How to Make Sourdough Discard Italian Stromboli
Prepare the Dough: In a bowl, mix the 00 flour, baking powder, baking soda, salt, Greek yogurt, and sourdough discard. Knead until slightly tacky, then let it rest for about 10-15 minutes.
Roll Out the Dough: Lightly flour your surface, and roll the dough into a rectangle about ¼ inch thick; this will be the canvas for your delicious fillings.
Layer Fillings: Spread a generous layer of pizza sauce and basil pesto on the dough. Then, scatter roasted red peppers, provolone, salami, pepperoni, and mozzarella evenly across the surface.
Shape the Stromboli: Carefully roll the dough tightly, ensuring the fillings stay tucked inside. Pinch the seams closed firmly, ensuring no filling escapes during baking.
Prepare for Baking: Place the rolled Stromboli seam-side down on a baking sheet. Brush the top with an egg wash, sprinkle sesame seeds, and cut slits on top to allow steam to escape while baking.
Bake: Preheat your oven to 400°F (204°C) and bake the Stromboli for 20-25 minutes, or until the crust is golden brown and crispy.
Cool and Serve: Allow the Stromboli to cool for 5-10 minutes before slicing. For a delightful twist, drizzle hot honey over the top just before serving!
Optional: Serve with extra pizza sauce or marinara for dipping.
