What is Lo Mein?
Vegetable Lo Mein is an Asian stir fry recipe made with boiled noodles, veggies and sauces. Sometimes Lo Mein is also referred to as chow mein.
Chow mein is made with crunchy noodles that are fried and then added to vegetables and sauces.
What is usually in vegetable Lo Mein?
The main ingredient to make Lo Mein is noodles, vegetables and sauces. I have used spaghetti noodles to make this recipe.
Vegetables like carrots, baby corn, mushrooms, colorful bell peppers, snow peas and broccoli can be used. The best part of making Lo Mein at home is that you can add or omit vegetables as per your preference.
Soy sauce, chili sauce, and optionally some sriracha sauce is added to give it the savory and spicy flavor. Finally, this delicious Lo Mein is garnished with some green onions.

What type of noodle is Lo Mein?
You can make Lo Mein with any type of noodles at hand. I prefer to use the spaghetti as my kids love it. However, linguine, fettuccine or Hakka noodles will work too.
Why make Lo Mein noodles in the instant pot?
The simple answer is convenience. It completely does away with the tedious step of boiling, monitoring and draining water for cooking the spaghetti.
It is almost a dump-and-go, one-pot meal with zero-minute pressure cooking and is ready in under 30 minutes without any supervision in the instant pot.

How to make vegetable Lo Mein in instant pot?
To make Lo Mein, first turn the instant pot 'saute' mode on. Once the instant pot is hot, add sesame oil followed by garlic, ginger, and green onion whites and sauté them for few seconds.
Turn the instant pot off by pressing cancel. Add water, chili sauce, dark soy sauce, salt, and sugar. Deglaze the pot with a spatula.
Now break the spaghetti into half and place them in 3-4 criss-cross layers. Gently push the spaghetti under the liquid with the help of a spatula. Layer all the vegetables (except broccoli) on top of the spaghetti and lock the instant pot lid.
Turn the instant pot pressure release knob in the sealing position and cook on high-pressure mode for 0 (zero) minutes with the keep warm setting turned on.

Instant pot will come to pressure and then go into keep warm mode. Allow the pressure to release naturally for 6 minutes and then turn the pressure knob to venting position and manually release all the remaining pressure until the silver pin drops.
Open the lid and mix in frozen broccoli (thawed). There will be some liquid but as you mix the spaghetti noodles, the water will get absorbed.
Gently mix everything with the help of kitchen tongs and loosen up the spaghetti if needed. Garnish with green onion greens.
If you are using fresh broccoli, cover the lid for about 2-3 minutes and the heat will be enough to cook them tender.
How to store vegetable Lo Mein?
Vegetable Lo Mein can be stored in the freezer for about a month. You can also refrigerate any leftovers. So, you can always plan ahead and make them for later.
When you are ready to eat simply thaw and heat the frozen Lo Mein noodles in the microwave and spice it up with any sauces if needed.

How long does vegetable Lo Mein last in the refrigerator?
Vegetable Lo Mein can be stored in the refrigerator for 3-4 days. It tastes fresh after reheating and does not become soggy. So, you can always plan your meals ahead and make it ahead of time for meal planning.
How do you reheat leftover Lo Mein?
If you have stored your leftover Lo Mein in the instant pot liner in the fridge, you can simply reheat the Lo Mein noodles in the instant pot. Turn the 'saute' mode on and heat the noodles for 2-3 minutes depending on the quantity.
Also, stir the noodles in between with kitchen tongs to ensure it does not stick to the bottom of the instant pot.
You can also reheat the leftover noodles in the microwave or stovetop. When reheating the vegetable Lo Mein in the microwave, depending on the quantity, heat it for 1-2 minutes and then mix it evenly to distribute the heat.

Wonderful so easy, one pot makes easy clean up. Have added sautéed shrimp or crumbled salmon both w greens when finished. My only question is why do I keep having extra liquid in bottom of pot?

Hi Kimberley,
Glad you liked the recipe. The extra water is because of the veggies, as they cook they release some water. Once you mix up everything with the tongs, it will get absorbed.
Hope this helps.
Cheers,
