Gratin of Sweet Potatoes and Bourbon Recipe

Gratin of Sweet Potatoes and Bourbon Recipe

  • 3 pounds dark orange sweet potatoes
  • 4 tablespoons (1/2 stick) butter, plus butter for the baking dish
  • Salt
  • 1 cup heavy (whipping) cream
  • 1 tablespoon bourbon
  • Freshly grated nutmeg
  1. Preheat the oven to 350°F.
  2. Roast the potatoes on a baking sheet in the oven until they are easily pierced with a knife, about 45 minutes. Remove them from the oven and let cool. (The potatoes can be roasted up to 2 days in advance and refrigerated.) Leave the oven on.
  3. Butter a gratin dish or baking dish.
  4. Peel the potatoes and cut them into 1/4-inch-thick slices. Arrange the slices in a single layer, overlapping them. Season to taste with salt.
  5. In a small saucepan over medium heat, reduce the cream by one-third. Add the bourbon and whisk well.
  6. Pour the cream over the potatoes. Dust the potatoes very lightly with nutmeg and dot with the butter. Bake until browned and puffy, about 30 minutes. Serve hot.
