Ingredients

For the Gratin

• 2 pounds (1 kg) Yukon Gold or Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
• 1 cup heavy cream
• 1 cup whole milk
• 1 clove garlic, minced
• 1/2 teaspoon ground nutmeg
• 1 teaspoon salt
• 1/2 teaspoon black pepper

For the Cheese Topping

• 1 cup grated Gruyere cheese
• 1/2 cup grated Parmesan cheese
• 1 tablespoon unsalted butter (for greasing the dish)

Optional Garnish

• Fresh thyme sprigs or chopped parsley

Step-by-Step Instructions

Step 1: Preheat the Oven and Prepare the Dish

1. Preheat your oven to 375°F (190°C).
2. Grease a 9×13-inch baking dish with unsalted butter to prevent sticking and enhance flavor.

Step 2: Prepare the Potatoes

1. Peel the potatoes and slice them thinly (about 1/8 inch thick) using a sharp knife or mandoline slicer for uniformity.
2. Place the sliced potatoes in a bowl of cold water to prevent them from browning. Drain and pat them dry with a clean kitchen towel before layering.

Step 3: Make the Cream Mixture

1. In a medium saucepan, combine heavy cream, whole milk, minced garlic, nutmeg, salt, and black pepper.
2. Heat over medium-low heat, stirring occasionally, until the mixture is warm but not boiling. This step infuses the cream with garlic and spices.

Step 4: Assemble the Gratin

1. Arrange half of the potato slices in an even layer in the prepared baking dish.
2. Pour half of the warm cream mixture over the potatoes.
3. Sprinkle half of the Gruyere and Parmesan cheese over the top.
4. Repeat with the remaining potatoes, cream mixture, and cheese, finishing with a generous layer of cheese on top.

Step 5: Bake the Gratin

1. Cover the dish with aluminum foil and bake in the preheated oven for 50 minutes.
2. 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.
3. Let the gratin rest for 10 minutes before serving to allow the sauce to thicken.

Step 6: Garnish and Serve

1. Garnish with fresh thyme sprigs or chopped parsley for a pop of color and added flavor.
2. Serve hot as a side dish or a main course.

Alternative Presentation Ideas

1. Individual Gratin Dishes
   Divide the potatoes and cream mixture into individual ramekins for personalized portions. Perfect for dinner parties!
2. Layered Vegetable Gratin
   Add thinly sliced zucchini, sweet potatoes, or butternut squash for a colorful and flavorful twist.
3. Cheesy Crust Variation
   Top the gratin with a mixture of Gruyere, Parmesan, and breadcrumbs for an extra crispy topping.
4. Rustic Cast-Iron Gratin
   Prepare and bake the gratin in a cast-iron skillet for a rustic, family-style presentation.
5. Mini Appetizer Stacks
   Use a round cookie cutter to cut out small stacks of the baked gratin and serve as elegant appetizers.

Additional Tips for Success

1. Choose the Right Potatoes
   Yukon Gold potatoes are creamy and hold their shape, while Russet potatoes are starchier and create a fluffier texture. Choose based on your preference.
2. Slice Uniformly
   Even slicing ensures that all the potatoes cook at the same rate. A mandoline slicer is the best tool for achieving this.
3. Don’t Skip the Warm Cream
   Warming the cream mixture helps it distribute evenly and reduces cooking time in the oven.
4. Allow Resting Time
   Let the gratin rest for 10 minutes after baking. This step allows the sauce to thicken, making it easier to serve.
5. Use Freshly Grated Cheese
   Pre-grated cheese contains anti-caking agents that can affect melting. Grate your cheese fresh for the best results.

Recipe Variations

1. Herb-Infused Gratin
   Add fresh rosemary, thyme, or chives to the cream mixture for an herby flavor profile.
2. Spicy Gratin
   Sprinkle red pepper flakes or cayenne pepper between the layers for a hint of heat.
3. Truffle Gratin
   Drizzle truffle oil over the top before serving for an indulgent, earthy flavor.
4. Vegan Potato Gratin
   Use plant-based milk, vegan butter, and dairy-free cheese for a vegan-friendly version.
5. Cheddar and Gruyere Gratin
   Swap Parmesan for sharp cheddar to add a bolder, tangier flavor.

Freezing and Storing

Refrigeration

Store leftover gratin in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.

Reheating Tips
