cooking.
Can I use fresh ginger instead?
Hi Jenn – Sure, you can use freshly grated ginger too. Hope you enjoy the noodles!
What kind of vinegar are you using?
I believe she uses rice vinegar.
I think it might be regular vinegar because she would have said rice vinegar? I’m totally guessing, I think unless she specifies that I would use regular white vinegar.
If you click on the link it takes you to amazon so you can buy Rice Vinegar. That’s what I’m going to use.
Thanks for checking everyone. I used rice vinegar, but have tried this recipe with white vinegar too. I have clarified in the ingredients now. Hope you enjoy the noodles!
The noodles don’t look like dry ones. Are they fresh or are they pre cooked?
Hi Sandra – They are dry noodles, and no need to precook before using in the recipe. Thin spaghetti would also work great in the recipe. Hope you enjoy it!
Any tips on how to add tofu to this? Thank you
Hi Sarina – I would saute or air fry tofu before adding to this lo Mein. You can add it after pressure cooking the noodles. Hope you enjoy them!
Great instructions and came out perfect ! Used whole wheat and that was tasty & Healthy. Great easy dinner option, thank you for bringing us together to cook
Hi, So happy to hear that. Thank you sharing back 🙂
This is really good and very quick and easy. I actually made it two days in a row! Can’t wait to explore more of Meeta’s recipes! If you’re in a hurry, frozen veggies (defrosted quickly in warm water) work just as well as chopped fresh ones and shave a bunch of prep time.. that’s how I made it the second day, turned out great. Thanks Meeta
Hi Katie – So happy to hear that. Thank you for sharing your experience 🙂
Would love to add chicken peices to this. How would you suugest to cook this please 🙂
Hi Selena – To add boneless chicken, cut it into 1-2 inch pieces. Then saute the chicken in some oil for 1-2 minutes before adding other ingredients. Then follow the recipe. Hope you enjoy the Lo Mein.
I have tried this recipe twice and it was amazing both times! It does have a little heat, but my husband and I like that. Very easy recipe and comes out perfect every time!
Hi Meghan – So happy to hear that. Thank you for sharing your experience 🙂
