Time for  some Cauliflower Kale Soup.

You can definitely tell it is fall around here.

Even though the temperatures were in the 70s this weekend, I’m getting excited about trees turning yellow.

It is time for some comfort food and soups are perfect for this time of the year.


A while back I used to make soup almost every day.

And I need to get back to this routine. I’m all about quick and easy soups that are usually make in less than 1 hour.

You have a huge cauliflower fan here – that’s me!

I also had some readers requesting a kale recipe and I’m excited to share this Cauliflower Kale Soup recipe with you today.

Why roast the cauliflower?

You can definitely steam or boil it and this will save you some time, but the taste of the soup will be a little different.

Why do I prefer roasted cauliflower in most of my soups?

Roasting the cauliflower intensifies its flavor and gives it a slightly nutty taste. It is all about flavor. You can also use roasted cauliflower as a side dish or in rice and quinoa bowls. It is not mushy like boiled (or steamed) cauliflower and has a great texture and even a little crunch. That’s why this Cauliflower Kale Soup tastes so good!




Kale and cauliflower is a nice combination.

In this recipe half of the kale is roasted to make crunchy kale chips and the other half is boiled and then pureed in the soup.

Kale is a superfood, which I use for soups, salads and smoothies.

It is nutrient dense food, rich in vitamins, minerals, it contains fiber and it is low in calories.



You can definitely serve the soup without even pureeing it, but I just love cream soups and that’s how I make it.


The recipe is for a small batch of 4 servings, because we (my husband mostly!) usually don’t like left over soup.

  1. Wonderful recipe!  You don’t like leftover soup?  Soup always tastes better the second day!  And I always freeze leftover soup to have one night in the future when I don’t feel like cooking. 

  2. This was a wonderful beautifully colored soup! I loved that it did not have dairy in it. The only thing I would say is that the cook timing is off The cauliflower and kale alone roast for 55 min,, so the total timing threw me. It was worth it for these super foods, but I will allow more time. Thank you for this wonderful recipe. I use an oven roasting pan, porcelain on steel ,rather than foil for good health.

    1. Thank you Linda! U’ll add a note for the time. I usually roast them together in the oven, (one pan on top of the other and rotate them), to save time.

  3. This soup is so yummy! I made it as you have posted (except I scaled down for one serving; didn’t want leftovers if I didn’t like it!). I will definitely make this again! Thanks for posting it!

  4. Hi Mira, first of all thanks for sharing the wonderful and lovable cauliflower soup! I am going to try this and I wish it would be yummier than this.. 🙂

  5. I love this recipe! It’s a perfect way to get my kids to eat healthy and still enjoy it! I’m hoping to add spinach to the recipe as well, any idea how that would effect the recipe? Thanks!
