Polish Pierogi: Potato and Cheese Dumplings

Pierogi ruskie are Polish dumplings filled with mashed potatoes, farmer cheese, and onion, then boiled and often served with buttery onions and sour cream. Their tender dough and savory filling make a satisfying meal, and the filling can be prepared ahead; households and regions have their own variations rather than one single definitive version.

Ingredients

4 cups (500 g) all-purpose flour, plus a little extra for rolling
1 large egg (about 50 g)
1 cup (240 ml) warm water
2 tablespoons (28 g) unsalted butter, melted and cooled slightly
1 teaspoon (6 g) fine salt for the dough
1½ pounds (680 g) russet or Yukon Gold potatoes, peeled and cut into 1-inch pieces
8 ounces (225 g) farmer cheese, crumbled
1 medium yellow onion (about 150 g), finely diced for the filling
1 tablespoon (14 g) unsalted butter for the filling
½ teaspoon (1 g) ground black pepper
½ teaspoon (3 g) fine salt for the filling, plus more to taste
2 medium yellow onions (about 300 g), thinly sliced for serving
2 tablespoons (28 g) unsalted butter for the topping
1½ cups (360 g) sour cream, for serving
4 quarts (3.8 L) water and 1 tablespoon (18 g) salt for boiling the pierogi

Instructions

Make the dough. Put the flour and 1 teaspoon of salt in a large bowl. In a separate bowl, whisk the egg, warm water, and melted butter. Pour the liquid into the flour gradually, stirring with a fork or sturdy spoon until a shaggy dough forms. Tip it onto a lightly floured counter and knead for about 8 minutes, until smooth and supple. If it feels very sticky, dust the counter with flour a teaspoon at a time; if it feels dry or cracks when pressed, knead in water a teaspoon at a time. Shape the dough into a ball, cover it with an inverted bowl or plastic wrap, and let it rest at room temperature for 30 minutes. Resting relaxes the dough so it rolls without springing back.
Cook the potatoes. Put the potato pieces in a saucepan and cover them with cold water by about 1 inch. Bring to a boil, reduce the heat to maintain a steady simmer, and cook for 15–18 minutes, until a fork slides easily into the largest piece. Drain thoroughly, return the potatoes to the warm pan, and let steam escape for a minute. Dry potatoes make a firmer filling that is less likely to leak through the dumplings.
Prepare the filling. While the potatoes cook, melt 1 tablespoon of butter in a skillet over medium heat. Add the finely diced filling onion and cook for about 8 minutes, stirring often, until soft and lightly golden; lower the heat if it begins to brown too quickly. Mash the drained potatoes until mostly smooth, then mix in the farmer cheese, cooked onion, pepper, and ½ teaspoon of salt. Taste a small amount and adjust the seasoning. The filling should be savory and fairly thick, not loose or wet. Let it cool enough to handle while you roll the dough.
Roll and cut. Divide the rested dough into 2 pieces and keep one covered while working with the other. On a lightly floured surface, roll the dough to about ⅛ inch (3 mm) thick. Cut circles about 3 inches (7.5 cm) across with a cutter or the rim of a glass. Gather and reroll the scraps once; repeated rerolling can make the dough tougher. Repeat with the second piece. You should have roughly 36–40 circles, depending on how thinly you roll and how efficiently you use the scraps.
Fill and seal. Place about 1 level tablespoon of filling in the center of each circle. Keep the filling away from the edge so the seam can close cleanly. Fold the dough over to make a half-moon, press the edges together from the center outward, and pinch firmly all the way around. If the dough edge has dried, dampen it very lightly with water. Check each dumpling for gaps, and set the finished pierogi on a flour-dusted tray without letting them touch. Avoid overfilling: a small, well-sealed dumpling is less likely to split than one packed to the edge.
Cook the onions for serving. Melt the remaining 2 tablespoons of butter in a skillet over medium-low heat. Add the thinly sliced onions and cook for about 12 minutes, stirring regularly, until softened and golden in places. Keep the heat moderate so the onions turn sweet and tender instead of scorching. Set the skillet aside while you boil the pierogi.
Boil the pierogi. Bring 4 quarts of water and 1 tablespoon of salt to a gentle boil in a large pot. Cook the dumplings in batches, leaving room for them to move; crowding the pot can make them stick together. Stir once gently after adding a batch. When they float, cook them for about 2 more minutes, usually 3–4 minutes total per batch, then lift them out with a slotted spoon. Boil the batches steadily rather than at a violent rolling boil, which can damage the seams. Because the dough contains egg, check a pierogi from the first batch with a food thermometer; the USDA FSIS safe minimum for egg dishes is 160°F (71°C) at the center.
Serve. Transfer the boiled pierogi to a platter, spoon the warm onion and butter over them, and serve with sour cream. If you prefer a browned surface, see the variation below rather than leaving the dumplings in the boiling water longer than needed.

