Kasia’s Potato and Cheese Pierogi is our most popular flavor. The dumpling is stuffed with freshly whipped Idaho potatoes and the finest farmer’s cheese thus creating a truly classic taste. Because all of our pierogi are pre-cooked, just brown the pierogi in a skillet and serve with sour cream. Another popular way to prepare this favorite is to top the browned pierogi with melted butter and sautéed onions. If you have never tried Kasia’s Pierogi before, this is a good place to start.
