Adapted from Real Simple magazine. If you choose to use Russet potatoes (which the recipe originally called for), they will need to be peeled. I usually decrease the amount a little and bake this in a pie plate. Since it ends up being stacked 2 partial rows high, I can skip the first 25 minute bake and just bake uncovered for 1 hour and about 15 minutes. The deeper the potatoes are stacked, the longer it will take to bake. Also, I tend to substitute half & half for heavy cream and that works just fine in this recipe.
