CrockPot Breakfast Casserole

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:

  1. PREP: prep the veggies and dice the meat.
  2. WHISK: whisk the eggs, milk, dry mustard, and salt and pepper.
  3. LAYER: layer the hash browns, meat, onions, cheese, and peppers. Repeat, ending with cheese.
  4. 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!

  1. I am hoping to try this during 4th of July weekend. I’m tasked with making breakfast for the crowd. I’ve never made a breakfast casserole in a crockpot before so I had a few questions.
    It says to cook for six hours. Could I set it on low for 6 then it automatically goes to warm for maybe 2 hours, waiting for everyone to wake up, does that sound like that would be ok or do you think it would burn?

  2. I want to make this but I don’t have frozen hash browns, could I make fresh hash browns since I have potatoes? If so what would be the best way to prep the hash browns before forming the casserole?

    1. I haven’t tried this with fresh potatoes but my thought is that they would be more starchy. I would suggest shredding them and then soaking them in cold water for a few minutes to remove some of the starch. Lift them out of the water and drain. I have never tried it so I can’t say for sure. I think they would cook ok in the slow cooker but you might want to cook them part way in a non-stick pan and cool frist.

      Let us know how it goes for you!

  3. I had made this recipe last fall twice with refrigerated Simply potatoes shredded hash browns and it was great. I just made it today with frozen shredded hash browns and there is all this excess water. I realized it was the frozen hash browns that us the problem. Lesson learned.
    Also, I added dill which adds nice flavor as well. My family also enjoys the dish with green chiles in it.

  4. In theory this is a good recipe but it is very bland and lacks taste. I gave it two stars because if you season the potato’s with salt and pepper (at least) then this dish will be so much better.2 stars

    1. We have never tried this recipe in the instant pot but I hear the slow cooker setting works very similar to a traditional slow cooker so it should turn out. Let us know how it turns out Jordan!

    1. 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!

  5. I make it every Christmas. Waking up to that delicious smell is wonderful. My grandchildren love it. I use Bob Evans original sausage.

  6. 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?

  7. 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. :)5 stars

  8. 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 !!2 stars

    1. 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.

  9. 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!

    1. 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.

  10. 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.

  11. 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!

  12. 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

  13. 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? 

  14. 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?

    1. 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.

  15. 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!

    1. 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?

  16. 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?

  17. 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.

    1. 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!

  18. 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!

  19. 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?

    1. 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.

  20. 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.


  21. 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

  22. 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!
