Ingredients

Sourdough discard crackers come together with just three pantry staples plus your choice of seasonings. The discard doesn’t need to be fed or active, which makes this the perfect zero-waste solution for maintaining your starter. Everything gets stirred together in minutes, and you can customize the flavor profile to match whatever you’re serving.
| Group | Ingredient | Amount | Notes |
|---|---|---|---|
| Base | Sourdough discard | 200 grams (1 cup) | Unfed and stirred well |
| Base | Unsalted butter | 2 Tbsp | Melted and slightly cooled |
| Base | Fine sea salt | 1/4 tsp | For the dough itself |
| Toppings | Flaky sea salt | To taste | Maldon or similar works beautifully |
| Toppings | Everything bagel seasoning | Optional | Or sesame seeds, herbs, garlic powder |
Step-by-Step Instructions
Let’s make this happen. Sourdough discard crackers are all about spreading the dough thin and baking until golden and crisp.

Step 1: Preheat and Prep
Preheat your oven to 350°F and line a large baking sheet with parchment paper. Make sure the parchment lies flat without wrinkles so your crackers bake evenly and release easily after cooling.
Step 2: Mix the Dough
Melt the unsalted butter in a large measuring cup or mixing bowl and let it cool to lukewarm so it doesn’t cook the starter. Add your sourdough discard and fine sea salt, then stir everything together with a spatula until the mixture is smooth and fully combined with no streaks of butter.
Step 3: Spread the Dough
Pour the mixture onto your prepared parchment-lined baking sheet. Use an offset spatula to spread it into an ultra-thin, almost transparent layer that measures roughly 13×11 inches. The thinner you spread it, the crispier your crackers will be.
Step 4: Season the Top
Lightly sprinkle the dough with flaky sea salt and your seasonings of choice like everything bagel seasoning, sesame seeds, or dried herbs. Go easy on the salt since the crackers are so thin and can become overly salty quickly.
Step 5: First Bake
Transfer the baking sheet to the oven immediately to prevent the dough from sticking to the parchment. Bake for 10 minutes, then remove from the oven and use a pizza cutter or sharp knife to score the dough into bite-size squares or rectangles.
Step 6: Second Bake
Return the scored crackers to the oven and bake for another 15-20 minutes, or until they’re golden brown and hardened. If the crackers still feel soft when you tap them with your fingernail, continue baking until they’re firm and crisp throughout.
Step 7: Cool and Store
Remove the baking sheet from the oven and let the crackers cool completely on the sheet. This cooling time allows them to dry out fully and reach maximum crunch. Once cooled, break along the scored lines and store in an airtight container or zip bag.
Pro Tips & Gentle Guidance
Sourdough discard crackers are incredibly forgiving, but a few insider tips will help you nail the perfect texture every single time. I’ve made these crackers dozens of times, and these pointers have saved me from soft centers and overly salty bites.
Spread Thinner Than You Think
The single most important factor for crispy crackers is spreading the dough as thin as possible. If you can almost see through the dough in spots, you’re doing it right. Thicker spots will stay soft and chewy instead of crackling when you bite down.
Score Before the Second Bake
Scoring the crackers after the first 10 minutes makes breaking them apart so much easier once they’re fully baked. If you wait until they’re completely done, they’ll shatter into unpredictable shards instead of neat squares.
Watch the Salt Carefully
Because these crackers are so thin, a little salt goes a long way. I learned this the hard way when my first batch tasted like I’d licked the ocean. A light sprinkle of flaky salt is all you need for perfect seasoning.
Let Them Cool Completely
I know it’s tempting to grab a cracker right out of the oven, but they need that cooling time to finish crisping up. Warm crackers will feel softer than they really are, and they’ll harden beautifully as they cool on the baking sheet.
Customize Your Flavors
Once you’ve nailed the basic recipe, try adding garlic powder, dried rosemary, smoked paprika, or grated Parmesan to the dough itself. According to The Kitchn’s guide on using sourdough discard, mixing seasonings into the dough distributes flavor more evenly than just topping.
Variations & Adaptations
The beauty of sourdough discard crackers is how easily they adapt to whatever flavors you’re craving. Here are some of my favorite twists that keep things exciting batch after batch.
Everything Bagel Crackers
Top the dough generously with everything bagel seasoning before baking for a savory, sesame-forward cracker that’s perfect with cream cheese. These are dangerously addictive and disappear faster than plain versions.
Herb and Garlic Crackers
Mix 1 teaspoon of dried Italian herbs and 1/2 teaspoon of garlic powder directly into the dough before spreading. These pair beautifully with marinara sauce for dipping or alongside a big Italian salad.
Cheesy Sourdough Crackers
Stir 1/4 cup of finely grated Parmesan or aged cheddar into the dough for rich, umami-packed crackers. The cheese adds extra flavor and helps the crackers brown even more beautifully.
Sweet Cinnamon Sugar Version
Omit the salt and top the dough with a mixture of cinnamon and granulated sugar for a sweet twist. These work wonderfully with tea or coffee and feel like a little afternoon treat.
Spicy Crackers
Add 1/4 teaspoon of cayenne pepper or red pepper flakes to the dough for a gentle kick. Top with smoked paprika and flaky salt for crackers that pair perfectly with hummus or guacamole.
Quick Fixes for Sourdough Discard Crackers
Problem: Crackers are still soft in the center
This usually means the dough wasn’t spread thinly enough or the crackers need more baking time. Pop them back in the oven for another 5 minutes and check for firmness by tapping with your fingernail.
Problem: Crackers are burning around the edges
Your oven may run hot or the dough thickness is uneven. Try lowering the temperature to 325°F and spreading more carefully, or rotate the baking sheet halfway through the second bake for more even browning.
Problem: Crackers are too salty
Because these crackers are so thin, it’s easy to over-salt them. Next time, use a lighter hand with the flaky salt topping and taste a small piece before seasoning the whole batch.
Problem: Dough is sticking to the parchment
Make sure you transfer the baking sheet to the oven immediately after spreading and topping. If the dough sits too long, it can bond with the parchment and become difficult to remove.
Problem: Crackers aren’t crispy after cooling
This likely means there’s still moisture trapped in the crackers. Spread them on a baking sheet and return to a 300°F oven for 5-10 minutes to dry them out completely.
Storage & Reheating

