Total time: 1 hour, 20 minutes
Servings: 10 to 12
2 tablespoons softened unsalted butter
4 pounds sweet potatoes
Salt, freshly ground black pepper
1 1/2 cups heavy cream
1 tablespoon chopped fresh thyme
1. Generously butter a 2-quart gratin dish and set aside. Heat the oven to 425 degrees.
2. Peel the sweet potatoes. Using a mandoline or sharp knife, cut into slices one-fourth-inch thick. Arrange the slices in overlapping layers in the dish, seasoning each layer generously with salt and pepper.
3. Combine the cream and thyme in a small bowl and mix well. Pour evenly over the potatoes, coating all exposed surfaces. Cover the dish tightly with foil and bake 45 minutes.
4. Remove the foil; continue baking until the sweet potatoes are soft and caramelized, 15 to 20 minutes longer.
