20 minutes

1 hour, 25 minutes



  • 1 3/4 cups heavy cream
  • 6 tbsp. butter, cut into 1-inch pieces
  • 1 sprig fresh thyme, 1 bay leaf, 2 sprigs fresh parsley, and 1 sprig fresh sage—tied together with kitchen twine
  • 3 lb. sweet potatoes (preferably a mix of yellow and orange), peeled
  • 2 cups grated Gruyère


1. Preheat the oven to 400°. In a saucepan, bring the cream, butter, and herbs to a simmer. Remove from heat. Using a mandoline or  a food processor with the slicing disk, thinly slice the potatoes. In a large bowl, toss the potatoes, 2 tsp. salt, and 1 tsp. pepper. Toss in 1 cup cheese. Spread in a greased 3-qt. baking dish.

2. Discard the herbs in the cream; pour over the potatoes. Press down on the potatoes to partially cover with the cream. Sprinkle with the remaining 1 cup cheese. Tent with foil and bake for 30 minutes. Uncover; bake until the potatoes are tender and the top is browned in spots, 20 to 30 minutes. Let rest for 15 minutes before serving.
