Crockpot Breakfast Casserole

This Crockpot Breakfast Casserole is perfect for Thanksgiving or Christmas morning.  My family loves breakfast casserole and I always make it when our family comes in town to visit.  I love how EASY this recipe is! Trust me you will be happy you did!

Crockpot Breakfast Casserole

This breakfast crockpot casserole recipe is super easy to make and you can wake up to a delicious breakfast that is ready to serve right away!  I used a 6 quart crockpot and a slow cooker liner for this recipe to make cleanup easy.  I love how easy it is to prepare and really helps to free up an oven for holiday’s.

If you want to make this in the oven I am sure using a 9×13 you could bake at 350 for an hour. I haven’t tried that though because I like using my crockpot and keeping my oven free.

All you need to do is pour the coffee and orange juice and get out the plates and silverware. The kids loved this breakfast just as much as the adults!  Based on your crock pot you may want to start watching this at 7 hours to be sure it doesn’t get overdone.  I find that one of my crock pots heats a little “hotter” than another one.  You could also substitute any meat or make this a vegetarian option if you want!

I like to serve this with Breakfast Fruit Salad. Check out this slow cooker conversion chart as it helps to figure out if you are adjusting the time.

          Made this was delicious I didn’t want to go to store for green pepper and onion so used a can of Rotel tomatoes and Chile’s drained and squeezed out remaining juice with lid and seed with fork on all three layers, Wife says was awesome 👍

          1. To make this diabetic friendly what could I do about the hash browns??
            Newbie to this so I have a lot to learn!!

            Thanks~

        2. The store was out of frozen hash browns so i bought the diced frozen potatoes- i think it’s called potatoes o’brien. will this work or do you think it will get mushy?

          1. Yes it works! I have had to do that before too. You may need to reduce your time just a bit.

  1. What size of crock pot is it that you used? I couldn’t really tell by the picture if it was a standard size or a bigger one. Thanks!! .

      You could easily use fresh grated potatoes. Rinse the grated potatoes and then squeeze them with a dry towel to get excess water from the rinse out.
      Since this is in the pot for 7-8 hours, it is plenty of time fir the potatoes to cook.

  2. What is the serving size for this recipe? I was thinking of making it this week for a couple guests that will be staying with me. Thanks!

      This recipe worked out great for our family reunion morning. We were busy doing other things and my adult kids enjoyed it.

  3. What size is your crock pot? I have a larger sized one so assuming I can cut down on the amount of cooking time?

  4. I see both bacon and sausage listed as ingredients…but I don’t see in the recipe that you add sausage. Do you use both…or just one of the meats? Thanks for your help.

    1. @ J – I was wondering the same thing. I see cheese listed twice in the instructions, so I’m assuming it’s a typo and one of the cheeses should have been sausage?

      1. I made this last night for a bunch of ladies I was having over for breakfast this morning. I, too, noticed the error, but not until AFTER I had cooked both meats; decided to use both. Was really good! The only change I would make is to omit the green pepper, but that’s b/c I don’t like peppers to begin w/. Everything else was great.

        As for the size of the crock pot, a large one is necessary. There were 8 of us & approx 6 servings remained, so….it would be a great dish to make for a crowd….or, if you just happen to like having left overs. Definitely a recipe I’ll make again.

  5. I made this, last night, wish I would have checked on it throughout the morning… it was very overdone after 11.5 hours 🙁 black all around the edges and the flavors were very muddled. Next time I’ll try a few less hours.

    1. I cooked mine for about the same time; the bottom browned more than I would’ve liked, but didn’t get black. As for the flavors muddling, didn’t have that issue either–got great reviews. Hope you give it another try; it really is worth the time & effort of putting it together.

  6. Happy Thanksgiving! I just made this recipe for Thanksgiving morning and I haven’t tasted it yet but it’s only been cooking for 7 hours and its done!! It maybe because I have a brand new crockpot….but just wanted to share . The sides are brown seem a little too brown but I think it will be just fine. Also, I added red peppers and 1/2 of a jalapeño….I live in Texas sooooo gotta make it spicy!!

