Ingredients

• 2 pounds Sweet white potatoes
• 1.5 cups Heavy cream
• 0.5 cup Whole milk
• 2 large Garlic cloves
• 1 teaspoon Fresh thyme
• 0.25 teaspoon Ground nutmeg
• 1 tablespoon Unsalted butter
• 1.5 cups Gruyère cheese
• 0.5 cup Parmesan cheese
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with the unsalted butter and set aside.

Step 2

Peel the sweet white potatoes and slice them into thin, even rounds about 1/8 inch thick. Use a mandoline for best results, or carefully slice with a sharp knife.

Step 3

In a medium saucepan, combine the heavy cream, whole milk, minced garlic, fresh thyme, ground nutmeg, salt, and black pepper. Heat the mixture over medium heat until warm but not boiling. Remove from heat and set aside.

Step 4

Layer one-third of the potato slices in an even layer at the bottom of the prepared baking dish. Pour one-third of the warm cream mixture evenly over the potatoes, then sprinkle one-third of the Gruyère cheese and Parmesan cheese on top.

Step 5

Repeat this layering process two more times, finishing with a top layer of cheese.

Step 6

Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes. Then, remove the foil and bake for an additional 20 minutes, or until the top is golden brown and bubbly.

Step 7

Allow the gratin to cool for 10 minutes before serving. Garnish with additional fresh thyme, if desired, and serve warm.
