  • 4 cups cauliflower florets chopped into bite-sized pieces
  • 6 oz. cream cheese cut into chunks
  • ¼ cup heavy cream
  • 3 Tbsp unsalted butter softened
  • ¼ tsp garlic powder
  • ½ tsp dried dill
  • Sea salt and black pepper to taste
  • cup Italian cheese blend shredded
  • 4 strips bacon cooked and crumbled
  • 1 Tbsp fresh chives chopped


  • Start by taking out the butter and the cream cheese to sit on the counter to soften.
  • Place top oven rack in the center position and preheat oven to 400°F.
  • You will need to pre-steam or blanch your cauliflower.
  • To Steam Cauliflower Stove Top: Place the cauliflower in a steamer basket on top of a pot with boiling water and steam until fork-tender, around 6-7 minutes.
  • To Steam Cauliflower in Microwave: Place cauliflower and 2 tablespoons of water into a microwave safe bowl. Cover the bowl with a microwave safe plate. Then, microwave on high for 3-4 minutes.
  • To Blanch Cauliflower: Boil a pot of salted water with 1 cup of heavy cream. Then, add the cauliflower florets to the pot of boiling water. Boil for 9 minutes and strain. Cauliflower should be able to pierce with a fork easily.
  • Then, in a large bowl add cold water with ice cubes to blanch the cauliflower. This stops the cooking process.
  • Once the cauliflower is cold to the touch (5 to 10 minutes), you can strain it again and set aside. Drain well and pat dry.
  • Transfer steamed cauliflower to a large bowl and add cream cheese, heavycream, butter, garlic powder, and any added spice. Then, season with salt and black pepper, to taste, and toss to combine.
  • Transfer to oven-safe casserole dish and top with shredded cheese and crumbled bacon.
  • Place in pre-heated oven and roast until cheese is melted and nicely browned on top, around 8-10 minutes.
  • Remove from oven and serve immediately topped with fresh chives. Enjoy!
