Preheat oven to 200°C and line a baking sheet with parchment paper.

Lightly dust the work surface with flour and roll pizza dough into a 25 x 36 cm rectangle.
03 -
In a small bowl, beat the egg thoroughly.

Spread marinara sauce evenly over the dough, leaving a 2.5 cm border on all sides. Distribute mozzarella cheese uniformly over the sauce, then arrange pepperoni slices evenly atop the cheese.

Starting at the long edge, roll dough tightly into a log, jelly roll-style. Pinch the seam firmly and tuck the ends under.

Bake for 20–25 minutes, or until the crust becomes golden brown and crisp.

Remove stromboli from the oven and allow it to rest for 5–10 minutes before slicing into portions.
