Begin by melting the butter in the microwave or on the stove. If using the microwave, place the butter in a microwave-safe bowl and heat it for about 20-30 seconds or until fully melted.
Once the butter is melted, stir in the minced garlic, chopped parsley, and grated Parmesan cheese. The garlic will infuse the butter with a rich, aromatic flavor, while the parsley adds a hint of freshness, and the Parmesan provides a sharp, salty note. Set the mixture aside while you prepare the Stromboli.
Step 2: Prepare the Pizza Crust
Line a baking sheet with parchment paper. This will prevent the Stromboli from sticking to the sheet while also allowing it to cook evenly.
Unroll the Pillsbury pizza crust onto the prepared baking sheet. Stretch it out with your hands until it almost covers the entire baking sheet. The goal is to get it as thin as possible without tearing, as this will help the Stromboli cook evenly and ensure a crispy crust.
Step 3: Layer the Deli Meats
Begin layering the deli meats starting with the 8 slices of deli ham. Lay them out evenly over the pizza dough, leaving a small border along the edges. Next, layer the 10 slices of Genoa salami on top of the ham, followed by the 12 slices of pepperoni. The combination of meats will give the Stromboli a savory, slightly smoky flavor.
After the meats, layer the slices of provolone or mozzarella cheese on top of the meats. If you prefer shredded cheese, that works just as well — simply spread it evenly over the meats to create a layer of gooey, melty cheese.
Step 4: Roll and Seal the Stromboli
Carefully roll the Stromboli lengthwise, starting from one edge and rolling it tightly. Be sure to seal the seam well by pinching the edges together to avoid any filling spilling out during baking. This will help the Stromboli hold its shape and ensure a neat presentation when sliced.
Once the Stromboli is rolled, seal the ends by pinching them together as well. If there’s any excess dough, fold it underneath the Stromboli for a cleaner look. This step ensures that the Stromboli is fully sealed, preventing the filling from leaking while baking.
Step 5: Score the Top and Add the Garlic Butter
Using a serrated knife, make a few shallow slashes on the top of the Stromboli. These cuts will allow steam to escape during baking and help prevent the dough from puffing up too much.
Brush the entire top of the Stromboli with the garlic butter mixture that you prepared earlier. This will give the crust a golden, shiny finish and infuse it with the delicious garlic and Parmesan flavors.
Step 6: Bake
Bake the Stromboli in the preheated oven at the temperature indicated on the pizza crust packaging. Typically, this is around 375°F (190°C), but be sure to follow the instructions on the package. Bake for 20-25 minutes, or until the crust is golden brown and the cheese is melted and bubbling inside.
Once baked, remove the Stromboli from the oven and allow it to cool for a few minutes before slicing. This resting time will allow the cheese to set slightly, making it easier to cut and serve.
