Low Carb Cauliflower and Broccoli Cheese Soup

4.5 from 2 reviews

Thick and hearty! Everything a warm and comforting soup should be!




  1. Heat a large sauté pan over medium heat. Add the butter, onion, garlic, sea salt and black pepper to the pan. Saute until the onions are nice and caramelized. About 20 minutes.
  2. Heat slow cooker on high setting.  Add caramelized onions, cauliflower, broccoli, leek, chicken stock, heavy cream and a little sea salt and black pepper.
  3. Mix all ingredients together. Cover and cook on high for 5-6 hours.
  4. After 5-6 hours the vegetables will be nice and tender. Using a potato masher, mash up the vegetables. Alternately, you can use an immersion blender for this. (I found that the vegetables were soft enough that I just gave them a quick mash and the soup was the exact texture I was looking for.)
  5. Mix in cheddar and Parmesan cheeses, more salt and pepper (if desired) and allow to cook 1 additional hour.
