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.
