Step 1: Prepare the Dough
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Roll out the pizza dough into a rectangle, about 12x16 inches.
Step 2: Assemble the Stromboli
Spread the marinara sauce evenly over the dough, leaving a 1-inch border around the edges. Sprinkle with shredded mozzarella cheese and arrange the pepperoni slices on top. Sprinkle with Italian seasoning.
Step 3: Roll and Bake
Starting from the long side, roll the dough tightly into a log. Pinch the seams to seal. Place the stromboli seam-side down on the baking sheet. Brush the top with olive oil.
Step 4: Bake
Bake for 20-25 minutes, or until the stromboli is golden brown and the cheese is melted.
Step 5: Garnish & Serve
Garnish with fresh parsley and serve hot with extra marinara sauce for dipping.
