Place parchment paper on a baking sheet that's 13x18 inches.
02 -
Dust a work surface lightly with flour. Stretch or roll out the dough into a 10x12-inch shape, aiming for a ¼-inch thickness. Avoid over-thinning it.
03 -
With the dough's long side nearest you, brush olive oil over it, leaving an inch-wide edge all around. Scatter the minced garlic and dried oregano evenly on top, followed by a few red pepper flakes if using. Sprinkle pecorino romano to finish.
04 -
Place provolone slices evenly across the cheese layer. Add the ham on top, followed by mozzarella, then the cured meats. Brush the dough edges with a bit of beaten egg—save the extra for later.
05 -
Bring the dough's bottom third to the middle, then fold the top over the bottom, creating a big log. Pinch the edges to seal the seam and place the log seam-side down on the baking sheet. Tuck and seal the log's ends tight.
06 -
Cover the log loosely with plastic wrap and leave it on the counter for an hour, letting it rise slightly. It might not look drastically different afterward, so don’t stress.
07 -
Move an oven rack to the center spot and heat it up to 375°F. Coat the top of the dough with the leftover egg wash. Slash five ½-inch-deep cuts spaced evenly across the top (about 1½ inches long each).
08 -
Bake for roughly 35 minutes, or until it's golden, puffy, and the inside cheese is melty (200°F if using a thermometer). If grease or melted cheese seeps out, that’s normal—just blot it off with a paper towel.
09 -
Let the stromboli sit on the baking sheet for about 15-20 minutes to cool a bit. Move it to a cutting board, slice it into 1-inch pieces, and serve warm or at room temp. Offer marinara sauce for dipping if you’d like.
