Our standard potato recipe every Thanks Giving and Christmas.
use enough potatoes to fit into a 9" by 12" by 2" baking dish. peeled and sliced 1/l8 to 1/4"
layer potatoes, salt and pepper, then sauce to cover the potatoes, cover with foil, poke holes for steam to escape.
Bake for 1 and 1/2 to 2 hours at 375 or till tender.
Sauce - 2 large packs of cream cheese, stick of 'real" butter, NO whipped or watery stuff, around 3 cups milk.
Heat in a sauce pan until melted. Do not fill baking dish to the top, Milk will boil over. put another piece of foil on the bottom of your oven just in case. I save any left over sauce in case the potatoes get too dry to pour over the potatoes later.
Everyone loves them.
