Truffled Mashed Potatoes with Prosciutto and Rosemary

April 23, 2013Katie

These Truffled  Mashed Potatoes with Prosciutto and Rosemary are special potatoes.

They involve special ingredients that deviate from the traditional mashed potatoes with butter and milk. Now, don’t get me wrong I love those kind of potatoes as well! These potatoes involve those “once in awhile” ingredients that make you feel a little over the top…kind of like using lobster or beef tenderloin or saffron. Not your everyday dish kind of ingredients.

But these potatoes, loaded up with things like olive oil, rosemary, prosciutto and garlic along with a nice drizzle of Black Truffle Oil are perfect for an anniversary (mine was yesterday – 8 years!), Mother’s Day, or even Christmas!  They have a bit of an Italian flare and would be fabulous paired with a magnificent steak or Prime Rib.

You start them the same way you would any other mashed potatoes.  With potatoes of course.


Peel them and rinse them off, and cut them up into one inch pieces. Add a tablespoon or so of salt to a pot of water and add in your potato pieces. Did you know you can impart some salt flavor into your potatoes this way?

Make sure the tops of the potatoes are covered with at least an inch of water.


Put it on the stove and crank the heat up to high.  Once the water boils, turn it down to medium or just until it’s bubbling nicely and won’t boil over because, man, you don’t want to clean up that mess!

Let this simmer until sticking a fork into several of the pieces happens very easily without any resistance.

While your pot simmers away making your potatoes nice and tender, open up a package of this loveliness.


When my parents were in Germany years ago, their cousin, whom they stayed with served “something like raw bacon” every morning for breakfast”, said Mom.  I told them it was probably Prosciutto.


I’m not sure entirely that my Mom and “meats that appear to be raw” mesh very well together, and I’m not entirely sure she ever tasted it.  But Prosciutto is cured and absolutely fine to eat as is.

Prosciutto is a little like its cousin bacon or Pancetta, but instead of coming from the belly of the pig, it comes from its hind leg.  While bacon is smoked, prosciutto isn’t, and while bacon and pancetta need to be cooked, prosciutto is dry aged, rubbed with spices and salt and left to cure. You can eat it just like it comes, or you can lightly crisp it in recipes just like bacon, but without the smoky flavor. Feel free to substitute bacon in this recipe if you like!

Take out about 6 slices of Prosciutto and chop it into pretty small pieces.


So, go ahead and get a nonstick skillet and add a tablespoon of olive oil.


Add in your Prosciutto bits. and stir them until they get lightly crispy but not too dark.  When they’re crispy, add in 4 pressed or chopped cloves of garlic.


Also add in 2 tablespoons of chopped rosemary.


Stir this an additional minute but not more and then remove from the stove.

Drain your potatoes and put them right back into the pot.  Add in one cup of milk and the contents of your Prosciutto mixture including any olive oil you might have left in the pan. It’s going to be flavored with garlic and rosemary and be delicious!

Grate up one cup of one of my favorite cheeses in this world – Pecorino Romano.

It’s salty and sharp and full of flavor and I adore it.

Next, add in a teaspoon of salt and 1/2 of cracked black pepper, cuz potatoes need mucho seasoning my friends.

And just because it’s a really special time  for mashed potatoes, add in some white or black truffle oil.

And then take your potato masher and mash everything up really well.

You can mash them up really smoothly by using a mixer if you like, but I prefer the character of some texture in mine.


You can also add a bit more milk if you like them a little more wet.  Each potato will be different, so adjust accordingly!

Just before you serve it, drizzle a tiny bit more truffle oil over the top.


Decadence…pure decadence.
