CrockPot breakfast casserole goes from the slow cooker to the table in a matter of hours! Set the Crock Pot at night and get some rest, or whip it up in the morning! Either way, breakfast is ready with all the right flavors to get everyone’s day started off right!
A combination of shredded hash browns, sausage or ham and lots of cheese is covered with eggs and “bakes” to perfection in the slow cooker. Making a CrockPot breakfast casserole recipe has never been easier!
How To Make a Breakfast Casserole (Crock Pot Version)
- HASH BROWNS: Shredded hash browns work best in this recipe. If you prefer more ‘potato’ in your casserole, you can certainly use diced hash brown potatoes or homestyle potatoes.
- MEAT: I most often use sausage or ham. Bacon (or really any breakfast meat) will work perfectly in this recipe!
- CHEESE & EGGS: I love the flavor sharp cheddar adds but any cheese works. Use whole eggs or even low fat egg substitute.
- TOPPINGS: Feel free to add salsa or Tabasco and once you’re ready to serve, a nice dollop of sour cream and some chopped green onions!
To make Slow Cooker Breakfast Casserole:
- PREP: prep the veggies and dice the meat.
- WHISK: whisk the eggs, milk, dry mustard, and salt and pepper.
- LAYER: layer the hash browns, meat, onions, cheese, and peppers. Repeat, ending with cheese.
- COOK: cook on HIGH for 2 1/2 to 3 hours, or LOW for 7-8 hours.

How Long to Cook a Breakfast Casserole
This slow cooker breakfast casserole recipe will take about 7-8 hours on LOW and 2 1/2 – 3 hours on HIGH in a 6QT slow cooker. If you’re working with a smaller slow cooker or doubling the recipe, the cooking time may need to be adjusted slightly to compensate.
Can You Freeze CrockPot Breakfast Casserole?
Like all casseroles, the best way to freeze them is to make sure they are fully cooled before they’re put in the freezer.
Once it is fully baked, chill overnight and then the next day, remove and either slice into portions and freeze individually or freeze in sections in a plastic bag. Just reheat in the microwave! Easy to make and easy to clean up!

Could this be made with grated potato instead of hash browns to make it more slimming world friendly please?
Hi Joanne, we have only made this recipe as listed but I think shredded potatoes should work in this recipe. Let us know how it turns out!
I am not a fan of the red and green peppers or any. What might you use to replace them with, broccoli?
We have only made this recipe as listed, but that sounds like a delicious substitution Barbara.
I make it every Christmas. Waking up to that delicious smell is wonderful. My grandchildren love it. I use Bob Evans original sausage.
Just wonderful enjoy a wonderful breakfast, no trouble. Finger licking good
Hey there,
Last time I made a similar casserole to this, the water from the frozen hash browns made the casserole extremely watery. Did you notice this with your casserole?
Hi Alexis, we did not have that problem with this recipe. Hope you love it!
Thanks
It turned out amazing! Loved it and had great flavor! The only thing I did different was I used potatoes o brien and even though those potatoes already had all the yummy veggies, I still followed the recipe exactly. :)
So happy to hear that Lisa!
Made it last night, was really looking forward to waking up this am to a really good breakfast. Very disappointed. It looked great but was lacking in taste. My husband and I agree that it needs something….I will keep looking for something similar but this was definitely a miss !!
Oh no Connie, how disappointing. I’m sorry you didn’t enjoy this dish as much as we do. Perhaps a spicy seasoned sausage would help.
What a superb casserole! Looks so cosy and full of amazing flavors!
Thanks Michel! It has so many delicious flavors!
Creamy, delicious and surely a hit at my breakfast table from now.
So happy to hear that Veena! Enjoy.
I never had breakfast casserole before but this sure looks comforting, delicious and perfect for hearty breakfast ♥
It is so yummy Natalie! Enjoy.
Wow!! This is some seriously good breakfast food right here and I love it!! I also love the touch of mustard in the recipe and that it is big enough to feed a crowd, can’t wait to try it. Cheers!
Thanks Adrianne! Can’t wait for you to enjoy it!
This is seriously my fave breakfast now!
So glad you love is as much as we do Jocelyn!
has anyone made this with the ingredients cut in half?
If you double the recipe will it still fit in a 6qt crock pot?
I would not suggest doubling this recipe as it would likely not cook through.
If you cut this recipe in half, should you also cut the cooking time in half?
I haven’t tried halving this recipe so I can’t say for sure. I do think it would need about 3/4 of the cooking time. You’ll want to make sure the eggs are cooked through. Let us know how it goes.
Am planning on making the Slow-Cooker Breakfast Casserole for a brunch tomorrow. Just wondering about the hash browns. Should they be thawed before putting them in the slow cooker.
Thank you.
They can be frozen when you add them. Let me know how it turns out!
