These Roasted Garlic Potatoes au Gratin are a creamy, cheesy side dish layered with thin slices of starchy potatoes and a rich roasted garlic cream sauce. Topped with Gruyère and Parmesan, this golden, bubbly dish is perfect for dinner parties, holidays, or cozy family meals.

Ingredients

Scale
  • 8–9 medium starchy potatoes (about 1.2 kg), thinly sliced
  • 1 head garlic, top sliced off
  • 1 cup (250 ml) heavy cream
  • 1/4 cup (60 ml) whole milk
  • 1 tablespoon unsalted butter, plus more for greasing
  • 1 teaspoon fresh thyme leaves (or 1/3 tsp dried)
  • 1/4 teaspoon nutmeg
  • 1/2 cup (40g) grated Parmesan cheese, divided
  • 2 cups (220g) shredded Gruyère or mozzarella
  • Salt and pepper to taste
  • Fresh chives, for garnish

Instructions

1. Preheat oven to 375°F (190°C).

2. Slice off the top of the garlic head, drizzle with olive oil, wrap in foil, and roast for 30 minutes until soft and golden.

3. Grease a 9×13-inch (23×33 cm) baking dish with butter. Peel and thinly slice potatoes with a mandoline slicer.

4. Layer potatoes upright in the baking dish.

5. In a saucepan, combine cream, milk, butter, half the Parmesan, thyme, nutmeg, salt, and pepper. Warm until butter melts (do not boil).

6. Squeeze roasted garlic into a bowl, mash into a paste, and stir into the cream mixture.

7. Pour the garlic cream over the potatoes. Cover tightly with foil.

8. Bake for 40 minutes.

9. Uncover, sprinkle Gruyère and remaining Parmesan on top.

10. Return to oven and bake uncovered for 30 minutes until golden and bubbly.

11. Let rest for a few minutes before serving. Garnish with fresh chives.

Notes

• Store leftovers in an airtight container in the refrigerator for up to 3 days.

• Do not boil the cream mixture – it should just be warm enough to melt the butter and infuse the flavors.

• Use a mandoline for even potato slices – this helps with uniform cooking.
