Hearty Swiss Potato Casserole
All-purpose flour can be substituted for the whole wheat if desired.
Top with bread or cracker crumbs after the first 20 minutes of baking if you like.
Baking time will mostly depend on how thinly you sliced your potatoes. To check doneness, stick one with a fork; if it pierces the potato with no resistance, it's done. (I like my potatoes with a little bite, so I cook mine less.)
