Such an Easy Overnight Recipe

This casserole is perfect if you have overnight guests that need feeding in the morning. It takes around 8 to 9 hours to cook the casserole in the slow cooker, so pop everything in just before you go to bed and you will wake up to a ready to serve hot breakfast.

Variations

I love this recipe, as it's so easy to adapt it to different tastes and diets.

You can use 1 pound of breakfast sausage in place of the bacon. Brown and crumble the breakfast sausage then drain and continue with the recipe as written.
It's so easy to make this Crockpot breakfast casserole vegetarian. You can simply omit the bacon, or you could substitute it for vegetarian bacon or sausage.
If you prefer, you can use non-dairy milk or half-and-half. I like Ripple's Half and Half.

How Long Does It Keep?

This is such a great make-ahead breakfast, not only can you cook it the night before serving, but it also stores well too. Transfer the cooked casserole to an airtight container and it will keep well in the fridge for about three to four days and then you can reheat it in the oven.

Top Tips For Making

When sprinkling on the cheese, leave a slight border from the sides of the crockpot. This will prevent as much burning of the edges as possible
There will be SOME burning on the edges but it won't affect the rest. just leave a small border when cutting into the casserole to serve
You must spray the crockpot first. this dish cooks for quite a long time and will burn or stick otherwise
