Knish Recipe With Root Vegetable Mash

SUPER EASY POTATO KNISHES

Steps:

• Heat oven to 400F/204C.
• MAKE POTATO MIXTURE: To fry onions, heat oil on medium heat and sauté onions for 5-6 minutes just until slightly brown. Combine mashed potatoes and caramelized onions in a medium bowl with a fork. Season with salt and pepper - or 2 tablespoons of dry onion soup mix - to taste. You can omit the salt and pepper if you are using leftover mashed potatoes that are already seasoned.
• MAKE KNISHES: You will make two rolls of knishes from each sheet of puff pastry. On a lightly floured surface, unroll one sheet of puff pastry dough. It should be about 1/4 inch/0.63cm thick or less. Stretch out or roll dough a bit if necessary. Spread potato filling to resemble a log - about 2 inches/5cm thick - along one side of the rolled dough. Fold dough over the potato about 1 1/2 times in a jelly-roll fashion, making a log/roll. Cut away remaining dough with a sharp knife for the next roll. Tuck ends and pinch seams together well (to ensure filling doesn't seep out). Repeat with other half of dough on the same sheet of dough. Then do the same with the second sheet of dough. If you have extra dough and potato mixture left over, make a 5th roll.
• BAKE: Place rolls on a large baking sheet lined with parchment paper, seam side down. Brush egg wash on rolls which will create a glazed golden look (optional). Bake for 25-30 minutes to a golden brown flaky pastry. If any potato mixture seeps out, tuck it back into the knish roll with a knife.
• TO SERVE: Cut rolls of finished knishes into 2 inch/5 cm pieces on the diagonal and serve. To make ahead (recommended!) see Note 2.

KNISH RECIPE WITH ROOT VEGETABLE MASH

Steps:

• Heat oven to 375F.
• MAKE ROOT VEGETABLE FILLING: (can be done 2-3 days ahead)°Prep and boil: Cut veggies into roughly the same size - about 1 - 1 1/2 inches. If using carrots, slice them thinner as they take longer to cook. Place in pot and add water to cover by 1 inch. Add 2 tsp salt. Bring to boil. Lower to medium and gently boil for 15-18 minutes or until soft and easily pierced with a fork. Drain vegetables in a colander and return to the pot. °Mash: On medium heat, shake cooked vegetables to dry them out for 1 minute. Add green onions, butter and milk/cream. Mash with a fork to get the consistency you like. Do not use a food processor or immersion blender to mash veggies. Taste and add salt and pepper as needed. Set aside or store in fridge until ready to make knishes.
• ASSEMBLE KNISHES: On a lightly floured cutting board, unroll one sheet of dough. It should be about 1/8-1/4 inch thick. Stretch it out a bit to make a rectangle. Spread a log of vegetable mash mixture along the longer side of the rectangle - about 2 inches thick. Roll dough over the vegetable mixture about 1 and 1/2 times, making a log/roll. Cut away rest of dough for the next roll. Pinch seams together well. Repeat with other half of dough on that sheet. Then do the same with the second sheet of dough. You will have 4 logs/rolls in total.
• BAKE: Place filled knish rolls - 2 inches apart - on a large parchment-lined pan, seam side down. Brush egg wash on rolls to create a glazed golden look. Bake for 35-40 minutes until golden brown and flaky. Cut rolls into 2 inch pieces on the diagonal and serve. Or see Note 2 for make ahead options.

Sprinkle the dough with flour and cover with parchment paper. Let the dough rest for 15 minutes. Using your hands, spread the dough out very thin. Spread 1/4 of the filling onto one third of the dough, leaving a one inch border. Holding the parchment paper, roll up the dough like a jelly roll, brushing oil across the top a couple of times as you roll. Using the side of your hand like a knife, divided the roll into 2-inch knishes. pinch the open ends shut. Repeat procedure with remaining balls and dough. Place the knishes, flat side down, 2 inches apart, on a greased baking sheet. The knishes will need to be baked in batches. Brush the knishes with the egg wash.
