  • 6 slices of bacon
  • 1 large head cauliflower
  • salt
  • 1/2 cup sour cream
  • 4 oz cream cheese, softened
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup chopped green onions, extra for garnish
  • 1 tsp garlic powder or 1 or 2 cloves of garlic pressed
  • pepper
  • 1 cup shredded cheddar cheese


1. If using precooked bacon, allow to cool then chop. If using fresh bacon, fry bacon in a large skillet over medium heat. Transfer to a paper towel-lined dish, allow to cool, and then chop. 


2.  Core cauliflower and chop the florets into small pieces. 


3. In a large pot of boiling salted water, boil cauliflower until soft. 15 to 18 minutes for chunkier texture or 20 to 22 minutes for super-smooth texture. 


4. Meanwhile, in a large mixing bowl, combine the sour cream, cream cheese, Parmesan cheese, green onions, garlic powder, and two-thirds of the bacon. 


5. Preheat oven to 350°F.


6. Drain cauliflower well and pour cauliflower over cream cheese mixture into the bowl. Mash with a potato masher or whisk until the constistency of your liking. Season to taste with salt and pepper. 


7. Spread the cauliflower mixture evenly in an 8-inch square casserole dish. Top with cheddar cheese and remaining bacon. 


8. Bake for 15 to 20 minutes, until cheese is melted. Garnish with chopped green onions before serving.
