Description

A creamy and cheesy potato gratin, perfect for a comforting side dish!


Ingredients

Scale
  • 2 ½ pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 2 cups heavy cream
  • 1 cup whole milk
  • 3 cloves garlic, minced or smashed
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • ½ teaspoon ground nutmeg
  • 2 teaspoons fresh thyme leaves
  • 1 ½ cups shredded Gruyère cheese
  • 2 tablespoons unsalted butter

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
  2. In a saucepan, combine cream, milk, garlic, thyme, salt, pepper, and nutmeg. Simmer gently for 5 minutes to infuse. Remove from heat.
  3. Slice potatoes into 1/8-inch thick rounds using a mandoline or sharp knife.
  4. Layer one-third of the potatoes in the dish. Pour over one-third of the cream and sprinkle with cheese. Repeat layers twice more.
  5. Cover the dish with foil and bake for 40 minutes. Then uncover and bake for another 25–30 minutes until golden and bubbly.
  6. Let the gratin rest for 10–15 minutes before slicing and serving.

Notes

  • This dish pairs well with roasted meats or a fresh salad.
  • For a richer flavor, try adding more cheese or a sprinkle of breadcrumbs on top before baking.
