  • 3lb of potatoes, peeled and sliced (7 medium)

When you get to the top layer, arrange the potatoes neatly, starting around the edge of the dish and slightly over lapping, ending up in the center for a gorgeous presentation. Add a thin layer of shredded cheddar to top, sprinkle with a dusting of flour.
Bake, covered for 30 minutes.
Bake uncovered for one hour to one hour and 15 minutes, until soft and tender all the way through when tested with a knife and lightly browned on top. Let stand several minutes before serving.
Makes 6 one cup servings, or 12 smaller 1/2 cup servings.