Tips

Choose a suitable cheese. Farmer cheese gives the filling a pleasantly tangy, slightly crumbly texture. If it is hard to find, use full-fat cottage cheese drained in a fine sieve until it is no longer watery, then crumble or mash it. Cottage cheese is softer and can make the filling looser, so drain it well and avoid adding extra liquid.
Keep the dough covered. Dough exposed to air dries quickly, and dry edges are harder to seal. Cover unused portions and cut circles with a clean towel while you fill each batch. A thin dusting of flour prevents sticking, but too much flour on the edges can keep them from sealing.
Check the filling before assembling. Taste and season it while it is still easy to mix. If it is warm, that is fine, but very hot filling can soften the dough and make shaping awkward. If it seems loose, let it cool and drain away any liquid rather than trying to compensate with a large amount of flour.
Make the shape consistent. Use about the same amount of filling in each dumpling and press out trapped air before pinching the seam shut. Air pockets expand in hot water and can put pressure on the seam. Keep finished pierogi in a single layer until they are ready for the pot.

Serving Suggestions

Serve pierogi ruskie hot with the browned, buttery onions and a generous spoonful of sour cream. The soft potato-cheese filling is rich, so a crisp green salad, sliced cucumber with dill, or lightly dressed cabbage makes a refreshing contrast. Pickled cucumbers or sauerkraut are also common-style accompaniments when you want something tart and crunchy alongside the dumplings.

For a more substantial meal, serve a moderate portion with a simple vegetable soup or a platter of roasted beets. Fresh dill or chopped chives can be scattered over the top, but the onions are flavorful enough to stand on their own. Put extra sour cream and black pepper on the table so diners can season their portions as they like. If you are serving a group, keep the first batches warm in a covered dish while the remaining pierogi cook; avoid piling them tightly together, because steam can make them stick.

Variations

Brown the boiled pierogi. After boiling and draining, let the dumplings sit briefly so excess water runs off. Melt a little butter in a skillet over medium heat and fry them in a single layer for a few minutes per side, until lightly browned. Work in batches so they sear rather than steam. Serve with the onion topping or use the skillet in place of the topping pan.

Use a different potato. Russets make a fluffy, easy-to-mash filling, while Yukon Gold potatoes give it a naturally buttery texture. Either works; avoid waxy potatoes if you want a smooth filling, since they can stay firm and slightly gluey when mashed.

Adjust the filling to taste. Some cooks use more cheese, a little extra onion, or a pinch of marjoram. Start with small changes so the filling remains thick enough to seal inside the dough. For a less tangy flavor, choose a mild farmer cheese; for more tang, use a sharper cheese that still crumbles well.

Make smaller dumplings. Cut 2½-inch (6 cm) circles and use about 2 teaspoons of filling for a smaller, party-size version. They cook quickly, so check them as soon as they float and keep the batch size modest. Smaller pierogi take longer to shape, but are convenient as a side dish or for a buffet.

Storage and Reheating

For cooked leftovers, refrigerate the pierogi and onion topping within 2 hours of cooking, ideally in separate airtight containers. They keep for 3–4 days in the refrigerator. Reheat leftovers in a skillet with a little butter over medium heat, turning until hot throughout, or microwave them covered with a teaspoon of water to reduce drying. Reheat to 165°F (74°C), as recommended for leftovers; check the center of a dumpling with a food thermometer. The microwave softens the surface, while the skillet gives it a lightly crisp outside.

To freeze uncooked pierogi, arrange them in one layer on a parchment-lined tray and freeze until firm, then transfer them to a freezer-safe bag or container. Cook them from frozen in gently boiling water, adding a few minutes and waiting until they float and are cooked through; do not thaw them first, since thawing can make the dough sticky. Cooked pierogi can also be frozen, though their texture may be a little softer after thawing. For best quality, use frozen pierogi within about 2 months. Discard cooked dumplings that have been left at room temperature for more than 2 hours.

Frequently Asked Questions

Can I make pierogi dough ahead?
Yes. Wrap the dough tightly and refrigerate it for up to 24 hours. Let it sit at room temperature for about 20–30 minutes before rolling, because cold dough is firmer and can be difficult to roll evenly. The filling can also be made a day ahead and kept covered in the refrigerator; bring it out while you roll the dough so it is easier to portion.

Why did my pierogi open in the pot?
Common causes are overfilling, trapped air, a dry edge, or a seam that was not firmly pinched. Use a level tablespoon of filling, press gently around the filling to push out air, and check the entire edge before boiling. A gentle boil also helps; vigorous bubbling can knock dumplings into one another and stress the seam.

Can I cook pierogi without boiling them first?
For this recipe, boil them first so the dough cooks evenly and the filling heats through. You can then pan-fry the boiled dumplings for a browned finish. Frying raw pierogi directly is not a reliable shortcut because the outside can brown before the dough and center are fully cooked.

What can I use instead of farmer cheese?
Well-drained full-fat cottage cheese is the easiest substitute. Drain it in a fine sieve until excess whey stops collecting, then break up the curds before mixing. It will usually make the filling a little softer and less crumbly than farmer cheese. Ricotta can also work if drained thoroughly, although its mild flavor and creamy texture make the result less tangy.

Can I freeze the dumplings before cooking?
Yes. Freeze shaped, uncooked pierogi in a single layer until firm, then pack them in a freezer-safe container so they do not stick together. Boil them straight from frozen in batches; do not thaw them on the counter. Allow a few extra minutes and confirm they are hot and cooked through before serving.

Are pierogi ruskie the same as Russian dumplings?
No. The name is sometimes misunderstood: “ruskie” is associated historically with Ruthenian regions, not a claim that this potato-and-cheese filling comes from modern Russia. Pierogi are strongly associated with Polish cooking, and their shapes, fillings, and toppings vary between regions and households.
