Ingredients

Scale
  • 2 pounds (900g) russet potatoes, peeled and thinly sliced
  • 1 ½ cups (about 150g) Gruyere cheese, shredded
  • 3 tablespoons unsalted butter, divided
  • 3 tablespoons all-purpose flour
  • 2 cups (480ml) whole milk
  • 1 cup (240ml) heavy cream
  • 2 cloves garlic, minced
  • 1 teaspoon salt, plus more to taste
  • ½ teaspoon freshly ground black pepper
  • 1 teaspoon fresh thyme, chopped (optional)
  • Pinch of nutmeg

Instructions

  1. Preheat your oven to 375°F (190°C). Butter your baking dish thoroughly.
  2. Peel and slice the russet potatoes about 1/8-inch (3mm) thick. Set aside in a bowl of cold water.
  3. In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add minced garlic and cook for about 1 minute until fragrant.
  4. Whisk in the flour and cook for about 2 minutes to form a roux, without browning.
  5. Slowly pour in the milk and cream while whisking constantly. Cook and whisk until sauce thickens and coats the back of a spoon, about 5-7 minutes.
  6. Remove from heat and stir in shredded Gruyere cheese gradually until melted. Season with salt, pepper, thyme (if using), and nutmeg. Adjust seasoning to taste.
  7. Drain and pat dry the potato slices. Arrange them in overlapping layers in the buttered baking dish.
  8. Pour the creamy Gruyere sauce evenly over the potatoes.
  9. Dot the remaining 1 tablespoon of butter on top.
  10. Bake uncovered for 50-60 minutes, until potatoes are tender and top is bubbly and golden brown.
  11. Let rest for 10 minutes before serving.

Notes

Use a mandoline for even potato slices to ensure creamy texture. Whisk constantly when adding milk to avoid lumps. Stir cheese off heat to prevent oiliness. Tent with foil if top browns too fast. Let dish rest before serving for easier slicing.
