Ingredients

Scale
  • 2 lbs Yukon Gold or Russet potatoes, thinly sliced
  • 2 cups heavy cream
  • 2 cloves garlic, minced
  • 2 tbsp unsalted butter
  • ½ tsp nutmeg
  • 1 tsp salt
  • ½ tsp black pepper
  • Fresh thyme or rosemary for garnish

Instructions

  • Preheat the oven to 375°F (190°C).
  • Prepare the potatoes by peeling (if desired) and slicing them thinly.
  • Infuse the cream: In a saucepan, heat the heavy cream, garlic, nutmeg, salt, and pepper over low heat until warm. Do not boil.
  • Layer the potatoes in a buttered baking dish, slightly overlapping.
  • Pour the warm cream mixture over the potatoes, ensuring they are well-coated.

  • Garnish with fresh herbs before serving.

Notes

  • Use a mandoline slicer for even, thin potato slices.
  • Let the gratin rest for 10 minutes before serving to thicken.
  • Traditional gratin dauphinois does not include cheese, but you can add Gruyère if desired.
