If you maintain a sourdough starter, you know the guilt of discarding perfectly good culture each week. Instead of watching it go to waste, turn that discard into restaurant-quality olive oil crackers that are salty, crispy, and impossible to stop eating. This recipe uses basic pantry staples and requires minimal equipment, making it perfect for both sourdough veterans and curious beginners looking to reduce kitchen waste.
How to Make Sourdough Discard Olive Oil Crackers
These crackers come together in about 30 minutes of active time, with most of the work happening in the oven. The dough is forgiving and doesn’t require bulk fermentation or shaping skills.
Ingredients
- 1 cup sourdough discard (unfed starter at room temperature)
- 3 tablespoons extra virgin olive oil, plus more for brushing
- 1 teaspoon fine sea salt, plus fleur de sel for topping
- 1/2 teaspoon cracked black pepper
- 1/2 teaspoon garlic powder or Italian seasoning (optional but recommended)
- 1/2 cup all-purpose flour
Method
Combine wet ingredients
Pour your sourdough discard into a medium mixing bowl. Add the olive oil and stir until well combined. The mixture should feel loose and slightly sticky at this stage. This creates an emulsion that keeps the crackers tender inside while crisping the edges.
Mix in seasonings and flour
Sprinkle the salt, black pepper, and garlic powder (if using) over the wet mixture. Add the flour gradually, stirring with a wooden spoon until a shaggy dough forms. Don’t overmix; you’re aiming for a dough that just comes together, not a perfectly smooth ball.
Prepare your baking surface
Line a large baking sheet with parchment paper. Lightly flour the parchment to prevent sticking. If you prefer thinner, crispier crackers, use two baking sheets to avoid crowding, which can cause uneven baking and steaming.
Roll out the dough thin
Transfer the dough onto the prepared parchment. Using a rolling pin or even a measuring cup, roll the dough into a thin, even layer about 1/8 inch thick. Thinner dough yields crispier crackers, while slightly thicker dough will have more chew. Work gently to avoid tearing.
Score and season
While the dough is still on the sheet, use a sharp knife or pastry cutter to score the dough into cracker-sized squares or diamonds. Don’t cut all the way through; just indent the surface so they break apart cleanly after baking. Lightly brush the top with olive oil and sprinkle generously with fleur de sel or coarse sea salt.
Bake until golden and crispy
Bake at 350 degrees Fahrenheit for 15 to 20 minutes, until the edges are deep golden brown and the center is light golden. Start checking at 12 minutes, as oven temperatures vary. The crackers will crisp up further as they cool, so don’t overbake to the point of darkening.
Cool completely before breaking
Remove the sheet from the oven and let the crackers cool for 5 minutes on the pan. They will continue to firm up. Once completely cool (about 10 minutes), break along the scored lines. For maximum crispness, transfer to a wire rack for the final cooling phase.
Store for maximum freshness
Place cooled crackers in an airtight container at room temperature. They will stay crispy for up to one week. For longer storage, freeze them in a freezer bag for up to one month. Refresh slightly-staled crackers by placing them on a baking sheet and warming at 300 degrees for 3 to 5 minutes.
- For extra flavor, add 2 tablespoons grated Parmesan cheese or 1 teaspoon fresh rosemary to the dough before rolling.
- If your discard is very thick, thin it slightly with a tablespoon of water before mixing to achieve the right dough consistency.
- Rotate the baking sheet halfway through cooking if you notice uneven browning, which is common with home ovens.
What to Look For in Crackers-Making Equipment
- Rolling pin weight and material: A heavier rolling pin distributes pressure evenly and requires less arm strength, making thin, uniform crackers easier to achieve. Marble or stainless steel pins maintain cool temperatures and resist sticking better than wood.
- Parchment paper quality: High-temperature parchment prevents crackers from sticking and browning unevenly. Look for silicone-coated varieties rated to at least 420 degrees Fahrenheit for reliability across different ovens.
- Baking sheet heat distribution: Aluminum or steel sheets with medium thickness provide even heat. Avoid thin, flimsy sheets that warp and cause hot spots; premium half-sheet pans bake crackers more consistently.
- Sharp cutting tool precision: A pizza cutter or pastry wheel scores the dough cleanly without dragging, while a sharp chef’s knife creates precise fracture lines. Dull tools tear the dough and prevent clean breaks.

Frequently Asked Questions
Can I use fed sourdough starter instead of discard?
Yes, but the flavor will be milder. Fed starter contains active yeast, which may cause slight puffing during baking. Use the same measurement and expect crackers to be slightly less crispy. Discard works best because it’s dormant and yields maximum crispness.
What if my dough tears while rolling?
Pinch the torn edges together gently; the oil in the dough acts as a sealant. If tears persist, let the dough rest 5 minutes to relax the gluten. Ensure your rolling pin isn’t too cold, which can make dough brittle. Slightly warmer dough is more forgiving.
How do I know when crackers are done baking?
The edges should be deep golden brown and crisp, while the center is light golden. Remove them when they look slightly underbaked; they’ll crisp up as they cool. Overbaking makes them bitter and hard, so start checking at 12 minutes.
Can I add herbs or cheese to the dough?
Absolutely. Add 1 to 2 tablespoons of fresh or dried herbs like rosemary, thyme, or oregano, or 2 to 3 tablespoons grated Parmesan before rolling. Keep total additions under 3 tablespoons to avoid changing the dough structure.
Why are my crackers chewy instead of crispy?
Chewy crackers indicate insufficient drying. Either your dough was too thick, your oven temperature too low, or you removed them too early. Roll thinner next time, verify your oven temperature with a thermometer, and bake until edges are truly golden. Cool completely before storing to retain crispness.
