Making Tremendous Cheesy Pepperoni Stromboli is straightforward when you follow these easy-to-follow instructions:

1. Preheat Oven: Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

2. Roll Out Dough: On a lightly floured surface, roll out the pizza dough into a rectangular shape about 1/4 inch thick.

3. Layer Ingredients: Sprinkle the mozzarella cheese evenly over the dough, leaving a border around the edges. Next, add sliced pepperoni and finish with grated Parmesan cheese and Italian seasoning.

4. Roll the Dough: Carefully start rolling the dough from one end to the other, tucking in the sides as you go. This will create a tight roll.

5. Seal the Edges: Pinch the seams and ends of the rolled dough to seal them tightly.

6. Prepare for Baking: Transfer the rolled Stromboli to the prepared baking sheet. Brush the top with olive oil.

7. Create Egg Wash: In a small bowl, whisk together the egg and water. Brush this mixture over the top of the Stromboli for a golden finish.

8. Make Slits: Use a sharp knife to cut a few small slits on top of the Stromboli to allow steam to escape.

9. Bake: Place the baking sheet in the preheated oven and bake for 25-30 minutes, or until the crust is golden brown.

10. Serve Warm: Once baked, remove from the oven and allow it to cool for a few minutes. Slice and serve warm with marinara sauce for dipping.

Following these steps ensures you’re on your way to creating an incredible dish that everyone will love—simple yet delicious!
