Ukrainian Vareniki Recipe with Potato and Cheese

Ukrainian vareniki are soft, filled dumplings made from simple dough and commonly served with sour cream, butter, or fried onions. This version pairs creamy potatoes with tangy farmer cheese for a satisfying filling that holds together well, while the dough is tender and easy to shape; families and regions make vareniki with many different fillings.

Ingredients

4 cups (500 g) all-purpose flour, plus a little extra for rolling
1 large egg (about 50 g without shell)
1 cup (240 ml) warm water
1 tablespoon (15 ml) neutral oil, such as sunflower or canola oil
1 teaspoon (6 g) fine salt for the dough
1½ pounds (680 g) russet or Yukon Gold potatoes, peeled and cut into 1-inch (2.5 cm) pieces
1 medium yellow onion (about 150 g), finely chopped
2 tablespoons (28 g) unsalted butter for the filling
1 cup (225 g) farmer cheese, crumbled
½ teaspoon (2 g) fine salt for the filling, plus more to taste
¼ teaspoon (0.5 g) black pepper
3 tablespoons (42 g) unsalted butter for serving
1 cup (240 g) sour cream, for serving
2 tablespoons (6 g) chopped fresh dill, optional
Water for boiling, about 4 quarts (3.8 L), and 1 tablespoon (15 g) salt for the pot

Farmer cheese gives the filling a pleasantly tangy, slightly crumbly texture and is sold in some grocery stores and Eastern European markets. If it is unavailable, use the same amount of small-curd cottage cheese, drained in a fine sieve for 20 to 30 minutes; it will make the filling softer and a little wetter. If the cottage cheese still looks loose, mash it with the potatoes and avoid adding any extra liquid.

Instructions

Mix the dough, about 10 minutes. Put the flour and 1 teaspoon salt in a large bowl. In a separate cup, whisk the egg with the warm water and oil. Pour the liquid into the flour, stirring with a fork or your hand until a rough dough forms. Turn it onto a lightly floured counter and knead for about 8 minutes, until smooth and elastic. It should feel soft but not sticky. If it clings to your hands, work in flour a tablespoon at a time; if it feels dry or cracks, dampen your hands and knead again rather than pouring in a lot of water at once.
Rest the dough, 30 minutes. Shape the dough into a ball, cover it with an overturned bowl or wrap it well, and leave it at room temperature for 30 minutes. Resting relaxes the dough so it rolls out without springing back. Keep it covered while you prepare the filling so the surface does not dry and form a crust.
Cook the potatoes, 18 minutes. Put the potato pieces in a saucepan and cover them with cold water by about 1 inch (2.5 cm). Bring to a boil, add a generous pinch of salt, then simmer for about 18 minutes, or until a knife slides easily into the largest piece. Drain thoroughly and return the potatoes to the warm pan for a minute so excess steam can escape. A dry potato base makes a filling that is easier to portion and less likely to leak.
Make the filling, about 16 minutes. While the potatoes drain, melt the 2 tablespoons butter in a skillet over medium heat. Add the chopped onion and cook for about 6 minutes, stirring, until soft and lightly golden; do not let it burn. Mash the potatoes until mostly smooth, then stir in the onion and its butter, farmer cheese, ½ teaspoon salt, and pepper. Taste and adjust the seasoning. Let the filling cool until it is comfortable to handle, about 10 minutes. The filling should be thick enough to mound on a spoon; if it is loose, chill it briefly or mix in a little more farmer cheese.
Roll, fill, and seal the vareniki, about 30 minutes. Divide the rested dough in half and keep one half covered. On a lightly floured counter, roll the other half to about ⅛ inch (3 mm) thick. Cut rounds about 3 inches (7.5 cm) across with a glass or cutter. Gather and reroll scraps once; repeated rerolling can make the dough tougher. Place about 1 level tablespoon of filling in the center of each round. Fold it over into a half-moon, press out air around the filling, and pinch the edges firmly together. If the edge will not stick, touch it with a little water, then seal again. Set finished dumplings on a lightly floured tray without letting them touch. Repeat with the remaining dough and filling; you should get about 36 vareniki.
Boil in batches and serve. Bring about 4 quarts (3.8 L) water to a steady boil in a large pot and add 1 tablespoon salt. Add the vareniki in batches, giving them room to move; overcrowding can make them stick or tear. Stir gently once just after adding them. When they rise to the surface, cook for another 3 to 4 minutes, until the dough is tender and the filling is hot. About three batches should take roughly 12 minutes of cooking time in total. Because the dough contains egg, the USDA FSIS safe minimum for egg dishes is 160°F (71°C), checked with a food thermometer; check the center of a cooked dumpling if you need to verify doneness. Lift the dumplings out with a slotted spoon, drain briefly, and toss gently with the 3 tablespoons butter so they do not stick. Serve hot.

Tips

Keep the dough covered. Dough exposed to air dries quickly, and dry edges are difficult to seal. Cover both the resting dough and the rounds you are not filling yet. Use only enough flour to prevent sticking; too much flour on the edges can also make them hard to pinch closed.
Seal carefully, not forcefully. Press out trapped air before pinching the half-moon shut, then check the seam for gaps. Too much filling is a common cause of bursting, so use a level tablespoon and leave a clear border around each round.
Adjust for your cheese. Farmer cheese and cottage cheese vary in moisture and saltiness. Drain cottage cheese well, taste the filling before shaping, and season it as needed. A wet filling is harder to seal; a very dry filling can be loosened with a teaspoon of sour cream.
Make a small test batch. Boil two or three dumplings first. If one opens, press the remaining seams more firmly or use slightly less filling. If the dough seems firm, give the test batch another minute in the water before adjusting the rest.

