Ultra comforting Creamy Cauliflower Soup with Thyme and Sharp Cheddar is easy to love.  Simple to make and Vegan adaptable! (see recipe notes) 

I have been a seeker and I still am, but I stopped asking the books and the stars. I started listening to the teaching of my Soul. ~Rumi

The creaminess of this soup comes from the tender cooked cauliflower and sweet potato blending up silky smooth creating a luscious velvety texture.

The sweet potato may sound like a surprising ingredient!  It lends a mild sweetness that beautifully enhances cauliflower.  We are talking about white-fleshed sweet potato.  It is kind of like a cross between a russet potato and a yam, with the skin a pale yellowish-brown and the inside cream-colored.  It is milder than the orange-fleshed yam.

Sharp cheddar, thyme, and a touch of dijon bring it all to a heavenly delicious balance.

Description

Ultra comforting and dreamy Creamy Cauliflower Soup with Thyme and Sharp Cheddar is easy to love.  Simple to make and Vegan adaptable! (see recipe notes)


Ingredients

Scale
  • 2 medium shallots, 1 cup (4 oz) sliced small
  • 2 garlic cloves, roughly chopped
  • 2 tablespoons butter or olive oil
  • 1 head cauliflower, 4 cups (1 lb) cut in to small pieces
  • 1 small sweet potato (not yam), 1 cup (6 oz) cut in small chunks
  • 1 teaspoon dried thyme
  • 1 teaspoon sea salt, adjust to taste
  • 1/41/2 teaspoon black pepper, adjust to taste
  • 1 quart or 4 cups chicken broth or vegetable broth
  • 1 cup grated sharp cheddar, more to taste (the stronger and sharper the cheese the less you need to use)
  • 1 1/2 teaspoons dijon mustard

Instructions

  1. In a large pot, or dutch oven, sauté shallots and garlic in butter or olive oil for 5 minutes, over medium-low heat.
  2. Add cauliflower, sweet potato, thyme, salt, pepper, and broth.  (If making vegan, add cashews now- see recipe notes). Simmer for 25-30 minutes, until vegetables are fork-tender.
  3. If you like a few chunks in your soup, take out a cup of the veggies, set aside, and transfer the remaining soup to a blender, filling just halfway (you may need to do it in two batches) Be careful, hot soup can explode.  Start slow and vent the blender lid so steam pressure can escape.  Blend until smooth.
  4. Return to the soup pot.  Add cheese and dijon, stirring to melt cheese in, turn on low heat if needed to fully melt.  If you saved aside veggie chunks add them back in now.  Add more broth or milk to desired constancy.

Notes

Keeps in the fridge 4 days.

The stronger the cheese the less you need.  Good options: extra sharp cheddar, gruyere, comté.

Optional Bread Crumb Topping: 1 garlic clove, 2 pieces of bread- crumble together in food processor.  Toast in a skillet over medium heat along with 2 Tablespoons butter (or oil) gently toast stirring constantly for about 5 minutes.  Add a pinch of salt and pepper and 2 tablespoons minced fresh parsley.

Substitute equal parts carrot and potato for the same amount as the sweet potato.

Vegan option: add 1/2 cup of raw cashews in with the vegetables to simmer.

Vegan topping:  Vegan Cheesy Sprinkle

  1. Mine came out a little more orange rather than white due to the sweet potato. However that did not impede up on the flavor at all. I expected this to be good. However, I didn’t expect it to be as good as it actually was. I served it at a dinner party and it was a huge hit. There was absolutely none left over. This was really a remarkably good soup. I paired it with a soft bread and it was sublime. Thank you for a great recipe.

    1. Great to hear Danny, so glad everyone enjoyed! Next time if you want a less orange soup you can use a white sweet potato. 🙂

  2. This soup was exquisite! I love cauliflower and knew it was going to be delicious. The breadcrumbs were a perfect addition; I will be sure to add them whenever we make this recipe. Thank you for sharing it!

  3. Such a complexity of flavors here, they all went together so nicely. This will be my lunch for the week 🙂 thank you Tonia!!

  4. This is fabulous! I love the addition of the sweet potato. I made this in my instant pot and it turned out beautifully. Thank you!

  5. Could you tell me the purpose of the sweet potato in the cauliflower soup. I’ve never heard of this before

    1. Hi Michele, The sweet potato adds body as well as a little sweetness. It is like adding potato for texture (which you can totally use to substitute!) but sweet potatoes have more fiber and are a little lower on the glycemic index. The flavor is really nice with the thyme and dijon.🙂

  6. I made this last night. It was amazingly good and tasty. Loved the extra bread crumble on top. The Dijon added flavor that you wouldn’t expect and paired with the sharp cheese made this a keeper for sure!

  7. This cauliflower soup sounds scrumptious! I’ve never tried it with sweet potato so that will be my next soup go to. I love soup—especially in the winter! Thanks Tonia
