Quick and Easy Vegan Noodle Stir Fry

I have a love for sweet and sour dishes and they appear here a lot!

Check out my sweet and sour chicken balls, sweet and sour prawns, sweet and sour salmon, sweet and sour pork chops, and sweet and sour tofu recipe to name check a few.

My latest option is delicious and easy vegan sweet and sour noodles.

This is proper food in a hurry territory, a leisurely 10 minutes of prep is followed up by around frantic 5 minutes of cooking.

It has a darker less saccharine sweet and sour sauce which I love, and it coats the thick udon noodles perfectly.

I’ve begun using udon noodles a lot recently, they feature in everything from my yaki udon recipe to my take on yakisoba pan, which is essentially a noodle sandwich.

Whether you eat this dish as a light meal or an easy side dish, you’re gonna love it.

Frequently Asked Questions

Can I use a different type of noodle?

Yes, this recipe has evolved to use udon noodles fairly recently, but I made it for years with egg noodles. I usually use wholewheat gee noodles, the same type that I feature in my ginger pork stir fry.

Naturally, if you shift to egg noodles this dish will not be suitable for vegan diners.

Another option is rice noodles, I have to say that they are far from being my favourite. However, they can be switched into this recipe very simply. Go for rice noodles that are quite large “fat”.

What is Shaoxing wine?

Shaoxing is a rice wine, I use it a lot in my Chinese fakeaway recipes, you could use any rice wine. Many say to use dried sherry as a substitute for this but I find gin makes a much better option.

What is Chinkiang vinegar?

Chinkiang is a Chinese black rice vinegar and I love the stuff! It has a bold and complex flavour, you could use other rice vinegars if you wish.

Do I have to use MSG?

No, you can omit it if you like, but you will be missing out on a big flavour boost!

Serving Suggestions

I will often serve this dish as a pretty light lunch dish on its own, however, it also makes a superb side dish.

I’m particularly fond of serving it with char siu pork tenderloin or even char siu chicken. It’s also wonderful with my Chinese pork belly.

If you are hunting for something vegan, how about this blackened tofu steak?

This also pairs really well with salt and pepper dishes, you could rock some salt and pepper tofu, salt and pepper prawns or even salt and pepper squid.

  7. Cut the spring onions into rounds as thinly as you can keeping the white parts and green parts separate.
  8. Drain the tins of water chestnuts and bamboo shoots.
  9. Heat a wok over a fiercely high heat and when it is shimmering add the oil, then quickly add the onions and carrots, then stir fry for 2 minutes, keeping the vegetables moving all of the time.

  11. Add the garlic and ginger, then stir fry for another 30 seconds.
  12. Pour in the sauce that you made in step one and cook for a minute, or until it begins the thicken.

This is such a delicious looking dish Brian, I love all those beautiful flavours you have in here - I have, however, never heard nor used the Chinkiang Vinegar before - will definitely make a note of this to try it. It sounds good - I could bathe in vinegars so need to try this too, ha ha. Thank you for sharing this delicious sounding and so gorgeous looking recipe ;-)

Chi9nkiang is a glorious Asian black vinegar... In some ways it is similar to Balsamic but not as complex or rich in flavour, for me it is the very best for sweet and sour sauces.

Sounds so yummy!! I have never heard of Chinkiang Vinegar before?! I will keep an eye out for it! And I need to have some gin on hand too! I love how quick this would be to whip up and it seems like to would be filling too without hassling over chicken or beef! Love it!

Always so important to have Gin available, just for the food obviously ;) Chinkiang vinegar is an Asian fermented black vinegar, in a similar way to balsamic being a fermented black vinegar, the flavours are very different though.

Oh Brian! I too love a bish bash bosh tasty meal lol! My pantry is always loaded with various sorts of noodles as I love noodles stir fries, I love the hot hot ones, the coconut ones, haven't tried sweet and sour yet, pinning your recipe for later, thanks!

I love sweet and sour, get the balance right and they are my favourite flavours in food!

Great recipe, It reminds me of London when I used to work in the City coming back at midnight and the only place open was a Chinese takeaway. I love sweet and sour, but I never tried the Chinkiang Vinegar. I will keep my eye open next time I am at ta Asian supermarket. Also, love the flexibility of using any fresh green available.

I've come home from work late many a time and only found takeaway restaurants open... Definitely part of my reason for killing off the so-called 9 to 5. Chinkiang is a fermented black vinegar and is great for Chinese food!
