Ingredients

• 6 medium Yukon Gold potatoes
• 2 cups Heavy cream
• 1 cup Whole milk
• 1 tablespoon Unsalted butter
• 1 large Garlic clove
• 1.5 cups Gruyère cheese
• 0.5 cup Parmesan cheese
• 2 teaspoons Truffle oil
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 teaspoon Fresh thyme leaves
• 0.25 teaspoon Nutmeg

Directions

Step 1

Preheat your oven to 375°F (190°C). Use the unsalted butter to grease a 9x13-inch baking dish.

Step 2

Peel the potatoes and slice them thinly (approximately 1/8-inch thickness) using a sharp knife or a mandoline slicer. Set aside in a bowl of cold water to prevent browning.

Step 3

In a medium saucepan over medium heat, combine the heavy cream, whole milk, minced garlic, salt, black pepper, nutmeg, and fresh thyme. Heat until warm but not boiling, then remove from heat and set aside.

Step 4

Drain the sliced potatoes and dry them thoroughly with a clean kitchen towel.

Step 5

Arrange one-third of the potato slices in a single, overlapping layer in the prepared baking dish. Sprinkle one-third of the Gruyère and Parmesan cheeses over the layer.

Step 6

Repeat this process for two more layers, finishing with cheese on top.

Step 7

Pour the warm cream mixture evenly over the layered potatoes and cheese. Gently press down to ensure the liquid disperses evenly.

Step 8

Cover the dish with aluminum foil and bake in the preheated oven for 50 minutes.

Step 9

Remove the foil and continue baking for another 20 to 25 minutes, or until the top is golden brown and bubbling.

Step 10

Allow the gratin to cool for 10 minutes before drizzling it with truffle oil.

Step 11

Garnish with a few additional thyme leaves if desired and serve warm.
