Gratin de Pommes de Terre Au Four

Ingredients

• Butter (2 tablespoons, melted (for greasing))
• Salt (to taste)
• Black pepper (to taste)
• Fresh thyme (1 tablespoon, chopped)
• Garlic (2 cloves, minced)
• Parmesan cheese (1 cup, grated)
• Gruyère cheese (1 cup, grated)
• Heavy cream (2 cups)
• Potatoes (3-4 large, peeled and thinly sliced)

Instructions

1. Preheat the oven to 375°F (190°C).
2. In a saucepan, combine the heavy cream, minced garlic, and chopped fresh thyme. Heat over medium heat until it starts to simmer, then remove from heat and let it steep for 5 minutes.
3. Grease a baking dish (about 9x13 inches) with melted butter.
4. Layer half of the thinly sliced potatoes in the baking dish, ensuring an even distribution. Season generously with salt and black pepper.
5. Pour half of the cream mixture over the potatoes, spreading it evenly to coat all slices.
6. Sprinkle half of the grated Gruyère and Parmesan cheese over the cream mixture, ensuring coverage across the potatoes.
7. Repeat the layering process with the remaining potatoes, followed by the rest of the cream mixture, and finish with the remaining cheeses on top.
8. Cover the baking dish tightly with foil and bake in the preheated oven for 40 minutes.
9. After 40 minutes, remove the foil and bake for an additional 20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
10. Allow the gratin to cool for a few minutes before serving. Enjoy this creamy and cheesy delight!
