Ingredients
  • 2 lbs Russet Potatoes
  • 2 cups Heavy Cream
  • 1 cup Gruyere Cheese
  • 2 cloves Garlic
  • 2 tablespoons Butter
  • 1/4 teaspoon Nutmeg
  • 1 teaspoon Salt
  • 1/2 teaspoon Black Pepper

Prepare the Potatoes

Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish with butter. Peel the potatoes and slice them thinly, about 1/8 inch thick. A mandoline slicer can be helpful for even slices. Place the sliced potatoes in a bowl of cold water to prevent browning.

Make the Cream Sauce

In a saucepan, melt the remaining 2 tablespoons of butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute. Pour in the heavy cream and bring to a simmer. Season with salt, pepper, and freshly grated nutmeg. Reduce heat to low and simmer for 5 minutes, stirring occasionally.

Assemble the Gratin

Drain the potatoes thoroughly and pat them dry with paper towels. Layer a third of the potato slices in the prepared baking dish, overlapping slightly. Pour a third of the cream sauce over the potatoes, ensuring they are evenly coated. Sprinkle a third of the shredded Gruyere cheese over the sauce. Repeat the layers two more times, finishing with a layer of cheese on top.

Bake the Gratin

Cover the baking dish with aluminum foil and bake for 30 minutes. Remove the foil and continue baking for another 20-30 minutes, or until the potatoes are tender and the top is golden brown and bubbly. Let the gratin rest for 10-15 minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together.

FAQ

  • Can I use different types of cheese?

    Yes, Gruyere is classic, but you can substitute it with other cheeses like cheddar, Swiss, or Parmesan. A combination of cheeses can also add depth of flavor.
  • Can I make this ahead of time?

    Yes, you can assemble the gratin ahead of time and store it in the refrigerator for up to 24 hours. Add an extra 15-20 minutes to the baking time when cooking from cold.
  • How do I prevent the potatoes from browning before baking?

    Submerge the sliced potatoes in cold water immediately after slicing. This helps to remove excess starch and prevents oxidation.
