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.

Made this for my family for breakfast. I followed the recipe except I used all eggs instead of eggs and egg substitute. I also didn't add the dijon mustard(personal preference). We enjoyed this as it was something different for breakfast. It was also nice that I made it up the night before and just had to pull and pop in the oven in the morning.
