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 Long to Cook a Breakfast Casserole

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!

  • 1 bag frozen hash brown potatoes 32 ounces
  • 1 pound bacon, sausage, or ham cooked & cumbled or diced
  • 2 cups sharp cheddar cheese shredded, about 8 oz
  • 2 green onions sliced
  • 1 small finely diced white onion about ½ cup
  • 1 red bell pepper diced
  • 1 green bell pepper diced
  • 12 eggs
  • 1 cup milk
  • 1 ½ teaspoons dry mustard powder
  • 1 teaspoon salt
  • 1 teaspoon garlic powder
  • ½ teaspoon black pepper


  • If using bacon or sausage, cook and crumble. Drain fat leaving 1 tablespoon in the pan.
  • If desired, soften the onion in the fat. This is optional but will soften the flavor of the onion.
  • Grease a 6qt slow cooker. Place half the hash browns, meat, onions, peppers, and cheese in the slow cooker. Repeat layers ending with cheese, do not stir.
  • Whisk eggs, milk, and seasonings in a medium bowl. Pour the egg mixture over the ingredients in the slow cooker.
  • Cook on low for 7 to 8 hours or high for 3-4 hours. Once cooked, uncover and let the casserole rest for 15 minutes.



Hashbrowns: You can use shredded or diced hashbrowns in this recipe. Diced hashbrowns have more of a ‘potato’ texture. Use hash browns from frozen, thawed hash browns will cook faster.
Onion: For a milder onion flavor, cook the onion in a bit of bacon fat or olive oil before adding the to the slow cooker.
Cooking Time: Cooking time can vary slightly based on your slow cooker. If the casserole is done cooking early, turn the slow cooker to warm and let it rest for up to 1 hour before serving. If using bacon or sausage, you may see a little bit of fat along the edges of the slow cooker, and there will be a little bit of liquid along the edges and perhaps on top. This is expected and most of the liquid will evaporate as the casserole rests.

  1. 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?5 stars

    1. If I double the recipe can I still use a 6 quart pot and if so how much longer do I need to cook it. What if I cooked it in the oven and then put into crock pot to keep warm?

  2. Planning to make this for Christmas morning. When layering, are the onions & peppers layered on their own, or mixed in with either the meat or potato? I’ve seen very similar recipes, but it says to mix it all before pouring the egg mixture over. I’m unsure which would be better. Anyone done it mixed v layered?

    1. Hi Karen, onions and peppers can be mixed with the meat before layering or they can be layered on their own. The important thing would be to not mix the layers before adding the egg mixture.

  3. Hi Holly! I have made this recipe many times and it is absolutely fabulous! Everyone loves it. Thank you so much for sharing it. I was wondering if I could get the crock pot ready tomorrow morning and then just refrigerate it and start the slow cooker tomorrow night before bed. Do you think that would work or it shouldn’t be in the fridge that long? Thanks so much!!5 stars

    1. The mixture will be fine in the fridge overnight.

      On the manufacturer’s site, Crockpot suggests that it is okay to go from fridge to the cooker however, but it is very important to note that starting to cook with cold stoneware and cold food will affect the ramp up time of the slow cooker. Always add sufficient time into the cook time to ensure food is safe and cooked through.

      As I haven’t tried it this way, I can’t say for sure how much extra time you’ll need but I would suspect at least an hour.

  4. I need to use up some buttermilk I have left over from making biscuits. Do you think I could use it in this recipe or would it be nasty?

  5. Thank you for this recipe. I modified it a little bit, but not too much. I used hot Turkey Italian sausage, a diced ham steak, and bacon. Didn’t use frozen potatoes but I used cubed red potatoes and yams (nice sweetness). Wasn’t sure of the amount but it filled up my 6.5 qt crockpot.

    The leftovers can be used to make breakfast burritos, or do a breakfast bowl. I had leftover Spanish rice, guacamole, and shredded lettuce. Top the egg mixture on top of it and voila, another meal.5 stars

  6. This was delicious. I’ve made it a couple times. One time I didn’t have frozen hash browns, so I just shredded potatoes, rinsed them, pat dry, and they worked perfectly. I also add a can of green chilis. I’m making it again tonight for dinner.

  7. This was SO delicious! I followed the recipe exactly and it was cooked after 3 hours on high. I will definitely be making this again!5 stars

  8. Hi there! If I were to do in a dutch oven, would I follow the standard conversion of 15 minutes per hour on low at 325F? If yes, that would put it to 1.5h to 2h cooking time. Would you agree?

    I am thinking of doing it this way because even on high to make for breakfast I’d have to get up in the wee hours.

    Your thoughts?

      1. I saw that recipe and it does look good but I’m keen to try this one as it’s layered! I will try with 1.5 hours and see how it turns out…will keep you posted!

      2. Hi Holly! I am sorry for my tardy reply but wanted to confirm that doing the casserole in a Dutch oven was amazing! I cooked mine in a 6.7 Quart Dutch oven (greased), cooked at 325F for 1.5 hours.

      3. I’m so glad you loved it, thank you for coming back and letting us know as it’s helpful for others!

  9. I’m wondering if the frozen hash browns need to be thawed before adding them to the slow cooker.

    1. I haven’t tried doubling this so I can’t say for sure Rebekah. 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!

    2. I’m going to try the doubling the recipe as well. how did yours come out? how long did you cook it, on high or low?

  10. I brought this to a company meeting. It filled the crock pot nearly full and I would say made more than 8 servings but I did add 2 more eggs and about 4 -6 oz more potatoes. I also used potatoes O’Brian because it already had the white onion and bell peppers but for more hearty bell pepper onion flavor I would add more. I had several people ask me for the recipe.4 stars

  11. Can I make this ahead of time and refrigerate until ready to cook? We won’t need it till 10am but don’t really want to wake up at 2am to put it all together, lol.

    1. Hi Jocelyn, you can have everything prepped and just pour the egg mixture over top when you get up in the morning.

  12. Made for Christmas morning. It took a bit of prep but included everything my family loves. The potato texture was crumbly and it was watery at the bottom. ☹️ Maybe cooked too long? It really smelled great but we ended up not eating it. I was so disappointed. Sad to see bowls uneaten. Any ideas? P.S. I do love your recipes.

    1. Oh no Kim, how disappointing; I’m sorry this didn’t work out for you. There will be a little bit of liquid at the bottom, but I find as it rests it tends to mostly absorb. As for the potatoes, I’m not sure what type you have used, but I have made this with both shredded and diced hashbrowns. The diced tend to hold their shape and give more of a potato texture while the shredded tend to meld a little bit more into the egg mixture.

  13. A fellow board member made this for our non profit staff Christmas brunch! It was a huge hit!! I am now making it for Christmas morning with my son and his family!! Thank you for sharing!5 stars

    1. I haven’t tried halving this recipe so I can’t say for sure. I do think it would need about ¾ of the cooking time. You’ll want to make sure the eggs are cooked through. Let us know how it goes.

  14. I make this every year for Christmas morning breakfast. Family LOVES it! Make it exactly as written. Wouldn’t change a thing. Thank you!
