Ingredients
Scale
- 2 lbs Yukon Gold or Russet potatoes, peeled and thinly sliced
- 2 tablespoons unsalted butter
- 2 cloves garlic, minced
- 1 1/2 cups heavy cream
- 1 1/2 cups whole milk
- 2 tablespoons all-purpose flour
- 1 1/2 cups Gruyère cheese, shredded
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon ground nutmeg (optional)
- 1/2 cup Parmesan cheese, grated (optional, for topping)
- Fresh thyme or parsley for garnish (optional)
Instructions
- Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.
- In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
- Stir in the flour and cook for 1-2 minutes to form a roux. Gradually whisk in the milk and heavy cream, making sure to smooth out any lumps.
- Bring the mixture to a simmer, stirring constantly until it thickens, about 5 minutes. Season with salt, pepper, and nutmeg (if using).
- Remove the sauce from the heat and stir in 1 cup of the Gruyère cheese until melted and smooth.
- Layer half of the sliced potatoes in the prepared baking dish. Pour half of the cheese sauce over the potatoes.
- Repeat with the remaining potatoes and the remaining cheese sauce.
- Top with the remaining 1/2 cup of Gruyère cheese and the Parmesan cheese, if using.
- Cover the baking dish with aluminum foil and bake for 45 minutes. After 45 minutes, remove the foil and continue baking for an additional 20-30 minutes, or until the top is golden and the potatoes are tender when pierced with a fork.
- Let the potatoes rest for 10 minutes before serving. Garnish with fresh thyme or parsley, if desired.
Notes
- For extra flavor, you can add finely chopped onions or leeks to the sauce.
- If you prefer a crispier top, broil the potatoes for 2-3 minutes at the end of baking, keeping an eye on them to avoid burning.
- Yukon Gold potatoes are ideal for their creamy texture, but you can also use Russet potatoes for a fluffier result.
