1. Slice potatoes 1/8" thick. Put slices in a pot with cream, garlic and goat cheese. Season with salt and pepper. Place over medium heat. Bring to a simmer and cook 12-15 minutes until potatoes are very tender when poked with the tip of a knife. Transfer to a buttered 8" square baking dish. Bake at 375 for 20-25 min until golden brown.
