  1. Cut bacon into small pieces, cook and drain (You could use precooked bacon to speed up the process).
  2. In the bottom of a slow cooker, layer: half of the hash browns and half of the following: onions, bacon, green and red peppers and cheese. Repeat layers with the remaining ingredients ending with cheese.
  3. In a medium sized bowl beat eggs and milk together. Pour egg mixture over the casserole and top with salt and pepper to taste.
  4. Cook on Low for 6-8 hours (or high for 2 1/2 – 3 hours).

    1. I haven’t tried halving this recipe so I can’t say for sure. I do think it would need about 3/4 of the cooking time. You’ll want to make sure the eggs are cooked through. Let us know how it goes.

  1. Am planning on making the Slow-Cooker Breakfast Casserole for a brunch tomorrow. Just wondering about the hash browns. Should they be thawed before putting them in the slow cooker.

    Thank you.

  2. Contemplating somewhat heavily on trying this little casserole recipe out for Christmas morning; I have one question though: Where do you put the diced and cooked bacon, on top of the casserole when done, or the interior of the casserole the bacon once it’s well-cooked, or the bottom of the thing? The recipe doesn’t specify where you put it at all (at least for me). Other than that, it looks so dang good! Merry Christmas, Holly!

  3. This looks delicious can’t wait to try it. Out of curiosity, have you ever tried adding Spinach to this recipe? If so, how did it go? 

  4. Can you half this recipe? It’s just my girlfriend and myself. I know we won’t be able to finish it all and don’t want to waste it. If it’s in half, would the time be different?

    1. Yes, you can half this recipe (and I have many times). I cook it in an 8×8 dish for about 40 minutes (ensure a knife comes out clean). If you do end up with leftovers, it reheats beautifully.

  5. I am disappointed! Only thing different is I added mushrooms and this turned out awfully dry and bland! I’m glad I woke up early and checked on it because it would have been completely inedible by 6am after being on low for 8hrs! It is dry and crispy! Good thing my hubby will still eat it, he doesn’t like to waste food!

    1. Oh no Kristy, I’m so sorry this didn’t work out for you. How disappointing!! My slow cooker cooks this recipe perfectly with very slightly crispy edges. What size of slow cooker did you use?

  6. Will the eggs turn rubbery if you cook it for 8 hours on low then let it sit on warm until everyone is up and ready to eat breakfast?

  7. I tried the recipe on high for 4 hours and it was delicious. Thank you for the recipe and idea. My family loved it and my husband woke up this morning on father’s day to this delicious breakfast. And breakfast is his favorite meal so he was in heaven. He said this is my breakfast lunch and dinner!!!

    Thank you again.

  8. This sounds great, I plan to make this for friends as a thank you for helping my fiance and I stuff our wedding invitations this coming Sat morning.

    Do you know if shredded russet potatoes would work, rather than frozen?

    Thank you!

  9. I am cooking for one – How many days will this last? If I make it on Sunday night can I eat it for breakfast throughout the week?

    1. I haven’t kept it longer than 3 days. If you would like to keep it longer you may try freezing it. Please let us know how it works out for you.

  10. What is the best size of crockpot to use and how many does it feed?

    My brother made it for a brunch for a bunch of his friends.


  11. Do you think this is something that could be made on a Thursday night and keep it in the fridge until Saturday morning? If I’d make the dish ahead of time then add the eggs and milk before I heat it up

  12. this looks so good! We do Thanksgiving breakfast at our house. This would be a great thing to make and free up some space on the stove and in the oven!
