Recipes that are made ahead of time are some of the best to have in your back pocket. Just pull them out when you’re having company or heck just used them to treat yourself. I hate to be rushed and anything that can be done the day before makes life easier. I have been using this recipe for years. It is our traditional Christmas morning special. Many breakfast casseroles call for as many as a dozen eggs and this one only uses four eggs. That’s really reducing the amount of cholesterol which is a good thing.
