Keto Cauliflower Casserole

When you are craving comfort food, it doesn't get any better than this Keto Loaded Cauliflower. It makes a great side dish, though I often serve it as a main course. If you are looking to reduce the calories, simply omitting the bacon will save you 100 calories per serving. (Though, really, life is pretty short to skip the bacon, right?)

  • 2 heads cauliflower cut into florets
  • 8 ounces cream cheese cubed and at room temperature
  • ½ cup unsalted butter sliced and at room temperature
  • 1 cup sour cream
  • 1 ½ teaspoons sea salt
  • ½ teaspoon fresh ground black pepper
  • ¼ teaspoon cayenne pepper
  • 2 cups shredded cheddar cheese divided
  • 8 ounces bacon cooked and crumbled, divided
  • ¼ cup chopped fresh chives


  • Preheat the oven to 400° F. Spray a 9" x 9" pan with cooking spray.
  • Bring a large pot of salted water to a boil. Add cauliflower and cook for 5 minutes.
  • Drain and place the cauliflower on paper towels to absorb excess moisture.
  • Transfer to a food processor and add cream cheese, butter, sour cream, salt, pepper, and cayenne pepper. If you would like the consistency to be thinner, add in heavy cream 1 tablespoon at a time.
  • Process for 3 to 5 minutes, until very smooth.
  • Add 1 cup of cheddar cheese, half of the bacon, and the chives. Pulse until just combined.
  • Transfer to a baking dish and top with the remaining cheese and bacon.
  • Bake for 20 minutes. Garnish with additional chives if desired.
