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 potato. I also add cashews to make this soup even creamier. If you want to add more veggies in your diet, this is a perfect soup for you. Enjoy with a 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 recipe. 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 - Thai 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 dont need to overwhelm your taste buds. A few basic spices and some lemon juice at the end is enough to make this your favorite healthy soup.

You can add more turmeric if you like, however less is more in 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 less quantity.

Garnish with parsley and red chili flakes. These are optional, but we love the slight spice from the chili flakes. Oh...and dont forget the lemon juice. It is the most important ingredient to elevate the flavor of this soup!

    This is so delicious! I followed the recipe completely, even though I skeptical of the cinnamon. Maybe a little extra garlic. Also added red pepper flakes before blending the whole thing. And added the optional lemon juice. Just amazing and I will be making this again all winter!

    Tried this today and it’s a winner. I had a few small red potatoes laying around so added them, which made it thicker so had to add an additional cup of stock, but the flavor is out of this world and its so quick and easy. A*

    This soup is just lovely. It has a pretty lemon color, a thick, creamy texture and a beautifully fragrant aroma. My vegan daughter said, "Great soup, mom!" and my meat-loving son said, "Mom, this is the best soup you ever made!" He "called" the left-overs for lunch tomorrow. 🙂

    Can you freeze this soup?

      Hi Mary - I think this soup will freeze really well. Let it cool completely and store in small portioned airtight containers for up to 2-3 months in the freezer.
