→ Main Ingredients

01 - 3 tablespoons butter

02 - 1 small onion, finely diced

03 - 1 clove garlic, minced or grated

04 - 1 teaspoon fresh thyme, chopped or 1/2 teaspoon dried thyme

05 - 3 tablespoons flour (use gluten-free flour for a gluten-free option)

06 - 1 1/2 cups milk or heavy cream

07 - 1 1/2 cups Gruyere cheese, shredded

08 - 1 pinch nutmeg, optional

09 - Salt and pepper to taste

10 - 4 pounds potatoes, thinly sliced

# Steps:

01 - Melt the butter in a saucepan over medium heat. Add the onion and cook until tender, approximately 3-5 minutes. Add the garlic and thyme, cooking until fragrant, approximately 1 minute.

02 - Sprinkle in the flour, mix well, and cook until it starts to turn lightly golden brown, about 1 minute.

03 - Gradually add the milk, stirring constantly. Cook until the sauce thickens, approximately 1-2 minutes. Reduce the heat and add 1/2 cup of the shredded Gruyere cheese. Stir until melted. Incorporate nutmeg if using and season with salt and pepper to taste.

04 - Spread a thin layer of sauce on the bottom of a large baking dish. Layer the potato slices with sauce in between each layer. Optionally, dip each slice into the sauce as you place it into the dish.

05 - Pour any remaining sauce over the layered potatoes in the dish. Sprinkle the remaining shredded cheese on top. Bake in a preheated oven at 350°F (180°C) until the potatoes are tender, approximately 45-60 minutes.

# Notes:

01 - For a richer flavor, replace milk and flour with heavy cream.

02 - Feel free to use any favorite melting cheese, such as Swiss, mozzarella, Havarti, or cheddar.

03 - Try additional cheese varieties like Parmesan, Asiago, or Pecorino Romano for extra flavor.

04 - Both russet and Yukon gold potatoes work well for this dish.

05 - Arrange the potatoes vertically for a striking presentation, dipping slices in sauce before placing them in the dish.
