The Perfect Christmas Breakfast!

Christmas morning is filled with activity and fun, so who wants to step away from the magic to make breakfast? That is why I LOVE whipping up a tasty breakfast casserole the night before. The next morning I simply pop it in the oven and return to the fun.

This Christmas breakfast casserole is brimming with flavor and hits all of your basic breakfast food groups ;). It has the salty sausage, filling bread, and creamy egg. It’s basically a meal in a pan, and who doesn’t love that?

Now this does not need to be made the night before, but does require some chill time. It is perfect for family breakfast or brunch with friends so be sure to give it a try!

Change it up!

When it comes to the Christmas season, I really like when I come across something that is simple and I think this Christmas breakfast casserole is perfect in its use of simple ingredients that I always have on hand. However, you can easily add different ingredients to make it your own. Some ideas include:

  • Add crumbled bacon to the top
  • Use cubed ham instead of sausage
  • Add diced red and green bell peppers
  • broccoli florets, artichokes, sauteed mushrooms
  • Use your favorite cheese
  • Use different bread like challah, French bread, Brioche, Texas toast

So many ways to change it up, but keep this recipe so easy and delicious!

Make Ahead + Storing Tips

Overnight: This casserole is especially perfect to make the night before that way all you have to do on Christmas morning is put it in the oven. Just like when you make french toast, you want to allow enough time for the egg mixture to soak into the bread. You’ll need at least 2 hours to let the bread soak, but overnight is best. 

Some may worry that soaking too long will result in the casserole being soggy. One trick is to use stale bread. To help your bread dry out a little faster you can pop them in the oven for 8-10 minutes at 350 degrees F. 

One other baking tip is to allow the casserole to sit out for about 30 minutes before baking. This will allow the casserole to bake more evenly. 

Storage: If you want to prepare your Christmas breakfast casserole further in advance than overnight you can cover the dish with plastic wrap and again with foil. Label and freeze for 1-2 months. Thaw in the fridge before removing the wrappings and baking. 

To store leftover casserole, divide it into individual sized storage containers. Keep in the fridge for 3-4 days or in the freezer for 2-3 months. Thaw, if applicable, and reheat in the microwave or oven.
