These crackers are my go-to solution for that jar of unfed sourdough starter languishing in the fridge. They turn discard into something crisp, salty, and impossibly snackable in under an hour. No fancy technique, just a small handful of pantry staples and a rolling pin (or a wine bottle in a pinch).
I like that this recipe is forgiving: the dough comes together quickly, and the oven does most of the work. The result is paper-thin crackers with a toasty edge and a gentle sour note that pairs beautifully with cheese or a smear of hummus. You can keep things classic with Parmesan and Italian seasoning or make tiny adjustments depending on what you have.
Below you’ll find exactly what to buy, the ingredients list straight from the recipe, step-by-step directions, troubleshooting pointers, storage advice, and a few chef tips I use when I’m making them for guests. Read through once, then roll the dough and get baking.
What to Buy

Shop for the essentials if you don’t already have them. This is a short list and each item pulls double duty in other recipes.
- 1 cup (200 g) sourdough discard, unfed — this is the star and the reason for the recipe.
- Unsalted butter — melted for richness and crisping; it keeps the crackers from tasting too salty.
- All-purpose flour and a pinch of salt — the structure for the crackers.
- Olive oil — for brushing and helping the toppings stick.
- Italian seasoning and grated Parmesan — classic flavor partners here.
- Flaked sea salt — the finishing touch that brings the flavors alive.
Ingredients
- 1 cup (200 g) sourdough discard, unfed — provides the base, tang, and moisture; it’s the reason we’re making these crackers.
- 3 Tablespoons butter, unsalted and melted — adds richness and helps the crackers crisp as they bake.
- ¼ teaspoons salt — seasons the dough; keep it measured so the discard’s tang isn’t overwhelmed.
- 1 Tablespoon all-purpose flour — gives structure so the crackers hold together when baked and cut.
- olive oil, for brushing — helps toppings adhere and gives a golden sheen.
- 1-2 teaspoon Italian seasoning — adds savory herb notes; sprinkle to taste across the sheet.
- 1-2 Tablespoon grated parmesan — lends umami and browns beautifully on the crackers’ surface.
- ½ teaspoon flaked sea salt — a final sprinkle for texture and bright, finishing saltiness.
Sourdough Discard Crackers — Do This Next
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- In a bowl, mix 1 cup (200 g) unfed sourdough discard, 3 tablespoons melted unsalted butter, 1 tablespoon all-purpose flour, and 1/4 teaspoon salt until fully combined and smooth.
- Place the dough between two sheets of parchment paper. Roll the dough evenly until very thin, about 1/16-inch thick.
- Transfer the top sheet of parchment (with the rolled dough) onto the prepared baking sheet and peel off the top parchment.
- Brush the dough lightly with olive oil. Evenly sprinkle 1–2 teaspoons Italian seasoning and 1–2 tablespoons grated Parmesan over the surface.
- Bake on the middle rack for 15 minutes.
- Remove the baking sheet from the oven and, while the cracker sheet is still warm, use a pizza cutter or sharp knife to cut the dough into squares or desired shapes.
- Return the cut crackers to the oven and bake an additional 10–15 minutes, watching closely and removing when the edges are browned and the crackers are crisp.
- Remove from the oven and immediately sprinkle with 1/2 teaspoon flaked sea salt. Let the crackers cool completely on the baking sheet or a wire rack before separating and serving.
Why You’ll Keep Making It

These crackers are fast, thrifty, and reliable. If you bake with a sourdough starter, a jar of discard accumulates faster than you can use it; this recipe turns waste into something joyful. The dough is forgiving: it tolerates slight differences in hydration and still becomes crisp when rolled thin.
They’re versatile — they work as an everyday snack, an impromptu appetizer, or a crunchy element on a cheese board. There’s minimal clean-up and the ingredients are pantry staples you likely already have. For me, that combination of simplicity and flavor makes these a repeat recipe all year round.
If You’re Out Of…

