Oh my goodness-your breakfast casserole looks so YUMMY! Pinning so I can try your recipe next weekend for a family gathering!
I’m not usually a breakfast casserole maker, but this looks so simple and lovely. I’m sort of also considering making it without the eggs (maybe add some cream instead or something for that layer) and then serving it with customized eggs the next morning.
If I cut the recipe in half does it still need to cook the full 8 hours?
I’ve never tried it, but I would think you would want to cut cook time to 4-6 hours. If you try it, let me know how it goes!
This looks amazing! I may just do one meat instead of 2 but it looks great! Thank you for the recipe, I will be trying it for Christmas morning. One question, how long would this keep in the fridge or could I freeze any leftovers? Thanks again!
Did you cook yours on high or low? Making this for xmas brunch and I don’t want to mess it up!
Definitely Low, if you’re making it overnight.
Do you cook the sausage first or let it cook in the crockpot? Looks so yummy! Going to try it!
Sausage should be browned ahead of time. Let me know if you have any more questions!
I made mine using a crock pot liner bag. If you use a crock pot liner you can carefully lift the casserole out of the crock pot and put it in a dish–bag and all! I needed a disposal dish to take this dish to a pot luck and this was a good solution. It will be easier if you use a 2nd set of hands when lifting.
That’s a great idea, Mary. Thanks so much for sharing!
God Bless whoever invented crock pot liners. Thanks for that reminder/tip.
When you made it for pot luck did you still cook it over night? Our pot luck starts at around noon.
So does the bacon and sausage need to.be fully cooked beforehand?
Yes
Making this right now for breakfast tomorrow morning. Will report back about how it goes. Making recipe as is but may add some garlic powder to my eggs.
I plan on making this for a bridal shower brunch, how long do you think I could leave this on the warm setting? And do you think I could cook this longer, than the 8 hours, on a low setting without the eggs over cooking? Any other tips will be much appreciated! Thanks!
I think the eggs would probably over cook if you added any cook time to it. I haven’t done it with this recipe, but in the past I’ve cooked a recipe *almost* all the way (so like 6ish hours). Then refrigerated until I needed it. Then cooked it for the remaining cook time, plus an hour (that would be 3 hours for this recipe) to account for it being cold from the refrigerator. That might work.
And for warming, I’ve had it set for warm for 3 hours, and it was okay then. I would just try to keep an eye on it.
Was very exited about finding this recipe! I’m all about convenience so I opted for the fully cooked sausage crumbles from Jimmy Dean. I made this for brunch Sunday afternoon but was worried about the cook time since my crock pot does cook hot at low. I wanted to serve at 11:30, so I got up at 4 am to start it. I put everything in the crock pot ahead of time except the egg mixture. I used 1 bag of Simply Potatoes (shredded), 2 bags of Jimmy Dean Meat Lovers Sausage/Bacon crumbles (fully cooked). 1 chopped onion, and 2 cans of mild chopped green chilies instead of the bell peppers and layered everything per the instructions.. It was ready to eat in 6 hours, so I turned it on warm and lifted the lid, the edges were getting dark. I heated flour tortillas and offered fresh salsa and sour cream to make breakfast tacos! OMG – this was a huge hit with my guests! I used a 6 qt oval Crock Pot and I will only plan to cook it 6 hours next time, and there will be a next time. Thank you!
Just an observation: My experience mirrors that of Ms. Chavez. I suspect that six hours is sufficient as I left mine for eight and it burned a fair amount of it.
I love breakfast casseroles and traditionally make them in the Oven. I just made this last night. My spouse has a lot of group breakfasts for work and leaves around 5:30 am. I figured this would spare me the time of getting up at 4am and cooking. I timed it to be exactly 8 hours on low. I woke up with 29 minutes left on the count down and it smelled a little burnt. I checked the sides which had separated from the cooker and they were burnt. I ended up making a 2nd casserole with the leftovers for her to take to work. I don’t think I would try this again for a work function… maybe if it was just with family.
How many calories in a serving of this delicious casserole?
I don’t provide nutritional information, but you can always plug it in to a calorie calculator to find out.
Can this be easily transfererred to an aluminum pan in the morning for serving at a teacher breakfast?
I would honestly say no. You’ll kind of lose the layers and since it cooks in the crock for so long the casserole is in the shape of the crock.
Do you think this could be made using hash brown patties??
I think that would work. I would just sub out the shredded hash browns and make a double layer of the patties in the bottom. If you try it, let me know how it turns out!
