  • 2 medium heads cauliflower , chopped into small florets (about 3-4 cups)
  • 1/3 cup chopped celery
  • 2 teaspoons olive oil
  • 4 ounces cream cheese , softened at room temperature
  • 1/3 cup sour cream
  • 1/2 teaspoon fine sea salt , or to taste
  • 1/4 teaspoon freshly cracked black pepper , or to taste
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1 cup Monterey Jack cheese , shredded and divided
  • 1/3 cup cooked and crumbled bacon , (leave out for vegetarian)
  • 1/2 cup sharp cheddar cheese , shredded
  • 1/2 cup crumbled Parmesan cheese crisps , optional for topping (I used Whisps) or can also use pork rinds
  • 2 tablespoons chopped fresh green onions , for topping
  • 1 tablespoon chopped fresh parshley , for topping


  1. Preheat oven to 400F degrees F. Lightly grease a 9x13 casserole pan and set aside.
  2. Spread cauliflower and chopped celery in a single layer onto a large baking sheet. Drizzle with olive oil and roast for 20-25 minutes, or until tender.
  3. Meanwhile, in a large mixing bowl, combine the cream cheese and sour cream. Beat until smooth. Season with salt, pepper and add garlic powder and onion powder. Fold in half of the Monterey Jack cheese and half of the bacon bits, if using.
  4. Once the cauliflower is tender, stir into the cheese bowl until combined.
  5. Transfer the cauliflower to prepared casserole pan and spread into an even layer.

  6. Sprinkle with remaining Monterey Jack cheese, cheddar cheese and crumbled bacon. Top with crumbled cheese crisps (or crumbled pork rinds), if using.
  7. Bake in the oven for another 10-15 minutes, or until cheese has melted.
  8. Top with green onions, parsley and serve hot.