Short answers for common shortages:
- If you’re out of unsalted butter — brush a little extra olive oil into the dough and on top before baking. The crackers will be slightly less rich but still crisp and tasty.
- If you don’t have Italian seasoning or Parmesan — skip them. The base cracker is still excellent with just olive oil and flaked sea salt at the end.
- If you’re low on flaked sea salt — a light sprinkle of table salt will work, but add it sparingly so the texture isn’t too sharp.
Toolbox for This Recipe
Tools you’ll reach for, and why they matter:
- Rolling pin (or a smooth bottle) — needed to roll the dough very thin so the crackers crisp.
- Parchment paper — makes rolling, transferring, and cleanup effortless.
- Baking sheet — choose a rimmed sheet that fits your rolled dough comfortably.
- Pastry brush — for a light, even coat of olive oil.
- Pizza cutter or sharp knife — cuts warm crackers cleanly so they finish crisping without crumbling.
- Wire rack — cools crackers quickly and prevents sogginess.
Pitfalls & How to Prevent Them
Common mistakes I see and quick fixes:
- Dough rolled too thick — won’t crisp through. Roll to about 1/16-inch; if it feels substantial, roll thinner. Use two sheets of parchment and press evenly.
- Toppings burn before crackers are done — herbs and cheese can darken quickly. Keep an eye during the second bake and remove trays when edges brown and centers are set.
- Crackers go soft after cooling — they need to cool completely before separating. If they still feel soft, return to the oven for a few minutes to dry out further.
- Uneven baking — rotate the pan halfway through the second bake if your oven has hot spots. Bake on the middle rack for the most even heat.
Variations by Season
Because the base is simple, small seasonal tweaks make a big difference.
- Spring — keep it light: a modest sprinkle of Italian seasoning is enough, letting the sourdough tang stand out.
- Summer — serve with chilled dips; the thin crackers are excellent for scooping lighter spreads.
- Autumn/Winter — lean into richness: a heavier dusting of Parmesan before the second bake deepens the savory profile and toasts nicely in cooler months.
Pro Perspective
Little adjustments that punch up the result:
- Roll as thin and even as you can — the difference between good and spectacular is the thickness. Use the parchment sandwich method and steady, even pressure.
- Keep an eye during the last 5 minutes — ovens vary and Parmesan or herb bits can go from golden to bitter quickly.
- Cut while warm — cutting the sheet while it’s still warm prevents cracking and gives you clean edges.
- Use a light hand with toppings — too much cheese or herbs can prevent even browning and create chewy spots.
Save for Later: Storage Tips
Completely cool the crackers before storing. Any residual warmth traps steam and leads to sogginess.
- Store in an airtight container at room temperature for up to a week. Placing a paper towel in the container helps absorb any trace humidity.
- If you want to keep them longer, freeze in a sealed bag with parchment between layers. Thaw at room temperature; they usually come back crisp.
Ask the Chef
Q: Can I use fed starter instead of unfed discard?
A: Yes, but fed starter is more active and wetter; you may need to add a touch more flour to reach a workable consistency. The flavor will be less tang-forward than with unfed discard.
Q: Can I make flavored batches (garlic, seeds)?
A: Keep toppings light so they don’t prevent the cracker from drying out. Sprinkle spices or seeds sparingly and watch the second bake closely for browning.
Q: My crackers aren’t crisp — what went wrong?
A: Most likely they were rolled too thick or removed from the oven too early. Let them cool fully; if they still feel soft, bake a few more minutes at a lower temperature to dry them out without burning.
Final Bite
These Sourdough Discard Crackers are one of those small kitchen wins that save food and reward you quickly. They’re simple, adaptable, and perfect for sharing. Once you’ve tried one batch, you’ll see why I keep a jar of discard in the fridge — it’s a shortcut to crunchy, savory snacks and an easy way to honor every bit of starter you feed.
Make the dough, roll thin, watch the edges, and enjoy a stack of crisps with something you love. And if you tweak them, I’d love to hear what you tried—tiny changes often lead to the best discoveries.
