Savory Potato Rolls (A/K/A Potato Knishes the Easy Way)

The scent of warm potatoes and sauteed onions still vividly brings me back to my grandmother’s bustling kitchen. She didn’t measure anything, just knew exactly how much of each ingredient to add. These savory potato rolls, or as she playfully called them, “knishes the easy way,” were always a family favorite. The buttery puff pastry embracing the savory potato filling was the perfect comforting treat on a chilly evening. I’ve adapted her recipe over the years, streamlining the process while staying true to her original delicious flavors.

• Total Time: 50 minutes
• Servings: 4 rolls (approx. 32 pieces)
• Yield: 32 pieces
• Dietary Type: Vegetarian

Ingredients

• 6 medium potatoes, parboiled in their skins, peeled, and mashed
• 2 medium onions, minced
• 4 tablespoons oil (vegetable, canola, or olive oil work well)
• Salt, to taste
• Pepper, to taste
• 2 eggs, beaten
• 1 (17 ounce) package puff pastry, defrosted (2 sheets)

Equipment Needed

• Large pot
• Large skillet
• Potato masher or grater
• Mixing bowl
• Rolling pin
• Baking sheet
• Parchment paper (optional)
• Knife

Instructions

1. Begin by defrosting the puff pastry sheets in your refrigerator. This usually takes about 30-40 minutes.
2. Next, parboil the potatoes. Place the unpeeled potatoes in a large pot, cover with cold water, and bring to a boil. Cook until they are fork-tender, about 15-20 minutes.
3. Drain the potatoes, and let them cool slightly until you can handle them comfortably.
4. Once cooled, peel the potatoes. Then, either grate or mash them until you have a smooth consistency. Set aside.
5. Now, prepare the onions. Heat the oil in a large skillet over medium to high heat.
6. Add the minced onions to the skillet and season with salt and pepper to taste.
7. Saute the onions until they are golden brown and softened, stirring occasionally. The more color you develop, the more flavor you’ll get. Be careful not to burn them! Cool and set aside.
8. In a large mixing bowl, combine the mashed potatoes, sauteed onions, and beaten eggs. Mix well until everything is evenly incorporated. At this point, you can add any other desired fillings.
9. Lightly flour a clean work surface.
10. Unfold one sheet of puff pastry onto the floured surface. Use a rolling pin to gently roll out the pastry sheet until it is approximately 12 inches long, maintaining the width of the original sheet.
11. Slice the puff pastry sheet in half lengthwise, creating two long rectangles.
12. For each piece of dough, spread one-quarter of the potato filling along the long side of the dough, creating a long, thin mound of filling.
13. Carefully fold the dough over the filling and roll it up jelly-roll fashion. Pinch the ends shut to seal in the filling.
14. Repeat steps 10-13 with the remaining puff pastry sheet and potato filling.
15. Place the prepared potato rolls on a baking sheet lined with parchment paper (optional, but recommended for easy cleanup).
16. Bake at 400°F (200°C) for approximately 20 minutes, or until the tops are nicely golden brown. Keep a close eye on them, as baking times may vary slightly depending on your oven.
17. Remove the baking sheet from the oven and let the potato rolls cool slightly before slicing.
18. Once cooled, slice each roll into approximately 8 pieces.
19. Serve warm and enjoy!

Expert Tips & Tricks

• For extra flavor, consider adding a clove or two of minced garlic to the onions while sauteing.
• Don’t overwork the puff pastry. Handle it gently to maintain its flaky layers.
• If you’re short on time, you can use store-bought mashed potatoes, but freshly mashed will always yield the best flavor.
• For a richer flavor, brush the tops of the rolls with melted butter or an egg wash before baking.
• Make-ahead tip: Prepare the potato filling a day in advance and store it in the refrigerator. This allows the flavors to meld together even more.

Serving & Storage Suggestions

Serve these savory potato rolls warm as a side dish, appetizer, or snack. They pair wonderfully with a dollop of sour cream or a sprinkle of fresh parsley.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until warmed through. You can also reheat them in a microwave, but they may lose some of their crispiness.

For longer storage, these potato rolls can be frozen. Wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 2 months. To reheat from frozen, bake in a preheated oven at 375°F (190°C) for about 20-25 minutes, or until heated through.

FAQs (Frequently Asked Questions)

Q: Can I use pre-made mashed potatoes?
