Mashed Potatoes with Prosciutto and Parmesan Cheese

Methods of mashed potato preparation are constantly reimagined, and this incarnation of the beloved dish stands with the best of them. The recipe, a perfect side for pork chops, draws on traditional Italian ingredients: aged Parmesan for pungency, thinly sliced and chopped prosciutto for texture, and fresh rosemary as the finishing touch.

Recipe information

  • Yield

    Makes 8 servings

Ingredients

3 1/4 pounds russet potatoes, peeled, cut into 1-inch pieces
4 large garlic cloves, peeled
1/2 cup (1 stick) butter
3 1/2 ounces thinly sliced prosciutto, finely chopped
3/4 teaspoon minced fresh rosemary, plus additional for garnish
3/4 cup whole milk, or more as needed
1 cup freshly grated Parmesan cheese (about 3 ounces)

Preparation

  1. Step 1

    Cook potatoes and garlic in a large pot of boiling salted water until the potatoes are very tender, about 15 minutes. Drain; return the potatoes and garlic to the same pot.

    Step 2

    Meanwhile, melt the butter in a heavy small saucepan over medium heat. Add the prosciutto and 3/4 teaspoon minced rosemary and sauté until fragrant, about 2 minutes.

    Step 3

    Add the prosciutto mixture and the milk to the potatoes and garlic. Mash well, adding more milk by tablespoonfuls if potatoes are dry. Mix in 3/4 cup cheese. Season with salt and pepper.

    Step 4

    Transfer the potatoes to a bowl. Sprinkle with the remaining 1/4 cup cheese; garnish with fresh rosemary and serve.

  2. DO AHEAD

    Step 5

    The MASHED POTATOES (through step 3) can be prepared 6 hours ahead. Cover and chill. Stir over low heat to rewarm, adding more milk by tablespoonfuls, if desired.
