Low-Carb Cauliflower Cream Soup

Blue cheese toasts add a nice touch of flavor contrast to this soup, but can easily be omitted if you’re watching your carb count.

Serves: 6


  • 1 large head cauliflower
  • 1⁄4 cup butter
  • 1 medium onion, chopped
  • 2 cups chicken stock
  • 2 cups milk
  • 1⁄2 tsp. salt
  • 1⁄2 tsp. freshly ground white pepper
  • 1⁄4 cup crème fraîche or sour cream
  • 6 oz. blue cheese, softened
  • 1 French baguette, sliced and toasted


  • Cut the cauliflower into flowerets. In a large pot of boiling salted water, blanch the cauliflower for 3 minutes. Drain through a colander.
  • Melt the butter in a large saucepan over medium heat. Add the onion and cook until tender. Add the stock, bring to a boil; and reduce to a simmer for about 20 minutes. Stir in the milk and add the cauliflower. Season with salt and pepper, and simmer for 10 minutes. Using a slotted spoon, remove and reserve 1⁄3 of the cauliflower.
  • In a blender or food processor, blend the soup until smooth. Strain the soup through a fine-mesh sieve into a clean saucepan. Stir in the crème fraîche (or sour cream) and add the reserved cauliflower. Reheat very gently.
  • Spread the softened blue cheese onto the toasted baguette, and serve alongside soup.
