Instructions

1. Preheat oven to 375°F (190°C). Butter a 9×13 inch baking dish.
2. In a large bowl, whisk together the heavy cream, whole milk, minced garlic, ½ teaspoon salt, ¼ teaspoon black pepper, and ¼ teaspoon nutmeg.
3. Add the thinly sliced potatoes to the cream mixture. Gently toss to coat all the potato slices evenly.
4. Pour half of the potato and cream mixture into the prepared baking dish, spreading it out evenly.
5. Evenly sprinkle 1 cup of the shredded Gruyère cheese and ½ cup of the shredded sharp cheddar cheese over the potatoes.
6. Pour the remaining potato and cream mixture over the cheese layer, spreading it out evenly.
7. Evenly sprinkle the remaining 1 cup of Gruyère cheese and ½ cup of sharp cheddar cheese over the top.
8. Drizzle the melted butter evenly over the top layer of cheese.
9. Bake for 50-60 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.
10. Let the au gratin rest for 10-15 minutes before serving.

Notes

Once completely cooled, store leftover au gratin in an airtight container in the refrigerator for 3-4 days. Reheat in the oven at 350°F (175°C) for 15-20 minutes, covered, then uncovered to crisp the top.
