Ingredients

• 6 medium-sized Yukon Gold potatoes
• 2 cups Gruyere cheese, grated
• 1 cup Creme fraiche
• 1 cup Heavy cream
• 1 tablespoon Unsalted butter
• 2 cloves Garlic, minced
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.25 teaspoon Nutmeg, grated
• 1 teaspoon Fresh thyme leaves (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Grease a 9x13-inch baking dish with the unsalted butter, ensuring even coverage on the bottom and sides.

Step 3

Peel the Yukon Gold potatoes and slice them thinly—ideally about 1/8-inch thick—using a mandoline slicer or a sharp knife.

Step 4

In a medium mixing bowl, whisk together the creme fraiche, heavy cream, minced garlic, salt, black pepper, and grated nutmeg (add the fresh thyme leaves here, if using). Set aside.

Step 5

Arrange one-third of the sliced potatoes in an even layer at the bottom of the prepared baking dish. Pour one-third of the creme fraiche mixture over the potatoes, spreading it evenly with a spatula or spoon.

Step 6

Sprinkle one-third of the grated Gruyere cheese over the top of the creme fraiche layer.

Step 7

Repeat this layering process two more times with the remaining potatoes, creme fraiche mixture, and Gruyere cheese, finishing with cheese on top as the final layer.

Step 8

Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 50 minutes, allowing the potatoes to cook and become tender.

Step 9

After 50 minutes, remove the foil and continue baking for another 20-25 minutes, or until the top is golden brown and bubbly.

Step 10

Remove the gratin from the oven and allow it to rest for 10 minutes before serving, as this will help the dish set and make it easier to slice.

Step 11

Serve warm as a side dish or enjoy it on its own as a comforting meal.
