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 for making 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 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 too 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. Fantastic! Everyone loved the cauliflower soup! … and I forgot to add lemon. I doubled recipe. Will make again soon — 4X maybe!

    1. Hi Dolly – You can skip the cashews. Some options are coconut milk or cream, but this soup could work without any additions too. I hope you enjoy it!

  2. A friend asked me if this recipe could be made on the stovetop. She doesn’t have a pressure cooker. How would you adjust this recipe to make it on a stovetop or in a Le Creuset on the stove?

  3. I didn’t know what to expect from this recipe, but I liked the fact that it was made in the Instant Pot and had few ingredients, all that I had on hand. This recipe was wow, so delicious! This will be on my rotation for chilly fall/winter evenings! I may give the leftover idea a try, too, serving it as a vegan creamy Alfredo sauce over pasta! Thanks for this great (and easy) recipe!
