Crock Pot Breakfast Casserole


Crock Pot Breakfast Casserole is the perfect breakfast for feeding a crowd. Hearty and so delicious!

Can you believe Thanksgiving is just over a week away?!

Usually my family and I kick the holiday off by watching the Macy’s parade with cold mimosas in one hand, and Mini Cinnamon Rolls in the other before getting into our annual showdown over playing Scrabble, followed by feasting on my Mom’s traditional Thanksgiving dinner later that afternoon. I am not mad at that!

The men don’t last too long on cinnamon rolls alone though (and need something to soak up all those mimosas!) so usually I’ll bring over a breakfast casserole I’ve prepped the night before, or my Dad will whip up some eggs and bacon for everyone to eat. We’ll fill in the cracks with apps, homemade Chex Mix, and my Dad’s famous Bloody Marys until the big meal is served later that afternoon.

This year, however, we’ve got a more concrete game plan. Instead of nibbles and nips of this and that, I’m bringing over a big Crock Pot Breakfast Casserole to feast on all morning long.

This crock pot breakfast casserole is so good that my Mom has made it twice in the last month, first when my Grandma and Aunt were in town and again a couple weeks later for Evie’s baptism, then I made it for Ben and myself last Saturday morning to eat and reheat all weekend long. We seriously cannot get enough!

It is such a crowd pleaser, not to mention could not be simpler to make. Just layer frozen hash browns, breakfast sausage, eggs, and shredded cheese in a crock pot, then let ‘er rip. Perfect for throwing together on Thanksgiving morning, then cooking on high for 4 hours while everyone gets up and at ’em. You can even cook it on low for 8 hours overnight, if the gang’s getting started early!

Start by spraying a large crock pot with non-stick spray then spreading half a 30oz bag shredded hash browns in an even layer on the bottom.

Next add a layer of 1/2lb cooked breakfast sausage,

Followed by 4oz each shredded cheddar and mozzarella cheese.

Top with 3 sliced green onions, then repeat the hash brown, sausage, and cheese layers one more time.

Finally, whisk a dozen eggs with 1/2 cup milk, salt, and pepper, then drizzle the mixture over the casserole.

After that, just set it and forget it! 4 hours in the crock pot on high, or 8 on low, and you’ll have got yourself a fluffy, filling breakfast casserole that your entire family will love.

    This sounds delicious!! Thank you for sharing! Is there a way to cook on low so that you can cook it overnight?

    • Angel 08.28.2015

      It says you can cook it on low for 8 hours = overnight.You could always put everything together in the crock ahead of time and then put it in the fridge (keep covered). When you’re ready to go to bead, pop it into the crock pot cooker and set it on low, but give it an extra hour’s time because all the ingredients will be chilled, including the crock. If you want it ready for 9 a.m., put it on at midnight. If you want it ready for 7 a.m., turn it on at 10 pm. Adjust as needed.

  2. Mary 11.13.2012

    I’ve made a variation of this casserole a number of times. I like to saute some onion and garlic to add to it. And when I a am feeling really decadent, I use sausage AND bacon!!

    And I LOVE Ziplist — I’ve been using them for a long time now. I’ve stored quite a few of your recipes in my recipe box.

    • Mary 11.13.2012

      Oh, I meant to add that I cook the casserole overnight on low. Talk about waking up to the smell of yummy breakfast!!

  3. Casey 11.13.2012

    This looks soooo delicious, I want to make (and by that I mean eat) it asap! Any recommendations for a similar recipe for potato-haters?

  4. I’m so glad you posted a recipe like this. I’ve seen these breakfast crockpot things all over Pinterest and was curious as to how it would turn out. Looks delish!

  5. Such a great idea! I tend to get stuck in a soup rut with my crockpot most of the time. It’s so convenient though I REALLY need to start making other meals with it!

  6. Ed 11.13.2012

    Wow that looks great for the weekend!

