Prepare the Dough: Divide the pizza dough into two equal sections. Let rest at room temperature until pliable.
Roll the Dough: Use your fingers or a rolling pin to roll each dough portion into a rectangle about 9 inches by 14 inches.
Layer the Fillings: Sprinkle 1/3 cup of mozzarella cheese down the center of each rectangle, leaving 1 to 2 inches of space on all sides.
Add the Meats: Layer with Genoa salame, pepperoni, and Italian sausage.
Add More Fillings: Top with another 1/3 cup of mozzarella cheese, a spoonful of fire-roasted diced tomatoes, and 1 tablespoon each of parsley and basil.
Finish the Filling: Sprinkle the remaining 1/3 cup of mozzarella on each stromboli.
Roll the Stromboli: Fold in the short sides, then roll up tightly from the long edge to form a log. Keep everything compact to avoid gaps.
Transfer to Baking Sheet: Place the stromboli seam-side down on a baking sheet lined with parchment paper.
Brush with Egg Wash: In a small bowl, whisk the egg with 1 tablespoon of water. Brush the mixture over each stromboli. Cut several shallow slits across the top to allow steam to escape.
Bake the Stromboli: Bake for 20 to 25 minutes, or until deep golden brown.
Finish and Serve: Brush the tops with olive oil and sprinkle with parmesan cheese and additional herbs if desired. Slice into 2-inch sections and serve hot with marinara sauce on the side.
Notes
Storage: Refrigerate in an airtight container for 3 to 4 days.Customization Tip: Making just one stromboli? You’ll only need half of the topping ingredients. Get creative with fillings: switch up the meats, cheeses, or herbs to suit your cravings.No Egg? No Problem: The egg wash creates that bakery-window golden glow, but olive oil or even a sprinkle of cheese before baking does the trick too.Dough Alert: Don’t roll the dough too thin or it’ll tear when you roll it up. This dough has great elasticity, so you can pack it with toppings and still get a nice, sealed log.Topping Overflow? If juices or toppings ooze out during baking, don’t panic. That’s just flavor escaping and it’s totally fine.
