Ingredients

  • 2 1/2 pounds (1.2 kilograms) potatoes
  • 4 tablespoons grated Pecorino Romano
  • 7 tablespoons (100 grams) butter, cut into pieces
  • 2 eggs
  • 1/2 teaspoon salt
  • 1/2 teaspoon grated nutmeg
  • 1 dash freshly ground black pepper, to taste
  • 10 1/2 ounces (300 grams) fresh mozzarella
  • 3 1/2 ounces (100 grams) gorgonzola or blue cheese
  • 1 cup (150 grams) prosciutto cotto, thinly sliced
  • 3 tablespoons bread crumbs
  • 1 tablespoon extra virgin olive oil

Directions

  1. 1
    Peel the potatoes and cut them into 1/2-inch-thick slices. Steam the sliced potatoes in a pressure cooker for about 6 to 7 minutes. Alternatively, you can also boil the potatoes; in this case leave them whole, so they will absorb less water.
  2. 2
    Preheat the oven to 350° F.
  3. 3
    Mash the steamed potatoes in a bowl with a potato ricer. Mix the potatoes while they are still hot with the butter, eggs, grated Pecorino, salt, pepper, and nutmeg. Use a fork to make a creamy, smooth texture.
  4. 4
    Grease an 9 x 9-inch baking dish or oven-safe pot and sprinkle with half of the bread crumbs. Spoon half of the mashed potatoes on the bottom and flatten the surface with a spatula.
  5. 5
    Cover the potatoes with the prosciutto cotto and scatter the surface with pieces of mozzarella and gorgonzola. Top with the rest of the mashed potatoes, then flatten the surface with a spatula. Dust the surface with breadcrumbs, then drizzle with extra virgin olive oil.
  6. 6
    Bake until golden and crisp, about 45 to 50 minutes, and serve warm.
