Potato Knishes

Warm, golden, and irresistibly flaky, Potato Knishes are the kind of comfort food that instantly feels like home. Imagine biting into a delicate pastry that gives way to a creamy, seasoned potato filling that’s both hearty and satisfying. The aroma alone, buttery and slightly toasty, wraps you in nostalgia. Whether enjoyed as a snack, appetizer, or side dish, each knish carries a story of tradition and love baked right into its folds.

Behind the Recipe

This recipe takes inspiration from the bustling streets of New York’s Lower East Side, where Jewish immigrants brought their treasured knish recipes from Eastern Europe. These humble pockets of dough were once sold from pushcarts, warm from the oven, filling the air with the comforting scent of mashed potatoes and onions. I remember my first knish from a tiny bakery tucked between two delis—it was love at first bite, crisp outside and cloud-soft inside.

Recipe Origin or Trivia

Knishes originated in Eastern Europe, particularly among Ashkenazi Jewish communities in countries like Poland and Ukraine. Traditionally filled with mashed potatoes, kasha, or cheese, they became a symbol of comfort and sustenance. When immigrants brought them to America, the knish quickly found fame as an iconic street food in New York. Today, they’re celebrated worldwide as a taste of old-world charm with a modern twist.

Instructions for Making Potato Knishes

Now that everything’s ready, let’s get cooking! Here’s how to make them step by step:

1. Preheat Your Equipment:
   Set your oven to 375°F (190°C) and line a baking sheet with parchment paper.
2. Combine Ingredients:
   In a large bowl, mix flour, baking powder, salt, oil, one egg, and water until a dough forms. Knead gently until smooth, then let rest for 30 minutes.
3. Prepare Your Cooking Vessel:
   In a skillet, melt butter and sauté chopped onions until golden and fragrant. Mix into mashed potatoes with salt and pepper to taste.
4. Assemble the Dish:
   Roll the rested dough into a thin rectangle. Spread the potato mixture evenly across the bottom third, then roll up tightly like a jelly roll. Cut into sections about 2 inches wide.
5. Cook to Perfection:
   Place knishes seam-side down on the prepared baking sheet. Brush tops with beaten egg. Bake for 25–30 minutes until golden brown.
6. Finishing Touches:
   Let them cool slightly before serving. The crust should be crisp, and the filling piping hot.
7. Serve and Enjoy:
   Enjoy warm, ideally with a dollop of sour cream or a side of mustard for that authentic touch.

Texture & Flavor Secrets

The magic of a great knish lies in contrast—the crust should shatter slightly when bitten, revealing a soft, creamy interior bursting with buttery potatoes and sweet onions. The flavors develop as the knishes bake, creating a symphony of toasty pastry and savory filling that lingers beautifully.

Cooking Tips & Tricks

• Chill your filling before assembling to make shaping easier.

What to Avoid
