Mashed Potato Gratin

"I hear your family couldn't decide between mashed potatoes and potatoes au gratin? My mashed potato gratin combines both in one baking dish, so everyone at the table gets their favorite. The bottom layer is creamy sour cream mashed potatoes with green onions, while the top is made with thinly sliced potatoes and bubbly Gruyère cheese. This is THE potato side dish recipe for families with strong opinions about their potatoes. And let's face it, Thanksgiving dinner is not the time to start negotiating over side dishes. Two potato dishes in one. You get the creamy comfort of mashed potatoes and the golden, cheesy topping of a classic potato gratin without making two separate sides. "
