Flaky, golden-brown homemade stromboli stuffed with pepperoni, mozzarella, and marinara sauce. A crowd-pleasing Italian-American classic that's perfect for dinner, game day, or slicing into appetizers.
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper and brush lightly with olive oil.
On a lightly floured surface, roll out the pizza dough into a 12x16 inch rectangle.
Spread 1 cup of marinara sauce evenly over the dough, leaving a 1-inch border around the edges.
Sprinkle mozzarella cheese over the sauce, then top with pepperoni, black olives, Italian seasoning, garlic powder, and Parmesan.
Tightly roll the dough from the longer side, sealing the seam and ends with a little water.
Place seam-side down on the prepared baking sheet. Brush the top with remaining olive oil and make three small slits to vent steam.
Bake for 25-30 minutes, or until golden brown and the internal temperature reaches 190°F (88°C).
Let rest for 5 minutes before slicing. Serve warm with remaining 0.5 cup marinara sauce for dipping.
Notes
For best results, do not overfill with sauce or cheese. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or air fryer.
