Ingredients:
For the Dough:
- 3 cups (360g) all-purpose flour
- 1 large egg
- 1/2 cup (120ml) sour cream
- 1/2 cup (120ml) water
- 1/4 cup (60ml) unsalted butter, melted
- 1/2 teaspoon salt
For the Filling:
- 2 cups (about 500g) mashed potatoes (cooked and cooled)
- 1 small onion, finely chopped and sautéed until translucent
- 1/2 cup (120ml) sour cream
- Salt and pepper to taste
For Boiling and Cooking:
- Water for boiling
- Butter or oil for frying
- Sour cream or applesauce for serving (optional)
Instructions:
- In a large mixing bowl, combine the all-purpose flour and salt. Make a well in the center and add the egg, sour cream, water, and melted butter.
- Using a fork or your hands, gradually incorporate the wet ingredients into the flour mixture until a dough forms.
- Turn the dough out onto a lightly floured surface and knead it for about 5 minutes, or until smooth and elastic. Cover the dough with a clean kitchen towel and let it rest for 30 minutes.
- While the dough is resting, prepare the filling by combining the mashed potatoes, sautéed onions, sour cream, salt, and pepper in a mixing bowl. Mix until well combined.
- After the dough has rested, roll it out on a lightly floured surface to about 1/8 inch thickness. Use a round cookie cutter or drinking glass to cut out circles of dough.
- Place a small spoonful of the potato filling in the center of each dough circle. Fold the dough over the filling to form a half-moon shape, and press the edges together to seal. You can crimp the edges with a fork for decoration, if desired.
- Repeat the process with the remaining dough and filling until all the pierogi are assembled.
- Bring a large pot of salted water to a boil. Carefully drop the pierogi into the boiling water, a few at a time, and cook them for 3-4 minutes, or until they float to the surface.
- Remove the cooked pierogi from the water using a slotted spoon and transfer them to a plate lined with paper towels to drain.
- Heat butter or oil in a skillet over medium heat. Once hot, add the boiled pierogi in batches and fry them until golden brown and crispy on both sides, about 2-3 minutes per side.
- Remove the fried pierogi from the skillet and drain them on paper towels.
- Serve the Polish pierogi hot, with sour cream or applesauce on the side for dipping, if desired.
- Enjoy your homemade Grandma’s Polish Pierogi as a comforting and delicious meal or snack!
