These are awesome! Straight out of Brooklyn is the Coney knish with a flaky crust and filled with potato, fried onion, and yes, hot dogs. These tasty treats are very popular in Brooklyn kosher deli and take out places. Sometimes I'll cut each one into 3 or 4 pieces before baking and serve them as a hot appetizer. Serve with a side of spicy brown mustard for dipping.

  • Preheat oven to 400 degrees F (200 degrees C). Grease a baking sheet.

  • Heat oil in a skillet over medium heat; saute onions until golden brown, 10 to 15 minutes. Mix potatoes, salt, and pepper into onions. Remove skillet from heat and cool.

  • Roll each puff pastry sheet onto a work surface. Cut each sheet into 4 squares. Spread about 1/4 cup potato mixture onto each square in a strip down the middle; top with a hot dog. Cover each hot dog with about 1/4 cup more potato mixture. Roll puff pastry around hot dog and filling; place, seam side-down, on the prepared baking sheet. Brush puff pastry with egg.

  • Bake in the preheated oven until golden brown, 10 to 15 minutes.

Amazing!!!! Delicious!!!! I followed the recipe only changing using cocktail hotdogs and making themappetizer size. Honestly my hubby and I were worried that the potatoes would be dry no way they were so creamy. Our family couldn t get enough and wanted to know when we were gonna make them again. Easy to prepare wouldn t change one step Read More

I will make them again, but I will roll them differently. The dough came out a bit hard. I blame the altitude. Read More

First these were DELICIOUS. I will definitely be making them again. Second there has to be errors in the quantities listed and the cooking time. 1) I used 2.5 medium onions and 6 large potatoes and there was enough filling for twice the number of knishes. 2) The squares from the puff pastries were too small to wrap around a hot dog with 1/2 cup of potatoes. 3) The dough was still soft after 15 minutes of cooking. I lost track of how many times I added 10 minutes to the timer until the pastries were crisp golden brown and flaky. 4) It took us (my son and I) two hours from start to finish. But like I said they were fantastic and everybody loved them. Read More
