Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper. This step ensures that your sausage rolls bake evenly and don’t stick to the pan.
Prepare the Puff Pastry:
Divide the puff pastry into two equal parts. On a lightly floured surface, roll out each piece of puff pastry to a rectangle approximately 35 cm x 25 cm (14 inches x 10 inches) in size. The pastry should be thin but not so thin that it tears easily.
Spread the Tomato Sauce:
Spread half of the tomato sauce evenly over one rectangle of puff pastry, leaving a small border around the edges. This will help the pastry stick together when you roll it. Repeat with the second piece of puff pastry.
Add the Sausages:
Place the sausages on top of the tomato sauce, spacing them evenly. Depending on the size of the sausages, you may need to trim them to fit or overlap slightly. Make sure the sausages are positioned in a way that will allow you to roll the pastry easily.
Add the Cheese:
Sprinkle the shredded cheese evenly over the sausages. The cheese adds a delicious, melty layer that complements the savory sausage and tangy tomato sauce.
Roll the Pastry:
Carefully roll the puff pastry over the sausages, starting from one edge and rolling tightly to enclose the filling. Press the edges to seal, and use a little water if needed to help the edges stick. Repeat with the second piece of puff pastry.
Cut and Score the Rolls:
Using a sharp knife, cut each rolled pastry into bite-sized pieces, about 5 cm (2 inches) wide. Place the pieces seam-side down on the prepared baking sheet. Lightly score the top of each roll with a knife to allow steam to escape during baking.
Prepare the Egg Wash:
In a small bowl, beat the egg with a tablespoon of water to create an egg wash. Brush the top of each sausage roll with the egg wash. This will give the pastry a beautiful golden color and a glossy finish when baked.
