Martha learned to make these Polish dumplings from her mother, Big Martha, and has been forming and filling pierogi ever since. A smooth, tender dumpling dough made with sour cream encases a filling of boiled and mashed Yukon gold potatoes. The secret ingredient in the filling is cream cheese, which makes the mash rich and smooth. Forming the dumplings is a fun project; you can crimp them in various decorative ways—or keep them simple and classic. They cook quickly and all they need for serving is a generous drizzle of brown butter.
Directions
Make Pierogi Dough:
-
Whisk egg and sour cream, add milk and water:
Make the dough: Whisk together egg and sour cream. Whisk in milk and water.
-
Add flour gradually:
Stir in flour, 1 cup at a time.
-
Knead dough:
Turn out dough onto a floured surface. (Dough will be loose and sticky.) Using a bench scraper, turn and fold dough to knead, dusting with flour as needed, until elastic and no longer sticky, 8 to 10 minutes.
Dough will come together as you knead it. Be careful not to add too much flour as you knead since it will toughen the dough.
-
Rest dough:
Cover with an inverted bowl; let rest for 1 hour.
Make the Filling:
-
Boil potatoes:
While dough rests, place potatoes in a large pot, and cover with cold water. Season with salt. Bring to a boil; cook until fork-tender, 25 to 30 minutes.
-
Rice potatoes
Drain; pass through a ricer.
Potatoes may be mashed as an alternative to ricing but we prefer to rice them as it produces a smoother texture than mashing.
-
Add cream cheese and butter:
Stir cream cheese and butter. Season with salt and pepper.
Form and Cook Pierogi
-
Divide dough and prep baking sheet:
Divide dough into 4 equal pieces. Line a rimmed baking sheet with a clean linen towel, and dust generously with cornmeal to prevent sticking.
-
Roll one piece of dough:
Roll out 1 piece of dough on a lightly floured surface into a 1/8-inch-thick round (keep other pieces covered).
-
Cut out circles of dough:
Cut out circles very close together, using a 3-inch cutter or glass. Cover with plastic wrap to prevent dough from drying. Repeat with remaining dough.
-
Boil water:
Bring a large pot of salted water to a boil.
-
Fill pierogi:
Place a 1 1/2-inch oval (about 1 tablespoon plus 2 teaspoons) filling in center of each dough circle.
-
Form pierogi around filling:
Holding 1 circle in your hand, fold dough over filling. Pinch edges, forming a well-sealed crescent.
-
Cover filled pierogi:
Transfer to cornmeal-dusted towel, and loosely cover with plastic wrap. Repeat with remaining dough circles and filling.
-
Make brown butter:
Melt butter in a small saucepan over medium heat, swirling occasionally, until dark golden brown, 8 to 10 minutes.
-
Cook pierogi:
Working in batches, transfer pierogi to boiling water. They will sink to the bottom and then rise. Once they have risen, cook through, about 2 minutes more.
-
Drizzle with brown butter for serving:
Coat a platter with half the brown butter. Transfer pierogi to platter using a slotted spoon. Drizzle tops with remaining butter, and season with salt.
