  • 1/2 tsp sea salt
  • 1 large head cauliflower cut into bite-size pieces
  • 1 cup heavy cream
  • 2 oz cream cheese
  • 1 cup blue cheese divided (reserve 1/2 cup for topping)
  • 2 cups shredded sharp cheddar divided (reserve 1/2 cup for topping)
  • 1/4 tsp freshly ground black pepper
  • 1/4 tsp garlic powder
  • 1 lb cooked bacon chopped


  • Preheat oven to 375 degrees F.
  • Grease a medium casserole dish with butter or oil. Bring a large pot of water to boil, seasoning the water with salt.
  • Boil the cauliflower until slightly tender, about 5-8 minutes. Drain well and return to the warm pan to steam off more water.
  • Mix bacon into the cauliflower and transfer the mixture to the baking dish, distributing evenly.
  • To make the sauce: On medium-low heat, simmer the heavy cream. Whisk in cream cheese until creamy. Add salt, pepper, garlic powder, 1/2 cup blue cheese, and 1 1/2 cup cheddar cheese. Mix until creamy.
  • Pour the sauce evenly over the cauliflower. Top the dish with the remaining blue cheese and cheddar cheese.
  • Bake for 10-12 minutes, then broil for 3-4 minutes to crisp and brown the top.
  • Allow to cool for 5-10 minutes and serve.
