Ingredients in Slow Cooker Breakfast Casserole
- HASH BROWNS: Shredded or diced hash browns work 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 substitutes.
- 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!
How To Make Crock Pot Breakfast Casserole
- Cook sausage or bacon if using, or dice ham per the recipe below.
- If desired, soften the onion in bacon fat or a bit of oil.
- Layer hashbrowns, meat, peppers, onions, and cheese in a slow cooker.
- Whisk eggs, milk, and seasonings and pour over the hashbrown mixture.
- Cover and cook per the recipe below.
How Long to Cook a Breakfast Casserole
This slow cooker breakfast casserole recipe will take about 7-8 hours on LOW and 3-4 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 it overnight and then the next day, remove and either slice it into portions and freeze it individually or freeze it in sections in a plastic bag. Just reheat it in the microwave! Easy to make and easy to clean up!

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 ½ 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!
