INGREDIENTS

  • Mashed Potato

    • 6 large russet potatoes, peeled and quartered
    • 🧂 3 tablespoons kosher salt
    • 1/2 cup unsalted butter, cut in pieces
    • 🥛 3/4 cup milk
    • 4 ounces Comte cheese, shredded

  • Au Gratin Layer

    • 4 large russet potatoes, peeled and halved
    • 🧂 2 teaspoons kosher salt
    • 2 tablespoons butter
    • 2 ounces Gruyere cheese (or Cheddar cheese), shredded
    • 1/2 cup Parmigiano-Reggiano cheese

STEPS

1

Preheat the oven to 450°F (230°C). Butter a 13x9-inch baking dish.

2

Add quartered russet potatoes to a pot with 3 tablespoons salt and enough water to cover by 2 inches. Bring to a boil over high heat; reduce heat to medium and simmer until tender, 15 to 20 minutes. Drain very well.

3

Mash the potatoes until almost smooth. Add butter, salt, and cayenne. Mash until smooth. Add milk and shredded Comte cheese, and mash and mix until evenly combined.

4

Spread mashed potatoes evenly into the prepared baking dish, and smooth the top. Season with salt and freshly ground black pepper.

5

Slice each halved potato into 1/8-inch slices and fan them slightly at an angle over the mashed potatoes.

6

Salt the sliced potatoes generously, brush with melted butter, scatter shredded Gruyere cheese on top, and finish with grated Parmigiano-Reggiano.

7

Bake in the preheated oven until sliced potatoes are tender when pierced with a knife, about 1 hour.
