Description

This Sourdough Discard Italian Stromboli is a savory, cheesy rolled Italian bread filled with layers of provolone, mozzarella, salami, pepperoni, roasted red peppers, and flavorful pizza sauce and basil pesto. Made with a tender sourdough discard and Greek yogurt dough, it’s baked to golden perfection on a pizza stone for a crispy crust and soft, melty interior. Served hot and perfect for sharing, this stromboli pairs wonderfully with hot honey drizzled on top for a sweet-spicy kick.


Ingredients

Scale

Dough

  • 1 1/2 cups (213g) “00” flour or all-purpose flour
  • 2 tsp (9g) baking powder
  • 1/4 tsp (2g) baking soda
  • 1 tsp (6g) salt
  • 1 cup (250g) Greek yogurt
  • 1/2 cup (145g) sourdough discard (substitute: 1/2 cup more Greek yogurt)

Fillings and Toppings

  • 1/4 cup basil pesto
  • 1/2 cup pizza sauce
  • 1/4 cup roasted red peppers
  • 4-5 slices provolone cheese
  • 5-6 slices thinly sliced deli salami
  • 7-8 slices thinly sliced deli pepperoni
  • 3/4 cup shredded mozzarella cheese

Finishing

  • 1 egg, beaten, for egg wash
  • Sesame seeds, for topping
  • Italian seasoning, for topping
  • Freshly grated parmesan cheese, for topping
  • Hot honey, for serving


Instructions

  1. Preheat Oven: Preheat your oven to 400°F (205°C) and place a pizza stone inside to heat for at least 30 minutes. Alternatively, you can line a baking sheet with parchment paper if a pizza stone is unavailable.
  2. Mix the Dough: In a large bowl, combine the flour, baking powder, baking soda, and salt. Add the Greek yogurt and sourdough discard, mixing until a shaggy dough forms.
  3. Knead the Dough: Transfer the dough to a floured surface and knead with your hands until smooth, soft, and slightly sticky yet supple. If too wet, add flour one tablespoon at a time until manageable. Shape into a ball and let rest for 10-15 minutes.
  4. Roll the Dough: Place the dough onto a floured piece of parchment paper and roll it out into an approximately 8 by 12-inch rectangle.
  5. Add Sauces and Fillings: Spread basil pesto and pizza sauce evenly over the dough surface. Layer roasted red peppers, provolone, salami, pepperoni, and shredded mozzarella cheese on top.
  6. Form the Stromboli: Brush the dough edges with beaten egg wash. Starting from a short end, fold in the sides and tightly roll the dough into a log, sealing the edge. Place seam side down on the parchment paper.
  7. Prepare for Baking: Brush the top of the stromboli with more beaten egg wash. Sprinkle sesame seeds, Italian seasoning, and freshly grated parmesan cheese on top. Make small slits on the top with a sharp knife to allow steam to escape.
  8. Bake: Using a pizza peel or pan, transfer the stromboli on the parchment paper onto the preheated pizza stone. Bake at 400°F (205°C) for 20-25 minutes until the crust is golden and crispy.
  9. Rest: Remove the stromboli from the oven and let it rest for 5 minutes before slicing to allow the fillings to set.
  10. Serve: Slice and serve hot. Drizzle with hot honey and offer extra pizza sauce on the side for dipping.
  11. Enjoy: Enjoy your homemade sourdough discard Italian stromboli warm for the best flavors and texture.

Notes

  • You can substitute all-purpose flour if you don’t have “00” flour, though the texture may be slightly different.
  • If you don’t have sourdough discard, replace it with an equal amount of Greek yogurt for similar moisture and tang.
  • Adjust the fillings based on your preference—feel free to add mushrooms, olives, or other favorite pizza toppings.
  • Use parchment paper to easily transfer the stromboli onto the pizza stone and prevent sticking.
  • Allow the stromboli to rest before slicing to avoid the filling oozing out.
  • Drizzling hot honey on top adds a delightful sweet-spicy contrast to the savory filling.
