Personal Anecdote
I remember the first time I made a christmas breakfast casserole. It was one of those years where we had a full house—kids, cousins, too many people and not enough coffee. I was a little nervous, honestly, because I’d never made a casserole for breakfast before. But everyone dug in while the tree lights blinked and, you know, it just felt right. It’s become our breakfast tradition ever since.
Why This Recipe is Special
This one’s special because it’s such a no-fuss way to feed a crowd. You do all the work the night before, so on Christmas morning you’re just sipping tea and waiting for the oven timer. And, well, it’s filling. The bread soaks up all the flavor, the cheese gets all melty, and the sausage—wow.

Step-by-step method
Step 1
First, in a skillet over medium heat, brown the sausage until it’s cooked through and golden. The smell will start to fill your kitchen, and you might even get a little impatient. Sometimes the sausage sticks just a bit, but that’s okay—it adds flavor!
Step 2
Next, scatter the bread cubes in a 9 x 13-inch casserole dish. Sprinkle the grated cheddar cheese and cooked sausage right on top. It never looks perfect in the pan, but trust me, it all comes together. In a bowl, whisk 2 ½ cups of milk, eggs, and dry mustard, then pour this over the bread, cheese, and sausage. Cover and pop it in the fridge overnight. Sometimes I forget and leave it out for a few minutes, but it still works.
Step 3
When morning comes, preheat your oven to 300°F. Whisk together the cream of mushroom soup and remaining ½ cup milk, then pour that over the casserole. Bake uncovered for one hour, until golden and bubbling. If you want to try a fruity twist, my Blueberry French Toast Casserole Breakfast Recipes is a favorite here, too.
Tips and tricks to make this recipe shine
Try using day-old bread so it soaks up all the flavors. Don’t worry if the top browns faster than you expect—just tent with foil. You can swap cheddar for your favorite cheese. And if you forget to prep the night before, you can let it soak for just a couple hours, but overnight is best for that classic christmas breakfast casserole texture.
What to serve with this recipe
Honestly, this christmas breakfast casserole is hearty by itself, but sometimes I like to add simple sides. Serve with a fruit salad or a bowl of fresh berries for a pop of color and sweetness. Toast or English muffins make a great addition for anyone who loves a little crunch. If you’re in the mood for something even more comforting, check out my Biscuit Gravy Casserole Breakfast Recipes for another cozy option. Sometimes I just put out a pot of coffee and let everyone dig in—no fancy setup needed, because it’s all about togetherness.
How to store and reheat
Leftovers of this christmas breakfast casserole keep well in the fridge for up to three days. Just cover the dish with foil or transfer to an airtight container. When you’re ready to reheat, a quick stint in a 350°F oven for 15 minutes will do the trick. The microwave works, too, but sometimes the bread gets a bit chewy—still tasty though! If you freeze portions, thaw overnight in the fridge before reheating for the best texture. Sometimes I forget to label the container and get a surprise breakfast later!
