Super rich, insanely creamy Instant Pot Tomato Soup. Made with canned tomatoes for convenience, it's really quick & easy to make & involves minimal washing up. Dinner win!
I am totally that girl who loves a piping hot bowl of soup when it's chilly out and aside from my Instant Pot Red Lentil Soup, this Instant Pot Tomato Soup has got to be my all time favourite. I absolutely adore my Easy Tomato Basil Soup, but it's made using fresh tomatoes and I don't always have enough on hand to make it. However, I do always have a can of tomatoes which means that I can make this Instant Pot Tomato Soup at the drop of a hat.
Add to that the convenience of using an Instant Pot and it's now my go to quick and easy dinner, perfect for when your fresh produce selection is looking pitiful and you really can't be bothered to go shopping.
Make some of my No Knead Focaccia Bread to accompany it, maybe some golden and crispy vegan croutons and you can have a super easy, tasty and hearty dinner on the table in no time!
If you don't have an Instant Pot don't worry, because I have included stove top directions too!
I am quite literally obsessed with my Instant Pot (<<< affiliate link) in case you haven't noticed:
A slow but steady stream of new Instant Pot recipes are appearing here and I think that it's a trend that will continue because this little appliance makes my life so much easier. 
One pot, no watching, no having to stir. Just throw it all in, walk away and forget about it. It even keeps the food warm if you forget about it or aren't ready to eat. Busy Mom win!
How to make Instant Pot Tomato Soup
This Instant Pot Tomato Soup is made using simple ingredients and is extremely low effort.
You start by sautéing the onions and garlic right there in the Instant Pot. No extra washing up is going on here today! Then you quite literally throw everything else in, give it a quick stir and cook on high pressure for 7 minutes. Let the pressure release naturally, then blend it up until silky smooth.
I like to blend mine in my Blendtec blender (<<<affiliate link) because it makes the soup incredibly smooth and creamy.
If you have one I highly recommend the extra step of ladling out the soup and blending it in batches (it won't all fit in one go). If you don't though, a stick blender right there in the Instant Pot will do a good job and save you a bit of cleaning up.
This is why I am loving this Instant Pot Tomato Soup:
- It's so easy!
- It's super thick and creamy
- No oil is necessary
- It's healthy and low in calories
- Everyone likes tomato soup (no arguments at dinner time!)
- It freezes well and leftovers reheat perfectly

Instant Pot Tomato Soup
Author:
Ingredients
- 1 medium onion chopped finely
- 4 cloves garlic , chopped
- 796mls / 27oz / 3⅓ cups canned crushed tomatoes , or passata
- 156mls / 5.5oz / 1 heaping ½ cup tomato paste , NOT sauce or ketchup (tomato puree in the UK)
- 2 teaspoons salt
- 70g / ½ slightly heaping cup raw cashew nuts , not roasted
- 1 tablespoon dried basil
- 1 teaspoon dried oregano
- ½ teaspoon black pepper
- 1 -2 tablespoons sugar *
- 1200mls / 5 cups water
INSTRUCTIONS
INSTANT POT INSTRUCTIONS (My Instant Pot is a 6 quart. If yours is a different size you will need to scale the recipe up or down accordingly).
- Saute the onions in a couple tablespoons of water in the Instant Pot. Once starting to go golden, add the garlic and cook stirring frequently for another minute then turn off the Instant Pot.
- Add all of the other ingredients. Put the lid on and seal the vent. Set to high pressure for 7 minutes then allow the pressure to release naturally.
- Transfer soup to a blender and blend until smooth, or use a stick blender in the Instant Pot (the soup will be creamier if you use a blender). Return to the Instant Pot. If you prefer a thinner soup, boil some water in a kettle and add it gradually until you get the thickness you like. Check seasoning and add more salt, pepper or sugar if necessary before serving.
On the stove top
- Saute the onions in a couple tablespoons of water in a large pan. Once they are starting to go golden, add the garlic and continue to cook for another minute.
- Add all of the other ingredients and cook over a medium heat for about 20 minutes, stirring occasionally.
- Transfer soup to a blender and blend until smooth, or use a powerful stick blender in the pan (the soup will be creamier if you use a blender). Return to the pan. If you prefer a thinner soup, boil some water in a kettle and add it gradually until you get the thickness you like. Check seasoning and add more salt, pepper or sugar if necessary before serving.
NOTES
- Sugar brings out the flavour of the tomatoes and really helps the overall flavour of the soup. I like to use 2 tablespoons in this recipe. If you aren't sure add 1 tablespoon at the beginning, then taste when cooked and add another tablespoon if necessary.

