Prepare the Dough:

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or a silicone mat. Roll the pizza dough into a rectangle, approximately 10x14 inches, on a floured surface.

Assemble the Fillings:

Spread a thin layer of marinara sauce over the dough, leaving a 1-inch border around the edges. Layer pepperoni, salami or ham, and shredded mozzarella evenly. Sprinkle Parmesan cheese, garlic powder, Italian seasoning, and red pepper flakes if desired.

Roll the Stromboli:

Starting from one long edge, tightly roll the dough into a log. Pinch the seam and edges to seal securely. Place the stromboli seam-side down on the prepared baking sheet.

Apply the Egg Wash:

Brush the entire stromboli with the beaten egg using a pastry brush. Sprinkle sesame seeds or dried oregano on top for extra flavor. Use a knife to make 4–5 slits on the top of the dough to release steam while baking.

Bake the Stromboli:

Bake in the preheated oven for 20–25 minutes or until the crust is golden brown and fully cooked.

Serve:

Let the stromboli cool for 5–10 minutes before slicing into 1-inch pieces. Serve warm with extra marinara sauce for dipping.
