Ingredients:
- 3 cups (375g) all-purpose flour, plus more for dusting
- 1 teaspoon (5g) salt
- 1 large egg
- 1 cup (240ml) warm water
- 2 tablespoons (30ml) melted unsalted butter
- 2 pounds (900g) Yukon Gold potatoes, peeled and quartered
- 1/2 cup (120ml) milk
- 4 tablespoons (57g) unsalted butter
- 1 large yellow onion, finely diced
- 8 ounces (225g) farmers cheese (or dry curd cottage cheese), crumbled
- 4 ounces (115g) sharp cheddar cheese, grated (optional, but adds flavour)
- Salt and freshly ground black pepper to taste
- 6 tablespoons (85g) unsalted butter, divided
- Optional toppings: sour cream, caramelized onions, fried bacon bits
Instructions:
- Combine flour and salt in a large bowl. Create a well in the center and add the egg, warm water, and melted butter. Gradually incorporate the flour until a shaggy dough forms. Knead for 5-7 minutes until smooth and elastic. Wrap in plastic wrap and let rest at room temperature for at least 30 minutes.
- Boil potatoes until tender. Drain well and return to the pot. Mash the potatoes with milk and butter until smooth and creamy. Season with salt and pepper.
- Melt 2 tablespoons butter in a skillet over medium heat. Add the diced onion and sauté until softened and lightly golden.
- In a large bowl, combine the mashed potatoes, sautéed onions, farmer's cheese, cheddar cheese (if using), salt, and pepper. Mix well until thoroughly combined. Taste and adjust seasonings as needed.
- On a lightly floured surface, roll out the dough to about 1/8 inch thickness. Use a cookie cutter or glass to cut out circles. Place a spoonful of filling in the center of each circle.
- Fold the dough over the filling to form a half-moon shape. Pinch the edges tightly to seal, ensuring no air pockets remain.
- Bring a large pot of salted water to a boil. Gently drop the pierogi into the boiling water, a few at a time, being careful not to overcrowd the pot. Cook until they float to the surface plus an additional 2-3 minutes.
- Melt the remaining butter in a large skillet over medium heat. Carefully remove the boiled pierogi from the water with a slotted spoon and place them in the skillet. Cook until golden brown and crispy on both sides, about 3-4 minutes per side.
- Serve immediately with sour cream, caramelized onions, and/or fried bacon bits, if desired.
