This recipe for scalloped potatoes is a basic combination of red-skinned potatoes, a homemade sauce, and sliced green onions. If you aren't a fan of green onions, add finely chopped sweet or yellow onions or leave them out entirely. A dash of nutmeg and a small amount or dried mustard give the sauce excellent flavor. Use freshly grated nutmeg if you have it. To speed up the baking process, boil the sliced potatoes for about 3 to 5 minutes, or just until the edges are somewhat tender, before mixing with the sauce and baking. The potatoes will take far less time in the oven.