  7. young c 11.13.2012

    thanks for sharing! sounds delish!

  8. Trisha 11.13.2012

    Yep. This is happening. We open gifts with my parents Christmas morning & it never fails that we all get the munchies & my mom feels like she needs to whip up breakfast even though she’s always prepping for dinner for our extended family later in the day. This year, I’m going to do this so she doesn’t have to think twice about it!
    Thanks for sharing!

  9. B 11.13.2012

    the Apple Chicken recipe is linked to the Save Recipe button on the breakfast casserole – at least that’s what it says every time i try to save the breakfast casserole recipe. Thanks

  10. This would also be perfect for Christmas morning! Love the new feature too!

  11. Lauren 11.13.2012

    I almost did a crock pot breakfast casserole last Christmas but I wasn’t sure how eggs would do in the slow cooker. Glad to see this turned out. I may need to give it a try!

  12. Bridget Montgomery 11.13.2012

    A couple of questions….

    -Do you think it would work with egg substitute?

    -Do you use crock pot liners?

    • Iowa Girl Eats 11.14.2012

      Neither my Mom nor I have tried, but if you do, I think it might take a little less time (just a hunch?!) Also, I don’t use CP liners, but you certainly can!

  13. I am loving the addition of ZipList. I definitely need more organization in my life. My computer thanks you too! :)

  14. lisa 11.13.2012

    Ha, ha, awesome! I was just pondering what on earth I was going to do for Thanksgiving breakfast… and its gonna be this! Yay!

  15. Candy 11.13.2012

    This breakfast casserole looks great and I love that you have partnered with Ziplist to make it easier to save the recipes that I love (and I sure have a lot of them). I usually have to go into your site and search….thanks a bunch!

  16. Christie 11.13.2012

    Omg!!! Looks amazing!!!

  17. Lisa 11.13.2012

    OMG you just made my Thanksgiving morning!!! This is HAPPENING, along with Pinch of Yum’s chocolate glazed baked mini donuts. Seriously, let’s just forget dinner …

  18. Bek @ Crave 11.13.2012

    Love the Ziplist thing! How convenient- your so up with the times and technology ;)

  19. Michelle 11.13.2012

    Your Thanksgiving routine looks so relaxing and wonderful! We are tackling three parties. Lots of energy required!

  20. I just made something similar to this last weekend! It didn’t turn out, though :( I cooked it 7 hours on low overnight and it got all dried up… and crispy on the sides. My 4 year old niece said it best when she looked at it and said “that looks yucky”. I’m not sure what I did wrong but I want to give your version a shot! Maybe my crock pot just cooks too hot….

  21. Kristin 11.14.2012

    This is great and will be perfect for Thanksgiving morning! Thanks so much!

  22. I’m always looking for good breakfast casserole recipes, and I’m always looking for good crockpot recipes. Hence, I LOVED this post. I can’t wait to try this recipe. :)

  23. Love this breakfast casserole!! I make a similar recipe (but with bacon) for special occasions and it comes out great!! I want to warn you though NOT to try shredding your own potato and using it in this recipe (except if maybe you cook it for first). Even if you try squeezing it dry, it won’t cook up well in the slow cooker (not that I’d know from experience or anything! haha).

    • Sara 11.14.2012

      Thanks for the tip about the potato Chelsea. I live in New Zealand and we don’t have anything as impressive as those shredded hashies looked in the picture and I was going to grate some potato but now I won’t bother! I will just try pulling our usual hash browns apart. Cheers :)

  24. This is sooooo perfect. I’m making this this weekend. Can’t wait. I’m going to use chorizo in place of the sausage for some extra kick. Thank you!

  25. Lisa 11.14.2012

    Yummmm, looks delish! My friend has been telling my how great Ziplist is also. Guess this is now my time to try it out!

  26. Love the ease of this – too bad Thanksgiving has already passed here in Canada, but this could be a top contender for Christmas morning!

