Creating your Cheesy Pepperoni Stromboli is simple! Just follow these steps:

1. Preheat your oven: Set it to 400°F (200°C).
2. Prepare the dough: Roll out the pizza dough on a floured surface into a rectangle, about 12×15 inches.
3. Spread ricotta: Evenly spread the ricotta cheese over the dough, leaving a small border around the edges.
4. Add fillings: Sprinkle the shredded mozzarella cheese, sliced pepperoni, and grated Parmesan cheese on top of the ricotta.
5. Season: Sprinkle Italian seasoning over the cheese and pepperoni for added flavor.
6. Roll the dough: Starting from one long edge, carefully roll the dough into a log, tucking in the edges as you go to secure the filling.
7. Seal the edges: Pinch the seams closed, ensuring the filling doesn’t escape during baking.
8. Prepare for baking: Place the stromboli seam-side down on a baking sheet lined with parchment paper.
9. Egg wash: Beat the egg and brush it over the top of the stromboli to achieve a beautiful golden color.
10. Cut slits: Make a few shallow cuts on top of the dough to allow steam to escape during baking.
11. Bake: Place the stromboli in the preheated oven and bake for 25-30 minutes or until golden brown.
12. Cool down: Remove from the oven and let cool for a few minutes before slicing.

Following these steps will ensure your Cheesy Pepperoni Stromboli turns out perfectly every time!
