Slow Cooker Breakfast Casserole
on Jan 17, 2020, Updated Jan 30, 2024
Slow cooker breakfast casserole is the easiest way to make a delicious and filling breakfast. Make it the night before for a full breakfast the next morning or take it to your next potluck brunch.
This slow cooker breakfast casserole is full of protein that will keep you going all morning. The base of eggs is healthy, and you can add any breakfast meat such as sausage or bacon. You can even keep it vegetarian and skip the meat.
Customize it with the veggies you most enjoy and dump in frozen hash browns. These shortcuts make it easy to feed a crowd, eat a healthy breakfast without a lot of effort or enjoy breakfast for dinner. With a seven quart slow cooker, your options are endless for feeding a crowd.
How do you cook breakfast meat in the slow cooker breakfast casserole?
The method for cooking your meat for this crock pot breakfast casserole depends on the kind of meat you want to use.
I used bacon in the original recipe. I cooked in it a skillet before putting it in the crock pot. Bacon will not get crispy in the slow cooker so it’s best to cook that beforehand. You can do it in the skillet or oven. You could also eliminate this step and use precooked bacon or leftovers from another meal.
You could also use sausage in this recipe just as easily. You can put raw sausage in the crock pot, but I still recommend that you cook it fully in a skillet first. As long as the sausage reaches an internal temperature of 165F, it will be safe to eat. This will require cooking it for four hours at high or eight hours at low.
Other breakfast meats you could try are:
- Turkey bacon
- Turkey sausage
- Ham
- Lox
What veggies can you put in this crock pot breakfast casserole?
Besides the meat and eggs, you can put lots of fresh veggies in this slow cooker breakfast casserole.
I always use onions, green peppers and red peppers. Try some of these veggies too:
- Mushrooms
- Carrots
- Peas
- Zucchini
- Spinach
- Broccoli
- Roasted red peppers
- Tomatoes
Ingredients for Slow Cooker Breakfast Casserole
- Frozen Hash Brown Potatoes (Note: I actually use shredded Has Browns, my image shows cubed)
- Eggs
- Milk
- Cheese
- Bacon
- Peppers
- Onions
How to Make Slow Cooker Breakfast Casserole
First, grab your favorite large crock pot. I used my 7 quarts cast iron style. Then, add half of the bag of hash brown potatoes.
Next, you will need to add half of the bacon on top of the frozen potatoes.
Now, add half of the green peppers and half of the red peppers. Also, add half the onions.
Then, add half of the shredded cheese. Tip: use a brick of cheese and shred yourself, the results are much better than with store-bought pre-shredded cheese.
For the next step, you will repeat adding another set of layers of potatoes, meat, veggies, and cheese. Then, in a small bowl whisk together the eggs and milk. Now, pour the egg mixture on top of the layered casserole ingredients.
Finally, add a double thick paper towel to the top of the crock and place the lid to hold in place. Cook the breakfast casserole on warm for 8 hours or on low for 4 hours.
Note: All slow cookers cook differently. I have made this casserole MANY of times in both of my large slow cookers. It turns out wonderful each and every time.
Should I thaw frozen hash browns before putting in a crock pot breakfast casserole?
A breakfast casserole with frozen hash browns is easy to prepare.
If you preferred to use fresh potatoes, you can dice or shred them. You could also use sweet potatoes for even more healthy nutrients.
But the quickest way to make this casserole is using frozen hash browns. It is perfectly OK to dump the hash brown into the crock pot from frozen.
If you make this and find it’s a little runny, you may want to thaw out your hash browns next time. Frozen food keeps a lot more moisture that fresh. Just leave the hash browns in the refrigerator for a few hours before you plan to use them. Dry them on a paper towel before adding them to the casserole.
How do you know when a breakfast casserole recipe is done?
It can be difficult to tell when a breakfast casserole in the crock pot is completely cooked and ready to eat.
A knife slid into the middle of the casserole should come out clean. But if you have trouble telling the difference between uncooked egg and melted cheese, use a kitchen thermometer. Eggs should be 160F when they are cooked.
How do you keep scrambled eggs warm in a crock pot?
Not only is this a great recipe for breakfast or dinner, it can be taken to a potluck meal or family brunch.
Because we are making it in the crock pot, it can be kept warm for hours. Just leave the entire meal in the crock pot and set it to low. I do recommend you eat it within four to five hours if you keep the crock pot on. Eventually, it will dry out the eggs and they will start to become rubbery.
But that leaves you plenty of time to offer and protein packed hot meal to anyone who is visiting, even if they come in shifts!
You can also make this meal in the evening and have it ready for breakfast the next morning.
Other great make-ahead breakfasts are:
- Apple Overnight French Toast Casserole
- Cracker Barrel Copycat Hash Brown Casserole
- Biscuits and Gravy Casserole
Can you reheat crock pot breakfast casserole?
This works great as leftovers as well. If you want, make a huge batch and eat it for a few days for breakfast.
