Crock Pot Breakfast Casserole is perfect for busy mornings! Tender potatoes, fluffy eggs, and savory sausage cook up overnight in the slow cooker. Delicious!
Crock Pot Breakfast Casserole
This Crock pot Breakfast Casserole is my go-to when I have overnight company. The eggs cook up light and fluffy all around the ingredients, so it’s basically a giant omelette once it’s all baked. This breakfast casserole is so easy to whip up the night before and then let the slow cooker do the work while we all sleep. Then guests are greeted to fragrant breakfast smells first thing in the morning and you get all the credit for serving a delicious breakfast. It’s so great for Christmas Eve, busy Sunday mornings or anytime you want a big family breakfast but don’t want all the fuss.
Tips for Crock Pot Breakfast Casserole
- If your crock pot cooks hot or if you have an oval one (like the one pictured above) it may only take six hours on low. So you may have to stay up a little late the night before to start the cooking process. But if you’re like me, it’s way easier to stay up late and visit with company than it is to wake up early and make a big breakfast.
- If you want to swap out sausage links for bacon, crumbled turkey sausage, diced ham or any other meat, by all means! Or add them all together for a meatier dish. Anything goes!
- You can also add diced green or red peppers, onions, pepper jack cheese, jalapenos, chopped spinach leaves, anything you want! That’s the beauty of this recipe; it’s so versatile you can make it your own with any number of ingredients.
- Try topping this casserole with salsa, sour cream, cilantro, diced tomatoes, green onions or more cheese!
What to Serve with Crock Pot Breakfast Casserole
This casserole is a terrific all-in-one dish, so you could serve it alone with some toppings and a side of fruit. Or pair it with our Make Ahead Breakfast Parfaits, our rich Blueberry Cream Cheese Coffee Cake or a batch of the BEST Blueberry Muffins.

November 12, 2012 at 9:49 amThis looks amazing! Do you think it would work to add bacon?
Erica says
November 12, 2012 at 2:44 pmAbsolutely! I have made it with bacon and it is awesome
Mike Ricksecker says
April 17, 2014 at 3:20 pmEverything works when you add bacon!

Haley says
December 5, 2012 at 3:22 pmIf i was to double this would it over flow in the crockpot? Im cooking this for co-workers and need to serve aboit 12?
Erica says
December 5, 2012 at 8:49 pmuh yeah.. I would do 2 crockpots!
Regina Key says
December 6, 2012 at 6:41 pmI am the worst at cooking sausage link. I think I’ll be cooking half a package of sausage (crumbling beforehand) instead, add some bacon, and fresh herbs. This looks great!! Can’t wait to try it!
Jen says
December 10, 2012 at 10:06 pmA trick to cooking links is to start them in some water and let the water boil out of the frying pan (like pre cooking bratwurst). Once the water is gone just brown the links.
Betty819 says
March 25, 2014 at 6:10 pmThis is how my DH cooks his sausage links and I’ve been criticizing him about that method, but guess this makes sense. Basically you’re steaming the sausage links first, then browning them off. Sausage links don’t agree with me anyhow; but bulk sausage fried, I have no problem with digesting it.
bonny says
September 23, 2015 at 7:09 amI always cook my sausages (like my bacon) in the oven….put them on parchment paper and cook at 300 til browned….so easy and a lot less mess. I always cook the full pkg then wrap what isn’t used in paper towels and refrigerate.
sarah says
December 8, 2012 at 6:13 amHow many hours do you set this for??
sarah says
December 8, 2012 at 6:14 amNever mind, I just saw that part. I was focusing on the ingredients and totally missed the cooking time. Sorry guys!
sherry says
December 9, 2012 at 11:48 amI noticed that if we want to double it you said to use two crock pots? Why?
Can’t I just double it and add time? Just asking I am not crock pot friendly….lol !
