I first enjoyed a bowl full of the inspiration behind this tasty cauliflower soup recipe when we were vacationing in Nashville for New Year’s Eve.
Like many of the other recipes here on Evolving Table that were inspired by a restaurant’s dish, i.e. this Zuppa Toscana Soup or this Cream of Asparagus Soup, I quickly got to work recreating it as soon as I got home.
When I ended up making this cream of cauliflower soup…
not once,
not twice,
but FOUR times over the Christmas break… I knew I needed to share it with you!
Ingredients
For the exact measurements and detailed instructions, you can jump to the recipe.
- Head of cauliflower. Make sure you choose a medium-large sized head to ensure you get at least 5-6 cups of cauliflower florets.
- Onion. Sweet onions are ideal but yellow onions will work as well.
- Broth. Water and Better than Bouillon with a chicken base is the preferred option. If you cannot find it, simply swap it for vegetable or chicken broth.
- Red pepper flakes. Adjust the amount depending on how spicy you like.
- Seasonings. Salt, pepper, and dried sage add a nice flavor. Feel free to use dried basil, thyme, oregano, or rosemary in place of the sage.
- Raw cashews. These are ABSOLUTELY necessary to create a thick and creamy consistency without heavy cream. Do NOT get salted or roasted cashews.
How to Make Cauliflower Soup

- Wash and cut. Cut the head of cauliflower into bite-sized florets. It’s OK if they’re not all perfectly uniform, but you do want them pretty close to the same size. (Learn all the tricks for the best way to cut cauliflower!)
- Sauté the vegetables. Drizzle oil in a Dutch oven or large pot over medium heat. Add in the onion and cook for 5 minutes before tossing in the cauliflower florets. Continue sautéing for an additional 5 minutes then mix in the crushed garlic.
- Boil the soup. Pour in the broth, spices, butter or oil, and raw cashews. Bring everything to a boil and cook for 20 minutes. Remove from the heat and stir in the Parmesan cheese.
- Make it creamy. You can choose a variety of tools for this step. An Immersion (or wand) blender is super easy clean-up and does not require you to transfer hot soup into another appliance. A Vitamix or other high-speed blender is large and can hold all of the contents at once. Or, a food processor can be used, but you will need to work in batches to ensure everything gets super creamy.
Top and Serve
Garnish with fresh parsley and additional parmesan cheese. You can also pair with any of the following:
- Baguettes – amazing with a touch of butter and garlic!
- Homemade croutons – for those of you that like a bit of crunch.
- Parmesan cheese whisps – a great alternative to the above for those of you on a low-carb diet.
Meal Prep and Storage
- Prep-Ahead: The flavors get better with time, so completely make the whole recipe in advance!
- Storage: Bring it completely to room temperature then seal in an airtight container and refrigerate for up to 4 days.
- Freezing: Place in freezer-safe plastic containers and bring to refrigerator temperature first before freezing for up to 3 months.
- Reheating: Add to a pot over medium-low heat for 5-10 minutes, or pop a bowl of it in the microwave.
FAQs
Don’t forget the seasonings! Also, sauté the cauliflower, onion, and garlic to add a depth of flavor.
Blending raw cashews creates a thick and creamy consistency. If it is still not as thick as you’d like, you can stir in a cornstarch slurry.
Cauliflower contains both carbohydrates and protein. One cup of cauliflower contains 5 grams of carbs and 2.1 grams of protein.

Very delicious and easy to make.
Yay! So happy to hear you enjoyed the recipe, Kathy! I love how easy it is. Thanks so much for taking the time to leave a comment!
I thought this was a delicious soup! However, I changed out the spices a bit and added curry powder and cumin. Loved the flavor and it tasted even better the next day! Very filling and hearty but healthy too!
Yay! So happy to hear you enjoyed the recipe, Jessica! I’m glad you found a flavor combination you liked. Thanks so much for taking the time to leave a comment and rating!
I loved this recipe just as it is but my husband didn’t. I think this will make an excellent cream soup base for other additions like corn and even other veggies. For non-vegans chicken; clams or fish to make a healthier version of chowder might be good too. Have you tried any of these ideas?
I’m going to add corn and chicken to my leftover soup snd see if hubby likes it better.
Not yet, but those are all great ideas, Betty!! I totally understant the dislike from the hubby – my husband is also pretty picky when it comes to cauliflower but for some reason will gobble this soup up. Let me know if your other variations go well!
I have raw almonds on hand… would that be okay as a substitute for the cashews??
Almonds don’t get quite as creamy as the cashews do, but you can definitely try them out. You can also leave the nuts out completely!
Its November 2020 and fresh thyme has cauliflower jackets on sale cause they’re in season. So i bought a big one came across this recipe and made it. Most creamy soups mask flavors of the vegetables not this one the cauliflower shines so bright u can taste the sweetness of the cauliflower! I used the chicken broth and regular butter so it wasn’t a true vegan recipe but its all about what u prefer. I told everyone i know about this recipe and how delicious it is. I was hesitant about making this but once i did i was like that wasn’t to hard. I appreciate all the tips and options and video. Thank u 4 the guilt free recipe really enjoyed it and so did my family! 👍❤😁
Yay, Lisa! I’m so happy this recipe was a winner with you and the fam. And thanks for letting me know that the tips and video were helpful to you! Thank you for your comment and rating 🙂

Hi James! You’re so welcome! I do not have an exact serving size for this recipe, unfortunately. I would estimate it’s somewhere around 1 cup though. Hope you enjoy the recipe!
Okay so I love cream of anything soup but oh my goodness this looks amazing AND so easy to make dairy free! Can’t wait to make this with some delicious gluten free bread!
Yay!! Yes, it is SUPER creamy and crazy that it is DF. Can’t wait to hear what you think, Jules!
Could I use Cashew milk rather than the raw cashews? Maybe use less broth so it’s not too runny?
Hi Heather! In this particular recipe I would not recommend substituting the cashews. They definitely help to give the soup it’s creaminess!! However, let me know if you try it out. Thanks for the question 🙂
So delicious, can’t wait to make it again this week!
Yay!! I am so happy you enjoyed it so much 🙂 Thanks for the comment and rating!!
I even ate the leftover soup for breakfast…..twice! Love this soup!
LOL… You and me both!! It tastes SO good for leftovers 🙂
