Christmas Morning Breakfast Casserole is my secret weapon for the kind of holiday morning where you want the house to smell amazing, but you do not want to be standing at the stove flipping batches of something while everyone is unwrapping gifts. I started making this years ago after one too many Christmas mornings where breakfast got pushed late, people got hangry, and I felt like I missed half the fun. This one goes in the oven and just handles itself while you make coffee and enjoy the cozy chaos. It is warm, filling, and honestly a little nostalgic in the best way. If you need a breakfast that feels special without being stressful, you are in the right place.
Why We Love Christmas Breakfast Casserole
I love recipes that make people relax, and this is one of them. A Christmas Morning Breakfast Casserole has that perfect mix of comfort and celebration. You get the savory goodness of sausage, the soft baked eggs, and those golden bread cubes that soak up all the flavor. It tastes like something you worked hard on, even if you did most of it the night before.
Also, it is super flexible. Got picky eaters? Keep it simple with sausage and cheddar. Want it a little fresher? Toss in bell peppers or green onions. Want a little heat because your uncle puts hot sauce on everything? Add diced jalapenos. It is forgiving, which is exactly what I want on a holiday morning.
And because I always get asked, yes, you can absolutely prep it ahead. That is kind of the whole point. If you like other make ahead breakfasts too, you should peek at this easy French toast casserole overnight baked breakfast because it is another holiday hero when you want something sweet on the table.
Here is the vibe this casserole brings to your morning, in plain terms:
Less cooking during the fun, more time with your people. And more importantly, everyone eats at the same time, which feels like a miracle on Christmas.

How to Make Christmas Casserole
I am going to walk you through my go to version. This Christmas Morning Breakfast Casserole is savory and classic, and it feeds a bunch without a bunch of drama. I usually build it the night before, cover it, and bake it in the morning. The flavors get even better after a rest in the fridge.
What you will need
- Bread: 6 to 7 cups cubed, like French bread, sourdough, or even sandwich bread
- Breakfast sausage: 1 pound, cooked and crumbled
- Eggs: 8 large
- Milk: 2 cups, whole milk is best but any works
- Cheese: 2 cups shredded cheddar or a blend
- Salt and pepper
- Optional: garlic powder, onion powder, paprika, diced peppers, green onions
- Butter or cooking spray for the dish
Simple step by step directions
1) Grease a 9 by 13 baking dish. Add your bread cubes in an even layer.
2) Brown the sausage in a skillet, then drain any extra grease. Sprinkle it over the bread.
3) Add about 1 and a half cups of the cheese right on top. Save the rest for later.
4) In a big bowl, whisk the eggs, milk, salt, pepper, and any extra seasonings you like. Pour that over everything slowly so it soaks in.
5) Press down gently with a spoon so the bread gets coated. Cover and refrigerate at least 4 hours, or overnight.
6) In the morning, take it out while the oven preheats to 350 F. Bake uncovered for 40 to 50 minutes. When it is almost done, sprinkle the remaining cheese on top and bake 5 to 10 more minutes.
7) Let it rest 10 minutes before slicing. That little wait helps it set so the pieces come out neatly.
My best tips so it turns out right
Use slightly stale bread if you can. Fresh bread works, but day old cubes soak up the egg mixture better and do not get mushy. If your bread is super fresh, cube it and leave it out on the counter for 30 minutes while you cook the sausage.
Another tip is seasoning the eggs. I know it sounds obvious, but it is the difference between okay and wow. Even just salt, pepper, and a pinch of garlic powder makes it taste like something you would order at a brunch spot.
And if you are a fan of hashbrowns in breakfast bakes, this easy sausage hashbrown breakfast casserole is worth saving for another weekend. Different texture, same cozy payoff.
“I made this Christmas morning and it was the first year I did not feel rushed. Everyone grabbed a slice, went back for seconds, and I actually got to sit down with my coffee. This recipe is a keeper.”
Feeding a Crowd? Try These!
If you are hosting family, neighbors, or the random friend who stops by for cinnamon rolls, a Christmas Morning Breakfast Casserole is basically built for it. You can double it if you have two pans, or you can stretch it with a couple smart sides.

Here are a few easy ways I make it work for a crowd:
Make a topping bar: Put out salsa, hot sauce, sour cream, and sliced avocado. People love customizing their plate, and it makes the meal feel more festive.
Add fruit: A big bowl of oranges, grapes, and berries keeps things fresh and balances the rich casserole.
Serve something handheld too: If you have teens or kids roaming around, something grab and go helps. This easy breakfast quesadilla quick morning is great for that, especially if some people wake up earlier than others.
Do a fun holiday side: If you want a cute centerpiece snack while the casserole bakes, this basil pesto cheesy puff pastry Christmas tree recipe is one of those recipes that makes everyone say, wait you made that?
One more practical thing: if you are feeding a crowd, bake it until the center is fully set. If your pan is very full or your fridge is cold, it may need an extra 10 minutes. I start checking at 40 minutes, but I do not panic if it needs a little longer.

I am the kind of cook who loves casseroles because they are comforting and reliable. If you are in a casserole mood beyond breakfast, try this baked beans ground beef casserole on a chilly evening. Totally different flavors, but it has the same easy, satisfying vibe and it feeds a lot of people without much fuss.
Also, if you want to turn your Christmas Morning Breakfast Casserole into a whole brunch situation, you can pair it with a sweet option like baked French toast, then add fruit and coffee. That mix of sweet and savory always feels like a holiday win.
More Breakfast
Sometimes the best Christmas morning is a little buffet situation. If that sounds like you, think about doing two make ahead dishes, one savory and one sweet, so everyone is happy. I usually do my Christmas Morning Breakfast Casserole as the main, then add either fruit or something baked that feels special.
And do not forget the small stuff that makes it feel like a holiday morning: warm mugs, extra napkins, and letting people snack while the oven does the work. If you have kids, they love being the official cheese sprinkler on top during the last few minutes of baking. It is messy, but it is the good kind of messy.
Common Questions
Can I make this the night before?
Yes, and it is better that way. Cover it tightly and refrigerate overnight, then bake in the morning.
How do I know when it is done?
The center should look set, not jiggly, and a knife inserted in the middle should come out mostly clean. If the top is getting too dark, loosely cover with foil.
Can I use bacon or ham instead of sausage?
Absolutely. Cook bacon first, or use diced ham as is. Just make sure any meat you add is not super wet.
What if I want it without bread?
You can swap bread for hashbrowns or cubed roasted potatoes. The bake time may shift a bit, so keep an eye on the center.
How do I store leftovers?
Keep slices in an airtight container in the fridge for up to 4 days. Reheat in the microwave or in the oven until warmed through.
