This has been a Christmas morning tradition in my family for over 25 years. The ingredients are so simple; I think that is what makes it so delicious! It would not be Christmas without this casserole. Make this night before.

I halved this recipe to take to a work meeting today and decided to make it the day before then just heat up in the microwave at work before serving. I didn't let it sit overnight or for 8 hours and it seemed fine. It's a bit time intensive and uses a lot of dishes but my coworkers loved it--several went back for seconds. I didn't have stuffing mix but just cubed half a loaf of bread, tossed in some seasoning, and called it good. Worked well, and it is relatively easy for all the steps. I thought it was pretty good. Thanks for the recipe. Read More

I'm the sister of who posted the recipe. We've made"Christmas Casserole" since we were kids. Because it's a tiny bit time consuming to make, we only make it for Christmas, hence the original name. Over the years, I've tweaked the recipe a tiny bit for my household. I also add a small can of mushrooms, a tablespoon of minced garlic to the bacon/egg mixture. You can use bread crumbs instead of Stuffing mix for the topping, but the flavor is compromised a bit, in my opinion. I make this up to a month in advance & freeze it until Christmas morning. I start baking it when the family is up & it's typically cooked & heated throughout & ready to eat by the time gifts are done being unwrapped. Hope you enjoy our families Christmas Casserole!

This is very good as written and a little different version than many of the other breakfast overnight casserole dishes because of the addition of the stuffing mix. A nice change. I did cut it in half and it was plenty for two meals. Read More
