  • 1 3/4 lb cauliflower florets about 1 medium head
  • 4 tbsp butter melted and divided
  • 4 cups chicken broth
  • 1/4 cup heavy whipping cream
  • Fresh thyme
  • Salt and pepper to taste
  • 6 strips bacon cooked


  • Preheat oven to 425 F.
  • In a large bowl, toss cauliflower florets with 3 tbsp melted butter and salt and pepper to taste.
  • Arrange cauliflower in a single layer on a large rimmed baking sheet. Roast for 25-30 minutes until the edges are golden brown, tossing the cauliflower once during baking.
  • Transfer cauliflower to a large pot. Add chicken broth and several sprigs of fresh thyme, then bring to a simmer for 10 minutes.
  • Remove pot from heat and carefully remove thyme sprigs. Then add remaining 1 tbsp butter, heavy whipping cream, and salt and pepper to taste.
  • Using an immersion blender or regular blender, carefully blend the soup until smooth, working in batches if necessary.
  • Garnish each bowl of soup with one cooked-and-crumbled strip of bacon.


  • For a thicker soup, use only 3 3/4 cups chicken broth.
  • For a thinner soup, add more chicken broth until you reach your desired consistency.
  • If you want this soup to be higher in fat without increasing the carb count, you can add more butter.
