I start by tossing shredded chicken with buffalo sauce in a bowl until every piece is coated. Then I sprinkle in the chopped jalapeño and set it aside to rest while I prep the dough.
Next, I dust my surface with a bit of flour and roll the pizza dough into a rectangle about 12×16 inches. Making the dough even ensures it cooks uniformly.
I spread ranch dressing over the dough, then add mozzarella and cheddar first, followed by the buffalo chicken mixture and blue cheese crumbles if using. The layers of cheese melt into creamy pockets inside.
From the long edge, I carefully roll the dough like a jelly roll, making sure to pinch the seams tightly so nothing leaks. Then I place it seam‑side down on a baking sheet.
I brush the outside with beaten egg and sprinkle on Italian seasoning and sesame seeds for golden color and texture. A few slits on top help steam escape while baking.
Finally, I pop the stromboli into a preheated oven and bake until the crust is crisp and the cheese inside is ooey and melty. Once it’s cooled slightly, it’s ready to slice and serve.
