Potato Knish

The recipe of knish is used in order to prepare a flavorful meal that can be eaten by vegetarians as well.

You can add any sauce to the crispy knishes as you eat them but there is a tangy mustard flavor that is incorporated into the recipe.

Preparation Time: 45 minutes (including the boiling time for the potatoes)

Cooking Time: about 38 minutes

Servings: 5


  • 1/2 cup extra virgin olive oil (or you can substitute for safflower or canola oil)
  • 3 cups of all purpose flour
  • egg replacer - for the measure of 2 whole eggs - you will use 1 egg equivalent in the dough and the remainder in the filling (or you can use 2 eggs)
  • 3 tbsp of granulated sugar
  • 1/2 cup of water
  • 1 tsp of baking powder
  • 1/4 tsp of baking soda

  • 1/4 cup grated carrot (sautéed for 5 minutes in olive oil)
  • 6 Yukon gold potatoes
  • 1/2 tsp salt
  • 1/4 tsp of pepper
  • 1 tsp dry mustard
  • 1 cup chopped onions (slightly cooked in olive oil with just a bit of sugar)
  • 1/4 cup deli mustard mixed with 1 teaspoon of diced jalapenos (browned in a teaspoon of olive oil)


  1. Add the first 7 ingredients (reserve 1/3 cup flour) to a large mixing bowl and combine them together. This will create a sticky dough but you can fix it by using some of your reserved flour and adding it to the bowl. Remember to use the equivalent of one whole egg (or use 1 egg).

  2. Once you have soft, silky dough you should divide it into 10 to 12 equal portions.

  3. Roll each of these into a small ball and then roll out flat with a floured rolling pin.

  4. Use a butter knife to create 10 to 12 small rectangles of dough. 

  5. Wash, peel, quarter and boil the potatoes. Cook just until tender to the fork.

  6. Mash the potatoes and then combine with: salt, pepper, dry mustard, egg replacer that equals one whole egg (or egg), grated carrot and caramelized chopped onions.

  7. Spread a small amount of the spicy mustard mixture over the top each pastry rectangle.

  8. Add a spoonful of the potato filling to each of these pastry rectangles.

  9. Fold over the edges and use a fork to crimp the edges.

  10. Place all of the potato knish onto a cookie sheet and bake in an oven at 350º F (177º C) for about 38 minutes. They will be golden brown in color when they are done.


- Serve a small dish of some plain mustard with them. You can spoon the mustard into the interior of the potato knishes as you eat them.

- To create additional crispness you may wish to spread a little egg replacer or (egg) over the exterior of each one prior to placing them in the oven.
