What is vegetable lo mein?

Usually, the sauce is flavored with soy sauce, hoisin sauce, sesame oil, oyster sauce, and rice vinegar.

How to make Instant Pot Vegetable Lo Mein?
To start, grab a small mixing bowl and a whisk. Combine the soy sauce, hoisin sauce, oyster sauce, rice vinegar, and sesame oil. Set it aside.
Next, put the stainless steel liner into your pressure cooker and turn on the machine.
Set it to the saute function. Once it’s hot, add cooking oil, mushrooms, and onions.
Now, let them saute for a few minutes. When the veggies start to soften, toss in the garlic and let everything saute for another 30-seconds.
Then, turn off the machine and pour in the broth. After that, add the uncooked noodles.
Place the lid on the cooker and lock it into place. Make sure the valve is set to sealed.
Afterward, set the timer for 3-minutes on high pressure/manual cook. As soon as the timer goes off, carefully (using a kitchen towel) open the seal to preform a quick release.
At this point, you may have extra liquid in the machine. Drain the noodles and return them to the liner.
Otherwise, you’ ll end up with a bland, under seasoned lo mein noodle soup. Not very appetizing.
Last, pour in the soy sauce mixture and carrots. Turn the machine back on to saute and let everything cook for few minutes.
Once the carrots are soft, turn off the machine and serve the vegetarian lo mein.
That’s it, the Instant Pot vegetable lo mein is done! Kim and I hope you enjoy this recipe and wish you all the best 🙂
