Overnight Cheesy Breakfast Casserole

This amazingly simple casserole recipe starts with a scrumptious layer of left over buttery biscuits, it’s filled with my favorite breakfast components and ends with a generous amount of ooey gooey cheese. It is a complete breakfast. Just add coffee or orange juice.



Breakfast casseroles have been a long time favorite in our house.  I love to make it the night before and just pop it in the oven that morning.  These come in extra handy on special occasion days; like Easter, Christmas, Mothers/Fathers Day.  Pretty much every morning that I don’t want to spend a lot of time in the morning preparing food, a breakfast casserole comes in handy.

This casserole combined my favorite flavors and left over biscuits.  You know in a bread loving family there are bound to be biscuits laying around.  If you don’t have biscuits, feel free to substitute Italian bread.

Layers of buttery biscuits, sausage, ham, red peppers and cheese (cheese and more cheese) come together with fluffy eggs to create the best ever overnight cheesy casserole.  Perfect for everyday and every holiday.  It doesn’t get much better than that!
