Ingredients

Scale
  • 2 pounds Yukon Gold or Russet potatoes, peeled and sliced thin (about 1/8 inch or 3 mm)
  • 8 ounces Gruyere cheese, grated
  • 2 cups heavy cream
  • 3 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon fresh thyme, finely chopped (optional)
  • Pinch of nutmeg

Instructions

  1. Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with 1 tablespoon of butter.
  2. Slice the potatoes thinly using a mandoline or sharp knife into 1/8-inch (3 mm) rounds. Rinse slices in cold water and pat dry to remove excess starch.
  3. In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add minced garlic and sauté for about 1 minute until fragrant but not browned.
  4. Pour in 2 cups heavy cream, then stir in onion powder, salt, black pepper, thyme (if using), and nutmeg. Whisk gently and warm the mixture until just simmering, stirring occasionally.
  5. Add half of the grated Gruyere cheese and stir until melted and smooth. Remove from heat.
  6. Layer half of the potato slices evenly in the baking dish. Pour half of the cheese sauce over the potatoes, then sprinkle a handful of the remaining Gruyere cheese on top. Repeat layering with remaining potatoes, sauce, and cheese, finishing with a thick cheese layer.
  7. Cover the baking dish with aluminum foil.
  8. Bake for 40 minutes. Remove the foil and bake uncovered for an additional 15 minutes until the top is bubbly and golden.
  9. Check tenderness by poking the potatoes with a knife; they should be tender and creamy inside.
  10. Let the dish cool for 10 minutes before serving to allow layers to set.

Notes

Use a mandoline for even thin slices to ensure even cooking. Warm the cream gently to avoid curdling. Let the dish rest for 10 minutes before serving for cleaner slices. If the top browns too quickly, lower oven temperature to 350°F and extend baking time. For a thicker sauce, add 1 tablespoon cornstarch mixed into the cream. For dairy-free, substitute heavy cream with coconut cream and use vegan cheese alternatives.
