Set a baking sheet with parchment paper and heat the oven to 200°C (392°F).
On a surface that has been lightly dusted with flour, roll out the puff pastry until it is about 2-3 mm (1/8 inch) thick.
Make rectangles out of the pastry, measuring about 10 cm x 12 cm (4 x 5 inches) or whatever size you choose.
Form each square of dough into a sausage by spooning the meat mixture down one side.
Seal the filling by folding the dough over it and pushing the edges together. A beautiful finish may be achieved by crimping the edges with a fork.
Lay the sausage rolls, seam side down, on the baking sheet that you had previously prepared.
Step Three: Egg Wash and Topping
To make the sausage rolls seem extra lustrous and golden when cooked, brush the tops with the beaten egg.
For a crunchier and more flavorful topping, sprinkle sesame seeds over the rolls.
4. Prepare the baking:
Sausage rolls should be baked in a preheated oven for twenty to twenty-five minutes, or until the puff pastry is golden and puffy.
After taking them out of the oven, let them on a wire rack to cool for a little before you eat.
5. After that, dig in!