Erica says
December 9, 2012 at 12:37 pmIf you can double it and make it fit in one crock pot, by all means go for it. We have a big crock pot though and I think if we doubled it, it would be close to overflowing… I would only maybe add an hour or two for cooking it if I kept it in one crock pot. It’s not the cooking I would worry about.. It is making it all fit.
Diane Johnson says
December 19, 2012 at 11:56 amFor food safety, it’s best not to fill your crock pot above 3/4 full. Having too much in the pot will make heating the food take too long to get to temperature and bacteria (that’s naturally in the food) will grow before the temperature can prevent it. Two crock pots would be best. You don’t want to serve food poisoning with your meal. A longer cooking time would not solve this problem, since it’s a matter of the heat getting to the center of the food quickly.
Katie says
December 9, 2012 at 9:13 pmDo you think you could cook and freeze in sections?
Erica says
December 10, 2012 at 8:22 amI wouldn’t. Eggs really don’t freeze well.
Carla says
December 18, 2012 at 6:37 pmI freeze eggs all the time and they freeze well and this probable will to.
Arlene @ donteatdirt.com says
December 12, 2012 at 6:24 amThat sounds delicious. I’ll have to try it.
I usually do overnight oatmeal for the work week mornings, this will make a nice switch.
Jenna says
December 13, 2012 at 12:31 pmWhat size crockpot are you using?
Erica says
December 13, 2012 at 7:25 pmIt’s a 6 quart.
kim says
December 13, 2012 at 5:07 pmI was wondering about the texture of the eggs. Are they kind or hard or soft?
Erica says
December 13, 2012 at 7:21 pmThey aren’t runny at all.. I would say they are on the well done side.
Phyllis says
December 14, 2012 at 12:05 amI’ve enjoyed this many times…not cooked in a crock pot though. Sounds amazing. Using bacon also sounds good. Thanks so much for sharing!
Jenna says
December 16, 2012 at 6:33 amLooks great! Did you thaw the potatoes first or toss them in frozen?
Erica says
December 16, 2012 at 5:31 pmI kept em frozen
Kay says
December 17, 2012 at 10:21 pmHmm…. got back from the store and noticed the bag of potatoes o’brian I got is only 1 lb… I didn’t see any bigger bags at the store. Is 2 lbs. the correct amount?
Erica says
December 18, 2012 at 8:17 amI used a 2lb bag but you can use a 1lb and it should still be fine.. Or two 1 lb bags works too
Stacy says
December 18, 2012 at 11:18 amDo you think this would work with chicken apple sausage or some other type of chicken sausage?
This sounds great, I am going to try it this weekend!
Erica says
December 19, 2012 at 7:40 amSure! Why not? Come back and let me know how it turns out.
Karen says
December 18, 2012 at 4:44 pmSounds and looks delicious!! Could I program my crock pot to switch to warm after 6 hours? Or would the dish dry out? How long do you think it could sit on warm safely? Would love to make it for Christmas morning. Guess I could assemble, store in the fridge and wake at 1 am to put in the crock pot.
Thanks for the great recipe!!
Erica says
December 19, 2012 at 7:39 amI don’t know how long it would stay good on warm. I am guessing a few hours on warm would be ok.
Jill says
December 18, 2012 at 5:09 pmHas this receipe ever been halfed. It sounds like it makes a lot and I would love to try it but cut it in half. Thanks.
Erica says
December 19, 2012 at 7:37 amYes you can but it will cook faster. Just adjust your times and check on it every hour or so
Carla says
December 18, 2012 at 6:39 pmThis sounds really good and can’t wait till our hog comes to make this.
Jessica Perez says
December 19, 2012 at 1:13 pmCan I used pre cooked sausage links instead of the ones that need to be browned on the skilet?
Erica says
December 19, 2012 at 7:39 pmSure! I’m sure that would be fine!