  27. I have to admit, I’ve always been afraid of breakfast casseroles in the crock pot, thinking they would burn. But yours sure looks like it won’t! I will have to try!

  28. Brandy 11.14.2012

    This looks good, but since I am not going to be feeding any large amount of people soon, I wonder if I can cut it in half, like just do one set of potato, sausage, cheese layers? Would you adjust the cook time?

    • Iowa Girl Eats 11.14.2012

      I would adjust the cooking time to 2 hours or so on high. Might just need to watch it to see when it’s done!

      • Brandy 11.15.2012

        Thanks! I am making it this weekend :)

        • Chris 01.07.2013

          Did your cutting the recipe in half and changing the time to 2 hours on high work? I want to make too, but for smaller group.


      • Amber 06.25.2013

        This looks SO good. I cannot wait to try. Do you think that it would work to cut the recipe in half and cook on low for 4 hours? I only need to feed 4 people, and if I could throw it in before church and it be almost done when we get back, that would be amazing. Thoughts?

        • Iowa Girl Eats 06.26.2013

          Hey Amber! I’m not sure as I’ve never tried. I don’t see a HUGE problem with doing that it, but let us know how it turns out!

  29. Tracy 11.14.2012

    Love this recipe! Do you have any thoughts on baking it in the oven? The reason is 8 hours is not enough time for overnight and 4 hours is too long in the morning for our schedule.

    • Iowa Girl Eats 11.14.2012

      I’m sure it could work! Maybe 350-375 for 45 minutes to an hour?! Let me know if you give it a try!

      • Bill 08.02.2013

        Works just fine in the oven at 350 degrees for an hour.

    • Jimmy 12.20.2013

      You can always plug your crockpot into a timer , I used a timer that we had been using to cut our Christmas lights on and off . It worked great .

  30. ErikaMC 11.14.2012

    I’ve been using the Catch app on my phone and computer to save all the recipes I like but I will have to try ZipList and compare.

    I kinda miss your daily breakfast posts and hearing about your walks with your mom? More breakfast posts please :)

  31. Katie 11.14.2012

    Anyone have thoughts on how this would work with morningstar breakfast sausages instead of sausage – I would worry about it drying out, but could put it in frozen. Let me know what you think! This looks amazing!

    • Iowa Girl Eats 11.14.2012

      The original recipe from Jimmy Dean called for pre-cooked sausage crumbles, so I bet it would work fine!

  32. Susan 11.14.2012

    I love using Ziplist! So glad that you’ve added to your blog~

  33. This is sound a great idea! My family will love it!

  34. Diedre 11.14.2012

    I LOVE using Ziplist! So excited you’re pairing up with their app and website!

  35. Sara 11.14.2012

    Could you specify what is considerd a “large crockpot.” The one in the picture looks similar in size to mine, but I am just wondering if you know how many quarts yours holds.

    This looks amazing and I am going to try it soon!

    What time of sausage did you use? I went to my local Jewel and they have garbage! All with msg, etc. Costco has all natural, but you know Costco…everything is BIG! So now I have a ton of sausage I have to use up! Ideas?

    • Iowa Girl Eats 12.03.2012

      I actually don’t remember what brand I used! If you have a ton leftover from Costco, I would portion it into 8oz portions and freeze!

  46. […] Essentially you just layer 1/2 bag of frozen hashbrowns, 1/2 package cooked sausage, 3 green onions, and 40z each cheddar/motz ~ and repeat.

  48. Made this and the mini-cinnamon rolls this past week and they were a hit! Thanks for the great recipes! Gave you a little shout-out on my blog too.

  49. Janet 02.03.2013

    I’ve baked similar casseroles in the oven, one made with French bread instead of hash browns and the other made with grits. I’d try the French bread option.

  50. Jo 02.12.2013

    This sounds great. Are the hashbrowns thawed out or frozen?
    Thanks, Jo
