Ingredients

• 2 pounds Russet potatoes
• 3 tablespoons Unsalted butter
• 3 tablespoons All-purpose flour
• 2 cups Whole milk
• 1 cup Heavy cream
• 2 cloves Garlic (minced)
• 2 cups Gruyere cheese (shredded)
• 1 cup Parmesan cheese (grated)
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg (optional)
• 2 sprigs Fresh thyme (for garnish)

Directions

Step 1

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

Step 2

Peel the russet potatoes and slice them thinly (about 1/8-inch thick) using a sharp knife or mandoline for even slices. Set aside in cold water to prevent browning.

Step 3

In a medium saucepan over medium heat, melt the unsalted butter. Stir in the all-purpose flour and cook for 1-2 minutes, whisking continuously, to form a smooth roux.

Step 4

Gradually pour in the whole milk and heavy cream while whisking to prevent lumps. Keep whisking until the mixture thickens, about 4-5 minutes.

Step 5

Add the minced garlic, Gruyere cheese, Parmesan cheese, salt, black pepper, and nutmeg (if using) to the saucepan. Stir until the cheese is melted and the sauce is velvety smooth. Remove from heat.

Step 6

Drain and pat dry the potato slices thoroughly. Spread one-third of the potatoes evenly in the prepared baking dish.

Step 7

Pour one-third of the cheese sauce over the potato layer, spreading it evenly. Repeat the layering process with the remaining potatoes and cheese sauce, finishing with a layer of cheese sauce on top.

Step 8

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

Step 9

Remove the foil, sprinkle a bit of extra Gruyere or Parmesan cheese on top (optional), and bake uncovered for an additional 20-25 minutes or until the top is golden and bubbly, and the potatoes are fork-tender.

Step 10

Let the dish rest for 10 minutes before serving. Garnish with fresh thyme sprigs for a pop of flavor and presentation.
