What temp and how long for scalloped potatoes?

Bake scalloped potatoes at 350°F (175°C) for about 1 to 1.5 hours. The potatoes should be tender and the top golden brown. Cover with foil for the first half of the baking time to prevent excessive browning, then remove the foil for the last 30 minutes. Always check for doneness by inserting a fork into the potatoes; they should be soft and creamy.
