Cheesy mashed potatoes

This Christmas I got the urge to try a bunch of new and different recipes. I was watching the food network (as always) and Giada De Laurentis was making this recipe for mashed potatoes. They sounded so yummy I knew I had to try them. I know it not a great idea to try new recipes for the first time on a holiday, but when else am I going to make such a decadent dish?
Well I made it, and EVERYONE loved them! My sister told me that my niece never eats mashed potatoes....well she ate her serving and asked for more! I got so many compliments. This may become a family tradition!
