🥘 Ingredients

11 items

• 6 medium-sized Yukon Gold potatoes
• 3 tablespoons Unsalted butter
• 2 tablespoons All-purpose flour
• 2 cups Milk
• 1 cup Heavy cream
• 2 cloves Garlic
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1.5 cups Gruyere cheese
• 0.5 cups Parmesan cheese
• 1 teaspoon Fresh thyme

📝 Instructions

11 steps

1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

2. Peel the Yukon Gold potatoes and use a mandoline or sharp knife to slice them into 1/8-inch thick rounds. Set aside.

3. In a medium saucepan over medium heat, melt the butter. Once melted, add the flour and whisk constantly for 1 minute to form a roux.

4. Slowly whisk in the milk and heavy cream, ensuring no lumps form. Continue whisking until the mixture thickens, about 3-4 minutes.

5. Mince the garlic cloves and stir them into the milk mixture along with the salt, black pepper, and thyme. Cook for another minute, then remove the saucepan from heat.

6. Stir in 1 cup of the Gruyere cheese and all of the Parmesan cheese until melted and fully incorporated.

7. Arrange a layer of potato slices at the bottom of the prepared baking dish, slightly overlapping them. Pour a small amount of the cheese sauce evenly over the potatoes.

8. Continue layering the potatoes and cheese sauce until all ingredients are used, finishing with a layer of cheese sauce on top.

9. Sprinkle the remaining 0.5 cup of Gruyere cheese over the top of the dish.

10. Cover the dish with aluminum foil and bake for 40 minutes. Then, remove the foil and bake for an additional 30-35 minutes, or until the top is golden and the potatoes are tender when pierced with a fork.

11. Allow the Potatoes Au Gratin to cool for 10 minutes before serving. Garnish with additional thyme if desired.