Serving Suggestions

Serve vareniki immediately while the dough is tender and the potato-cheese center is warm. Set out sour cream and chopped dill, and offer black pepper at the table. For a more traditional-style finish, spoon melted butter over the dumplings and scatter on golden sautéed onions; crisp fried onions add a little sweetness and texture. A side of sauerkraut or a simple cucumber salad makes a fresh, tangy contrast to the rich filling.

For a larger meal, serve a moderate portion alongside roasted or braised vegetables. The dumplings are filling on their own, so a small salad, pickled vegetables, or sliced tomatoes is often enough. If serving a crowd, keep cooked batches warm in a buttered covered dish while the remaining vareniki boil, and toss them gently between batches to keep them separate. Avoid leaving them sitting in hot water, where they can become waterlogged.

Variations

Potato and farmer cheese is a popular filling, but vareniki are made with many savory and sweet fillings. For a cheese-forward version, increase the farmer cheese to 1½ cups (340 g) and reduce the potato to 1 pound (450 g). For a simpler potato filling, omit the cheese and add another tablespoon of butter and extra cooked onion. The cheese-free version tastes more like buttery mashed potato, so season it generously.

For a seasonal option, use finely chopped, sautéed cabbage in place of some of the potato. Cook the cabbage until soft and let it cool before mixing it into the filling; wet or warm filling is more likely to break the dough. Cooked mushrooms with onion also make a savory filling, but chop them finely and cook away their moisture first. For sweet vareniki, use a fruit filling such as pitted cherries or sweetened farmer cheese, and serve with sour cream or a little sugar. Sweet versions often need a different filling quantity and careful sealing, so avoid overfilling the dough rounds.

You can also change the dough slightly. A tablespoon of sour cream in the dough can make it a little richer and softer; reduce the water by about 1 tablespoon (15 ml) to start, then add only enough to bring the dough together. For a dairy-free filling, omit the butter and farmer cheese and use well-seasoned potatoes with sautéed onions in oil. The result will be less tangy and creamy, but it still holds together when the potatoes are mashed until smooth.

Storage and Reheating

Refrigerate cooked vareniki within 2 hours of cooking in a covered container. They keep for 3 to 4 days in the refrigerator. Store them with a light coating of butter or oil to reduce sticking. Reheat leftovers in a skillet over medium-low heat with a small pat of butter, turning gently until hot throughout, or microwave them covered with a teaspoon of water to prevent drying. Reheat leftovers to 165°F (74°C), as recommended by USDA FSIS.

Uncooked vareniki freeze well. Arrange them in a single layer on a lightly floured or parchment-lined tray, freeze until firm, then transfer them to a freezer-safe bag or container. For best texture, use within about 2 months. Cook from frozen without thawing, adding them to boiling salted water in batches; they will take longer than fresh dumplings, often about 5 to 7 minutes after they float. Check that the dough is tender and the filling is hot before serving. Do not leave cooked dumplings at room temperature for more than 2 hours.

Frequently Asked Questions

What is the difference between vareniki and pierogi?
Vareniki is the Ukrainian name for filled dumplings, while pierogi is commonly used for similar dumplings in Polish cooking. The dishes share a basic idea, but dough, fillings, names, and serving customs vary by country, region, and household. This recipe makes Ukrainian-style vareniki with a potato and farmer-cheese filling.

Can I make the dough or filling ahead?
Yes. The filling can be prepared up to 1 day ahead and kept covered in the refrigerator; let it cool before storing. You can also make the dough a few hours ahead and keep it tightly covered at room temperature, or refrigerate it overnight. If chilled, allow it to sit at room temperature for about 20 minutes before rolling so it is easier to work with.

Why are my vareniki opening in the pot?
Common reasons are overfilling, air trapped around the filling, a dry edge, or a seam that was not firmly pinched. Use a level spoonful, press out air as you fold, and moisten a dry edge with a fingertip dipped in water. Boil in batches at a steady boil rather than stirring vigorously, which can damage the seams.

Can I use store-bought dough?
For the closest texture, make the dough in this recipe; it is designed to roll thin and seal around the filling. If using another dumpling or pasta dough, check that it can be cut into 3-inch rounds and sealed without cracking. Thicker wrappers may need a little longer to cook, so use the texture of the dough and a cut-open dumpling to judge doneness.

How many vareniki should I serve per person?
This recipe makes about 36 dumplings, or roughly 6 per person for 6 servings. Serve more if the dumplings are the main course and fewer alongside several substantial sides. The exact yield depends on how thinly you roll the dough and the size of your cutter.

Can I cook the vareniki straight from frozen?
Yes. Do not thaw them first, since thawing can make the dough damp and fragile. Add frozen dumplings carefully to boiling salted water in batches, stir gently once, and allow extra cooking time after they float. They are ready when the dough is tender and the filling is hot in the center.
