A golden, flaky pastry stuffed with savory filling, the knish is beloved by generations and continues to be a symbol of Jewish-American comfort food.

Whether eaten hot or cold, from a street cart or homemade, a New York knish delivers heartwarming flavor in every bite.
Understanding the Classic New York Knish
The knish is more than just a snack it’s a reflection of immigrant history, particularly of Ashkenazi Jewish communities who brought their recipes to the United States from Eastern Europe. In New York, the knish became popular in delis, bakeries, and street corners, often served with mustard or enjoyed alongside a pickle or hot dog. The traditional version is a round or square pastry with a thick, chewy dough encasing a dense filling, typically made of mashed potatoes, onions, and seasonings.
Common Knish Fillings
- Mashed potatoes with caramelized onions
- Ground beef or kasha (buckwheat groats)
- Spinach and cheese
- Sauerkraut or cabbage
While modern variations exist, the classic potato knish remains the most iconic and widely loved.
Ingredients for a Traditional Potato Knish
To create a traditional New York knish at home, you’ll need simple pantry staples. The dough is tender and slightly chewy, and the filling should be smooth, flavorful, and satisfying. Here’s a breakdown of what you’ll need:
For the Dough:
- 2 cups all-purpose flour
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
- 1 large egg
- 1/3 cup vegetable oil
- 1/3 cup warm water
For the Potato Filling:
- 2 pounds russet potatoes, peeled and cubed
- 1 large onion, finely chopped
- 2 tablespoons vegetable oil or schmaltz (chicken fat)
- Salt and pepper to taste
- Optional: a pinch of garlic powder or paprika
Step-by-Step Preparation
1. Make the Dough
In a mixing bowl, combine flour, salt, and baking powder. In a separate bowl, whisk together the egg, oil, and warm water. Pour the wet mixture into the dry ingredients and stir until a dough forms. Knead gently until the dough becomes smooth and elastic, about 3-5 minutes. Cover the dough with a damp towel and let it rest for at least 30 minutes. Resting helps make the dough easier to roll and work with later.
2. Prepare the Potato Filling
While the dough rests, place the peeled and cubed potatoes in a large pot of salted water. Bring to a boil and cook until the potatoes are tender usually around 15-20 minutes. Drain and mash until smooth.
Meanwhile, heat the oil or schmaltz in a pan and sauté the chopped onion until golden brown and caramelized. This step adds a sweet, savory depth to the filling. Mix the onions into the mashed potatoes and season generously with salt, pepper, and any desired spices. Set aside to cool slightly before filling the knishes.
3. Assemble the Knishes
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper. Divide the rested dough into equal portions typically about 6 to 8 pieces, depending on how large you want your knishes.
On a lightly floured surface, roll out each piece of dough into a thin circle or rectangle. Place a scoop of filling in the center and fold the edges of the dough around it, forming a puck-shaped knish. Pinch the dough closed and place seam-side down on the baking sheet. You can gently flatten the top for a more traditional look.
4. Bake Until Golden
Brush the tops of the knishes with a little oil or an egg wash for a glossy finish. Bake in the preheated oven for 35-45 minutes, or until the dough is golden brown and slightly crisp on the edges. Let the knishes cool for a few minutes before serving, as the filling will be hot.
How to Serve a Knish
Traditional New York knishes are hearty enough to be a standalone snack, but they also pair well with a variety of side dishes and condiments. Here are a few serving suggestions to make the most of your homemade knish experience:
Popular Serving Ideas:
- With spicy brown mustard for dipping
- Alongside a kosher dill pickle
- With a side of coleslaw or sauerkraut
- As part of a deli-style platter with smoked meats
Knishes can be served warm straight from the oven or reheated later. Some even enjoy them at room temperature as a portable snack or lunchbox item.
Tips for Perfecting the Recipe
Making knishes from scratch can be a fun and rewarding kitchen project. While the ingredients are simple, technique and timing make all the difference. Here are some helpful tips to ensure your knishes come out just right:
- Let the dough rest adequately so it’s easier to handle and roll thinly.
- Don’t overfill the knish too much filling can cause it to burst open while baking.
- Use well-mashed potatoes for a smooth texture.
- Caramelize the onions slowly to enhance flavor.
- Seal the dough edges tightly to prevent leaks.
If you want to save time, the dough and filling can be made a day in advance and stored in the refrigerator until ready to assemble.
