Ingredients

Scale

Main Ingredients:

  • 2 lbs (900 g) potatoes (Yukon Gold or Russet), peeled and thinly sliced
  • 2 cups (480 ml) heavy cream
  • 1 cup (100 g) grated Gruyere cheese (or a mix of cheeses)
  • 1 cup (100 g) grated Parmesan cheese

Seasonings and Aromatics:

  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 pinch of nutmeg (optional)

Preparation Ingredient:

  • 2 tablespoons unsalted butter, for greasing

Instructions

  1. Prepare the baking dish by greasing with butter and set oven temperature to 375F (190C).
  2. Rinse potato slices in cold water to prevent discoloration and drain thoroughly.
  3. Whisk together heavy cream, minced garlic, salt, pepper, and nutmeg in a mixing bowl until well combined.
  4. Create the first potato layer in the greased baking dish, ensuring even coverage.
  5. Drizzle cream mixture over potato layer, ensuring uniform distribution.
  6. Sprinkle grated cheese across the initial layer to enhance flavor and texture.
  7. Repeat layering process with remaining potatoes, cream mixture, and cheese, building multiple tiers.
  8. Ensure the final layer is topped with a generous cheese coating for golden crust development.
  9. Cover the baking dish completely with aluminum foil to retain moisture during initial baking.
  10. Bake for 45 minutes while covered to allow potatoes to soften and absorb cream mixture.
  11. Remove foil and continue baking for 25-30 minutes until surface turns golden brown and edges become crispy.
  12. Remove from oven and let gratin rest for 15 minutes to stabilize and set before serving.
  13. Slice and serve warm, allowing guests to enjoy the rich, creamy potato layers.

Notes

  • Pat potatoes dry thoroughly after soaking to ensure crispy, golden edges and prevent soggy texture.
  • Use a mandoline slicer for uniformly thin potato slices, which helps create even cooking and consistent layers.
  • Experiment with different cheese combinations like Gruyère, Parmesan, or sharp cheddar to add depth and complexity to the flavor profile.
  • For a lighter version, substitute half-and-half or whole milk for heavy cream, reducing overall calories without sacrificing creaminess.
