Polish Pierogi with Caramelized Onions

Ingredients

• 3 cup all-purpose flour
• 1 egg
• 1 cup sour cream
• pinch salt
• 2 lb russet potatoes (peeled, boiled, and mashed)
• 1 1/2 cup sharp cheddar cheese
• salt and pepper, to taste
• 4 tbsp butter
• 2 onions (thinly sliced)
• sour cream and chives, for serving

Steps

1. 1

   Make dough: mix flour, egg, sour cream, and salt until a smooth dough forms. Knead 2 minutes, wrap in plastic, and rest 30 minutes.

2. 2

   Make filling: fold cheddar cheese into hot mashed potatoes. Season with salt and pepper.

3. 3

   Roll dough thin on a floured surface. Cut 3-inch circles with a cutter. Place a tablespoon of filling on each, fold in half, and pinch edges firmly to seal.

4. 4

   Boil pierogi in salted water for 3-4 minutes until they float. Remove with a slotted spoon.

5. 5

   Melt butter in a large skillet and cook sliced onions over medium-low heat for 15 minutes until deeply caramelized. Add boiled pierogi and pan-fry until golden on both sides.

6. 6

   Serve topped with caramelized onions, a dollop of sour cream, and chives.
