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!

This slow cooker breakfast casserole recipe will take about 7-8 hours on LOW and 2 1/2 – 3 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 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. 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

  2. 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!

  3. 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.

  4. 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!
