Heat a large pot over medium-high heat. When the pot is hot, add the bacon to the pan and cook until crispy. Once the bacon is done remove it from the pan and allow it to drain on paper towels.
Next, add the diced onion, garlic, and ghee (if using) to the pot. Cook for a few minutes until the onion becomes translucent.
Next, add the cauliflower, chicken broth, salt, thyme, bay leaf, salt and pepper to the pot. Bring the soup to a boil and then lower the heat. Let the soup simmer for 15-20 minutes or until the cauliflower are tender.
When the cauliflower florets are tender, add 2 cups of soup to a blender and blend until smooth. Pour the soup back into the pot. Remove the soup from the heat and add in the coconut milk and shredded cheese. Stir until well combined and melted.
Serve the soup with crispy bacon, green onion, and extra cheddar on top and enjoy!
