An amazingly rich and tasty cauliflower casserole is keto and low carb.



  • 1/4 teaspoon black pepper
  • 1 teaspoon coarse kosher salt (not fine salt)
  • Olive oil spray
  • Pinch cayenne pepper
  • 1 teaspoon Dijon mustard
  • 1 cup shredded sharp cheddar, divided
  • 2 tablespoons whole milk (or cream)
  • 1 large head cauliflower, cut into small florets (1.5 lb. florets)
  • 1/2 cup sour cream (I used low-fat, feel free to use full-fat)
  • 1 teaspoon minced garlic


  • 2 tablespoons bacon bits
  • 2 tablespoons thinly sliced scallions, green parts


  1. Preheat oven to 425 degrees F. Line a rimmed baking sheet with parchment paper.
  2. Arrange the cauliflower florets on the baking sheet. Liberally spray with olive oil and season with kosher salt and black pepper. Roast the cauliflower until tender-crisp, about 12 minutes.
  3. Meanwhile, in a large bowl, mix the sour cream, milk, Dijon, garlic, cayenne and 1/2 cup cheddar.
  4. When cauliflower is done, add it to the sour cream sauce and mix to combine.
  5. Transfer the mixture to a greased 1.5-quart baking dish. Top with the remaining shredded cheddar.
  6. Return to the oven and bake just until cheese is melted, about 10 minutes.
  7. Sprinkle the cauliflower casserole with the bacon bits and the scallions and serve.
