3 Ingredient Sourdough Discard Crackers (Fully Fermented, No Added Flour)
Sourdough discard crackers are made with three ingredients: discard, melted salted butter, and dried Italian seasoning. No added flour and no rolling. You spread the batter straight onto the pan at an eighth of an inch, pre-bake for ten minutes so it scores cleanly, then bake until it snaps. Fifty minutes total, five of them hands-on, and about forty to fifty crackers.

Why These Sourdough Discard Crackers Have No Added Flour
Most sourdough discard crackers recipes stretch the discard with raw all-purpose flour, which means part of the finished cracker never went through the starter. This one uses discard as the entire structure, so every bit of flour in the batch is fermented. It also removes the dough stage altogether: nothing to knead, nothing to rest, nothing to roll, which is what makes these easy sourdough discard crackers rather than a project.
The trade-off is that the batter is loose rather than doughy, so thickness is the only variable that matters. Even at an eighth of an inch, it dries into a sheet you can break by hand.
Key Ingredients for Sourdough Discard Crackers
- Sourdough discard, unfed and ideally a few days old for more tang. Let the cold discard loosen at room temperature first, or it will drag under the spatula. If you are still building a supply, make a sourdough starter from scratch and keep it going by feeding and maintaining it. A week of baking sourdough sandwich bread leaves plenty.
- Salted butter, melted. The fat is what makes the sheet snap instead of bend, and it carries the only salt in the batter. Unsalted butter needs a pinch of fine salt added.
- Dried Italian seasoning, stirred through rather than scattered on top. Dried herbs survive forty-five minutes, whereas fresh ones scorch. Herbes de Provence, rosemary, or everything bagel seasoning all work.
How to Make Sourdough Discard Crackers
- Heat the oven to 325°F and line a large baking sheet with parchment.
- Stir the discard, melted butter, and dried herbs together until smooth.
- Spread onto the parchment to an eighth of an inch or thinner, as evenly as you can. Sprinkle with flaky sea salt if using.
- Bake for 10 minutes, until the surface is set and still pale.
- Score into squares with a pizza cutter.
- Bake another 30 to 35 minutes, lifting out pieces that crisp early.
- Cool completely on the pan, then break along the score lines.
Tips for Crisp Sourdough Discard Crackers
- Even thickness is the whole recipe. Sourdough discard crackers spread thicker than an eighth of an inch stay bendy in the middle while thin edges over-brown. Spread thinner than feels right.
- Score at 10 minutes, not before. The surface is firm enough to cut cleanly. Scoring wet batter drags and smears.
- No docking needed. At this thickness, there is not enough batter to trap steam.
- Judge by sound, not color. A cooled cracker should snap audibly. If it bends, give it another five to ten minutes.
- Pull crisp pieces early. After around 30 minutes, lift out anything already done and return the rest.
- Older discard tastes sharper, which suits these. If your starter is behaving strangely, 15 common mistakes beginners make with sourdough cover what is normal and what is not.
Variations on Sourdough Discard Crackers
- Dairy-free: olive oil in place of the butter, plus a pinch of salt.
- Parmesan: a handful stirred in. Browns faster, so check five minutes earlier.
- Everything bagel: in the batter and scattered on before the first bake so the seeds set.
- Sweet: cinnamon and sugar instead of herbs, same temperature.
What to Serve With Sourdough Discard Crackers
These sourdough discard crackers are sturdy enough for a thick dip without snapping in the bowl. The herbs in the batter pair with anything from the Greek yogurt dressings and dips collection.
Sourdough discard crackers also pack well, since there is no moisture in them to soften by noon. Bake a sheet on the weekend, and they carry it during the week alongside 25 lunchbox snacks for picky eaters.
Sourdough Discard Crackers FAQs
Thickness, almost every time. Anything spread past an eighth of an inch holds moisture in the middle. The other cause is judging them warm, since they firm up as they cool. A cooled cracker that still bends goes back in at 325°F for five to ten minutes.
Yes, but it behaves differently. A recently fed starter is full of air and puffs slightly rather than drying flat, so the crackers come out lighter and less snappy. Unfed discard gives the denser, sharper result that these are built around.
About ten days in an airtight jar, provided they were completely cool going in. Any residual warmth turns to moisture and softens the batch overnight.
No. Doubling on a single sheet doubles the thickness, which is the one thing that ruins them. Use two pans and rotate them halfway through the second bake.

Ingredients
- 1 cup sourdough discard stirred
- 2 tablespoons salted butter melted
- 1 teaspoon dried Italian seasoning
- Flaky sea salt to finish (optional)
Instructions
- Heat the oven to 325°F. Line a large baking sheet with parchment paper.
- Add the sourdough discard, melted butter, and dried Italian seasoning to a bowl. Stir until well combined and smooth.
- Pour onto the parchment and spread into a very thin, even layer, about ⅛ inch thick or thinner. Even thickness matters more than shape. Sprinkle with flaky sea salt if using.
- Bake for 10 minutes, until the surface is set and firm to the touch but still pale.
- Remove the pan and score the sheet into small squares with a pizza cutter or sharp knife.
- Return to the oven for another 30 to 35 minutes, until golden and crisp. Check at 30 minutes and lift out any pieces already crisp, returning the rest to finish.
- Cool completely on the baking sheet, then break apart along the score lines.
Notes
- Spread to ⅛ inch or thinner. Thick patches stay bendy while thin edges over-brown.
- Let the cold discard come to room temperature so it spreads evenly instead of dragging.
- No docking needed at this thickness.
- Judge by sound. A cooled cracker should snap audibly. If it bends, bake for another 5 to 10 minutes at 325°F.
- Unsalted butter: add a pinch of fine salt, since the butter carries the only salt in the batter.
- Dairy-free: swap the butter for the same amount of olive oil plus a pinch of salt.
- Store in an airtight container at room temperature for about 10 days. Refresh in a 325°F oven for 5 minutes.
- Older discard gives a sharper, more sour cracker.
