Recipe Card: Sourdough Discard Crackers
Prep Time: 10 minutes
Cook Time: 25–30 minutes
Total Time: 40 minutes
Yield: About 60 bite-sized crackers (varies with thickness and scoring)
Ingredients
- 1 cup (240 g) sourdough discard (unfed starter)
- 2 tablespoons (28 g) unsalted butter, melted and cooled slightly
- ½ teaspoon fine sea salt (plus more for sprinkling)
- Optional toppings: sesame seeds, poppy seeds, rosemary, parmesan, chili flakes
Instructions
- Prepare the Baking Sheet
- Preheat oven to 350°F (175°C).
- Line a large baking sheet (13×11 inches or similar) with parchment paper.
- Mix the Batter
- In a bowl, whisk together sourdough discard, melted butter, and salt until smooth.
- Spread Thinly
- Pour the batter onto the parchment-lined sheet.
- Use an offset spatula to spread into an ultra-thin, even rectangle. Aim for nearly transparent coverage for maximum crispness.
- Add Toppings
- Sprinkle chosen toppings evenly across the surface.
- Be light with flaky salt—over-salting is easy since crackers bake thin.
- First Bake & Scoring
- Bake for 10 minutes.
- Remove from oven and lightly score into squares or rectangles with a pizza cutter.
- Final Bake
- Return to oven and bake another 15–20 minutes, until golden and crisp.
- Crackers should sound firm and dry when tapped.
- Cool Completely
- Let crackers cool fully on the baking sheet. This final drying ensures maximum crunch.
- Store Properly
- Keep in an airtight container at room temperature for up to 1 week.
Pro Tips for Success
- Thin is Key – Spread batter almost see-through for the crispiest texture.
- Score Early – After 10 minutes, scoring prevents jagged, uneven pieces later.
- Don’t Skip Cooling – Warm crackers may feel crisp, but cooling ensures long-lasting crunch.
- Avoid Over-Salting – Remember: thin crackers amplify saltiness.
- Refresh If Needed – If crackers soften, bake at 300°F (150°C) for 5–8 minutes.
Variations and Flavor Ideas
One of the best parts about sourdough discard crackers is how adaptable they are. Here are some crowd-pleasing twists:
- Classic Herb Crackers – Add 1 teaspoon dried rosemary or thyme to the batter.
- Cheesy Delight – Mix in ¼ cup finely grated parmesan before baking.
- Spicy Kick – Sprinkle chili flakes or smoked paprika over the top.
- Seed Lover’s Mix – Use sesame, poppy, or sunflower seeds for crunch.
- Mediterranean Vibes – Add oregano and a touch of olive oil for Italian flair.
- Everything Bagel Style – A blend of sesame, onion, garlic, and poppy seeds works beautifully.

Frequently Asked Questions
Q: Can I use active sourdough starter instead of discard?
Yes, but discard provides stronger tang. Active starter will work if that’s what you have on hand.
Q: My crackers aren’t crispy. What went wrong?
They may not have been spread thin enough or baked long enough. You can re-crisp in the oven.
Q: Can I make them gluten-free?
Not with traditional sourdough. You’ll need a gluten-free starter and must experiment with texture.
Q: Can I skip the butter?
Yes—use olive oil or vegan butter. Texture may change slightly but still delicious.
Q: How do I get uniform thickness?
An offset spatula helps spread evenly. Work slowly from center outward.
Troubleshooting Guide
- Too soft? Bake longer or refresh in oven.
- Uneven browning? Rotate baking sheet halfway through.
- Crumbly texture? Batter may have been too thick. Spread thinner next time.
- Overly salty? Use less flaky salt when topping.
