Sourdough Discard Italian Stromboli

Golden crust, bubbling melted cheese, savory meats, and the comforting tang of sourdough all come together in this irresistible Italian Stromboli. Each slice unveils a swirl of vibrant flavors, where gooey mozzarella melts into smoky cured meats and herbs, while the sourdough discard dough delivers a tender bite with just the right chew. Trust me, you’re going to love this one, because it’s as cozy as it is crowd-pleasing.

Behind the Recipe

This recipe was born out of the simple need to make use of sourdough discard without wasting it. I remember those early days of feeding my starter and wondering what to do with the excess. One evening, inspired by an Italian deli sandwich I adored, I rolled up my discard dough with meats and cheese, baked it until golden, and discovered something magical. It became a family favorite, turning leftovers into an occasion.

Recipe Origin or Trivia

Stromboli itself is a uniquely Italian-American creation, said to have originated in the 1950s in Pennsylvania. Named after the volcanic island of Stromboli, this rolled bread captures the drama of molten cheese spilling out like lava. Unlike calzones, which are folded pockets, Stromboli is rolled into a log, offering those stunning swirls when sliced. The sourdough twist is a more recent adaptation, giving it a tangy depth that pairs beautifully with the rich fillings.
