Old-Fashioned Potato Gratin

Old-fashioned potato gratin, or au gratin if you want to be technical about things, is a traditional and indulgent manner of keeping yourself warm come cold weather. We’ve never been so grateful for winter.

Old-Fashioned Potato Gratin Recipe

To some, an old-fashioned potato gratin is a gratin is a gratin. We beg to differ. There’s quite the indulgent art to slicing the potatoes just the right thickness so as to become perfectly tender, to finding the perfect proportion of heavy cream to cheese, and to ensuring the time in the oven is just right so the surface of the gratin turns just the perfect shade of irresistible golden brown. In our opinion, this indulgent version defines the very term “potato gratin.” Taste and see for yourself. Originally published December 15, 2010.Renee Schettler Rossi

Old-Fashioned Potato Gratin Recipe

  • Quick Glance
  • 25 M
  • 1 H, 45 M
  • Serves 6


  • 4 russet potatoes
  • 1 garlic clove, crushed and peeled
  • 1 tablespoon unsalted butter, at room temperature
  • Kosher salt and freshly ground white pepper
  • 3 tablespoons freshly grated Comté cheese (or substitute Gruyère or Asiago)
  • 3 tablespoons freshly grated Parmigiano-Reggiano
  • 1 1/2 cups heavy cream


  • 1. Preheat the oven to 350° F (176° C). Adjust the oven rack to the top position.
  • 2. Peel the potatoes and slice them crosswise about 1/8 to 1/4 inch thick. Place the potato slices in a bowl of cold water so they don’t discolor.
  • 3. Meanwhile, firmly rub the garlic clove all over the bottom and sides of a 10-inch gratin dish to coat it with the garlic juices. Allow to dry for a few minutes, then rub the bottom and sides of the dish with the butter.
  • 4. Drain the potatoes and pat them dry. Arrange a layer of potatoes in a slightly overlapping fashion, like a splayed deck of cards, in the bottom of the gratin dish. Season with a good dash of salt and pepper and a little of each of the two cheeses. Continue layering the potatoes and cheese in this fashion, seasoning each layer and finishing with the cheese (you should have at least three layers). Drizzle the cream along the sides of the dish, so as not to displace the cheese.
  • 5. Place the potato gratin, uncovered, on the top rack and bake for 1 to 1 1/4 hours, or until the cream has been absorbed and the top is crispy and golden. Let stand for 10 minutes before serving.

In Advance Advice

  • The peeled potatoes can sit, submerged in cold water, on the counter for a few hours. You can also assemble the gratin, cover it, and refrigerate it for anywhere from a few hours to overnight before baking.
