Roasted Cauliflower Soup Recipe

By  | 

It is hard to believe fall is already creeping up on us! I’m glad and sad, all at the same time! Glad to move on to the next season, to get back to a regular schedule, and for the crisp autumn air. Sad because winter is coming. In MN, winters are rough. I’m sure other parts of the country are as well. But, doesn’t it sometimes feel like your part of the world must have the worst winters ever? It sure does here in MN. But, one of the great parts of cooler weather is soup. We adore soup here. And, this roasted cauliflower soup is a favorite! Warm, hearty, tasty, and easy to make! Best of all it’s gluten-free for those that need that option! Besides my cauliflower potato salad, it’s my favorite use of the tasty white veggie!

This Roasted Cauliflower soup recipe is easy to make and so delicious!  soup, soup recipe, gluten-free, gluten-free soup, cauliflower

I would love to give you a great family history about this cauliflower soup. But truthfully, growing up we didn’t eat much soup. Macaroni and cheese (hey-try this cauliflower version!), tuna melts, fluffernutters, and boxed cereal were much more the speed of our big family. They were fast and easy for us children to make for the whole family. But, we now love making homemade soups with farmers market finds or herbs from Levi’s little garden. Someday we imagine our kids making giant batches of soup in the winter and bringing some over for us! Yum!

Roasted Cauliflower Soup

  • 1 head of cauliflower, rinsed and chopped.
  • 2-3 cloves of garlic, minced.
  • 1-2 tablespoons of butter
  • 1 onion, chopped finely
  • 1 1/2 cups chicken broth
  • 1/2 cup water
  • 1 bay leaf
  • 1 teaspoon finely chopped thyme leaves
  • 1 cup heavy cream
  • parmesean cheese (for serving)

1. Mix the chopped cauliflower  with the minced garlic and put it on a cookie sheet. Drizzle olive oil on it and place it into a pre-heated 450 degree oven for about 20 minutes. Be sure to stir it once or twice so it doesn’t get black and nasty on the bottom.

2. Put the butter into your med/large soup pot and melt it. Add the onions and cook them up until nice and golden. About 10 minutes.

3. Add the chicken broth, roasted cauliflower, herbs, and water to the onions. Simmer on low for about 30 minutes or the cauliflower is very tender.

4. Stir in the heavy cream. Heat the soup back up again.

5. Use a blender or immersion blender to puree the soup. We sometimes skip this and eat it in broth form. It’s still delicious!

    Do you have another cauliflower soup recipe? I have this pinned on my board but the picture it shows is not the one listed above? I ask because I made this amazing cauliflower soup last winter and I can not find the recipe. It looks like the picture I have pinned but this recipe it takes me to is not it.

    It doesn’t have to be cold for me to appreciate soup. I have mentioned before – at least once or hundred times how much I hate winter- so I’m NOT looking forward to snow. I can take cold — it’s that ugly slushy icy stuff that gets to me. I will wait for you to post pictures of scenic snow covered landscapes and I will appreciate them toasty warm :-) I am glad you discovered cauliflower. I love it any which way — including smashed.

      You are a smart woman, Marisa! We will be sure to post lots of photos that make winter seem wonderful and beautiful (even though usually it is awful!!!). And then you can enjoy the pictures and your soup without the cold!

    What could I sub for the flour? I’m allergic to almond flour, but could I maybe use coconut flour?

      I’m sorry, I don’t know much about the different kinds of flours. When we make something gluten free we use potato starch or almond flour. Coconut flour sounds delish!! Let us know if it works!

    Oh, this would be yummy! My one son has the same thought on veggies as your son…he only likes them highly processed like processed by cows so they are now beef! I have to try this though, I love creamy veggie soups
