There isn’t much that’s easier than getting up on Christmas morning, making coffee, and popping your already prepared breakfast casserole into the oven before tackling the gifts under the tree. Then you can smell your delicious breakfast as it bakes. What a nice feeling. Leave some space in your refrigerator on Christmas Eve to allow this to sit in there overnight.

I thought that this year, I’d just throw together some of our favourite foods for our ham and swiss casserole for breakfast. Add my husband’s hollandaise, some sausage gravy, or some mushroom cream sauce to it, and YOWZA you have an amazing meal.
