This is a nutritious vegan riff on my childhood favourite, chicken noodle soup. Just as comforting but possibly even more flavoursome with a rich miso-based vegetable broth, lentils, diced vegetables and gluten-free noodles. This is a wonderfully comforting vegan soup and a great way to sneak in some extra veggies for the kids, especially if you're battling coughs and colds!

Isn't it wonderful how food can instantly take you back to a moment in time?
For me, one of the things I remember absolutely loving when I was a kid was chicken noodle soup. No, not the homemade healthy kind but the little packets of dried powder with pasta pieces and dubious little squares of “chicken” that you just add boiling water to and cook for 5 minutes. 🙈
I haven't tasted that packet soup for decades now but this veggie noodle soup is my healthier, vegan version that I like to make instead.
"Veganising" the old favourites
Before I went vegan, I used to make homemade chicken noodle soup for my family every time we had a roast chicken. It was a great way to use up the leftovers and it was an easy dish for me to serve, knowing that all the kids would eat it without a fuss. However, now I've gone vegan and I'm trying desperately to get the rest of the family to eat more plant-based meals with me, I'm slowly veganising all our old family favourites.
So, I decided to tinker with my chicken noodle soup recipe and try to make a tasty vegan "no-chicken" noodle soup alternative. I think I’ve exceeded even my own expectations and I’m thrilled with it. It ticks all the boxes and still tastes like delicious comfort food at its best. I hope you agree!
This soup is packed with veggies and healthy lentils for some plant-based protein so it's sure to perk you up if you're feeling in need of some vegan comfort food.
- Vegetables - onion, garlic, carrot, celery - together with mixed herbs, these vegetables are classic aromatics to provide the base flavour for your soup.
- Legumes - dried brown lentils - you can use tinned lentils if you prefer, in which case you can cut down the cooking time as they are already cooked. Just add the noodles at the same time as the tinned lentils, stock and herbs and just simmer for 10 minutes (cutting out the 20 minute simmer step before).
- Gluten-Free Small Pasta Pieces - I like to use the Schar little straight noodles (Capelli D'Angelo) or small round pasta pieces (anellini) as they are also vegan and are the perfect size and shape for this soup. If you prefer, you could also substitute with rice. Don't be tempted to use more than the recipe suggests though as it will take over the soup and dull the flavour.
- Vegetable Stock - the regular stock powder is fine for this recipe. I like Kallo or Marigold Bouillon Powder (paid affiliate link).
- Miso Paste - I like to use sweet white miso because I like its soothing, mellow flavour but you can use whichever one you like. Just check that it is gluten-free if this is important to you as sometimes miso is made from barley which is not gluten-free. My favourite is the Clearspring Sweet White Miso Paste (paid affiliate link) which is both vegan and gluten-free.

Although this is not necessarily a quick recipe, it is a very easy recipe! The basic method for making this vegan lentil and veggie noodle soup is:
- Fry the onion, garlic, carrots and celery.
- Add the lentils, stock and herbs and simmer for 20 minutes.
- Add the noodles and simmer for another 10 minutes.
- Stir in the miso paste and serve.
This is a summary only. Please see the printable recipe card at the bottom of this page for full instructions. Instant Pot and Thermomix instructions are also included in the recipe card.
- Be careful with how much pasta you add. It may seem like a small amount in the recipe but you really don't want too much pasta as it will dilute the flavour. Remember it is a soup not a bowl of pasta so you don't want the pasta to take over the soup. It expands a lot in the soup so it's hard to gauge at first when you're throwing the dry pasta in.
- Aesthetically, I think it is nice to have the vegetables all cut into neat little cubes that are in proportion to the size of the lentils and noodles. This also helps them to cook evenly (and quickly if small).
- If you want an even more "chickeny" flavour, you could try using the no-chicken vegan chicken stock powders (paid affiliate link) that are now available!
- Try to brown the vegetables when frying in the oil so that they get some of that deep caramelisation that adds depth to the soup. To do this, you will need to make sure you don't stir it too much as it needs to have contact with the hot pan for long enough to brown before you stir.
- I add the miso paste at the end of the cooking time to preserve the fermented goodness as much as possible. Fermented foods are so good for us so I like to use them as often as I can in our family meals.
Any leftovers can happily sit in the fridge for a few days. However, the noodles will continue to absorb the liquid so you may need to add a little more water or vegetable stock when you re-heat the soup.
If you're planning to make this ahead, then don't add the noodles and when you come to heat it up for serving, just cook the noodles in the soup for 10 minutes and then stir in the miso at the end.
Vegan Noodle Soup FAQs
Yes! This vegan noodle soup is very easy to make in the Instant Pot! (paid affiliate link) I have added specific Instant Pot instructions to the recipe card below. Essentially it is as follows:
- Sauté onion, garlic, carrots and celery until browned (5-10 minutes).
- Add lentils, stock and mixed herbs. Lock lid and set to HP for 10 minutes.
- Quick pressure release, stir, add noodles, lock lid again and set to HP for 2 minutes.
- Quick pressure release, stir in miso paste and serve!
Yes absolutely! I have added Theremmix instructions in the printable recipe card below. The basic TM instructions are:
- Roughly cut the veggies into chunks. Add to the TM jug with the oil and set to 3 secs / sp. 5.
- Scrape down the sides with the spatula and set to 6 mins / 120•C / sp. stir.
- Next, add the lentils, stock and herbs and set to 20 mins / 100•C / Rev. sp. 1.
- Then, add the noodles and set to 10 mins / 100•C / Rev. sp. 1.
- At the end, stir in the miso paste with a spatula until melted and distributed evenly throughout the soup.
Lentils are a great wholefood ingredient for this soup but if you don't like them, you can substitute with chickpeas or beans or even with tofu or vegan chicken pieces (watch out for gluten in the commercial vegan chicken pieces though)!
This recipe is a healthy vegan alternative to chicken noodle soup, perfect for when you're not feeling well. If you want to make it even more like chicken noodle soup you could use vegan chicken pieces instead of lentils and you can use vegan chicken stock powder instead of vegetable stock.
The Instant Pot instructions for this recipe were created in the Instant Pot Duo (paid affiliate link) and should work in the same way with all pressure cookers that allow you to manually set your own pressure cooking time. Please check the user manual for your own Instant Pot.

- To cook with tinned lentils, just skip the 20 minute simmering and combine steps 4 and 5 so that you add the tinned lentils together with the pasta pieces and stock and herbs, and simmer for 10 minutes only.
- If you are making this soup ahead of time, do not add the pasta as it will absorb all the liquid and go mushy. Instead, add the pasta at the time of re-heating and cook for 10 minutes when re-heating, to ensure the pasta is cooked.
- Store in a sealed container in the fridge for 3 days but if the pasta is included, you may need to add more stock on re-heating.
