Fall is almost here and I am so looking forward to having more soups. There is so much eating out in the summer, that I want to just cozy up and enjoy healthy creamy soups all through Fall and Winter!

Cauliflower is perfect to make creamy soups, similar to potatoes. I also add cashews to make this soup even creamier. If you want to add more veggies to your diet, this is the perfect soup for you. Enjoy with toasty crusty bread on the side!

This vegetarian soup is so easy and quick to make in the instant pot. Come home after work, just add in the ingredients and let the instant pot make the soup, while you do other chores. This is one of the best Instant Pot Cauliflower recipes. Of course, the other awesome recipe is Indian Aloo Gobi 😉

I made this soup multiple times to shoot before posting, so I had some leftovers the next day. And guess what, I used the leftover soup as Vegan Alfredo Sauce for pasta, and it was so perfect. You have to give it a try!

Here is another vegan soup made in the instant pot that you will enjoy – Instant Pot Butternut Squash Soup. Check out this collection of 17 Instant Pot Vegetarian Soup recipes for more delicious soups!

How to make Cauliflower Soup in Instant Pot?

The process to make this Cauliflower soup is very straightforward. Heat the instant pot and sauté onions and garlic in some oil. Garlic adds an awesome flavor to the soup.

Then add the rest of the ingredients – cauliflower, cashews, turmeric, cinnamon, salt, and vegetable broth.

Pressure cook and then puree the soup using an immersion blender or a blender such as Vitamix. I prefer the immersion blender so I don’t have to transfer to another blender. I am also lazy to have to wash more things.

What spices to add to Cauliflower Soup?

You will notice that I don’t add too many spices to this soup. Yes, you don’t need to overwhelm your taste buds. A few basic spices and some lemon juice at the end are enough to make this your favorite healthy soup.

You can add more turmeric if you like, however, less is more in the case of turmeric. I have been making curries for a long time, and even though turmeric is an essential spice, it is added in very small amounts.

Garnish with parsley and red chili flakes. These are optional, but we love the slight spice from the chili flakes. Oh…and don’t forget the lemon juice. It is the most important ingredient to elevate the flavor of this soup!

  1. Used my Vitamix to blend. It is unbelievably creamy, flavourful and easy peasy. Used 3 teaspoons Knorr chicken bouillon powder with the 3 cups (boiling) water instead of salt. To me, the art of cooking is the seeking of Flavour. Brava! This recipe is absolutely delicious. Now I want to try more of your recipes. Thank you!

  2. This recipe is perfect just as it is written. I made tweaks based on my intense love of abundant spices. I increased most of the spices. I added nutritional yeast. I will make this recipe over and over! Thank you to pipingpotcurry.com!

  3. The soup has good flavor but disappointed that the cashews were still in whole pieces ( I did soak them in hot water for 1/2 hour before using them) when it was done. I did use the immersion blender but it was hard to find all of the cashew pieces.

    1. Hi Jodi – I would suggest to use a blender if your immersion blender was not able to grind the cashews to a smooth texture. I know it will be a little extra work with transferring and cleaning, but maybe worth it. Glad you liked the soup!

  4. I was excited to find this recipe since I had cauliflower I wanted to use up. I cook at all kinds of strange times in the evening and night (night owl with insomnia). So, last night I put everything in to my Instant Pot. I forgot that I had run out of lemon juice. I only had lime juice and I wasn’t prepared to risk ruining the soup. I was, however, able to put the soup through my blender this morning as it was cold. I added coconut milk instead of cashews. It wasn’t as thick as I had hoped it would be. I was a little disappointed though as I found the taste to be a bit flat (hence where the lemon juice makes a difference). I added salt, pepper, chives and shredded Tex-Mex shredded cheese. It helped. I will try this recipe again when I have lemon juice in the house.

    1. It’s not fair to rate a recipe less than 5 stars if you haven’t made it the way the recipe instructs, because it’s no longer the same recipe if you change it.

  5. Had a alrage cauliflower sitting there and getting less fresh. This recipe turned it into a wonderful soup. We loved it. Will definitely make again.

  6. “Mom, this one’s a keeper!” I love to hear this from my family! Wonderfully easy recipe with lots of flavour! I used a can of coconut milk instead of the cashews, and I used a chicken stock instead of vegetable. I didn’t get a chance to get the parsley before people started serving themselves out of the instant pot! I am definitely going to add this recipe to my regular rotation of soups. It’s such an easy way to get them to eat cauliflower!
