Sweet-Potato Gratins

Tip When buying sweet potatoes, look for small ones that are firm and smooth-skinned, without any soft spots (the large ones are spongier). For a dose of extra fiber, scrub the potatoes under running water and eat them with the skins on.

Sweet-Potato Gratins

12 servings


  • 1 tablespoon unsalted butter, at room temperature
  • 2 large sweet potatoes, peeled and thinly sliced (use a sharp knife, a mandoline, or a food processor with the slicing disc attached)
  • ½ large Idaho potato, peeled and thinly sliced
  • 1 cup heavy cream
  • 1 pinch ground nutmeg
  • 1 pinch freshly ground black pepper
  • Kosher salt to taste
  • 3 ounces Gruyère, grated (about 1 cup)

  1. Preheat oven to 400° F. With the butter, grease a 12-capacity muffin pan.
  2. In a large bowl, toss together the sweet potatoes, Idaho potato, cream, nutmeg, pepper, and salt.
  3. Layer the potato slices in each muffin cup until ¾ full, then top off the muffin cups with any remaining cream. Sprinkle each gratin with some of the cheese. Cover the pan loosely with tinfoil and bake for 20 minutes.
  4. Remove the tinfoil and continue to bake until the potatoes are fork-tender and the cheese is golden brown, 10 to 15 minutes more. Remove and let cool for 5 minutes before serving.
