Kasia’s Potato and Onion Pierogi is our second most popular item. These dumplings are stuffed with freshly whipped Idaho potatoes and freshly sautéed onions. By taking the popular Potato and Cheese pierogi and replacing the cheese with sauteed onions we have created a healthy and tasty alternative to a classic. Whether boiled or browned, a great way to complement this flavor is to serve Kasia’s Potato and Onion Pierogi with bacon bits and melted butter or sour cream.
