Slow Cooker Breakfast Casserole


I actually didn’t make this casserole for breakfast, but for brunch after church.  It’s a perfect after church meal, because it’s easy to throw together while you’re trying to rush everyone out of the house.  And the cook time is perfect to have it ready when you get back.

I used potatoes with onions and peppers in them to add plenty of flavor without adding a chopping step.  This one is really just “assembly only”.  Important when you’re trying not to be the last family to slip into the sanctuary.

Here’s what you’ll need:  

Ignore that bag of cheese in the photo.  I was using up what I had in the fridge, but ended up only needing the two small blocks of cheese.

The other great thing about this casserole is that you can start with the potatoes still frozen.  Just give the bag a whack or two, to loosen them up.

  1. I’ve wondered how these breakfast casseroles do in the slow cooker. I have several pinned but haven’t tried it. Looks good!

  2. Just out of curiosity, due to cook time, did you use a 4 qt or 6 qt crockpot? Thanks!

  3. I too have wondered about breakfast casseroles in the slow cooker. They seem so easy but wasn’t sure of what the texture of the eggs would be like. Your looks really good!

      I tried it on low for 8 hours and the texture of the eggs wasn’t like hers in the picture. My kids didn’t like it. I wonder if a shorter time would work better. I would like the trick. lol

  4. Did anyone else’s turn out very watery in the center?

    • Alli, I’m sorry yours turned out watery in the middle. I haven’t had that happen before. I’m not sure what would cause it, unless there was a lot of ice or moisture on the potatoes.

      • I’m not sure either, I think my crock pot may cook unevenly. I’m new to crock pot cooking and haven’t used it much, but this did happen before. Nevertheless, this was a delicious casserole. I scooped out what cooked around the side and stirred up what was fom the center and left it to finish cooking.

  5. I wanted to just let everyone know – my slow cooker is so old – most likely when they first appeared. I have made this at least 10 time and each time it is good. I have found using half pepper-jack cheese gives it a nice taste and no real spice to it. Also sometimes I will add some half and half if I don’t have enough eggs. I always turns out and I never have leftovers. I have done it also with turkey sausage too not the ham because some don’t like pork. Either I fry it up before or just use the precooked sausage links cut up.

  6. I need to be able to do this in large batches for a group of 100 at a camp this summer. I do not want to haul 10 crockpots with me but would like to cook it in the oven. How long do you think it would take to cook? At what temp?

    The hashbrowns should be completely thawed first.

  8. Made it exactly as stated in the recipe and it came out very good! It was a little dry, so I added some more cheese after it was done, and it was great! Easy, inexpensive recipe!

    • Beth Moore says:

      I’m glad you enjoyed it, Erin! And adding extra cheese is always a good solution for slightly dry anything!
