These potato vareniki are a simple, classic dish that never fails to bring comfort. The dough is tender, the filling is buttery and smooth, and the caramelized onions on top make every bite special. I love serving them warm with sour cream.

Why This Recipe Works

I make these vareniki whenever I want something cozy and homemade that feels like a true comfort meal. Here’s what makes them stand out:

  • Soft, Tender Dough: The sour cream in the dough keeps it smooth, elastic, and easy to roll. It’s the same kind of soft texture I love in my No Yeast Piroshki.
  • Creamy Potato Filling: The filling is buttery, fluffy, and perfectly seasoned. It’s simple, but it tastes like home in every bite.
  • Golden Buttered Onions: Slow-cooked onions in butter add a deep, savory flavor that takes these dumplings to the next level. They bring the same cozy warmth you’ll find in a bowl of Soup with Pelimeni.
  • Perfect for Sharing: This recipe makes about 60 vareniki, which means there’s plenty to go around. They’re great for family dinners or freezing for later.
  • Classic Comfort Food: These dumplings are the kind of meal that never goes out of style – simple ingredients, homemade flavor, and a touch of love in every bite.

Ingredients

  • All-Purpose Flour – The base of the dough that gives structure and a soft, chewy texture. Keep extra on hand for rolling to prevent sticking.
  • Sour Cream – Adds richness and keeps the dough tender and easy to roll. Plain Greek yogurt can be used as a substitute.
  • Iced Water – Helps keep the dough cool and smooth while mixing, preventing it from becoming tough.
  • Egg – Binds the dough together and adds elasticity for easier shaping.
  • Potatoes – The main filling ingredient, creating a creamy and comforting center. Russet or Yukon Gold potatoes work best.
  • Milk – Makes the mashed potato filling smooth and creamy. Warm milk blends best with the potatoes.
  • Butter – Used in both the filling and the topping for richness and flavor. Unsalted butter is ideal so you can control the salt level.
  • White Onion – Slowly caramelized in butter for a sweet, savory topping that pairs perfectly with the dumplings.

Instructions

  1. Make the Filling: Peel and boil potatoes until soft. Drain well. Mash with milk, butter, salt, and pepper until smooth. Set aside to cool completely.
  2. Make the Dough: In a bowl, whisk together egg, sour cream, iced water, and salt. Gradually add flour until a soft, non-sticky dough forms. Cover with plastic wrap and rest for 20 minutes.

  1. Shape the Vareniki: Divide dough into portions. Roll each into a log and cut into small pieces. Roll each piece into a thin circle. Alternatively, roll the dough into a sheet and cut circles using a cup or glass.
  2. Fill and Seal: Spoon a small amount of potato filling into the center of each circle. Fold in half and pinch edges tightly to seal. Avoid overfilling or rolling too thin. You can use this mold and pasta making set for it that can also be used for ravioli.

  1. Cook the Vareniki: Bring salted water to a boil. Add vareniki in batches. Once they float to the top, cook 2–3 minutes longer. Remove with a slotted spoon and drain well.
  2. Make the Butter Caramelized Onions: Melt butter in a pan over low heat. Add chopped onion and a pinch of salt. Cook slowly, stirring occasionally, until onions turn soft and golden.
  3. Serve: Toss hot vareniki in the buttered onions. Serve warm with a generous spoon of sour cream.

Substitutions & Variations

Here are some of my favorite substitutions and variations:

  • Filling Options: I usually stick with mashed potatoes, but you can mix in sautéed mushrooms, cottage cheese, or caramelized onions for extra flavor. Sweet fillings like cherries or blueberries also make a great dessert version.
  • Dough Choices: I like using sour cream for tenderness, but plain yogurt or kefir works too. Just keep the dough soft and easy to roll.
  • Topping Ideas: Try topping with crispy bacon bits, fresh herbs, or a drizzle of browned butter instead of caramelized onions. A spoonful of sour cream or melted butter always works too.

FAQs

Can I use a different filling?

Yes. You can replace the potato filling with cottage cheese, mushrooms, or even fruit like cherries for a sweet version. Just make sure the filling isn’t too wet so the dough seals properly.

