Ingredients

Potatoes
8-9 medium starchy potatoes (about 1.2kg), thinly sliced
Opt for varieties like Russet or Maris Piper for their excellent baking qualities. Using a mandoline slicer ensures uniform, thin slices that cook evenly.
Garlic:
1 head garlic, top trimmed
Roasting the garlic mellows its sharpness, imparting a sweet, caramelized flavor to the dish.
Dairy:
1 cup (250 ml) heavy cream (double cream)
Provides a rich and creamy texture to the sauce.
1/4 cup (60 ml) whole milk
Balances the richness of the cream and helps achieve the desired sauce consistency.
1 tablespoon unsalted butter, plus extra for greasing
Adds silkiness to the sauce and prevents sticking.
Cheeses:
1/2 cup (40g) grated Parmesan cheese, divided
Offers a nutty flavor and contributes to the golden crust.
2 cups (about 220g) shredded Gruyère or mozzarella cheese
Ensures a gooey, melty layer; Gruyère adds a slightly sweet, earthy note, while mozzarella provides a milder taste.
Seasonings:
1 teaspoon fresh thyme leaves (or 1/3 teaspoon dried thyme)
Introduces an aromatic, earthy flavor complementing the garlic and cheese.
1/4 teaspoon ground nutmeg
Enhances the depth of flavor in the creamy sauce.
Salt and freshly ground black pepper, to taste
Season according to preference, keeping in mind the saltiness of the cheeses.

Directions

Roast the Garlic:
Preheat the oven to 350°F (180°C).
Place the trimmed garlic head on a piece of aluminum foil, drizzle with a bit of olive oil, and season lightly with salt. Wrap tightly and roast for about 30 minutes until the cloves are soft and golden. Once cooled, squeeze the roasted garlic cloves out of their skins and mash into a paste.
Prepare the Baking Dish and Potatoes:
Increase the oven temperature to 375°F (190°C).
Grease a 9×13-inch (23×33 cm) baking dish with butter.
Peel and thinly slice the potatoes, aiming for uniform thickness. Arrange the slices upright in the prepared baking dish, forming neat rows.
Make the Creamy Sauce:
In a saucepan over medium heat, combine the heavy cream, milk, butter, half of the grated Parmesan cheese, thyme, nutmeg, and the mashed roasted garlic. Stir continuously until the butter melts and the mixture is well combined. Season with salt and pepper to taste.
Assemble the Dish:
Pour the creamy sauce evenly over the arranged potato slices, ensuring all are well-coated. Cover the dish tightly with aluminum foil.
Bake:
Bake in the preheated oven for 40 minutes.
After 40 minutes, remove the foil, sprinkle the shredded Gruyère (or mozzarella) and the remaining Parmesan over the top. Return to the oven and bake uncovered for an additional 30 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
Serve:
Allow the dish to rest for about 10 minutes before serving. This resting period helps the sauce thicken slightly and makes for easier serving.
