Other smoked cheeses (Mozzarella, Swiss) also work well in this recipe.
Serves 4
Heat oven to 350. Blanch potato slices in boiling water for 5 minutes. Drain and rinse with cold water. Spray a two-quart casserole with oil. Make a layer of 1/2 of the potatoes. Top with the cheese, onion, and flour. Top with the rest of the potatoes. Season. Slightly heat the milk and pour over the casserole. Cover and bake for 50 minutes. Uncover and bake for 20 minutes longer (or until lightly brown). Serve warm.
