Description
Classic Jewish Potato Knishes with a golden, flaky crust and a creamy mashed potato and caramelized onion filling. These savory pastries are comforting, satisfying, and perfect as a snack, side dish, or appetizer.
Ingredients
2½ cups all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
½ cup vegetable oil
2 large eggs (one for dough, one for egg wash)
½ cup water
2 pounds Yukon Gold potatoes, peeled and cubed
1 large yellow onion, finely chopped
2 tablespoons olive oil (for sautéing onions)
½ teaspoon black pepper
½ teaspoon additional salt
Instructions
- Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.
- In a large bowl, whisk together flour, baking powder, and salt.
- In another bowl, whisk one egg with vegetable oil and water. Combine wet and dry ingredients to form a smooth dough.
- Knead lightly, cover, and let rest for 30 minutes.
- Meanwhile, boil potatoes in salted water for about 15 minutes until tender. Drain and mash until smooth.
- Sauté the finely chopped onion in olive oil over medium heat until golden and fragrant. Mix onions into the mashed potatoes along with salt and pepper.
- Divide dough in half and roll each portion into a rectangle about ¼ inch thick.
- Spread half the potato filling along one long edge, leaving space at the ends. Roll into a log and pinch the ends to seal. Repeat with the remaining dough and filling.
- Slice each log into 3-inch pieces, pinch sides to seal, and place seam-side down on the prepared baking sheet.
- Beat the remaining egg and brush over each knish.
- Bake for 35–40 minutes until golden brown and lightly puffed.
- Cool slightly and serve warm with mustard, sour cream, or on their own.
Notes
Add mushrooms, spinach, or cheese for a flavorful variation.
Brush with sesame or poppy seeds for an elegant finish.
Make mini knishes for parties or appetizers—they bake faster.
Freeze baked or unbaked knishes for long-term storage.
For vegan knishes, use plant-based egg substitute or brush with non-dairy milk.
