Potato and Cheddar Pierogi

Step 1

In a large bowl, combine the flour, egg, water, and salt; knead for 5 minutes until a smooth dough forms. Cover and let rest for 20 minutes.

Step 2

Meanwhile, place the potatoes in a pot, cover with water, and boil for 15 minutes until fork-tender.

Step 3

Drain the potatoes and mash them with the cheddar and 2 tablespoons of the butter until smooth; let cool slightly.

Step 4

Roll out the dough on a floured surface to about 1/8 inch thick and cut into 3-inch rounds.

Step 5

Place a spoonful of the potato-cheddar filling in the center of each round, fold over, and pinch the edges to seal.

Step 6

Bring a large pot of salted water to a boil and cook the pierogi in batches for 3 to 4 minutes each, until they float to the top; remove with a slotted spoon.

Step 7

Melt the remaining butter in a large skillet over medium heat and sauté the onion for 6 minutes until golden.

Step 8

Add the boiled pierogi to the skillet and cook for 3 minutes per side until lightly browned.

Step 9

Serve warm, topped with sour cream.
