Simple Scalloped Potatoes
Preheat oven to 350 degrees. Butter a 2-quart shallow baking dish and rub with garlic. Layer potatoes in dish, overlapping slightly. In a small bowl, combine milk, cream, salt, and pepper. Pour cream mixture over potatoes and dot with butter; cover with foil.Advertisement
Place dish on a rimmed baking sheet and bake on top rack until potatoes are tender when pierced with a knife, about 1 hour. Uncover and bake until top is golden in spots, 30 to 40 minutes. Let rest 20 minutes before serving.
Tips: Peeling is easier and faster with large potatoes. Don't rinse the starch off; it will help to thicken the sauce. To prepare ahead, assemble the scalloped potatoes up to 6 hours in advance and refrigerate, covered with foil. Allow potatoes to come to room temperature before baking.
