Crispy Sesame Potato Pockets with Flaky Puff Pastry Step-by-step instructions

Before you start

Before starting, ensure the puff pastry is thawed but still cold. Boil the potatoes until fork-tender, then peel and set aside. Finely chop the onion and herbs.

Line a baking sheet with parchment paper. Preheat the oven to 400°F (200°C). Have all ingredients and equipment ready to streamline the assembly process.

Instructions

Phase 1: Flavorful Filling

1. 1Make the Filling
   In a large bowl, mash the boiled potatoes with a potato masher until smooth but still slightly chunky. Add the sautéed onions, tomato paste, chopped fresh herbs, salt, and black pepper. Mix until everything is well combined. Taste and adjust seasoning if needed. The filling should be thick and hold together when formed into balls.
   Look for The filling is fragrant with herbs and holds its shape when pressed.
   Tip For extra flavor, sauté the onions in a little olive oil until golden before adding to the potatoes.
2. 2Form the Filling Balls
   Using your hands, roll the potato mixture into 12 walnut-sized balls, about 1 inch in diameter. Set them aside on a plate. If the mixture is too sticky, lightly wet your hands with water. If too dry, add a teaspoon of water or olive oil.
   Look for The balls are uniform in size and hold together without cracking.
   Tip Chill the formed balls for 10 minutes to make them easier to handle.

The potato filling is smooth and well-seasoned, with visible specks of herbs and a rich aroma. The mixture holds together when formed into balls without being too sticky or too dry. The onions are soft and translucent, and the tomato paste has deepened the color to a warm orange-red.

Phase 2: Assembly

3. 3Prepare the Pastry
   Lay the puff pastry sheets on a lightly floured surface. Brush each sheet generously with the egg white. Sprinkle the sesame seeds evenly over the egg white, pressing gently so they stick. The entire surface should be covered with a generous sesame crust.
   Look for The pastry is evenly coated with sesame seeds, with no bare spots.
   Tip Work with one sheet at a time to keep the pastry cold.
4. 4Cut and Fill the Pastry
   Cut each sesame-coated pastry sheet into 2 equal rectangles. Place one potato ball in the center of each rectangle. Fold the pastry over the filling to create a half-moon shape. Press the edges firmly with a fork to seal, ensuring no filling escapes.
   Look for The pockets are well sealed with a fork pattern on the edges.
   Tip If the pastry becomes too soft, chill it for 5 minutes before filling.

The pastry sheets are evenly coated with sesame seeds, creating a thick crust. The filling balls are neatly wrapped, with edges firmly sealed and a fork pattern pressed around the borders. The pockets are uniform in size and shape, ready for the egg wash and baking.

Phase 3: Baking and Finishing

5. 5Brush with Egg Yolk
   Place the filled pockets on a baking sheet lined with parchment paper, seam side down. Brush the exposed pastry with the egg yolk, covering the tops and edges. This will give the pockets a beautiful golden sheen as they bake.
   Look for The pastry is coated with a shiny egg wash, ready for baking.
   Tip For an extra-glossy finish, apply a second coat of egg yolk after the first dries slightly.
6. 6Bake the Pockets
   Preheat the oven to 400°F (200°C). Bake the pockets for 20-25 minutes, until the pastry is puffed, deeply golden, and crisp. The sesame seeds will toast and become fragrant. If the tops brown too quickly, loosely tent with foil.
   Look for The pockets are golden brown, puffed, and the sesame seeds smell toasted.

   Tip Rotate the baking sheet halfway through for even browning.
7. 7Cool and Serve
   Remove from the oven and let the pockets cool on the baking sheet for 5 minutes before serving. The filling will be hot and steaming. Serve warm, snapping one open to reveal the fluffy herbed potato filling and the crispy, crackling layers.
   Look for The pockets are warm, with a loud crunch when broken.
   Tip These are best eaten fresh out of the oven while the pastry is at its crispiest.

The pockets are golden brown all over, with the pastry puffed and flaky. The sesame seeds are toasted and release a nutty aroma.

When broken open, the pastry shatters with a loud crunch, and steam rises from the fluffy, herbed potato filling. The filling is hot and creamy, with a perfect balance of herbs and seasoning.

Common mistakes

One common mistake is overfilling the pockets, which can cause them to burst open during baking. Use a modest amount of filling and ensure the edges are well sealed. Another pitfall is under-baking, which results in soggy pastry.

Bake until the crust is deeply golden and sounds hollow when tapped. Also, avoid using wet potatoes, as they can make the filling too loose and cause the pastry to become soggy.

How to tell it’s done

The pockets are done when the pastry is deeply golden brown, puffed, and crispy to the touch. The sesame seeds will be toasted and fragrant.

To be safe, if you want to check the filling, insert an instant-read thermometer into the center of a pocket; it should read at least 160°F (71°C) for the egg wash to be fully cooked. Let them cool for a few minutes before serving.