  7. What happened to the recipe for Crockpot Pizza Casserole?????
    I have been looking all over your site for it. I saw it the other day – today I was going to make it but it has disappeared.

    Thanks,
    Emma

    What a great Casserole to wake up to. Hope you are staying warm and cozy in this cold weather and thank you so much for sharing with Full Plate Thursday.
    Come Back Soon!

    1. Yes, I would think you need to watch it still at the same time as it will depend on your crockpot.

    1. I experimented and froze a couple of them I used freezer bags and froze them right in the crock for the slow cooker and then just lifted out the frozen casseroles and labelled them. I used one after a week, it tasted fresh and I didn’t have any overcooking issues. I used one after a month and it tasted just like the first one. My family thought it was delicious.

  10. Looks delicious. Going to treat my Family to this the next time they come. Thanks for sharing.

  11. Can you tell me aprox. how many cups or ounces of hash browns this needs? I don’t buy commercial hash browns, I make my own. Thanks! recipe looks amazing!

  12. Do I need to cook the sausage before putting it in the crackpot? I’m sure this is a silly question but I have never used one before.

  13. This looks delicious! I like what you mentioned about keeping your oven free, we’re the same way. We normally have a huge pot of breakfast casserole cooking over night and some monkey bread rising. Pop it in the oven, fix the coffee, and wait for folks to start lining up for breakfast.

    Thanks for the recipe, I’m saving it even for those (rare) lazy Saturdays I don’t want to fool with getting up early!

  14. I’m going to do a trial run this weekend to get the timing down. I’m hoping to make this Christmas morning for everyone when they come over! thank you 🙂

  15. Its just me and my husband. How would you suggest making this a smaller portion so i don’t waste a lot of food? Thank you

    I made this recipe last night to take to work today for my staff. It turned out AWESOME and was completely devoured. I used 6 quart crock and it only took about 5 hours on low. The edges and bottom were nice and crispy brown, while the inside moist and delicious. I sprayed the inside of the crock with cooking spray before adding ingredients and had absolutely no problems with clean up. I followed the recipe’s basic ingredient quantities and substituted cubed turkey ham and bacon bits for the meat part. I may have used slightly more milk, I just eye-balled it going in. I added one diced yellow onion with the green onion, added onion & garlic powder, dry basil, (salt & pepper of course) left out the diced pepper due to picky eaters. But seriously, the variations on what you could add to this basic recipe are endless!!! I will FOR SURE make this again!!! Thank you

    Thanks for this recipe. I took this casserole to a women’s breakfast. It was super easy to prep but I worry that the cook time was too long because it dried out and overly browned my edges- cooked per the recipe. I will make this again in the future and stick to sausage instead of bacon as I think the extra grease will add flavor and moisture. Will also sub yellow onions for part of the green peppers AND mix the ingredients before adding the eggs.

    1. I agree the sausage does add more moisture than the bacon – as we note on this recipe cooking times vary by crockpot.

  18. Recipe says to layer frozen potatoes, bacon or sausage, onions and I cup shredded cheese “in two or three layers”. Does this mean that you layer potatoes, bacon, onions, cheese, followed by another layer of potatoes, bacon onions, cheese, etc.? Sorry if it’s a stupid question but I want to be sure I do it correctly. Thanks!

  19. I’m making this for tomorrow as I don’t like to turn the oven on in hot weather ! Can’t wait! Thanks for posting this!

  20. I am thinking of making this for a dinner with my inlaws. Can I prepare it ahead and put in the refrigerator until time to cook?

  21. can swap out the milk for condensed cream of mushroom sot up (don’t add the water or milk that the can says) and if so would you mix it with the eggs or add it right before the eggs?

  22. I am wondering if I can shred fresh potatoes instead of using frozen hashbrowns? If so, how many potatoes would you suggest? Also – Do you think this would work with ground turkey instead of sausage or bacon? Thanks!

