Yes this is the same stuff used to make Tiramisu. It is not sweet, just creamy and yummy. This really works with mashed potatoes and the buttermilk just adds a hint of sourness.

Serves: 4

Mashed Potatoes with Mascarpone and Buttermilk


4 pounds, russet potatoes - peeled and chopped into 1-inch pieces (about 5 large)
6 tablespoons, unsalted butter - cut into 1/2-inch pieces, at room temperature
2 cloves, garlic - peeled and smashed
Kosher salt
1 cup, mascarpone - at room temperature
1/2 cup, buttermilk
Freshly ground black pepper
1 tablespoon, chives - finely chopped


  1. In a 5-quart saucepan, combine the potatoes, 2 tablespoons butter, the garlic, 1 teaspoon salt and enough cold water to cover. Bring to a boil over medium-high heat. Reduce the heat to a simmer and cook until the potatoes are tender, 15 to 20 minutes. Drain in a colander and remove the garlic cloves. Return the potatoes to the pan and, using a potato masher, mash the potatoes until smooth.
  2. Add the mascarpone, buttermilk, the remaining 4 tablespoons butter, 2 teaspoons salt and 1 teaspoon pepper to the potatoes. Stir over low heat until smooth and warmed through. Season with salt and pepper. Transfer to a bowl and serve. Top with finely chopped chives.

Not only is this a delicious alternative to regular mashed potato recipes, but it's a very user-friendly way to serve your potato side dish. They're really decadent: not too rich, but just rich enough, and perfect for any special occasion. If you cannot find mascarpone, don't bother making this there really is no substitute.
