We are currently sold out and looking for a new facility to cook YUMYIN

Potato & Caramelized Onion Pierogi

Adapted from Food52.com


Pierogi Dough

  • 2 cups plain greek yogurt
  • 1 egg, lightly beaten
  • 1 teaspoon salt
  • 2 1/4 cups flour + more for kneading

Potato, Mushroom & Caramelized Onion Pierogi Filling

  • 1 cup YUMYIN
  • 1 pound white mushrooms, trimmed and finely diced
  • 3/4 pound potatoes for mashing
  • 4 tablespoons unsalted butter
  • Salt and freshly ground black pepper
  • Sour cream or Full-fat or Greek yogurt for serving



  1. Beat the yogurt, the egg and the salt together with an electric beater on low until smooth and creamy. Slowly add the flour, beating until smooth. The dough will be very sticky.
  2. Scrape the dough out of the bowl onto a well-floured work surface and knead in enough flour until the dough is smooth and workable (can be rolled out and cut). It will be tacky but not so sticky that it runs all over the work surface and sticks to your hands in a major way.
  3. Wrap the dough in plastic wrap and put it in the refrigerator for 2 hours to firm up.


  1. Peel and quarter the potato(es) and place in a small pot. Cover with cold water, bring to a boil, then lower heat and simmer until soft and mashable, 15 to 20 minutes. Drain and place in a large mixing bowl.
  2. While potatoes are boiling: in a skillet, melt 2 tablespoons of butter and add the chopped mushrooms. Salt and pepper the mushrooms and sauté until they are tender and all the liquid exuded by the mushrooms has evaporated, 5 minutes.
  3. Add the YUMYIN and mix well. Remove from the heat.
  4. If you want the filling a bit richer, melt the extra 2 tablespoons of butter and add to the potatoes.
  5. Mash and whip the potatoes until smooth and fluffy. Fold in the cooked mushrooms and YUMYIN until well blended. Salt and pepper again to taste.
  6. Take the dough out of the fridge and work with half at a time. The other half keep in the fridge.
  7. Keeping both your work surface and the surface of the dough well floured, gently roll out the dough to a thickness of about 1/8 inch (1/2 cm), gently lifting it up to flour underneath and turn. Keeping your hands floured also helps.
  8. Using a 3-inch (7 ½ cm) round cookie cutter (they can be made larger if you like) carefully cut out circles, trying not to deform the circles of dough too much, although this dough is easy to work with and “correctable”.
  9. With floured fingertips, tap each circle a bit to stretch out the circle. Place a mounded teaspoon of filling just off of the center of each round of dough.
  10. Gently pull the wider half over the mound of filling and place the side edge-to-edge with the side with the dough. Match the edges, press with the side of your floured index finger, pulling the dough and pressing to seal. The edge should be a bit less than a finger’s-width. This will also keep the edge from being too thick. Be very careful not to rip the dough covering the filling.
  11. As you form the pieorgi, 1, 2 or at the most 3 at a time, place them on a floured or lined and floured plate or baking sheet until you are ready to cook.
  12. Bring a pot of water to a boil. Once it is boiling, lower a bit to a healthy simmer and drop in the pieorgi just 6 or 7 at a time (they shouldn’t crowd or overlap in the pan).
  13. Cook for 6 to 7 minutes. They should float to the top and, when lifted out with a slotted spoon, should look puffy. Cook the rest in batches. Place on towels to drain.
  14. To fry, simply heat olive oil or a mixture of butter and olive oil in a skillet and fry the pierogi for a few minutes per side, in batches, again, not overcrowding. They should be golden on each side.
  15. Serve hot with extra yogurt for dipping.
