Ingredients

Scale
  • 2 lbs Yukon Gold potatoes, thinly sliced (about 1/8-inch thick)
  • 1 ½ cups heavy cream
  • ½ cup whole milk
  • 2 cups shredded Gruyere cheese, divided
  • 3 cloves garlic, minced
  • 2 tablespoons unsalted butter, plus more for greasing
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper
  • ¼ teaspoon freshly grated nutmeg
  • Fresh thyme sprigs for garnish (optional)

Instructions

  1. Preheat your oven to 400°F (200°C). Grease a 9×13-inch baking dish with butter.
  2. Slice the potatoes thinly (about 1/8-inch thick) using a mandoline or sharp knife. Place slices in a bowl of cold water to prevent browning.
  3. In a medium saucepan over medium heat, melt the butter. Add minced garlic and cook for 30 seconds until fragrant. Pour in heavy cream and milk. Whisk in salt, pepper, and nutmeg. Bring to a gentle simmer (do not boil).
  4. Drain potato slices and pat dry. Arrange a single layer of potatoes in the greased dish. Pour about ⅓ of the cream sauce over the top. Sprinkle with about ⅓ of the shredded Gruyere. Repeat layering two more times, ending with a final layer of cheese on top.
  5. Cover the dish tightly with aluminum foil. Bake for 20 minutes. Remove foil and bake for another 10-15 minutes, until top is golden brown and bubbly and potatoes are tender when pierced with a fork.
  6. Let the dish rest for at least 5 minutes before serving to allow the sauce to thicken.

Notes

Let the dish rest for at least 5 minutes after baking to allow the sauce to thicken. For best results, shred Gruyere from a block rather than using pre-shredded cheese. The nutmeg is a secret ingredient that adds warmth—don’t skip it. You can assemble the dish up to a day in advance and refrigerate; add 10-15 minutes to baking time if starting from cold.
