The result of blending this cauliflower kale soup is ideal. The flavor is lusciously creamy and delicious with every spoonful. Topped with some crispy kale chips adds a satisfying crunch. It’s so tasty, this soup surprisingly proved to be a winner, even to my most reluctant eaters.

Today it’s bitterly cold outside, so I decided to revive this recipe from our archives. It’s always a good time to break out the Dutch oven or a large pot and get cooking!  Our family loves a pot of soup on the stove.

Vegetable soups are good for everyone, especially the ones filled with nutrients to help boost the immune system. That fact alone makes this recipe a perfect dish to serve your family this time of year.

I must confess that when I came across this recipe in a magazine, I was a little skeptical at first to try it, but my instincts told me to go ahead and experiment.

But the result took her by surprise, and actually, took us all by surprise!  So much so that we all had 2 bowls of this delicious soup

The bonus topping of crunchy kale chips is what made this soup even more sensational.

How to Make this Cauliflower Kale Soup with Crunchy Kale Topping? 

This pureed cauliflower soup recipe is one of those easy soup recipes you can pull together in 50 minutes, from start to finish.

3. Add the Broth, Cauliflower, and Kale: Next, pour in the broth, and add the roasted cauliflower and fresh baby kale. 

4. Simmer: Simmer the soup on low heat for a few minutes, about 10 minutes.

5. Next, Make the Kale Chips:  Reduce the oven temperature to 300. On a large baking sheet, scatter half the kale onto a baking sheet, sprinkle with salt, and drizzle with extra virgin olive oil over the kale. Roast for 10 to 20 minutes.

How to Make Crunchy Kale Topping?

Just toss the kale loosely on a pan with a drizzle of olive oil and some salt, and bake until it becomes crunchy.  Then sprinkle a few kale chips on top of each soup before serving.

And I have to give you some warning! These kale chips turned out so good, I had to make a second batch immediately because my daughter and I couldn’t stop eating the first batch as soon as they came out of the oven.  Haha!

They are THAT good!  And, they turn out very light and practically melt in your mouth. Kale chips will make the perfect snack too!

Tips about Cooking Cauliflower:

  • Every time I mention cooking cauliflower, the most asked question arises: Is there a way to prepare cauliflower to prevent that terrible smell?  The answer is Yes! There are better options for cooking cauliflower.

  • First, don’t steam or boil it.  Rather, roasting or sauteing cauliflower is the best way to go to prevent that stinky stench.  

  • Also, when you add olive oil and fresh garlic to the cauliflower and even some herbs, results in a pleasant aroma, making your house smell wonderful.

Best Way to Store Leftover Soup

Always transfer the soup to an air-tight container, and keep it chilled in the refrigerator. It will stay fresh for up to 4 days.

Can We Freeze This Soup?

Yes! Always allow the soup to cool down completely. Then transfer cooled soup to your freezer containers or bags. We prefer to mark them with a date on the container and place them in your freezer. It should last frozen up to 3 months.

To thaw the soup, allow the container to sit out on your counter for a few hours. To thaw quicker, allow the container to sit in a bowl filled 1/2 with hot water.

  1. Hi – So glad to hear Kathy! It is so good and we make it often. Keep in mind the color will vary by the amount of kale blended. Sometimes I add in more kale and the soup is greener, the taste is always delicious- enjoy!

    1. We have too! And never thought about combining the two but it's truly amazing! You have to try it Cheri, we think you'll love this one.