Deidre says
December 20, 2012 at 6:23 pmI’m going to try bacon instead of sausage. So would I need to cook the bacon before placing in crockpot or could I use the microwave bacon? And do I need to break it up in pieces to put in the crockpot, sounds delicious! Thank you!!
Erica says
December 21, 2012 at 11:43 amDefinitely precook the bacon.
Mary Jo says
December 21, 2012 at 8:42 amCan you do this without the potatoes and if so would it be less cooking time??
Erica says
December 21, 2012 at 11:44 amI’m sure you can.. It would lose a lot of substance though!
Kristian Sharp says
December 21, 2012 at 11:34 amDo you think I could use french bread instead of hashbrowns?
Erica says
December 21, 2012 at 11:42 amI’m sure you COULD.. Can’t promise how it will turn out though!
Mande says
August 24, 2013 at 12:58 pmDry bread works best. I buy seasoned stuffing cubes. It’s how we make Christmas morning baked eggs 🙂 And it’s delish!
Katy says
December 22, 2012 at 1:45 pmJust wondering if you can add biscuits to the top? I’m gonna do this for Christmas.. looks yummy.
Erica says
December 24, 2012 at 10:09 pmYou could sure try it!
Jennifer says
December 22, 2012 at 10:05 pmI was wondering if it would work with fresh potatoes, onions and peppers instead of the frozen potatoes o’brian? If so, should I alter the recipe in any other way (i.e. when to put them in or cooking time?)
Erica says
December 24, 2012 at 10:10 pmI’m sure it would be fine! I wouldn’t alter the cooking times or anything
Heather says
January 16, 2014 at 6:03 amHow did the fresh potatoes work out for you?
Ann says
July 31, 2014 at 6:29 pmThats what I did. I baked russet potatoes and chopped onion and green pepper from my garden. was going to throw in some garlic but making it for people at work so I thought not.
Echo says
August 1, 2014 at 9:00 amHaha! Leaving out the garlic was a smart idea – especially with tight work spaces. Nothing is better than fresh from the garden! We’re glad you liked the recipe!
Stephanie says
December 23, 2012 at 6:02 pmCould you cut Time in half and cook on high?
Erica says
December 24, 2012 at 10:09 pmNever tried it. Let me know if you do it and how it works out!
hayley says
January 22, 2013 at 7:44 pmWhat if you have mini crock pot like a 2.5 or 3 quart? I’m only trying to make this for 2 other people…. I’m sure i can figure out how many eggs/milk/bacon etc to use to fit my crock pot..but I’m worried about cooking time! i sure don’t wanna over cook/burn it! I’ve seen people make breakfast casserole in a crock pot before and the eggs almost turn out grey/brownish from overcooking.
Erica says
January 24, 2013 at 10:07 pmYikes. I for sure wouldn’t cook it as long. I would say the first time you do it, keep your eye on it. Then let me know how it turns out!
Pat says
March 11, 2013 at 7:44 amCan you double the recipe in the crock pot?
Erica says
March 11, 2013 at 8:12 amYou would need a HUGE Crock Pot, but sure! I have a pretty big crock pot (the biggest you can buy at WalMart) and if I doubled the recipe it would definitely overflow.
carolyn says
April 20, 2013 at 3:46 pmhow many calories per serving
Erica says
April 21, 2013 at 8:54 amI think we have this recipe in MyRecipeMagic.com. It has the calories and everything there… lol, you may not want to know!
AJH says
July 11, 2013 at 1:48 pmdo you stir it at all throughout the time in the crock pot or just let it cook?
Erica says
July 11, 2013 at 2:46 pmNo… you just leave it. You just let it cook.
Ashley says
August 3, 2013 at 9:04 amMade this last night and had it this morning… My kids were not impressed with it. And I wasn’t a fan either.
Michelle says
September 1, 2013 at 12:57 pmDo you think that Rotel would be ok to use rather than a tomato?
Emily says
September 4, 2013 at 7:57 amSure, just be sure to drain the excess juice from the can.