Can you use tater tots instead
I haven’t tried it but I do have a tater tot casserole recipe made in the slow cooker so I think it would work just fine!
Contemplating somewhat heavily on trying this little casserole recipe out for Christmas morning; I have one question though: Where do you put the diced and cooked bacon, on top of the casserole when done, or the interior of the casserole the bacon once it’s well-cooked, or the bottom of the thing? The recipe doesn’t specify where you put it at all (at least for me). Other than that, it looks so dang good! Merry Christmas, Holly!
It is added in step 2.
Would this be ok to mix the night before and put in fridge?
Yes, that will work just fine!
If I bake this in the oven what temperature should i use and how long to bake it. I want to make it for a brunch
I have a delicious breakfast casserole in the oven here:
Breakfast Casserole with Sausage
and this one is delicious as well Overnight Breakfast Casserole
Has anyone made this in the oven? If so, what temperature and for how long? Does it fit in a 9×13 dish?
Hi Olga, we haven’t made this one in the oven but for delicious oven-baked breakfast casseroles we always turn to Breakfast Casserole with Sausage or an Overnight Breakfast Casserole
This looks delicious can’t wait to try it. Out of curiosity, have you ever tried adding Spinach to this recipe? If so, how did it go?
That sounds like a great addition to the recipe and would give it a nice addition of color!
Hello. Im curious what the white substance is in the pic. Sour cream?
It’s a little bit of the egg white that wasn’t stirred in.
Can you half this recipe? It’s just my girlfriend and myself. I know we won’t be able to finish it all and don’t want to waste it. If it’s in half, would the time be different?
Yes, you can half this recipe (and I have many times). I cook it in an 8×8 dish for about 40 minutes (ensure a knife comes out clean). If you do end up with leftovers, it reheats beautifully.
Hello, I was curious if you know anyone that has tried egg substitute like EggBeaters? Thanks.
I am disappointed! Only thing different is I added mushrooms and this turned out awfully dry and bland! I’m glad I woke up early and checked on it because it would have been completely inedible by 6am after being on low for 8hrs! It is dry and crispy! Good thing my hubby will still eat it, he doesn’t like to waste food!
Oh no Kristy, I’m so sorry this didn’t work out for you. How disappointing!! My slow cooker cooks this recipe perfectly with very slightly crispy edges. What size of slow cooker did you use?
How many will this feed?
This recipe should feed 8 people.
Will the eggs turn rubbery if you cook it for 8 hours on low then let it sit on warm until everyone is up and ready to eat breakfast?
I think it should be just fine on warm. The eggs are mixed with milk which softens them slightly.
Approximately how much salt do you end up adding?
I usually add just over 1/2 teaspoon.
I tried the recipe on high for 4 hours and it was delicious. Thank you for the recipe and idea. My family loved it and my husband woke up this morning on father’s day to this delicious breakfast. And breakfast is his favorite meal so he was in heaven. He said this is my breakfast lunch and dinner!!!
Thank you again.
I’m so glad your family loved this!
How long can this be kept on warm on a buffet after it is cooked? Need to cook it overnight but guests not arriving until 10-11 am, don’t want to have to stay up too late!
Could you double the recipe ?
We are looking to feed more than 8 people for a brunch
Thanks!
I would not suggest doubling this recipe as it would likely not cook through.
This sounds great, I plan to make this for friends as a thank you for helping my fiance and I stuff our wedding invitations this coming Sat morning.
Do you know if shredded russet potatoes would work, rather than frozen?
Thank you!
I haven’t tried it with russet potatoes so I can’t say for sure. I *think* it would work though.
I can’t tell from the pictures…. does it matter what type of frozen hashbrowns? Shredded, o’brien, etc.
I have made it with both shredded and diced hash browns. Both work perfectly.
Can you cook on high for 2 hours in crockpot
I haven’t tried it that way. If you do, I’d love to hear how it works for you!
My mother-in-law came in town and this was a big hit. Even the kids loved it.
So glad everyone loved it!
I am cooking for one – How many days will this last? If I make it on Sunday night can I eat it for breakfast throughout the week?
I haven’t kept it longer than 3 days. If you would like to keep it longer you may try freezing it. Please let us know how it works out for you.
What is the best size of crockpot to use and how many does it feed?
My brother made it for a brunch for a bunch of his friends.
Thanks!
This serves 8. Any size of slow cooker will work. I use a 6qt slow cooker.
Could u somehow convert this recipe to an instant pot version?
Hi Michelle, we have never tried this in the instant pot. Maybe another reader has and can offer some guidance!
Do you think this is something that could be made on a Thursday night and keep it in the fridge until Saturday morning? If I’d make the dish ahead of time then add the eggs and milk before I heat it up
I think that would work perfectly.
this looks so good! We do Thanksgiving breakfast at our house. This would be a great thing to make and free up some space on the stove and in the oven!