What’s the best way to shape the vareniki?

You can roll the dough into a sheet and cut circles with a cup or roll small pieces into rounds by hand. Both methods work well as long as the dough isn’t too thin.

Can I make the dough ahead of time?

You can prepare the dough a few hours in advance and keep it wrapped in plastic in the fridge. Let it come to room temperature before rolling so it’s easier to work with.

Do I need to boil all the vareniki at once?

No. It’s best to cook them in batches so they don’t stick together. Once they float to the top, give them a couple more minutes before removing.

How long does it keep?

Store cooked vareniki in an airtight container in the fridge for up to 3 days. To reheat, boil briefly or pan-fry in butter until warm. You can also freeze uncooked vareniki on a tray, then transfer to a bag and cook straight from frozen when ready to serve.

These potato vareniki are a simple, classic dish that never fails to bring comfort. The dough is tender, the filling is buttery and smooth, and the caramelized onions on top make every bite special. I love serving them warm with sour cream.
Servings 60 vareniki

Ingredients
  

For the Dough:

  • 3 cups all-purpose flour plus more for rolling
  • 1/3 cup sour cream
  • 3/4 cup iced water
  • 1 egg
  • 1 tsp salt

For the Potato Filling:

  • 3 potatoes
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 cup milk
  • 3 tbsp butter

For the Butter Caramelized Onions (Topping):

  • 4 tbsp butter
  • 1/2 large white onion chopped
  • Pinch of salt

Instructions
 

Make the Filling:

  • Peel and boil the potatoes until soft.
  • Drain well.
  • Using a hand mixer, combine the potatoes, milk, butter, salt, and pepper.
  • Mix until smooth and creamy.
  • Set aside to cool completely before filling.

Make the Dough:

  • In a large bowl, whisk together the egg, sour cream, iced water, and salt.
  • Gradually add the flour, mixing until a soft dough forms that doesn’t stick to your hands.
  • Cover the dough with plastic wrap and let it rest for 20 minutes.

Shape the Vareniki:

  • Method 1: Divide the dough into 4 pieces. Take one piece and divide it in half. Roll into a log, cut into small pieces, and roll each piece into a circle.
  • Method 2: Roll the dough into a sheet and cut circles using a cup or glass.

Fill and Seal:

  • Place about 1 teaspoon of potato filling in the center of each dough circle.
  • Fold in half and pinch the edges tightly to seal. You can use this mold and pasta making set for it that can also be used for ravioli.

Cook the Vareniki:

  • Bring a large pot of salted water to a boil.
  • Add the vareniki in batches to avoid overcrowding.
  • Once they float to the top, cook for an additional 2–3 minutes.
  • Remove with a slotted spoon and drain well.

Make the Butter Caramelized Onions:

  • Melt the butter in a pan over low heat.
  • Add the chopped onion and a pinch of salt.
  • Cook slowly, stirring occasionally, until the onions turn soft and golden.

To Serve:

  • Toss the hot vareniki in the butter and caramelized onions. Serve warm with a generous side of sour cream.

Notes

  • Don’t overfill or roll the dough too thin, as the vareniki may open or tear while boiling. A small spoonful of filling is enough to keep the edges sealed during boiling.
  • Use cold ingredients for the dough. Iced water and chilled sour cream help keep the dough soft and easy to roll.
  • Rest the dough before rolling. A short 20-minute rest relaxes the gluten, making shaping smoother and preventing shrinkage.
  • Mash the potatoes while hot. They blend more evenly with butter and milk, giving the filling a creamy texture.
  • Let the filling cool completely. Warm filling can make the dough sticky and harder to seal.
  • The sour cream makes the dough extra tender and easy to work with.
  • Boil in batches. Too many at once can lower the water temperature and cause them to stick together.
  • Stir gently while cooking. This keeps the dumplings from settling at the bottom and tearing.
  • Freeze before cooking. Arrange raw vareniki on a tray, freeze until firm, then store in a bag. Cook straight from frozen when needed.
  • Finish with buttered onions. Tossing them in golden caramelized onions right before serving adds rich flavor and a beautiful shine.
