Servings:
6
  • 4 medium potatoes (peeled and thinly sliced)

  • 2 cups heavy cream (or half-and-half)
  • 1 cup grated Gruyère cheese (or Swiss cheese)
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon nutmeg (freshly grated)
  • 2 tablespoons butter (for greasing the dish)
  • 1 cup bread crumbs (optional topping)
  • 1 cup additional cheese (for topping, optional)

Instructions

8 steps

  1. Preheat the Oven

    Preheat your oven to 375°F (190°C).

    This ensures even cooking.
  2. Prepare the Dish

    Grease a baking dish with butter.

    This will prevent sticking.
  3. Layer the Ingredients

    Arrange half of the sliced potatoes at the bottom of the dish, followed by half of the leeks.

    Ensure even coverage.
  4. Add Seasoning

    Sprinkle salt, pepper, and nutmeg over the layers.

    Adjust seasoning to taste.
  5. Repeat Layers

    Add the remaining potatoes and leeks, then pour the heavy cream over the top.

    Make sure all layers are submerged.
  6. Add Cheese

    Sprinkle the grated Gruyère cheese on top, and add bread crumbs if using.

    This will create a nice crust.
  7. Bake

    Cover with foil and bake for 45 minutes. Remove foil and bake for an additional 15-20 minutes until golden.

    Check for doneness with a fork.
  8. Serve