    1. Yes! To determine the number of cups in a 16-ounce bag, divide the number of ounces per bag (30) by the number of cups per bag (6) to get 5 ounces per cup. Then divide 1 pound (16 ounces) by the ounce-per-cup figure (5) to get a total of 3.2 cups per pound. Convert the decimal to a fraction to put it in measurements used typically in recipes, making it 3 2/10 cups, which reduces to 3 1/5 cups. Yes, you can use turkey sausage! Enjoy!

  23. I am super excited about making this tomorrow. I am just curious how well it reheats and stays good for. I usually make a breakfast casserole that we portion out to get us through most of the week.

    Was looking for an overnight breakfast to try for Christmas morning this year. Found this and looked very simple and very little prep. We always spend Christmas Eve at the inlaws out of state and always get home very late so this was perfect!! Took me few minutes to put together as I had cooked the ground sausage earlier that day and hit start on my crock pot. We woke up to the most amazing breakfast! Honestly this was our best Christmas ever. Not only did we enjoy an amazing breakfast together, we also did not have to be in the kitchen and miss our toddlers first ‘real’ Christmas as he opened his gifts and I tended to a newborn. Bravo! My husband thinks I’m a great cook and multitasker and really has no idea how easy this was for such an amazing taste.

      1. You think I could cook an evening in advance then warm it up the next day? Would that “ruin” it … warming it up ?

  25. If there are leftovers. Is it okay to reheat them? What is the best way to reheat them and how long do you use suggest keeping them for? OR do you have an alternative recipe if you would have cut it down to eat maybe for 4-6 ppl. Thanks.

    1. Oh yes, just reheat in the microwave. You could 1/2 the recipe and cook in a 4 qt slow cooker.

    Hi this is one of my staple recipes but this year we aren’t eating bread and potatoes. Anything I could substitute for the potatoes?? Thanks!!

    I’m making a breakfast casserole for church on Easter so I made this for home to see if it would pass the test. It got an A++.
    It was awesome. Everyone loved it. I made half the recipe and I thawed the potatoes first. The rest I followed exactly.It was done in 4 1/2 hours. Will definitely make again.

  28. I want to make this for our Sunday School class but it doesn’t start till 11:00am. If I start it at around 11:00 at night, 7 hrs would be 6:00am. Will it still be ok at 11:00 am?

    1. I do think so but I would consider doubling it or turning it to warm and checking to be sure it doesn’t get over done.

    We have our grand kids and parents over for a dinner every week. This week the kids requested a Breakfast for dinner. I came across this recipe and think I have a winner ! Thanks!
    PS: Clean up will be a breeze.

    I thought this was rather bland and a lot like other breakfast casseroles. It needed a broader flavor profile. I think that green chile would be a good addition to this and maybe onion. Also, I cooked mine for 6 hours on low and it was almost overcooked.

  31. I have been looking for a good slow cooker recipe for Christmas! This sounds like what i have been looking for but thinking of a few adaptations to work. Just wondering if they have been tried.

    1. Not a fan of shredded potatoes so thinking either frozen diced or fresh diced potatoes. Do you think one would work better then the other .

    2. We are not a fan of peppers and onions but I like the flavors it gives food so I am thinking instead of dicing them to slice them that way they can be picked around but still have the flavor. Do you think that could work.

  32. I added tomatoes, onions, green chilies, and a little jalapeño, then spooned this breakfast casserole into tortillas and they make delicious breakfast burritos. I also put the extra burritos in the freezer and it’s the best grab and go breakfast! My family loves them!

  33. Could I substitute the sausage with diced ham? If so, how much would you suggest. I am making this for my daughter’s homecoming breakfast and she is more of a ham eater than a sausage fan.

    1. I would just sure your slow cooker has enough room to cook and you shouldn’t have to increase the time.

  34. Delicious. I’ve made it in both crockpot and in the oven. It’s always a hit, regardless of basic substitutions. 5 out of 5 stars!

  35. I am considering making this for an event out of town. Do you think it would be ok to be turned off for half an hour toward the end then plugged back in and finished for the final hour?

  36. 5 stars
    I have made this so many times and it is always devoured! For larger things I have used a roaster and tripled the recipe and it still comes out perfect! Delicious recipe!
