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!
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
I think that would work perfectly.
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.
Thanks!
This serves 8. Any size of slow cooker will work. I use a 6qt slow cooker.
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?
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.
My mother-in-law came in town and this was a big hit. Even the kids loved it.
So glad everyone loved it!
Can you cook on high for 2 hours in crockpot
I haven’t tried it that way. If you do, I’d love to hear how it works for you!
I can’t tell from the pictures…. does it matter what type of frozen hashbrowns? Shredded, o’brien, etc.
I have made it with both shredded and diced hash browns. Both work perfectly.
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!
I haven’t tried it with russet potatoes so I can’t say for sure. I *think* it would work though.
Could you double the recipe ?
We are looking to feed more than 8 people for a brunch
Thanks!
I would not suggest doubling this recipe as it would likely not cook through.
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.
I’m so glad your family loved this!
Approximately how much salt do you end up adding?
I usually add just over 1/2 teaspoon.
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?
I think it should be just fine on warm. The eggs are mixed with milk which softens them slightly.
How many will this feed?
This recipe should feed 8 people.
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!
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?
Hello, I was curious if you know anyone that has tried egg substitute like EggBeaters? Thanks.
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?
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.
Hello. Im curious what the white substance is in the pic. Sour cream?
It’s a little bit of the egg white that wasn’t stirred in.
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?
That sounds like a great addition to the recipe and would give it a nice addition of color!
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
I have a delicious breakfast casserole in the oven here:
Breakfast Casserole with Sausage
and this one is delicious as well Overnight Breakfast Casserole
Would this be ok to mix the night before and put in fridge?
Yes, that will work just fine!
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!
It is added in step 2.
