Christmas Dinner always has a cheesy potato dish. I think it is just customary. Or at least it is in our house. I don't think I have ever turned down a potato dish even when dieting. I just cant resist. At Christmas we usually have a standing roast and cheesy potatoes just go hand and hand with red meat.
This potato dish is as easy as it comes for Augratins. You dont need to slice it all up pretty. It's a dump it and bake it dish. I dont even really measure. I am giving you measurements but feel free to wing it. With all you have going on Christmas day, this is perfect. No fuss. It can even bake along side something else.
