This Overnight Sausage and Egg Breakfast Casserole is a classic breakfast in our house! I’ve been having it on holiday mornings since I was a kid and have carried the tradition into adulthood. It’s a wonderfully easy breakfast to share as a family on busy holiday mornings!
An Easy Overnight Breakfast Casserole
Every Christmas for as long as I can remember, we’ve had this breakfast casserole for breakfast. We also tend to have it for Thanksgiving, Easter and any day it seems appropriate. Shoot, the hubs would happily have it all year long.
Of course since Christmas is also my birthday, I have added my own little tradition to the mix. Not only do we have this breakfast casserole for the savory lovers, but we also have this Cake Batter French Toast Casserole – and yes, I eat it with the frosting warmed up and poured all over it. 🙂 Oh my gosh, I’m drooling just thinking about having it again a week from today. Now if you head over and check out that casserole – and I hope you do – you’ll have to excuse the bad old photos. If you want to see where I started as far as photography, check that out. 🙂 Also, there’s a pretty long and hilarious story that we still talk about to this day. Good times.
But back to the savory casserole! This is the one that makes you feel a little healthier and like it’s ok to indulge in the birthday one. Even if you aren’t celebrating my birthday on Christmas, there’s Jesus’ birthday too. 😉
How to Make this Breakfast Casserole Recipe
Anywho, this casserole is maybe the easiest thing ever to put together. There are so many versions out there, but this is the one I use and love. It’s wonderful to wake up in the morning and have it ready to go straight into the oven. On Christmas, we often pop it the oven, then open some presents while it bakes.
To get started making it, there’s some bread. I don’t use fresh bread from the bakery in this one, like I would a french toast casserole, because I don’t want anything too firm or crunchy. I want the eggs and sausage to shine in here. I tend to use a regular loaf of bread, often of the sourdough variety because I love it. But really any should work just fine.
Sausage and cheese are sprinkled over the bread and let’s be honest, you can’t go wrong with either of those. A full pound of sausage and two cups of cheese should be plenty, but if you feel the need for more you go for it!
Then we’ve got eggs, milk, and some dry mustard, salt and pepper for flavor. The whole casserole is covered and stored in the fridge overnight. Baking it the next morning couldn’t be easier!
You may need to bake it for a little more or less time depending on your oven and how soft or “runny” you prefer the casserole to be. I don’t really like it to be runny, but I also don’t want it to dry out. To check it, use a fork or knife to stick in the middle and see how soft it still is. When it’s done, you’ll definitely be rewarded!

Description
Made with ground sausage, eggs, bread, and lots of cheese, this Overnight Sausage and Egg Breakfast Casserole is the perfect breakfast for holiday mornings or weekend brunch. Easy to prepare & loved by the whole family!
Ingredients
- 6 slices bread, cubed*
- 1 lb sausage, browned and drained
- 2 cups shredded cheddar cheese
- 8 large eggs
- 2 cups milk
- 1 tsp dry mustard
- 1 tsp salt
- Pepper, to taste
Instructions
- Spread the bread evenly into the bottom of a greased 9×13 inch baking dish.
- Sprinkle the sausage and cheese evenly over the bread.
- In a large measuring cup, combine the eggs, milk, dry mustard, salt and pepper.
- Pour the egg mixture evenly over the ingredients in the pan.
- Cover and chill overnight.
- Prior to baking, preheat the oven to 325 degrees. Bake for 45-55 minutes, or until set. Cover it loosely for the first 30 minutes or so, then bake uncovered for the reminder. You may need to bake it for a little more or less time depending on your oven and how soft or “runny” you prefer the eggs to be. I don’t really like it to be runny, but I also don’t want it to dry out. To check it, use a fork or knife to stick in the middle and see how soft it still is.
- Remove from oven when done and serve warm.
*I like to use a little bit sturdier bread. Often I use the Pepperidge Farms Sourdough loaf.

This is so delicious. My family adds 1 tsp onion powder and 1 tsp garlic powder to the egg mixture. Would it be alright to cook in a disposable foiled pan?
I’m so glad you enjoy it! I would think the disposable pan should be fine.
Do you dry the bread first?
I don’t.
Can you make this recipe in muffin cups?
I haven’t tried it, but I’m guessing that would be fine.
Why does it rise so good when it bakes and when u take it out it falls?
It has to do with the way casseroles like this cool. It’s not that there’s a problem with what you’re doing, it just deflates as it cools.
I have an old family recipe similar to this, with the exception that the sausage goes in first. Not sure what difference it would make.
Thanks for sharing!
(And FYI, 12/25 is not the date of Christ’s birth. The date is unknown, but as the shepherds were still out in the fields at night, it has been estimated that is was around October.)
Can I make this and freeze it? With or without cooking first.
I’ve seen people say they freeze it prior to cooking, but I haven’t personally tried it either way. I would think it’d do fine freezing it after cooking it.
Can you freeze this unbaked ahead of time and bake it the morning of?
I haven’t ever tried it, but I supposed it’d be fine.
We loved it! Me being me though added a bit to it. Some worstershire sauce and some Velveeta shreds on top and dehydrated onions.
We love this recipe at holiday times. I started adding a can of chopped green chilies to my mix. If we have any left over, I cut it into single serving squares and freeze it. Great idea to use a heavier bread. I may try using a French baguette next time.
So glad you enjoy it!
Hi! Can I bake at 350 degrees? If so how how long should it bake for? I have something else I need
to bake simultaneously at 350.
Sure, I’d just check it as you go. Maybe 35-45 minutes?
This was awesome and so easy to prepare! I don’t usually leave comments, but had to this time. Thank you for sharing!
So glad you enjoyed it!
I made this for Christmas morning this year and it is delicious! Even the leftovers were tasty this morning. I’m definitely going to keep making this one. Followed the recipe exactly. It’s so quick and easy! Thank you!
My family has made this easy, yummy casserole for Christmas for years. For sone reason we all call it “Bob”!
I used to use one with tasted bread…and it wasn’t overnight….do you think u could do this recipe either overnight or that morning?
I haven’t tried doing it that morning but you can certainly give it a try. I’m sure it would be fine. It may just be better to let it sit overnight.
Would this work with frozen french toast bites instead of bread cubes?
I haven’t tried it to be able to say. You could try it. I would thaw them out first.
Do you cook the sausage prior to putting it on the bread??
Yes
