Ingredients

• 6 medium-sized Yukon Gold potatoes
• 2 cups Heavy cream
• 1 cup Whole milk
• 2 tablespoons Dijon mustard
• 2 cloves Garlic
• 1.5 cups Gruyere cheese
• 1 tablespoon Unsalted butter
• 1.5 teaspoons Salt
• 0.5 teaspoon Black pepper
• 1 teaspoon Fresh thyme leaves
• 0.25 teaspoon Nutmeg

Directions

Step 1

Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with 1 tablespoon of butter and set aside.

Step 2

Peel and rinse the potatoes. Using a sharp knife or a mandoline, slice the potatoes into thin, even slices (about 1/8 inch thick). Set aside in a bowl of cold water to prevent discoloration.

Step 3

In a medium saucepan, combine the heavy cream, whole milk, minced garlic, Dijon mustard, salt, black pepper, fresh thyme, and nutmeg. Heat over medium-low until warmed through, stirring occasionally, but do not let it boil.

Step 4

Grate the Gruyere cheese and set aside 1/2 cup for the topping. Mix the remaining 1 cup into the cream mixture until melted. Remove from heat.

Step 5

Drain and pat the potato slices dry. Layer one-third of the potato slices evenly in the prepared baking dish. Pour one-third of the cream mixture evenly over the potatoes. Repeat this process for the next two layers, finishing with the cream mixture on top.

Step 6

Sprinkle the reserved 1/2 cup of Gruyere cheese evenly over the top layer of potatoes.

Step 7

Cover the dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and continue baking for an additional 25-30 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.

Step 8

Let the gratin cool for 10 minutes before serving. Garnish with extra thyme leaves, if desired, for a fresh touch.
