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

- 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.

The broccoli stayed hard & crunchy for us – I think I should haven’t added more water & put it on sauté to help it cook as there was v little liquid sauce by then. Also, the whole dish tasted far too strongly of ginger/was v fiery. I used grated fresh ginger. Not sure if that is the same as American ginger paste? But I will put less in next time – I was probably too generous and then the kids couldn’t eat it! The basic recipe is ok… but I think I’ll tweak it a bit next time.
Hi Flora – Sorry to hear you all could not enjoy the lo mein due to the strong ginger taste. I have never had anyone mention they felt the ginger was too strong, maybe just add less the next time. I do use fresh ginger in most of my cooking. Just reduce the quantity next time for your family. For broccoli, I make very small florets and add it at the end, as it would completely overcook if pressure cooked with the noodles. The small florets cook and soften from the heat of the noodles. I hope that helps. Please do tweak the recipe to you preference next time 🙂
This recipe did not work? We followed all directions fully and we received the burn warning..all of our noodles came out either in a clump or totally burned to the bottom of the pot and left all of our vegetables slimy. I would not recommend this “easy” recipe.
I did not have a problem with the noodles but found this recipe very tasteless. Cooked vegetables as instructed- they were raw! Turned the pot back on- they were mush. Had to make a peanut sauce to save this dish. I’m glad that it works for some people- just not us!
Hi Lee – Sorry to hear you did not enjoy the noodles. I am surprised the veggies did not cook well. I cut the broccoli to very small florets, so that it cooks with the heat of the cooked noodles. Glad you were able to salvage the noodles.
Hi Annie – Sorry to hear the recipe did not work for you. I have seen the newer models of instant pot are more sensitive to burn, which I believe is the potential reason for your getting the burn message. Can you please share what noodles you used?
This recipe never let me down so far, have made it more than 8 times and it’s so good. Thank you so much for sharing this recipe of yours .
I made this last night and it was delicious! I doubled the recipe and added extra of the veggies. I used 12 oz of chow mein noodles and the liquid to noodle ratio was perfect! I had to substitute sriracha for the red chili paste and fresh ginger for the ginger paste but it was still so yummy. I served it over arugula with pan fried tofu and it’s definitely a keeper. Thank you for the recipe.
Looks amazing! Could you use brown rice noodles with this recipe?
Hi Stefanie – I have not tried this recipe with brown rice noodles, so cannot say that it will work well.
What type of vinegar did you use
Thank you,
Daria
perfect, just love this recipe, never thot Hakka noodles in instant pot, your detailed recipe is too good. Tks for sharing
Has anyone ever tried this with chicken or shrimp? We have tried it as-is and enjoyed it but are not vegetarian and would appreciate the added protein.
Hi Katie – Glad to hear you have enjoyed the lo mein. To add boneless chicken, cut it into 1-2 inch pieces. Then saute the chicken in some oil for 1-2 minutes. The. follow the recipe.
Cooked up nicely & looked just like the pictures. However, lacked much flavor so if I make again, I will add more flavorings in sauce.
We tried it with lo mein noodles & doubled the recipe. Noodles came out a mushy & clumpy mess.. super disappointing, won’t try this again.
The taste was good . Exactly followed as recipe but the burn sign came on. Part of noodles were not cooked . I would increase the water if try another time. Probably depending on the type of noodles water content may differ. Used halka noodles and the 2 cups mentioned wasnt sufficient.
Hi Mich – Sorry to hear the recipe did not work well. You are right that different kind of noodles may need more/less liquid and cooking time.
Tried with spaghetti noodles….was delicious!!
