  • Preheat your oven to 400°F, and lightly coat a 2 quart casserole dish with oil or cooking spray.
  • Cut the cauliflower into large florets, discarding the tough stem, and steam over boiling water until very tender.
  • Drain thoroughly, and allow to cool slightly so that some of the excess moisture evaporates.
  • Place the cauliflower, Greek yogurt, egg, 3/4 cups of the cheese, salt, and pepper into a blender or food processor, and process until smooth.
  • Transfer the cauliflower to the prepared dish and sprinkle with remaining cheese, and paprika, if desired.
  • Bake for 25-30 minutes, or until heated through and browned on top.


You can also divide the cauliflower mixture between 4-6 ramekins and bake for 15-20 minutes.
The casserole can be prepared ahead of time and baked or reheated before serving.
