Total Time:
1 hrs 20 mins
10 servings


  • 1 (14.1-oz.) package refrigerated piecrusts

  • 1 tablespoon chopped fresh rosemary

  • 1/4 teaspoon freshly ground pepper

  • 2 cups (8 oz.) shredded Gruyère cheese, divided

  • 1 1/2 pounds Yukon gold potatoes

  • 1 1/2 pounds sweet potatoes

  • 1 teaspoon kosher salt

  • 2/3 cup heavy cream

  • 1 garlic clove, minced

  • Garnish: fresh rosemary sprigs


  1. Preheat oven to 450°. Unroll piecrusts on a lightly floured surface. Sprinkle rosemary, pepper, and 1/2 cup cheese over 1 piecrust; top with remaining piecrust. Roll into a 13-inch circle. Press on bottom and up sides of a 9-inch springform pan; fold edges under. Chill.

  2. Meanwhile, peel and thinly slice Yukon gold and sweet potatoes.

  3. Layer one-third each of Yukon gold potatoes, sweet potatoes, and salt in prepared crust. Sprinkle with 1/4 cup cheese. Repeat layers twice, pressing layers down slightly to fit.

  4. Microwave cream and garlic in a 1-cup microwave-safe measuring cup at HIGH 45 seconds; pour over potato layers in pan. Sprinkle with remaining 3/4 cup cheese. Cover pan with heavy-duty aluminum foil. Place on a baking sheet.

  5. Bake at 450° for 1 hour. Uncover and bake 25 minutes or until potatoes are done and crust is richly browned. Let stand 10 to 15 minutes. Carefully transfer to a serving plate, and remove sides of pan. If desired, carefully slide gratin off bottom of pan using a long knife or narrow spatula. Garnish, if desired.
