A cozy, easy-to-make side dish featuring tender potatoes layered with a rich, creamy Gruyere cheese sauce. Perfect for busy weeknights or holiday feasts.

Ingredients

Scale
  • 2 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
  • 1 ½ cups Gruyere cheese, shredded
  • 2 cups heavy cream
  • 3 tablespoons unsalted butter, melted
  • 2 cloves garlic, minced
  • 1 small yellow onion, finely chopped (optional)
  • Salt to taste (about 1 teaspoon)
  • Black pepper to taste (about ½ teaspoon)
  • 1 teaspoon fresh thyme leaves (optional)
  • A pinch of nutmeg

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or non-stick spray.
  2. Thinly slice peeled potatoes to about 1/8 inch thickness using a mandoline or sharp knife.
  3. In a medium bowl, whisk together heavy cream, melted butter, minced garlic, salt, pepper, thyme leaves, and nutmeg.
  4. Arrange a single layer of potato slices at the bottom of the baking dish, slightly overlapping.
  5. Sprinkle a third of the chopped onion (if using) and a third of the shredded Gruyere evenly over the potatoes.
  6. Repeat layering potatoes, onions, and cheese, then pour a third of the cream mixture over each layer until all ingredients are used, finishing with cheese on top.
  7. Cover the dish tightly with aluminum foil and bake for 45 minutes.
  8. Remove foil carefully and bake uncovered for an additional 20 minutes or until the top is golden and bubbly and potatoes are tender.
  9. Let the scalloped potatoes rest for 10 minutes before serving to thicken and set.

Notes

If the top browns too quickly, tent loosely with foil. For a lighter version, substitute half-and-half for heavy cream. This dish can be prepped ahead and refrigerated for up to 24 hours before baking; add 10 minutes to baking time if baking from cold. Use a sharp knife if no mandoline is available. Freshly shred Gruyere for best melting and flavor.