Anna says
September 9, 2013 at 9:36 amIs that slow-cooker insert one that was purchased separately? It doesn’t look like the black oval inserts for that type of slow-cooker. I broke my insert and wasn’t sure if I should toss the entire unit or not. If it is separate, do you know if it is lead-free? Thanks!
Erica says
September 9, 2013 at 5:51 pmIt is actually the one that came with it… sorry! I don’t know what to recommend you do
Erica says
September 9, 2013 at 5:51 pmIt is the one that came with it. I don’t know what to tell ya!
Deanna says
April 22, 2014 at 11:33 amShould be able to go to the website for the manufacturer of the crock pot and see if you can order a replacement.
Alice says
September 17, 2013 at 9:30 amHas this ever been cooked with just regular russet potatoes either cut up in small chunks or shredded? I don’t have any hashbrowns on hand and am looking for a breakfast dish for supper tonight. THANKS!!!
Debbie says
December 3, 2013 at 12:14 pmCan you use canned diced tomatoes?
Erica says
December 5, 2013 at 10:42 amYou can… I just prefer fresh!
Jodi Neil says
December 22, 2013 at 9:26 amI just made this last night. Everyone liked it, except me. I didn’t like the texture of the hash browns in it. I used 2 pounds of pork sausage that I cooked up first, that was great! I sprayed the crock pot with Pam first and it came out very nice. I cooked mine of low for 9 hrs. and it was a little too long.
Sue Lierle says
December 23, 2013 at 7:08 pmI am always so amazed at all the goofy questions people ask about recipes! People this is the recipe she has and uses, she doesn’t do all these weird things you are asking. If you want to know if something can be changed, then change it and let her know if it can. Do any of you know how to cook? You be the ones that experiment and tell us if it works. She knows her recipe works and she likes it the way it is I am sure. By the way I make my own version of this but I mix in cut up biscuits and bake in the oven. This is very easy to make it your own by adding or not adding whatever you would like. I often leave out the hashbrowns. Bake it until you think it is done. You should be able to tell when it is, if eggs are done, biscuits, are done or whatever if you know anything about cooking. People cooking is like experimenting! Thanks for letting me get this off my chest, always amazes me at all the goofy questions, and how just because someone submits a recipe they are suppose to know how many different way it can be changed, what do they think you try all these different things?
Heather says
January 16, 2014 at 6:13 amWhen someone posts a recipe, I think they expect questions and might even welcome them. Your comment could possibly make someone with very little groceries embarrassed to ask if something can be substituted, added, left out. This could ruin their meal and waste money. Getting something off YOUR chest may help you but burden someone else.
Megan says
November 24, 2014 at 11:45 pmHaha, Sue I just read all these comments/questions and thought the exact same thing! SO many questions, so many weird variations, hah!
Planning to make this soon can’t wait to try it! Thanks! 🙂
Heather says
September 12, 2015 at 11:06 pmI have used this recipe many times, it always comes out great. I do have to cut the time back as I have an oval slow cooker, and it’s not very slow! I also add bacon, and sometimes sausage gravy. (which is very good, but even more fattening!) Thanks for the ‘comfort food’ breakfast idea, my family really enjoys it!
Emily says
September 14, 2015 at 12:16 pmYou’re welcome! So glad you like it.
Misty says
December 22, 2015 at 9:27 amHas anyone tried it without eggs? I have a bunch of people coming for Christmas breakfast and this would be great. But I have a couple people who don’t eat eggs. Any suggestions? Thanks!
Erica says
December 31, 2015 at 10:42 pmYou will definitely want it with eggs so it cooks right… can they have egg substitute? That might work..
Maria says
December 21, 2017 at 4:36 amHash Browns frozen or thawed?
Favorite Family Recipes says
December 23, 2017 at 10:51 pmEither one works 🙂 Frozen is easier but if you have thawed, that works too!
