Cauliflower “Cream” of Mushroom Soup

9 Feb

IMAG2143Is it possible to make a thick, creamy, mushroom soup that won’t go straight to the hips? Absolutely! Here’s my slow cooker recipe for a creamy but cream-less mushroom soup – the thick texture comes from pureed cauliflower. But don’t worry, you can’t taste the cauliflower at all in this yummy soup.

You can also simmer this soup on the stove for several hours, but I like to make mine in a slow cooker so I can leave the kitchen without worrying that I’ll burn my apartment down.


  • 1 medium cauliflower, chopped
  • 1 pound mushrooms, sliced (I used 30 white button mushrooms)
  • ½ large onion, diced
  • 1 tbsp butter
  • 1 tbsp flour
  • 5 cups fat free chicken broth (or vegetable broth for a vegetarian version)
  • ¼ cup dry white wine
  • 2 garlic cloves, minced
  • 1 tsp thyme
  • salt and pepper to taste


  1. Cook cauliflower until softened. I like to stir fry it until slightly browned, then add a bit of water to the pan to let the cauliflower steam until it is soft.
  2. In a medium saucepan, make a roux by melting the butter on low heat. Add the flour and stir about 2 minutes. Then add 1 cup broth.
  3. Put cauliflower, roux, and the remaining ingredients into a 5-6 quart slow cooker.IMAG2132
  4. Cook for 5-6 hours on Medium, or 4-5 hours on High. You should be able to smell the mushrooms well before the soup has finished cooking.
  5. Using an immersion blender, puree the soup until smooth. Season with salt and pepper.

Makes 8-10 servings.

    Sounds fantastic. I need an immersion blender and I never knew it.

    You could definitely blend the soup in a regular blender as well. I’m just too lazy to transfer the soup to a different kitchen appliance 🙂
