• 2 pounds russet potatoes (about 4 large potatoes)
• 1 cup heavy cream
• 1 cup whole milk
• 1 garlic clove, minced
• 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)

• ½ teaspoon black pepper
• 1 cup grated Gruyere cheese
• 1 cup grated Parmesan cheese
• 2 tablespoons unsalted butter, softened
• 1 tablespoon olive oil

Ingredient Highlights

• Gruyere Cheese: Gruyere is known for its nutty, slightly sweet flavor that melts beautifully, adding richness to the gratin.

Step-by-Step Instructions

Here’s how to make Crispy Parmesan and Gruyere Potato Gratin:

Prepare the Gratin:

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Butter a 9×13-inch baking dish or gratin dish with softened butter to prevent sticking.
2. Prepare the Potatoes: Peel the russet potatoes and slice them into thin, even rounds (about ⅛-inch thick). You can use a mandolin slicer to ensure uniform thickness.
3. Make the Cream Mixture: In a medium saucepan, combine the heavy cream, milk, minced garlic, thyme, salt, and pepper. Bring the mixture to a simmer over medium heat, stirring occasionally. Once it’s simmering, remove it from the heat and set aside.
4. Layer the Potatoes: Arrange a layer of potato slices at the bottom of the prepared baking dish. Overlap the slices slightly to create a uniform layer. Pour about ¼ of the cream mixture over the potatoes and sprinkle with ¼ of the Gruyere and Parmesan cheeses.
5. Continue Layering: Repeat the layering process, alternating between potatoes, cream mixture, and cheeses, until all the ingredients are used. Finish with a final layer of cheese on top for an extra crispy crust.
6. Drizzle with Olive Oil: Drizzle the olive oil evenly over the top layer of cheese to help it crisp up during baking.

Bake the Gratin:

7. Bake: Cover the baking dish with aluminum foil and bake for 45 minutes. After 45 minutes, remove the foil and bake for an additional 20-25 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
8. Cool and Garnish: Once the gratin is done, remove it from the oven and let it cool for a few minutes. Garnish with fresh parsley for a pop of color before serving.

Additional Tips for Crispy Parmesan and Gruyere Potato Gratin
