Leftover mashed potatoes make this Pierogi Pizza a Pittsburgh favorite.
Pierogi Pizza is definitely one of those “only in America” concepts that sounds strange at first. Strange that is, until you take a bite of your first slice. Thanks to our fellow potato-loving friends at the US Potato Board (which I believe I should be a card-carrying member of), we are paying homage to our “hometown” of Pittsburgh, where pierogies and pierogi pizza are practically a food group.
Pittsburgh is home to many Eastern European immigrants, and plenty of great food as a result. Pierogies are a favorite food in our house and a staple on many menus, even at concession stands at local sporting events. The first time I took Jackie to a Pirates game, she laughed hysterically at the famous “Great Pierogi Race”, where mascots dressed up as this delicious local treat race around the stadium between innings.
The funny thing about pierogi pizza is that there are no actual pierogies used. Instead it relies on the familiar flavor combination of creamy mashed potatoes, sautéed onions, and a blend of cheeses, all nestled together on a great-tasting crust. Having made my share of pierogies and pierogi pizzas, I feel uniquely qualified to share this hometown recipe with you.
We started with one of my personal favorites, red bliss potatoes, as a base for our Amazing Mashed Potatoes. Our readers know that I always make enough mashed potatoes for days’ worth of leftovers, and this Pierogi Pizza is a great way to use them. Make no mistake about it though, it is also great on its own. As strange as the name may sound, it boils down to a few of my favorite ingredients: potatoes, cheese, onions and pizza crust.
