Overnight Cheesy Sausage Breakfast Casserole Recipe Makes Christmas Morning Less Hectic

Christmas week is especially hectic, and let’s face it, moms and dads are the real Christmas magic (and it’s exhausting!). Here’s a way to make your life a little easier. Throw this breakfast casserole together the day before Christmas and then pop it in the oven on Christmas morning. While it bakes the kids can open their gifts. By the time they’re done putting together/playing with/reading their favorite gift, this cheesy sausage breakfast casserole will be ready to eat!

This easy baked breakfast casserole recipe is perfect during a hectic week, but I especially appreciate these types of recipes if I’m hosting on Christmas or traveling. I think you will, too. They’re also great for a potluck Christmas brunch, which we’ve been to with neighbors a couple of times. If you have any leftovers (which is pretty doubtful!), you can store theme in the fridge for up to five days. When you’re ready, just reheat in the oven or microwave or oven until warmed all the way through.
