By pre-roasting the smashed potatoes before adding the cream, you ensure that the texture remains interesting rather than just soft. The olive oil helps the edges catch the heat, creating those sought-after caramelized bits that contrast beautifully with the bubbling cheese topping.

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: Prep

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

Step 2: Boil

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: Smash

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: Roast

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: Infuse

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: Layer

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: Final Layer

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

Step 8: Bake

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

Step 9: Serve

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

Zusatztipps für die Zubereitung

For the best results, use a potato masher to get an even thickness of about 1 cm, which ensures even roasting. Heating the cream mixture gently without boiling is crucial; it helps the garlic and herbs infuse into the fat of the cream, ensuring the flavor is distributed throughout the entire dish.

Varianten und Anpassungen

You can easily customize this gratin by swapping the cheeses. Try Emmental instead of Gruyère or Fontina for a different melt. For those looking for extra depth, layering in caramelized onions or sautéed mushrooms adds a savory earthiness. For a lighter version, you can substitute half-and-half for the heavy cream.

Serviervorschläge

This luxurious gratin pairs wonderfully with roasted meats like steak or herb-crusted chicken. To balance the richness of the cream and cheese, serve it alongside a crisp green salad with a sharp lemon vinaigrette. Garnish generously with fresh chives or parsley right before bringing it to the table.