To reheat, pop a single piece into the microwave for a minute. To reheat larger potions, you can put it in the oven at 350F until warm all the way through.
Can you freeze hash brown breakfast casserole?
This recipe can be used for meal prep as well. You can freeze this either before or after you bake it.
If you want to freeze it before baking, mix together all of your ingredients in a glass container or a freezer safe foil dish. Cover it tightly and freeze.
You can bake this first or just freeze the leftovers. If you are meal prepping and plan to freeze the entire casserole, under cook it just a little. That way it won’t dry out while you are reheating it.
Allow the casserole to cool completely and then cover tightly.
Hash brown casseroles will last in the freezer for three months. Thaw it in the refrigerator before reheating. You can either dump it back into the crock pot or reheat in the oven until set and golden brown.
Another option for meal prep is to put everything in your crock and leave it in the refrigerator until you are ready to cook it. An uncooked breakfast casserole will last in the refrigerator for three to four days.
The slow cooker is great for making breakfast with less effort. If you have an Instant Pot and need a great breakfast casserole recipe made in a pressure cooker hop on over to a Typical Mom’s Instant Pot Breakfast Casserole recipe.

I’m curious when and why was the step of putting paper towels on top then adding the lid…added? Has anyone ever used paper towels? Did you have any problems with the cheese sticking to the paper towels? After years of making this and changing the ingredients so many different ways we still love it…I had to go up to a little larger crockpot because of all the extras.
Tear the paper towels long enough to go over the top of the crockpot then put the lid on. Toweling helps absorb the moisture & keeps the condensation from getting in the eggs. The instructions are incorrect- should cook on high 3-4 hrs or low 8 hrs. I have made this several times over the past 35 years & it has always been a great hit.
Thank you for that information!
Thank you, I’ve also been making this for yrs and never understood the paper towels until you explained it. I’ve never used them but now that mushrooms are always added to mine, I think they would definitely help with the extra moisture they create. Thanks again for the explanation.
Do u need to spray nonstick cooking spray in crockpot ?
I have tried a similar recipe in the oven but never in a crock pot. I’m sure it is delicious either way and a great way to cook it while you are away from the house. I have pinned it to try out. Thanks for sharing at #HomeMattersParty
This sounds like the perfect recipe to bring in for the teacher appreciation potluck breakfast they have every year at my children’s school. This breakfast casserole sounds delish and I like that it will stay warm in the slow cooker!
I was skeptical with this as I wondered how cooking it on high for 8 hours would work, but it does!! I accidentally came across this recipe this fall and made it in my large crockpot for a tailgate the next day and everyone loved it! I actually used sausage instead of bacon, but that’s just personal preference but I’m making it again for a holiday brunch this weekend and will mix both. This is a great and easy recipe!!
Can I use a crock pot for this . I don’t have a slow cooker. Or can I bake it in the oven in the morning.
So glad that I read the reviews. I haven’t tried the recipe yet, but will definitely cook on low for 8 hours.
Warm does not cook this recipe. Do not cook it on warm, use a higher setting or you’ll have raw egg soup after eight hours.
So I attempted to make this Christmas morning for the whole family, my in laws were here and was trying to make a good impression. The eggs did not set, did not want to risk food poisoning so threw the whole thing out and we all had cereal. Was pretty disappointed considering how much food was wasted, and it was Christmas morning. But I have hope, this looks really delicious. So I am attempting it AGAIN tonight! But putting the slow cooker on LOW not Warm. Here’s hoping it turns out!!
I’ve made this several times and have one in a crockpot now. The 1st time I made it, it was not only for for my husband to take to a work place breakfast during the holidays of 2014. It was also untested, untasted and…for the police dept. I was not only asked for the recipe I was also asked to send 2 for every breakfast they have!! It’s such a good way to start off the day. On the last day of his work week or over a long wkend, I’ll fix a big meal with plenty of leftovers, make one of these & then no more cooking for me!! I also love that there’s so many different ways to change it up. Definitely a keeper!!
I made this following recipe but adding 1 cup extra milk and a layer of thinly sliced bread, and cooked it on LOW, not warm, for 8 hours in my large RIVAL crock pot, and it was perfectly cooked.
I made this for Christmas morning, and it was a huge hit. Being a Texan, I added more of almost everything, but kept the amount of potatoes the same. . .a whole onion instead of a half, about 3/4 of each kind of pepper, 3 extra eggs, extra cheese – a mix of cheddar and pepper-jack, and about a half-cup more milk. I also divided the items into thirds and made the casserole three layers instead of two.. I baked it overnight on medium (about 8 hours) and it cooked through perfectly! I put flour tortillas and salsa out on the table for those who wanted to make breakfast tacos out of their serving of casserole. Next time, I’ll try adding some green chiles and will report back to let you know how it turned out. Thanks for this fantastic idea! It’s definitely going to become a Christmas morning tradition for us :)