Good recipe. I definitely agree that average cook time is more like 4-6 hours on low. I tried to set it for “overnight,” cooking it about 6.5 hours and the edges were overdone and recipe overall a little dry. I will try it again and tag team with my insomniac husband for a 5 hour cook time – turning it either on or off in the early morning hours.
Forgot to rate it. I’ll say “3 stars” until I get the cook time settled.
I made a version of this yesterday (basically the same, but different type of potatoes) as a dry run before Christmas morning breakfast. It was very good, but it only took 3 hours to cook and that was on low. My Crockpot is not a hot cooker either so beware of the cooking time! I’m going to make it for our breakfast for sure, but plan on keeping a close eye on it. Thanks for sharing your recipe!
Do I need to defrost the hashbrowns first? Or put them in frozen? Can’t wait to try this for Christmas Morning tomorrow it looks delicous. TIA!
This has all of the breakfast ingredients we love and looks delicious. I LOVE that it is done in the crock pot! Yay!
This is a great recipe! I have made this dish twice for a group of hungry high school swimmers. These boys devoured it each time! It’s a big hit And, the house smells wonderful in the morning after cooking all night in the crock pot. We will definitely serve this again and again!
I made this Easter morning for Church sunrise breakfast. It was perfect with 1 slight change. I did put 2 tsp of dried mustard. I made it before Easter and it seemed like it was missing something. Other recipes called for dry mustard so I added. I have a Hamilton Beach slow cooker with a temp probe. I set it for 155 degrees on low. It was done in about 3 hours and held warm until I left for church. I have also added 1 cup of salsa and it was very good . Great recipe. Very versatile.
How many would this serve?
I made the overnight crockpot breakfast recipe for work. Everyone loved it. Thanks I plan to use again with my family for the holidays.
This recipe served 10-12 people. Everyone at work loved this recipe.
Planning on making this for brudal shower brunch. Can I double the recipe and how long should I cook it? Thanks
This recipe is already pretty large. If you doubled it, you’d likely just need 2 crockpots.
This looks so good!! I’m going to make this for those busy school day mornings!
Hi,
If I wanted to make it without meat, is the cooking time the same? I am planning to make 2; one with the meats and the other without.
Thanks in advance!
There’s not much meat in it. The cooking time will be similar, maybe a little shorter.
Sort of a newbie crockpot user here. If I leave out the hashbrowns and just use meat, peppers, eggs and cheese what do you think about cook time? Really just eggs cooking at that point.
Would this work in a conventional oven. 350 for how long?
I’m not sure as I’ve never tried it. Let us know how it goes if you try it!
Made this last night exactly as written and this morning it turned out delicious! I cooked it on low for 6 hours with no burning. Thank you!!
Can you make this oven in baking pans? Has anyone tried that?
I have older oval crockpot or slow cooker so no timer or auto shutoff. Not an early morning riser either!
I’d like to serve around 9 a.m. I’m getting from above comments it will be overcooked if I start it at midnight or 1 a.m.
What’s my solutuion besides not serving it?
My Crock Pot that I made this in is also an older model (8-10 years old) and also oval. No auto or timer or anything, and it was fine on the full 8 hours. I’m guessing for those that it’s over-done, they have newer and/or hotter crock pots! So I personally would be fine turning it on at 12 or 1 and having it be done between 6-8am (you can turn it off or to warm at that point since it will still stay really hot as long as it’s still in the crock). If you’re really worried about it, I also have this super easy to throw together egg breakfast casserole. Our family has been making it for as long as I can remember, and it’s really yummy. https://www.thegraciouswife.com/easy-egg-breakfast-casserole/
Can the ingredients be put into the crock pot and then put in the refrigerator until it’s time to start cooking? If it only takes 3-4 hours to cook, I would have to start cooking it around 2 a.m. in order for it to be ready in the morning and would like to have it all put together first.
Yes, you can do that!
could you use croutons instead of hashbrowns?
No, I don’t think that would work.
Do you need to thaw the hash browns?
Nope! You can dump them right in!
How long will this keep in the fridge after it’s made?!?!?!
I’ve never kept it longer than 2-3 days because it’s always gone by then. But I would say up to 5 days covered and refrigerated.
Hi . . . In the body of the recipe, it states to mix the milk, salt, pepper, and sugar, however, the list of ingredients does not include sugar? It includes sour cream. Was the sugar in the body of the recipe a mistake? Thank you.
Hi Debbie, I’m currently in the process of re-vamping the recipe to make it even better, but I haven’t totally updated the directions yet. I will when I’m done here. I got rid of the sugar entirely, and added sour cream to the egg mixture to make it more moist.
