The magic of this recipe lies in the preparation method. By boiling the potatoes first and then smashing them before roasting, you create maximum surface area for the herb-infused cream and melted cheese to cling to, ensuring every bite is packed with flavor.

Ingredients

• Potatoes: 1.5 kg (3.3 lbs) small Yukon Gold or baby potatoes
• 1 tbsp olive oil
• Salt and freshly ground black pepper, to taste
• Cream Mixture: 1 1/2 cups (360 ml) heavy cream
• 2 cloves garlic, minced
• 1 tsp fresh thyme leaves (or 1/2 tsp dried)
• 1/2 tsp fresh rosemary, finely chopped
• 1/2 tsp ground nutmeg
• Cheeses: 1 cup (100 g) Gruyère cheese, grated
• 1 cup (100 g) mozzarella cheese, grated
• 1/2 cup (50 g) Parmesan cheese, grated
• Garnish: 2 tbsp fresh chives or parsley, chopped

Instructions

Step 1

Preheat oven to 220°C (425°F). Line a large baking sheet with parchment paper.

Step 2

Place whole potatoes in a large pot, cover with salted water, and bring to a boil. Cook until fork-tender, 15–18 minutes.

Step 3

Drain potatoes and let cool slightly. Transfer to the prepared baking sheet. Use a potato masher or the bottom of a glass to gently smash each potato to about 1 cm (1/2 inch) thick.

Step 4

Drizzle smashed potatoes with olive oil and season generously with salt and pepper. Roast in the oven for 20 minutes, or until edges are crisp and golden.

Step 5

Meanwhile, in a small saucepan over low heat, combine heavy cream, garlic, thyme, rosemary, and nutmeg. Heat gently until just warmed and fragrant; do not boil.

Step 6

Arrange half the roasted smashed potatoes in a buttered baking dish. Pour over half of the cream mixture and sprinkle with half the Gruyère, mozzarella, and Parmesan.

Step 7

Layer the remaining potatoes, then top with the rest of the cream and cheeses.

Step 8

Bake in the oven (still at 220°C/425°F) for 20–25 minutes, or until bubbly and golden brown on top.

Step 9

Let rest for 10 minutes before garnishing with fresh herbs and serving.

Zusatztipps für die Zubereitung

When smashing the potatoes, aim for a thickness of about 1 cm to ensure they stay intact while roasting. Using a large pot for boiling and a sturdy baking sheet is essential. For the best texture, ensure the potatoes are fully tender before you attempt to smash them.

Varianten und Anpassungen

For a lighter version of this gratin, you can substitute half-and-half for the heavy cream. To add extra depth, try layering in caramelized onions or sautéed mushrooms between the potatoes. If you don't have Gruyère, Emmental is a great alternative, and mozzarella can be swapped for Fontina if desired.

Serviervorschläge

This luxurious side dish pairs beautifully with roasted meats like beef or chicken. To serve it as a vegetarian main, pair it with a crisp green salad tossed in a sharp vinaigrette to balance the richness of the cream and cheese layers.
