Ingredients

• 6 medium Russet potatoes
• 4 tablespoons Unsalted butter
• 2 cloves Garlic
• 3 tablespoons All-purpose flour
• 2 cups Whole milk
• 1 cup Heavy cream
• 1.5 teaspoons Salt
• 0.5 teaspoons Ground black pepper
• 0.5 teaspoons Dried thyme
• 1.5 cups Gruyère cheese, shredded
• 0.5 cups Parmesan cheese, grated
• 2 tablespoons Fresh parsley (optional, for garnish)

Directions

Step 1

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

Step 2

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

Step 3

In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 1 minute until fragrant.

Step 4

Whisk in the flour and cook for 1–2 minutes to form a roux, ensuring it doesn’t turn brown.

Step 5

Gradually pour in the milk and heavy cream, whisking constantly to avoid lumps. Continue cooking the sauce until it thickens, about 3–4 minutes.

Step 6

Stir in salt, pepper, and thyme. Remove the saucepan from heat and stir in 1 cup of shredded Gruyère cheese until melted and smooth.

Step 7

Drain and pat the potato slices dry. Arrange one-third of the potato slices in an even layer in the prepared baking dish.

Step 8

Pour one-third of the cheese sauce over the potatoes, spreading it evenly. Repeat with two more layers of potatoes and cheese sauce.

Step 9

Sprinkle the remaining 0.5 cups of Gruyère and the grated Parmesan evenly on top of the final layer.

Step 10

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

Step 11

Remove the foil and bake for an additional 25–30 minutes, or until the top is golden brown and bubbling.

Step 12

Let the scalloped potatoes cool for 10 minutes before serving. Garnish with fresh parsley, if desired.
