Ingredients in Slow Cooker Breakfast Casserole
- HASH BROWNS: Shredded or diced hash browns work 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 substitutes.
- 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!
How To Make Crock Pot Breakfast Casserole
- Cook sausage or bacon if using, or dice ham per the recipe below.
- If desired, soften the onion in bacon fat or a bit of oil.
- Layer hashbrowns, meat, peppers, onions, and cheese in a slow cooker.
- Whisk eggs, milk, and seasonings and pour over the hashbrown mixture.
- Cover and cook per the recipe below.
How Long to Cook a Breakfast Casserole
This slow cooker breakfast casserole recipe will take about 7-8 hours on LOW and 3-4 hours on HIGH in a 6QT slow cooker. If you’re working with a smaller slow cooker or doubling the recipe, the cooking time may need to be adjusted slightly to compensate.
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 it overnight and then the next day, remove and either slice it into portions and freeze it individually or freeze it in sections in a plastic bag. Just reheat it in the microwave! Easy to make and easy to clean up!

My reply is that I have been searching for a new brunch recipe and looking at the ingredients and easy way to make this I have found it. Cannot wait to try this.
I am looking to triple the recipe and use 2 crockpots. Does the time differ?
I haven’t tried doubling or tripling this so I can’t say for sure, Sam. If cooking on low it make take an extra 1-2 hours but I have not tried it. If you try it I would love to hear how it turns out!
Could I prepare this ahead , refrigerate and just turn it on the slow cooker before bed?
Hi Laurie, I would have everything prepped and then just pour the egg mixture over top when you get up in the morning. I hope that helps!
If I prepared this ahead and refrigerate and just turn it on the slow cooker before bed? The next day pouring eggs on top, how long would it take for the egg to cook to completion?
Planning to cook this crockpot casserole for Nurse’s Week.
Thank you, Janie B.
If cooking on low overnight you can just prepare the entire casserole before bed (including the eggs in step 4). If you are wanting to prep the ingredients and then turn it on in the morning you can have everything prepped in the crockpot up to Step 3. Then in the morning you can add the eggs and turn on the crockpot to cook on low for 7-8 hours or high for 3-4 hours. I hope that helps!
My family loves this so much! I add mushrooms as two layers. And we do salsa after it cools bc we all like different flavored salsas. So yummy and easy. thank you
This is really yummy and great for a make ahead meal. We served it after my son’s baptism. 4 hours on high worked for us. I didn’t worry about cutting up onions and peppers but instead used O’Brien hashbrowns. So easy!
This turned out delicious! I made it with a pound of sausage and half pound of ham. After 8 hours on low I spooned off about 4 tablespoons of oil probably bc I used so much meat and then turned it to low. Was perfect for Christmas breakfast. I also made your crockpot Mac and cheese and it got rave reviews at a Christmas party we went to. Thank you so much!
This is my go to for Christmas breakfast. I set it for overnight and eat it in the morning and then have more breakfasts for days after I usually use sausage. I’m a dunderhead sometimes so its on high for 6 or so hours but it always turns out good.
Have you ever made this in the oven? Just thinking the potatoes would get crispy if baked in the oven in a casserole dish. I know that defeats the purpose of an overnight breakfast ready and waiting for you in the morning….
Yes, this Hashbrown Breakfast Casserole is similar. It can be made ahead and is baked in the oven.
We found this rather dry. Way too many potatoes. I’d make it again, but would use less hash browns.
Thanks for trying our recipe, Lori! I would love to hear how it turns out for you.
Delicious! Everyone raved about it. I used diced potatoes and two different meats… 1/2 pound of bacon + 1 pound of sausage. The potatoes were super tender, but I think I might like hash browns better. I cooked it for 7 1/2 hours. Everyone slept in, so it was on “warm” setting for three more hours, and it was definitely cooked through. I wanted to serve it on a platter vs. out of the slow cooker. But I had to cut it into huge pieces to remove it. The presentation wasn’t very pretty but the taste was great. Any idea about removing it in one whole piece? Maybe line the cooker with overhanging parchment paper? Thanks for the recipe and will make it again!
You could try parchment paper or using a crockpot liner so you can lift it out.
Do you think this recipe turns out better cooking it on LOW or HIGH?
I have made it both ways with great results. It just depends on how much time you have to wait for it to cook.
I made this for Father’s Day brunch yesterday. It was great. I used pork sausage as the meat. It took 3.5 hours on high. It was delicious. It made great leftovers too. I’m not usually a fan of breakfast casserole but this was great.
This CrockPot Breakfast Casserole sounds and looks so delicious!! I do have a question though. Would it be alright to add the suggested salsa and the small diced cooked onion to the crumbled cooked sausage and then layer as suggested?
I have not tried but that sounds delicious. I would love to hear how it turns out!
what would be a good substitute for the peppers? some of our family won’t eat them. it seems that the peppers would add moisture to the recipe. thanks
You can leave them out if you’d like.
