Quickly thaw the potatoes by microwaving them in a microwavable bowl uncovered on High for 3 to 5 minutes, stirring once.
This potato casserole goes well with egg dishes, ham and other breakfast main dishes. Round out the brunch with sliced fresh winter fruits and a coffee cake.
Assemble all of the ingredients in the baking dish, and cover and refrigerate up to 12 hours ahead. You don’t need to thaw the potatoes because they’ll thaw while in the fridge.
