POTATO KNISH hold a special place in Jewish cuisine, serving as a beloved classic that has stood the test of time. These delectable treats, with their origins deeply rooted in Jewish culture, are much more than just a savory snack - they are a symbol of tradition and comfort. The history of potato knishes traces back to Eastern Europe, where they were initially crafted as a hearty and filling dish for families to enjoy. Over time, the popularity of potato knishes has spread far and wide, becoming a staple in Jewish households and beyond. Today, we celebrate the rich heritage and delicious flavors of potato knishes, honoring the culinary legacy they carry with each bite. 

These delicious treats feature a savory filling of seasoned mashed potatoes encased in a flaky pastry shell. Whether you're a fan of traditional Jewish dishes or looking to try something new, my Potato Knish recipe is sure to satisfy your taste buds.

You can prepare the dough and the potato mixture from scratch by grating the onion and potatoes, which we have done from time to time, or you can prepare this quick and easy recipe when you have leftover mashed potatoes.

EQUIPMENT: measuring cups and spoons, mixing bowls, large stainless steel baking sheet with rack. 


  • 1½ cups mashed potatoes.
  • 1 medium onion chopped and fried in butter or 1 tsp onion powder.
  • 1 tsp Schmaltz* or chicken base
  • Sprinkle or apple cider vinegar.
  • 1 egg yolk
  • 1 egg while beaten well.
  • 8 to 10 oz. Puff pastry dough, crescent roll dough, or filo dough


Preheat the oven to 375°F (190°C).

In a large stainless steel mixing bowl combine the mashed potatoes, onion, Schmaltz, apple cider vinegar, and egg yolk. Mix well. Adjust the flavor as needed.

Divide the dough into 4 equal parts. Roll each part out into a thin rectangle. Place a quarter of the potato mixture onto each rectangle of dough, leaving a small border around the edges. Roll the dough up tightly around the potato mixture, tucking in the edges as you go.

Place the knishes on a baking sheet rack or baking sheet lined with parchment paper. Brush them with beaten egg whites. Bake for 30-35 minutes, until golden brown.


When it comes to serving knish, several fantastic side dishes can complement its flavors and make your meal even more satisfying.

Some popular choices to serve with knish include a crisp and fresh side salad with a tangy vinaigrette, roasted or grilled vegetables like zucchini, bell peppers, or carrots for added texture and flavor, or a creamy coleslaw for a classic pairing. For a heartier option, consider serving knish with a warm bowl of soup such as tomato basil or butternut squash, or some protein-rich dishes like grilled chicken skewers or baked salmon. Don't forget to offer some condiments like sour cream, mustard, or pickles on the side for an extra burst of flavor. With these delectable side dishes, your knish meal is sure to be a hit with friends and family alike. Enjoy your delicious homemade potato knish!


Knishes can be filled with a variety of savory or sweet fillings. Some popular savory options include sautéed onions, mushrooms, kasha buckwheat groats, and even ground beef or chicken. For a sweet twist, try filling your knish with fruits like apples, cherries, or blueberries, or go for a classic sweet cheese filling. The possibilities are endless! So, next time you're looking for a delicious and comforting snack, consider making a batch of knishes with your favorite filling.

*Schmaltz is a traditional Jewish condiment made by rendering chicken or goose fat. It is commonly used in Jewish cuisine to add flavor and richness to dishes such as matzo balls, chopped liver, and challah bread. Schmaltz has a distinctive savory taste and a silky texture that can enhance the flavor of any dish. Try adding a dollop of schmaltz to your next soup or stew for a delicious and authentic Jewish flavor!
