Description

Potato Knishes are a classic Jewish pastry made with a flaky dough and filled with a comforting mixture of mashed potatoes and caramelized onions. These savory bites are perfect as a snack, appetizer, or side dish.


Ingredients

Scale
  • 2 cups all-purpose flour
  • 1/2 tsp salt
  • 1/2 tsp baking powder
  • 1 large egg
  • 1/4 cup vegetable oil
  • 1/2 cup warm water
  • 2 cups mashed potatoes
  • 1 large onion, finely chopped
  • 2 tbsp butter or oil (for sautéing)
  • Salt and pepper to taste
  • 1 egg (for egg wash)

Instructions

  1. In a large bowl, mix flour, salt, and baking powder. In another bowl, whisk egg, oil, and warm water. Combine wet and dry ingredients to form a smooth dough. Cover and let rest for 30 minutes.
  2. Meanwhile, sauté chopped onion in butter or oil over medium heat until golden and caramelized, about 10–15 minutes. Mix into the mashed potatoes and season with salt and pepper.
  3. Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper.
  4. Roll out the dough on a lightly floured surface into a thin rectangle. Cut into squares (about 4×4 inches).
  5. Place a spoonful of filling in the center of each square. Fold edges over to seal, forming a round or rectangular shape.
  6. Place knishes seam-side down on the baking sheet. Brush tops with beaten egg.
  7. Bake for 30–35 minutes until golden brown. Serve warm or at room temperature.

Notes

  • You can substitute the filling with kasha, sweet potato, or spinach for variation.
  • Kneading the dough well ensures a soft, pliable texture.
  • Knishes can be made ahead and frozen before baking.
