Roasted Garlic Potatoes au Gratin is a rich and creamy side dish featuring thinly sliced potatoes layered with roasted garlic, cream, and melted cheese. Baked until golden and bubbly, it’s perfect for holidays or cozy family dinners.

Ingredients

  • 2 lbs Yukon Gold potatoes, thinly sliced
  • 1 head garlic
  • 1 tablespoon olive oil
  • 1 ½ cups heavy cream
  • 1 ½ cups shredded Gruyère cheese
  • ½ cup grated Parmesan cheese
  • 2 tablespoons butter
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ¼ teaspoon ground nutmeg
  • Fresh thyme, for garnish (optional)

Instructions

  1. Preheat oven to 400°F (200°C). Cut the top off the garlic head, drizzle with olive oil, wrap in foil, and roast for 30–35 minutes until soft. Let cool, then squeeze out the garlic cloves and mash into a paste.
  2. Reduce oven temperature to 375°F (190°C). Grease a baking dish with butter.
  3. In a saucepan, combine heavy cream, mashed roasted garlic, salt, pepper, and nutmeg. Heat over medium until warm (do not boil).
  4. Layer half of the sliced potatoes in the baking dish. Pour over half of the cream mixture, then sprinkle with half the Gruyère and Parmesan.
  5. Repeat with the remaining potatoes, cream, and cheeses.
  6. Cover with foil and bake for 40 minutes. Remove foil and bake an additional 20–25 minutes until golden and bubbly.
  7. Let rest for 10 minutes before serving. Garnish with fresh thyme if desired.

Notes

  • Use a mandoline slicer for even potato slices.
  • Can be prepared a day in advance and reheated before serving.
  • Swap Gruyère for sharp cheddar or Swiss cheese if preferred.
  • Adjust garlic quantity based on your taste.
