How to make roasted cauliflower soup
This rich and creamy roasted cauliflower soup may not be the quickest dinner to make, but it is extremely easy! The veggies are roasted in the oven while you prepare a simple roux on the stove. When the two are pureed together, you end up with an incredibly rich and simple meal!
Here’s how it’s done:
Evenly spread the cauliflower florets, carrots, and garlic across a rimmed baking sheet. Drizzle olive oil over top before seasoning the veggies with salt, pepper, and nutmeg. Gently stir to coat.
Roast the vegetable medley until they’re tender and fragrant. Once they’re done, remove them from the oven and set aside.
In a large pot, create a roux by cooking the butter and flour over medium heat. Once a paste has formed, add the chicken broth and milk and continue to cook until slightly thickened.
To the creamy roux, add most of the roasted cauliflower florets, carrots, and garlic. Use an immersion blender to puree the veggies until the soup is creamy.
Add the remaining veggies to the soup and give everything a good stir to combine. Serve warm and enjoy!
Tips and variations
- Gluten free – Swap the all purpose flour for any other gluten free flour you like.
- Vegan – You can use vegan butter or olive oil instead of butter, dairy free milk instead of regular milk, and vegetable broth instead of chicken broth to turn this into a vegan roasted cauliflower soup
- Keto – Carrots are typically avoided on keto diets because of the high number of carbs. Feel free to swap them for another keto-friendly vegetable, like broccoli or more cauliflower. Also, make sure to substitute the all purpose flour for cassava flour, arrowroot starch, or a 1:1 gluten free flour blend.
- Add more veggies – Try adding roasted potatoes, asparagus, squash, bell peppers, kale, or spinach to this creamy soup.
- Toppings – I like topping each bowl with a drizzle of olive oil, some croutons, or even a handful of crumbled bacon.
- Super smooth – If you prefer an ultra-smooth soup, go ahead and puree all of the veggies together. If you don’t have an immersion blender to do this, use a regular blender and puree the soup in batches.
How long does it last?
Leftover roasted cauliflower soup will last for up to 4 days when it’s stored in an airtight container in the fridge. Just be sure to let the cooked soup cool before storing!
Can you freeze cauliflower soup?
Yes! To freeze, allow the cauliflower soup to cool down before transferring it to an airtight container or ziploc bag. Cauliflower soup can be frozen for up to 6 months.

Great flavor but didn’t need the roux, made my soup ultra thick like a paste; ended up adding twice the liquid, and also garlic, it and was still very thick. Would be helpful to quantify # cups of cauliflower in addition to the carrots. I made mine with a large head of cauliflower from a farmers market. Thanks for the recipe.

Hey MCS, glad you liked this soup recipe! I make this all the time and never had the problem of it being too thick. Common problems with a too thick roux is that too much flour was added, all the ingredients were added at once or there wasn’t enough whisking – maybe try those next time when making? Thanks again for stopping by!
Norma says
The recipe is quite good. I withheld a star because I do not have a sous chef. But the flavor is very good I added additional chicken broth because I like my super little thinner and I added smoky paprika because I like a bite.

I made this soup yesterday! This was a major accomplishment that I had planned for several days, seeing that we were having a fridge delivered on same day.
Soo got my veggies ready,carrots chopped ,onions chopped, cauliflower in florets, garlic. Oh check recipe. OMG, there are no onions!!! OK so first mistake. Put the tray in oven. After about 15 minutes I am like what is happening? All my veggies are getting so dark. So re read the recipe. I had cut veggies way too small, so I turned off the oven and let them sit. Which turns out was a really good idea. I made my broth at that time, and after it was ready, I put veggies in after picking out some of the darker bits of onion that should not have gotten in that tray.Let everything cook while I was getting my new fridge set up and going.
So I will tell you that even with the mistakes I made this soup was phenomenal!!! Absolutely delicious and it was so welcome after a crazy day. Even with the mistakes I made to start with, I ended up with the tastiest soup I could hope for.

Soup is just what the doctor ordered sometimes and yours is indeed slurp worthy!! I love how healthy it looks and the cauliflower sounds like it would taste amazing after roasting. Sprinkle of nutmeg – you go girl, that sounds perfect!

Thank you for this great idea. I make pumpkin soup the same way, roasting the vegetable first but never tried with cauliflower. Sounds like a great idea and will try this week
