Sourdough Discard Pizza Dough
A same-day sourdough discard pizza dough using unfed starter plus a little yeast, or a long cold ferment for more flavor — with clear steps for stretching and baking hot.

This sourdough discard pizza dough is the easiest way to spend a jar of unfed starter you'd otherwise wash down the sink. A little instant yeast makes it a same-day bake with a light, crisp crust, or you can leave the yeast out and cold ferment for days to grow a real sour tang. Either way you get a chewy, blistered base that beats store-bought dough.
Why this dough works
Unfed discard brings flavor and a little wild yeast, but on its own it's too slow for a same-day pizza. A small pinch of instant yeast does the heavy lifting for rise while the discard adds the sour depth and a more interesting crumb than plain yeast dough. The olive oil keeps the crust tender and helps it brown.
Same-day vs cold ferment
The yeast version is ready in about 4 hours and tastes clean with a mild tang — great for a weeknight. The no-yeast cold ferment trades time for flavor: the starter slowly ferments the dough in the fridge, developing acidity and a more open structure. If you've got the fridge space, 48 hours is the sweet spot.
Stretching without tears
Cold or tight dough fights you, so always rest the shaped balls before stretching and work at room temperature. Stretch from the edges, not the center, and resist the rolling pin — it crushes the bubbles that give pizza its light bite. If it springs back, rest it another 10 minutes.
Baking it hot
Pizza fails most often from a cold oven, not a bad dough. Preheat your steel or stone for a full 45 minutes at the oven's maximum and load the pizza fast. Eight to ten minutes is enough; pull it when the rim is charred and the underside sounds hollow when tapped.

Ingredients
Weights in grams are the source of truth; cup measures are approximate.
- 200 g sourdough discard (unfed, straight from the fridge is fine)
- 250 g bread flour
- 50 g whole wheat flour (optional, for flavor)
- 160 g water (room temperature)
- 5 g fine salt
- 2 g instant yeast (about 3/4 tsp) — for the same-day version
- 10 g olive oil, plus more for the bowl and pan
Method
In a large bowl, combine the discard, bread flour, whole wheat flour, water, salt, yeast and olive oil. Mix with a damp hand or spatula until no dry flour remains and a shaggy dough forms.
Cover and rest for 20 minutes, then knead in the bowl for 2-3 minutes until smooth and slightly tacky. The dough should pass a gentle windowpane stretch.
For same-day: cover the bowl and let the dough rise at room temperature until puffy and about doubled, 2-3 hours depending on kitchen warmth. For more flavor, skip the yeast and cold ferment the dough in the fridge for 24-72 hours, then bring to room temperature before shaping.
Divide the dough into two equal pieces (about 330 g each) and shape each into a tight ball. Rest the balls seam-side down on a floured surface, covered, for 30-45 minutes so the gluten relaxes.
Place a pizza steel or stone on the top oven rack and preheat to 500-550°F (260-290°C) for at least 45 minutes. A hot surface is what crisps the base.
Stretch one ball by hand: flatten gently, then pull from the edges leaving a thicker rim, working to a 10-inch round. Avoid a rolling pin, which knocks out the gas.
Transfer to a floured peel or parchment, top lightly (too many wet toppings make it soggy), and slide onto the hot steel. Bake 8-10 minutes until the crust is charred at the edges and the base is crisp.
Rest 2 minutes before slicing so the crumb sets. Repeat with the second ball. Extra dough freezes well for up to a month.
Frequently asked questions
Can I make sourdough discard pizza dough without yeast?
Yes, just drop the yeast and give the dough a long cold ferment — 24 to 72 hours in the fridge. The unfed discard is slow, so the cold proof is what builds both rise and tang. Expect a denser, more flavorful crust than the yeast-assisted same-day version. For the active-starter version, see the [sourdough pizza crust](/sourdough-pizza-crust).
Why is my discard pizza crust tough or chewy?
Usually from over-kneading or rolling it too thin with a pin. Knead just until smooth, relax the dough before stretching, and stretch by hand so you keep some gas. A very high-protein flour can also make it chewy; swap some for all-purpose if it feels tight.
How long can I keep the dough in the fridge?
Up to 3 days cold fermented with yeast, or 3-4 days without yeast. Beyond that the dough over-ferments, turns slack and bakes sour and flat. For longer storage, freeze the shaped balls and thaw overnight in the fridge.
Do I need a pizza stone or steel?
It helps a lot but isn't required. A preheated inverted sheet pan or a cast-iron skillet gets close. The key is maximum heat from below, so preheat whatever you use for a full 45 minutes and bake as hot as your oven allows.
