Ingredients

• 6 large Russet potatoes
• 2 cups Heavy cream
• 1 cup Whole milk
• 4 tablespoons Unsalted butter
• 3 cloves Garlic
• 2 teaspoons Fresh thyme leaves
• 2 teaspoons Salt
• 1 teaspoon Black pepper
• 2 cups Gruyère cheese
• 1 cup Parmesan cheese
• 2 tablespoons Fresh parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or nonstick cooking spray and set aside.

Step 2

Peel the potatoes and slice them thinly (approximately 1/8-inch thick) using a sharp knife or a mandoline slicer. Place the slices in a bowl of cold water to prevent them from browning while preparing other ingredients.

Step 3

In a medium saucepan, combine the heavy cream, whole milk, butter, minced garlic, thyme leaves, salt, and black pepper. Heat over medium heat, stirring occasionally, until the butter is melted, and the mixture is warm but not boiling. Remove from heat.

Step 4

Drain and pat the potato slices dry with a clean kitchen towel or paper towels.

Step 5

Spread a thin layer of the cream mixture (about 1/4 cup) on the bottom of the prepared baking dish. Arrange one layer of potato slices over the cream, slightly overlapping each slice.

Step 6

Sprinkle about 1/3 of the Gruyère cheese and 2 tablespoons of Parmesan cheese over the potato layer. Pour about 1/3 of the cream mixture evenly over the top.

Step 7

Repeat the layering process (potatoes, cheeses, cream) two more times, finishing with a final layer of cheese on top.

Step 8

Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 60 minutes, then remove the foil and bake for an additional 25-30 minutes, or until the top is golden and bubbly, and a knife easily pierces through the potatoes.

Step 9

Let the potato bake cool for at least 10 minutes before serving. Garnish with fresh parsley if desired and serve warm.