Valerie says
Can I sub fresh uncooked tomatoes & if so what amount/weight?
Melanie McDonald says
The recipe has only been tested with canned crushed tomatoes so I don't know how that would work out. If you want to try using fresh tomatoes use exactly the same amount. You will probably need to adjust the amount of water added too, but as I've never tried it I can't advise how much. You'll just have to wing it.

Erin says
You specified raw cashews and *not* roasted. Can you explain why? We only have roasted cashews on hand (and are limited to these specific cashews because of our daughter's other nut allergies), so I wondered what ramifications would be of using them in this recipe. Thanks so much!
A Virtual Vegan says
Raw cashews are softer and blender smooth more easily because of that. They have a more neutral flavour too. If you've got a great high-powered blender you could probably get away with using them in this soup though.
Erin says
Thank you! I really appreciate your response!
Martha says
Wonderful soup and so easy and quick to make. I love it and even my non-vegan, finicky eater husband likes it too!
Anna says
This was so delicious and easy to make - definitely a keeper. I made this with vegan grilled cheese sandwiches. Thank you so much for the recipe!
Pete says
This is our families favorite recipe! I’ve made it maybe 10 times and it keeps getting better! I add a can of Hatch green Chiles and it is great. You French Toast is also a favorite
Melanie McDonald says
Thank you Pete! I'm really pleased you're enjoying it. This and the French toast are favourites of mine too!
Dianna says
Best tomatoe soup ever IMO! I added 2 grated carrots leftover from another recipe, and only used 4 cups of water for a little thicker soup, but otherwise did everything as directed and it was rich and satisfying with wonderful flavor. Thank you for this recipe!
Aileen says
Absolutely fabulous, I can’t believe we have tomato soup back in our life! Many thanks. I added nutritional yeast to each bowl and it was beyond delicious.
A Virtual Vegan says
Thank you. I'm really pleased you enjoyed it!
Liz says
Just made this soup and it was FANTASTIC!!! Thank you! I included the 2 Tablespoons of sugar. It was perfect and really easy to make!
A Virtual Vegan says
I'm really pleased you enjoyed it Liz! Thanks for taking the time to come back and leave a rating/review!
Michelle says
Any no but subs for cashews that would work?
Michelle says
I mean no nut subs, good grief
A Virtual Vegan says
Ha ha! Your typos are as bad as mine. Hemp seeds work well as a sub for cashews in recipes like this. If you don't have any though you could use 1.5 cups less water to cook the soup with, and then once its cooked, add 1.5 cups of creamy plant-based milk or light coconut milk from a can (it must be light so the soup doesn't taste of coconut)and just let it simmer for a few minutes until heated through again.Hope that helps!
Karen says
Make this recipe in an attempt to recreate a lunch at a local plant based café. My husband gave the Instant Pot Tomato Soup a thumbs ups, which means it will become a staple recipe in our rotating menu. Did not have tomato paste in our pantry, so substituted tomato puree and it worked fine. Blending it in the Vitamix really thickens the soup. Great recipe!
Jennifer says
I made it tonight! My husband and I loved it! My daughter (6) does not like canned tomato soup but said she liked this! This may have just made my life easier some nights when I make this! I’m looking forward to wasting it for lunch tomorrow!
Jennifer says
I meant eating it tomorrow!
A Virtual Vegan says
I'm really pleased it's a hit with your family. Enjoy your lunch tomorrow!
Justin says
This soup was incredible! Being fairly new to eating vegan, we’re still experimenting with new and different foods and recipes. We’ve tried a pretty wide variety and have really struggled to find things we love. THIS was it for us! Thank you so much for posting this recipe!! It’s by far our favorite!!
A Virtual Vegan says
I'm really pleased you enjoyed it Justin. It's a favourite of ours too!
Judie says
Very good. Creamy non-dairy tomato soup. Easy to make. I froze a few single serving size bags so I can just take a bag from the freezer and enjoy this soup on a cold winter day. I may soak and blend the cashews with some of the water and then add it to other ingredients next time I make it, so I don't have to blend at the end.
Diana says
Indeed a tasty soup made just as recipe reads however I would prefer a creamier soup and will increase the amount of cashews or perhaps potatoes. I added some cooked chunks of potatoes, carrots and onion to this finished soup and paired it with a crusty bread for deliciousness I shared with friends and coworkers.
