Vareniki with Potato and Cheese
Soft dumplings filled with mashed potato and farmer's cheese, boiled and finished with caramelized onions and sour cream.
About This Recipe
Vareniki are closely related to pelmeni but larger, most often filled with something soft and savory like mashed potato mixed with farmer's cheese, rather than raw meat. The dough is a touch more tender, sometimes enriched with a spoonful of sour cream or an egg, and rolled slightly thicker to hold a larger filling without tearing. The potato filling is mashed smooth with butter and mixed with farmer's cheese and a little sauteed onion, then sealed into half-moon shapes and boiled until they float. What finishes the dish, and what most home cooks consider non-negotiable, is a generous topping of onions cooked low and slow in butter until deeply caramelized and sweet. Vareniki are shared across Russia, Ukraine and Poland as ultimate comfort food, the kind of labor-intensive dish grandmothers make in huge batches for the whole family to freeze and eat over weeks.

- 3 cupsall-purpose flour(plus more for rolling)
- 1egg

Instructions
- 1
Make the dough
Mix flour, egg, water, sour cream and salt into a smooth, elastic dough. Rest covered for 30 minutes.
- 2
Boil the potatoes
Boil the potatoes until fork-tender, about 15 minutes. Drain and mash with 3 tbsp butter.
- 3
Make the filling
Saute the diced onion in a little butter until soft, then mix into the mashed potato along with farmer's cheese and salt.
- 4
Roll and cut
Roll the dough thin, about 1/8 inch, and cut into 3-inch rounds.
- 5
Fill and seal
Place a spoonful of filling in each round, fold into a half-moon and pinch the edges tightly closed.
Crimp the edges with your fingers rather than just pressing flat — a proper crimp is what keeps the seam from opening in boiling water.
- 6
Make the onion topping
Cook the sliced onion in remaining butter over low heat for 20-25 minutes, stirring occasionally, until deeply caramelized.
- 7
Boil the vareniki
Boil in batches in salted water for 4-5 minutes until they float and the dough is tender.

Serve
Toss the boiled vareniki with the caramelized onions and serve with sour cream.

Pro Tips
- →
Cook the topping onions low and slow for the full 20-25 minutes — rushed onions never develop the deep sweetness vareniki are known for.
- →
Crimp the dumpling edges firmly with your fingers rather than a fork; a hand-crimped seal holds up better in boiling water.
- →
Mash the potato filling completely smooth before adding cheese, or the texture turns lumpy inside the dumpling.
Variations
- •
Make a sweet version filled with sweetened farmer's cheese or fresh cherries, a common dessert variation.
- •
Add sauerkraut to the potato filling for a tangier, more traditional Ukrainian-style vareniki.
- •
Fry boiled vareniki briefly in butter for extra crispness on the outside.
Storage
Freeze uncooked vareniki on a tray before bagging; they keep up to 3 months and boil straight from frozen with 1-2 extra minutes. Cooked vareniki keep refrigerated 2 days.
History & Origin
Vareniki are considered a Ukrainian dish that spread widely into Russian and Polish home cooking, with roots that likely trace to Turkic dumpling traditions that reached Eastern Europe through trade and migration centuries ago.
Frequently Asked Questions
Can I use instant mashed potatoes for the filling?
Fresh boiled and mashed potato gives a much better texture; instant potato flakes tend to make the filling gummy once boiled inside the dough.
What if I don't have farmer's cheese?
Well-drained cottage cheese, pulsed briefly in a food processor to break up the curds, works as a close substitute.
Why do my vareniki keep opening while boiling?
The edges likely weren't sealed tightly enough — pinch and crimp firmly, and make sure there's no filling or flour dust on the edges preventing a good seal.
