How To Make a Breakfast Casserole (Crock Pot Version)

  • HASH BROWNS: Shredded hash browns work best in this recipe. If you prefer more ‘potato’ in your casserole, you can certainly use diced hash brown potatoes or homestyle potatoes.
  • MEAT: I most often use sausage or ham. Bacon (or really any breakfast meat) will work perfectly in this recipe!
  • CHEESE & EGGS: I love the flavor sharp cheddar adds but any cheese works. Use whole eggs or even low fat egg substitute.
  • TOPPINGS: Feel free to add salsa or Tabasco and once you’re ready to serve, a nice dollop of sour cream and some chopped green onions!

Can You Freeze CrockPot Breakfast Casserole?

Like all casseroles, the best way to freeze them is to make sure they are fully cooled before they’re put in the freezer.
Once it is fully baked, chill overnight and then the next day, remove and either slice into portions and freeze individually or freeze in sections in a plastic bag. Just reheat in the microwave! Easy to make and easy to clean up!

  1. Hi there,
    Is 32 oz of hashbrowns for a single batch the correct amount? It seems like a lot so I wanted to double check. Making this for Christmas morning and I don’t want to screw it up!
    Thanks,
    Mega4 stars

  2. I made this recipe today for a Church breakfast we had. It turned out pretty good and everyone mentioned they liked it. I doubled the recipe and put it in a 7 Qt crockpot, a 6 qt would have been too small. When doubling the recipe it asked for 32 oz of hash browns, but I only used 24 ounces because I would not have had enough room in the crockpot. I cooked the casserole on low overnight from 12 AM to 7 AM; when I woke-up I noticed there was a lot of water at the top of the casserole. I uncovered it for another hour on low heat and it absorbed all the water. The Church breakfast was not until 10 AM so I cooked it on warm until 930 AM. I was worried by then it may be dried out, but it was not. The recipe does not specify the amount of salt to put in. I added 1 teaspoon salt and a 1/2 teaspoon pepper, and it still tasted somewhat bland. Next time I will add 1-1/2 teaspoon salt, I would also recommend sprinkling a little salt and pepper over each layer of hash browns. Since I doubled the recipe, I actually made three layers. I would definitely make this recipe again using the adjustments.4 stars

  3. I’m planning on making this recipe this weekend. Can I prepare it and refrigerate Friday morning and put on to cook late Friday night? Will the shredded hash browns be ok doing it that way?

  4. I have a 3qt crockpot. Does this recipe work with this size? If you use a 6qt crockpot do you think using half of the ingredients will work just as well? Thank you!

    1. The slow cooker should be between 1/2 and 3/4 full. If you try half of these ingredients in a smaller slow cooker and it is more than 3/4 full, I would suggest using the larger one. If halving the recipe or using a smaller slow cooker, the cook time might change. (Note: if you put the dry ingredients without the egg in the slow cooker and decide it’s too small, you can transfer them to the larger slow cooker, it’s ok if they’re mixed up instead of layered).

  5. Thank you for this recipe! We always want to invite friends over after church, and this is the perfect brunch dish to cook while we’re gone so it’s ready to go! I love that I can make it ahead of time and serve with fruit-voila! We used ham and it turned out great. The leftovers were also delicious! It easily fed 4 adults and 6 kids.5 stars

  6. I made the recipe exactly how the instructions say.(cooking on low for 8 hours) Overall- the flavor profile is good- however, the hash browns don’t seem to have held up.. any suggestions ?

    1. You will want to make sure the hashbrowns are being added to the casserole frozen. If they are defrosted they will cook faster and could end up falling apart. Hope that helps, Jenna!

  7. I made this exactly how it says and did it on high for 3 hours. At 2.5 hours the center was still all liquid so I mixed it all over in hopes to get it all to cook better. Where did I go wrong? Is it better cooking it on low?

    1. Hi Daria, I am not sure what went wrong. It should have fully cooked through. If you prepare it ahead of time and the mixture is very cold (from the fridge) it can take extra time to cook.

      You can test your slow cooker following this guide to see if your slow cooker is not getting as hot as normal.

    2. I’m cooking it now and it’s been on high, cooking for over 3 hours. Very liquidy in the middle. I’ve been cooking for over 20 years and followed the recipe exactly too. I can assure you it is NOT the heat from my crockpot, my crockpot works just fine, it IS the recipe itself So look, paid money for ingredients just to have it turn out like soup.

      1. So sorry this recipe didn’t turn out for you, Chrissy! I am not sure what went wrong, we have had great success with this recipe.

      2. IF you try this, or another recipe like it, again, put a paper towel under the lid to catch the condensation. Esp important in an eggy recipe like this to stop the condensation from the lid falling onto your casserole.

  8. If you don’t have a crockpot or would like to make it the oven, what do you think temperature and time would be?

    1. While we haven’t made this recipe in the oven, we do have a hashbrown breakfast casserole recipe for the oven. You could follow the steps there. It would likely take a little longer, maybe about 15 more minutes, because this recipe is a bit bigger. Hope that helps!
