Ingredients in Sourdough Discard Italian Stromboli

Let’s build this delicious bundle of joy layer by layer:

Sourdough Discard

Gives the dough a soft texture and a beautiful, subtle tang. The flavor boost is so worth it.

All-Purpose Flour

Forms the structure of your stromboli dough—light and tender when baked.

Olive Oil

Adds richness and helps the dough stay soft and pliable.

Water

To bring the dough together and help with hydration.

Salt

Just enough to balance all those bold Italian flavors.

Instant Yeast (Optional)

Gives a little extra lift if you’re short on time or want a lighter result.

Mozzarella Cheese

Melty, stretchy, and essential. Use low-moisture mozzarella for best results.

Italian Deli Meats

Think salami, pepperoni, ham, or prosciutto—layer them up for that flavor bomb.

Provolone or Parmesan

For extra flavor depth and cheesiness.

Italian Seasoning

Adds that classic herby touch.

Egg (for Egg Wash)

Gives the crust that golden, bakery-style finish.

Instructions

Let’s roll into deliciousness step by step:

Make the Dough

In a large bowl, mix sourdough discard, flour, salt, olive oil, and water. Add a pinch of yeast if using. Knead until smooth, about 5–7 minutes. Cover and let rise for 1–2 hours (or overnight in the fridge).

Preheat Your Oven

Set it to 400°F (200°C). Line a baking sheet with parchment paper.

Roll Out the Dough

On a floured surface, roll the dough into a large rectangle—about 10×14 inches.

Layer the Fillings

Start with mozzarella, then your meats, provolone or Parmesan, and a sprinkle of Italian seasoning. Leave a 1-inch border all the way around.

Roll It Up

Starting from one long edge, roll the dough into a tight log. Pinch the seams and tuck the ends under.

Transfer & Score

Place seam-side down on your baking sheet. Use a sharp knife to make a few slits across the top.

Brush with Egg Wash

Whisk one egg with a splash of water and brush it all over the top for that shiny, golden crust.

Bake

Bake for 25–30 minutes, or until golden and bubbling at the edges. Let it cool for 10 minutes before slicing.

Serve

Slice into thick, warm pieces and serve with marinara or your favorite dipping sauce.

  • Lunchbox MVP: Let it cool, wrap it up, and it’s the sandwich upgrade you didn’t know you needed.

Additional Tips

  • Chill the Dough Overnight: For deeper flavor and a more relaxed baking day.
  • Seal It Well: To keep all that cheesy goodness inside.

FAQ Section

Q1: Can I use active sourdough starter instead of discard?
A1: Yes! Just expect a little more rise and a slightly more sour flavor.

Q2: Do I have to use yeast?
A2: Nope! The discard alone will leaven it if you give it enough time. Yeast just speeds things up.

Q3: Can I make this gluten-free?
A3: You can try with a 1:1 GF flour blend, but the dough may be more delicate.

Q4: Can I freeze it?
A4: Absolutely. Freeze fully baked slices or the whole stromboli wrapped tightly.

Q5: What cheeses work best?
A5: Mozzarella is a must, but provolone, fontina, and parmesan all bring amazing flavor.

Q6: Can I bake this in a loaf pan?
A6: You could! It’ll be a thicker loaf-style stromboli—just adjust the baking time.

Q7: How do I reheat leftovers?
A7: Warm in a 350°F oven for 10–15 minutes, or air fry for a crispier edge.

Q8: Can I make mini strombolis?
A8: Yes! Divide the dough and fillings into smaller portions—great for snacks or lunch prep.

Q9: What if I don’t have parchment paper?
A9: Use a well-greased baking sheet or a silicone mat.

Q10: Can I use store-bought pizza dough instead?
A10: Sure thing, but you’ll miss the lovely tang of the sourdough.

This Sourdough Discard Italian Stromboli is what cozy, melty, carb-loaded dreams are made of.
