Other smoked cheeses (Mozzarella, Swiss) also work well
in this recipe.
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. Salt and pepper to taste.
