Ingredients

• 2.5 pounds Russet potatoes
• 3 tablespoons Unsalted butter
• 2 cloves Garlic cloves, minced
• 2.5 tablespoons All-purpose flour
• 2.5 cups Whole milk
• 1 cup Heavy cream
• 2 tablespoons Dijon mustard
• 1.5 teaspoons Salt
• 0.5 teaspoon Ground black pepper
• 1 teaspoon Fresh thyme leaves
• 1.5 cups Shredded Gruyere cheese
• 0.5 cups Shredded Parmesan cheese
• 2 tablespoons Chopped 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 and thinly slice the potatoes (about 1/8-inch thick). Use a mandoline slicer for even slices if you have one. Place the slices in a large bowl of cold water to prevent them from browning while preparing the sauce.

Step 3

In a large saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 1-2 minutes until fragrant, but not browned.

Step 4

Sprinkle the flour into the saucepan, whisking constantly to make a roux. Cook the roux for 1-2 minutes until lightly golden.

Step 5

Gradually add the milk and heavy cream to the saucepan, whisking constantly to avoid lumps. Bring the mixture to a simmer, stirring frequently, until it thickens (approximately 3-4 minutes).

Step 6

Whisk in the Dijon mustard, salt, pepper, and thyme. Remove the saucepan from the heat and stir in 1 cup of the Gruyere cheese until melted and smooth. Reserve the remaining 1/2 cup Gruyere cheese and the Parmesan cheese for topping.

Step 7

Drain the potato slices and pat them dry with a clean kitchen towel. Layer half of the potato slices in the prepared baking dish, overlapping slightly.

Step 8

Pour half of the Dijon cheese sauce evenly over the potatoes. Repeat with the remaining potatoes and sauce, ensuring all slices are covered.

Step 9

Sprinkle the reserved Gruyere cheese and Parmesan cheese evenly over the top of the dish.

Step 10

Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes.

Step 11

Remove the foil and continue baking for an additional 30-40 minutes, or until the potatoes are tender and the top is golden and bubbling.

Step 12

Let the dish rest for 5-10 minutes before serving. Garnish with chopped parsley, if desired, and serve warm.
