Once its done add your cream cheese and cheddar cheese. Using an immersion blender puree the soup until it is smooth and creamy. Stir in most of the bacon.

Notes
If you would like to have some chunks in your Bacon Cheddar Cauliflower Soup, when you are done cooking it in the crockpot, remove a scoop of the cooked cauliflower and set it aside. Then just add it back into your soup after you have used the immersion blender to mix it all up.
