If you maintain a sourdough starter, you know the guilt of discarding perfectly good starter each week. But what if those discards could become something delicious? Sourdough discard crackers are a simple way to reduce waste while creating an addictive snack that rivals store-bought versions. This recipe transforms that tangy starter into crispy, savory crackers that are perfect for cheese boards, soup toppers, or just snacking straight from the cooling rack.
How to Make Crispy Sourdough Discard Crackers
This straightforward recipe uses common pantry ingredients and basic kitchen equipment. The key is rolling the dough thin and baking it until completely crispy.
Ingredients
- 1 cup active sourdough discard (fed 4-8 hours prior, bubbly and at room temperature)
- 1 1/2 cups all-purpose flour
- 1/4 cup olive oil or melted butter
- 1 teaspoon fine sea salt (plus more for topping)
- 1/2 teaspoon black pepper (or your choice of seasonings: garlic powder, dried herbs, everything bagel seasoning)
- Parchment paper for baking
Method
Mix the dough base
Combine your sourdough discard, flour, olive oil, salt, and pepper in a medium bowl. Stir until a shaggy dough forms, then knead by hand for 2-3 minutes until the mixture comes together into a cohesive ball. The dough should feel slightly tacky but manageable. Let it rest at room temperature for 5 minutes.
Divide and prep work surface
Cut the dough into two equal portions. Line a large baking sheet with parchment paper. This two-batch approach makes rolling and baking much easier than trying to handle one large sheet.
Roll the dough paper-thin
Take one portion and place it between two pieces of parchment paper. Using a rolling pin, roll outward from the center until the dough is as thin as you can make it, ideally 1/8 inch thick or thinner. The thinner you roll, the crispier your crackers will be. You’re aiming for coverage across most of your baking sheet.
Transfer to baking sheet
Carefully peel away the top parchment layer. If using the bottom parchment to transfer, simply slide the dough (still on parchment) onto your prepared baking sheet. If starting fresh, carefully flip and transfer the rolled dough to parchment-lined sheet.
Score and season
Use a sharp knife or pastry wheel to score the thin dough into cracker-sized pieces (roughly 2×2 inches or your preferred size). This makes breaking them apart after baking much cleaner. Sprinkle with your chosen seasonings and press gently so they stick.
Bake until golden and crisp
Place in a 375F oven for 20-25 minutes, or until the crackers are golden brown and feel completely crisp when you touch them. Start checking around 18 minutes, as oven temperatures vary. The edges will brown first; this is fine.
Cool completely on the pan
Remove from oven and let the crackers cool on the baking sheet for at least 10 minutes. This is crucial for developing maximum crispness. Once completely cool, break along the score lines and store in an airtight container.
Repeat with second batch
Repeat steps 3-7 with your second dough portion. Both batches can bake at the same time if your oven has space.
- Use discard that’s freshly fed and bubbly (4-8 hours after feeding) for best rise and flavor. Older discard that’s fallen flat will still work but may be less flavorful.
- Don’t skip the cooling time on the pan. Crackers that seem soft when warm will crisp up significantly as they cool completely.
- Experiment with seasonings: try rosemary and sea salt, cheddar powder, za’atar, everything bagel seasoning, or simple black pepper and garlic.
What to Look For in Sourdough Baking Equipment
- Rolling Pin Material: Marble, wooden, and nonstick rolling pins all work well. Marble stays cool and prevents sticking without flour; wood is traditional and durable; nonstick requires minimal flour. Choose based on your preference and kitchen storage space.
- Parchment Paper Quality: Heavy-duty, silicone-coated parchment resists tearing and handles multiple uses. Unbleached varieties are food-safe and eco-friendly. Look for pre-cut sheets or roll options depending on your baking frequency.
- Baking Sheet Size and Material: Standard half-sheet pans (13×18 inches) are ideal for home bakers. Aluminum conducts heat evenly; steel is more durable. Avoid dark nonstick pans if you prefer lighter browning, as they conduct heat faster.
- Oven Thermometer Accuracy: Many home ovens run hot or cold by 25+ degrees. A reliable oven thermometer ensures your crackers bake at the correct temperature for consistent results and proper crispness.

Frequently Asked Questions
Can I make these crackers without active sourdough discard?
Yes, but the flavor will differ. You can substitute with equal parts flour and water mixed together, though you’ll lose the distinctive tangy sourdough taste. Alternatively, feed your discard 4-8 hours ahead to make it active and bubbly, which provides better texture and flavor than cold discard.
How long do the crackers stay crispy?
Stored in an airtight container at room temperature, homemade sourdough crackers typically stay crispy for 3-5 days. If they soften slightly, you can re-crisp them in a 300F oven for 5-10 minutes. Keep them sealed to prevent moisture absorption.
What seasonings work best?
Sourdough’s tangy flavor pairs well with savory seasonings. Try rosemary and sea salt, everything bagel seasoning, garlic powder and black pepper, Italian herbs, cheddar powder, or za’atar. Avoid wet seasonings like fresh herbs, which add moisture.
Why are my crackers still soft after baking?
This is usually due to insufficient baking time or dough rolled too thick. Check that your oven temperature is accurate with a thermometer, and ensure crackers are completely golden and crisp before removing. They must cool fully on the pan to achieve maximum crispness.
Can I prepare the dough ahead of time?
Yes, you can make the dough up to 8 hours ahead and refrigerate it. When ready to bake, let it sit at room temperature for 15 minutes before rolling. Cold dough is actually easier to roll thin. The longer fermentation may also enhance sourdough flavor.
