Full Recipe:

Ingredients

• 3 lbs Russet potatoes

• 1 yellow onion, finely diced

• 1 bunch scallions, finely sliced

• 2 cloves garlic, minced

• 1 cup all-purpose flour (sifted)

• ⅔ cup vegetable or canola oil

• 1 egg yolk (or vegan substitute such as aquafaba or oil spray)

• Salt to taste (start with 1-2 teaspoons)

Directions

1. Prepare potatoes: Preheat oven to 425°F. Poke potatoes with a fork 6 times each, lightly oil and season with salt. Bake for about 1 hour until tender. Peel while warm, then mash or mill through a food mill to a fine consistency.

2. Make dough: In a mixer bowl with dough hook, combine flour and salt. Slowly add water and oil while mixing until dough forms a rough ball. Knead on floured surface until smooth (~15 minutes). Rest dough covered for 30 minutes.

3. Make filling: Heat ½ cup oil in a skillet. Cook onions and scallion whites over medium heat until caramelized (~20 minutes). Add garlic and scallion greens, cook 1 minute. Mix into mashed potatoes, season with salt.

4. Assemble knishes: Preheat oven to 375°F. Divide dough into 8 balls. Roll each to a 7-inch circle. Brush with oil, add ~1 cup filling to center, fold dough up around filling leaving top exposed, overlap edges snugly.

5. Place knishes on lined baking sheet, brush with egg wash (yolk + water). Bake 30 minutes until golden.

The Dough: Simple Yet Essential

The dough for potato knishes is straightforward, made with all-purpose flour, water, oil, and a pinch of salt. While simple, the technique of kneading the dough until smooth and allowing it to rest is essential for developing elasticity, making it easier to roll out and fold around the filling.

Unlike rich, buttery pastries, this dough is intentionally light to balance the dense, hearty filling. The oil contributes to a tender crumb and ensures the crust crisps nicely in the oven. The dough’s texture and structure are key to holding the filling securely while baking, preventing sogginess and maintaining an appealing bite.

The Filling: Comfort in Every Bite

The filling is the star of the knish. Russet potatoes, baked until soft, are peeled while still warm and mashed or processed to a fine consistency. This smooth texture is critical for the filling to meld well and provide comfort with every bite.

Caramelized onions and scallions add sweetness, depth, and a subtle aromatic quality that complements the potatoes beautifully. Garlic adds a savory note, rounding out the flavors and providing a mild pungency. The filling is seasoned with salt to enhance the natural flavors, though it remains mild and versatile, perfect for pairing with many meals or enjoying on its own.

Assembly and Baking: Crafting the Perfect Knish

Assembling the knishes involves rolling the rested dough into thin circles and placing a generous scoop of filling in the center. Folding the dough around the filling with the top slightly open is traditional, showcasing the golden potato interior while ensuring the knish holds its shape during baking.

Brushing the exterior with egg yolk wash creates a glossy, golden crust that crisps nicely in the oven. Baking at 375°F for about 30 minutes results in a perfectly cooked knish with a sturdy, slightly crunchy shell and a moist, flavorful filling.

This hands-on process offers an enjoyable experience for home cooks, with a rewarding payoff in the finished product’s taste and texture.

Variations and Spice Enhancements

While the classic recipe is mild and comforting, knishes can be easily adapted for more adventurous palates. Adding spices such as smoked paprika, cumin, or chili flakes to the filling introduces warmth and complexity. Herbs like parsley, dill, or chives provide fresh brightness.

For those preferring a vegan option, egg yolk can be substituted with aquafaba or simply omitted, and oils can be chosen according to dietary preferences. The dough and filling also adapt well to alternative fillings such as sweet potatoes, mushrooms, or kale, offering endless creative possibilities.

Nutritional Highlights

Potato knishes offer a balanced nutritional profile. The main source of carbohydrates comes from potatoes and flour, providing energy and dietary fiber. The filling contributes a modest amount of protein, primarily from potatoes and scallions. The fat content is kept relatively low due to the moderate use of vegetable oil.
