Ingredients for Sourdough Discard Crackers

For the Crackers

• 1 cup sourdough discard, unfed and room temperature (240g)
• 1 cup all-purpose flour (125g)
• 2 tablespoons olive oil
• ½ teaspoon fine sea salt
• 1–2 tablespoons water, if needed

For the Topping

• 1 tablespoon mixed dried herbs (oregano, thyme, rosemary, or Italian herb mix)
• Flaky sea salt for finishing (optional but recommended)

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C).

Step 2: Make the Dough

In a large bowl, stir together the sourdough discard, flour, olive oil, and salt until a soft dough forms. It should feel smooth and slightly tacky but not sticky — it should pull away cleanly from the sides of the bowl. If the dough feels too dry and won’t come together, add water one tablespoon at a time until it does.

Step 3: Roll It Thin

Place the dough between two sheets of parchment paper. Roll as thin as you possibly can — almost paper thin. This is the most important step. Thick dough produces chewy crackers. Paper-thin dough produces crackers that shatter when you bite into them. Roll farther than feels comfortable.

Step 5: Score the Dough

Use a sharp knife or a pizza cutter to score the dough into cracker-sized squares or rectangles — about 1.5 to 2 inches each. You don’t need to cut all the way through; scoring the lines is enough. The crackers will break along them cleanly after baking.

Step 5: Add the Toppings

Remove the top sheet of parchment. Brush the surface lightly with a small drizzle of olive oil. Sprinkle the mixed dried herbs evenly across the entire surface, then press them gently into the dough so they adhere and don’t fall off during baking. Finish with a pinch of flaky sea salt if using.

Step 6: Bake

Slide the parchment paper with the dough directly onto a baking sheet. Bake for 18–22 minutes until the crackers are golden and visibly crisp. The edges will color first — that’s fine. Check at 18 minutes and give them more time if the center still looks pale or bendable.

Step 7: Cool and Break

Remove from the oven and let the crackers cool completely on the parchment before breaking along the scored lines. They firm up and crisp fully as they cool — don’t try to break them while still warm or they’ll bend instead of snap.

Pro Tips

Roll as thin as possible. Seriously — thinner than you think. Sourdough discard crackers need to be nearly translucent to get that satisfying snap. Use a rolling pin and lean into it. The dough is forgiving and won’t tear easily.

Use room temperature discard. Cold discard is stiffer and harder to roll thin. Leave it out for 30 minutes before starting if it’s been refrigerated.

Press the herbs in firmly. A light sprinkle sits on the surface and falls off when you handle the crackers. Press the herbs into the dough with your palm or the flat bottom of a glass so they’re embedded.

Score deeply enough. If the scored lines are too shallow they’ll disappear during baking and you’ll be breaking crackers freehand. Go over the lines with some pressure to make sure they stay visible after baking.

Cool completely before breaking. Warm crackers flex rather than snap. Give them the full cooling time on the tray — it only takes 10 minutes and makes a huge difference to the final texture.

Variations & Customizations

• Parmesan crackers — Sprinkle a small amount of finely grated Parmesan over the herbs before baking for a salty, nutty finish that makes these completely irresistible.
• Everything bagel seasoning — Swap the dried herbs for everything bagel seasoning for a savory, seedy topping that pairs beautifully with cream cheese.
• Sesame and black pepper — Sprinkle sesame seeds and a generous amount of cracked black pepper over the surface for an earthy, slightly spicy cracker.
• Rosemary and sea salt only — Keep it simple — just fresh or dried rosemary and a pinch of flaky salt. One of the best combinations there is.
• Add garlic powder — Stir ¼ teaspoon of garlic powder into the dough before rolling for a subtle garlic flavor throughout every cracker.
• Whole wheat version — Replace half the all-purpose flour with whole wheat flour for a nuttier, slightly heartier cracker with more depth of flavor.

Storage

Method	Details
Room Temperature	Store in an airtight container at room temperature for up to 1 week. Keep away from moisture — even a slightly damp container will make them lose their crispness.
Refreshing	If crackers soften, spread them on a baking sheet and bake at 300°F (150°C) for 5 minutes. They’ll crisp back up as they cool.
Freezing	Not recommended — the texture suffers after freezing and thawing. These are best made fresh and kept at room temperature.

Frequently Asked Questions

Why are my crackers chewy instead of crispy?

Almost always because the dough was rolled too thick. Even a millimeter of extra thickness makes a significant difference between crispy and chewy. Roll farther than feels right, check that you can nearly see through the dough, and make sure they bake until fully golden — not just lightly colored.

Can I use fresh herbs instead of dried?

Yes. Finely chopped fresh rosemary, thyme, or parsley all work beautifully. Fresh herbs have more moisture than dried, so press them in firmly and make sure the crackers bake until fully crisp. Dried herbs are slightly more reliable for this recipe, but fresh give a more vibrant flavor.

Can I add cheese to the dough?

Yes. Stir 2–3 tablespoons of finely grated Parmesan directly into the dough before rolling for cheese flavor throughout. You can also sprinkle grated Parmesan on the surface before baking — both approaches are excellent.

Can I use active starter instead of discard?

Discard is better here. Active starter has more gas and yeast activity, which can make the crackers slightly airy and bubbly rather than flat and crisp. Unfed discard keeps things dense and snappy, which is exactly what you want in a cracker.

My scored lines disappeared after baking. What happened?

The lines weren’t scored deeply enough. Go back over them with more pressure before baking — you want visible, defined lines that hold up through the oven. If your pizza cutter doesn’t cut through easily, use a sharp knife instead.
