Notes

Chef Jenn's Tips

  • Depending on the size of your casserole dish and the size of the cauliflower you used, you may not have to use all of it. Save some for another meal - just remember there is raw egg in it so it should be heated through to cook the egg.
  • The beef mixture should be creamy but not soupy. Be sure to drain off excess fat before adding the cream cheese.
  • Don't skip the garnishes - they add so much to this dish and really amp up the flavors!
  • Don't care for mashed cauliflower? Skip this layer! Serve the dish with your favorite vegetable sides instead, like Green Beans Almondine with Bacon or bacon-wrapped asparagus.
