Getting this casserole going the night before doesn’t take too many steps.  The only things we need to prep is dicing up the onion and bell peppers and cooking the sausage.  We want to have the sausage cooked before adding it to the slow cooker because we want to get rid of the grease.  Not a fan of sausage?  Swap it out for bacon.  Just follow the same steps of cooking it before adding it to the slow cooker.

I use diced hash browns when I make this casserole.  But you can absolutely make it with shredded hash browns, like this Hashbrown Breakfast Casserole, if you prefer.  You can dice up your own potatoes, or if you’re like me and at the end of the evening you just want to head to bed for those precious few hours of sleep, just use the frozen version.  We can toss them into the slow cooker still frozen and they cook up perfectly.

We top it all with cheese and pour the egg mixture on top of it all.  You will wake up to the most amazing smell and breakfast already made!  If you’re planning a later brunch or are wanting this for dinner (because let’s face it…sometimes breakfast for dinner is a must) this can be made in 4 hours on a high setting also.

  1. This was delicious! I have two questions: If someone can’t eat dairy, do you think goat cheese or something else would work. ( I know, nothing tastes better than cheese! ). Secondly, if unable to stay up to midnight, and don’t have a timer option, do you think if I refrigerated this for a few hour and the put it on low at about 10 pm that it would overlook by 8am?

  4. We made this for a fundraiser dish at work last weekend and ended up mostly eating it on bread as a grilled cheese sandwich heated on the George Forman press. It was so good even the next day leftover!

    1. You can! Personally, my slow cooker is still hot and cooks on the warm setting though, and so it singed the edges of my casserole one time when I did this. Just beware!

      1. Shredded hash browns might cook up too soft. I prefer the diced potato to keep some shape. But I wouldn’t add any water if you do decide to use shredded potatoes instead.
