Overnight Egg Casserole

READY IN: 1hr 15mins
Recipe by PaulaG

This recipe is adapted from a Taste of Home recipe. Loved the use of the shredded hash browns instead of bread in the dish. Makes serving breakfast for a crowd a true delight. The O'brien style potatoes have onions and bell peppers added to them.

This is a good casserole! I mixed it up the night before in about 10 minutes and then baked the next morning, what could be easier?! Next time I think I might brown the hashbrowns a little first. DH also requested there me more cheese added. Made for 8th Annual Photo Swap February 2010.
