Scalloped Potatoes (Kentucky Style)

The dish can be assembled up to 4 hours ahead through step 4, covered tightly with plastic wrap, and refrigerated. Add 10-15 minutes to the baking time if starting from cold. Pour the hot milk over just before baking for best results.

Store leftovers covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave at 50% power, or reheat the entire dish covered with foil in a 325°F oven for 20-25 minutes until warmed through. The sauce may thicken upon standing; thin with a splash of milk if desired.
