Ingredients

• 6 medium Russet potatoes
• 4 tablespoons Unsalted butter
• 3 cloves Garlic, minced
• 3 tablespoons All-purpose flour
• 2.5 cups Whole milk
• 0.5 cups Heavy cream
• 1.5 teaspoons Salt
• 0.5 teaspoons Black pepper
• 2 cups Gruyère cheese, shredded
• 1 cup Sharp cheddar cheese, shredded
• 2 tablespoons Fresh parsley, chopped (optional garnish)

Directions

Step 1

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

Step 2

Peel the potatoes and slice them into thin, even rounds (about 1/8-inch thick). A mandoline slicer works well for this step.

Step 3

In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 30 seconds, until fragrant.

Step 4

Whisk in the flour to form a roux and cook for 1 to 2 minutes, stirring constantly, to cook out the raw flour taste.

Step 5

Gradually whisk in the milk and heavy cream, ensuring no lumps form. Cook over medium heat, stirring frequently, until the mixture thickens, about 5 to 7 minutes.

Step 6

Stir in 1 teaspoon of salt, the black pepper, and 1 1/2 cups of the Gruyère cheese. Stir until the cheese is melted and the sauce is smooth. Remove the saucepan from heat.

Step 7

Layer half of the sliced potatoes evenly in the prepared baking dish. Sprinkle the remaining 1/2 teaspoon salt over the potatoes.

Step 8

Pour half of the cheese sauce evenly over the first potato layer. Spread it gently with a spatula if needed.

Step 9

Repeat with the remaining potatoes and the rest of the cheese sauce, ensuring the top layer is fully coated.

Step 10

Sprinkle the sharp cheddar cheese and the remaining 1/2 cup of Gruyère cheese over the top layer.

Step 11

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

Step 12

Remove the foil and continue to bake for an additional 25 to 30 minutes, or until the top is golden and the potatoes are tender when pierced with a knife.

Step 13

Allow the dish to rest for 10 minutes before serving. Garnish with fresh parsley, if desired.
