Step-by-Step Directions
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and set aside.
Step 2: Roll Out the Dough
On a lightly floured surface, roll out the refrigerated pizza dough into a large rectangle, approximately 12×16 inches.
Step 3: Add the Sauce and Cheese
Spread the marinara sauce evenly over the rolled-out dough, leaving about a 1-inch border around the edges. Sprinkle the shredded mozzarella and grated Parmesan cheeses evenly over the sauce.
Step 4: Layer the Fillings
Layer the pepperoni, sliced ham, and crumbled Italian sausage over the cheese. Add the sliced bell peppers and onions on top. Sprinkle with dried oregano, dried basil, and garlic powder for added flavor.
Step 5: Roll the Dough
Carefully roll up the dough from one of the long sides, jelly-roll style, ensuring that the fillings stay inside. Pinch the seams and ends to seal the roll.
Step 6: Transfer and Brush
Transfer the Stromboli roll to the prepared baking sheet, seam-side down. Brush the top with the beaten egg to give it a golden, shiny crust.
Step 7: Bake the Stromboli
Bake in the preheated oven for 20-25 minutes, or until the crust is golden brown and cooked through. Allow the Stromboli to cool for a few minutes before slicing.
Step 8: Slice and Serve
Using a sharp knife, slice the Stromboli into 1-inch pieces. Serve warm with extra marinara sauce on the side for dipping.
Tips and Variations
- Vegetarian Option: Skip the meats and add more veggies like mushrooms, spinach, and olives.
- Cheese Lovers: Add more varieties of cheese such as provolone or cheddar for an extra cheesy Stromboli.
- Spicy Kick: Add sliced jalapeños or a sprinkle of red pepper flakes for a spicy version.