Sourdough discard crackers stay crispy and delicious when stored properly, and they’re versatile enough to serve alongside almost any meal or snack. These crackers are best enjoyed at room temperature where their crunch really shines.
Store cooled crackers in an airtight container or resealable plastic bag at room temperature for up to one week. If they lose their crispness, you can refresh them by spreading on a baking sheet and warming in a 300°F oven for 3-5 minutes.
These crackers don’t freeze particularly well since the texture can become softer when thawed, but they’re so quick to make that you can easily whip up a fresh batch whenever you need them. Serve them on cheese boards, alongside soups like my favorite cozy sourdough recipes, or just snack on them straight from the container.
| Storage Method | Duration | Best For |
|---|---|---|
| Room temperature (airtight container) | Up to 1 week | Maximum crispness |
| Refrigerator (airtight container) | Up to 2 weeks | Extending shelf life (may soften slightly) |
| Freezer | Not recommended | Texture suffers when thawed |
| Re-crisping in oven | 3-5 minutes at 300°F | Reviving soft crackers |

No-Waste Kitchen Magic
Making sourdough discard crackers is already a zero-waste win, but you can stretch that philosophy even further with these creative tips. Every bit of your ingredients can shine when you think creatively.
Save Your Cracker Crumbs
Any broken bits or crumbs make an incredible topping for salads or soups. I toss mine with olive oil and use them as a crunchy garnish for tomato soup or creamy pasta dishes.
Use Browned Butter
Instead of just melting the butter, brown it slightly for a nutty, caramelized flavor that adds depth to your crackers. Let it cool before mixing with the discard so it doesn’t cook the starter.
Incorporate Herb Stems
If you’ve been saving herb stems from parsley, cilantro, or basil, mince them finely and mix them into the dough. They add flavor without any waste and a lovely green fleck throughout the crackers.
Repurpose Stale Crackers
If your crackers somehow get stale or soft, pulse them in a food processor to make flavored breadcrumbs. Use them to coat chicken, top casseroles, or add crunch to baked mac and cheese.
Make Flavored Salt Blends
Mix your flaky salt with dried herbs, citrus zest, or spices and keep it in a jar for topping future batches. It’s a simple way to add variety without buying multiple seasoning blends.
Frequently Asked Questions
Here are answers to the most common questions about making sourdough discard crackers at home.
What is sourdough discard and can I use it for crackers?
Sourdough discard is the portion of sourdough starter that you remove during regular feedings. It is perfectly suitable for making crackers and provides a tangy flavor and crispy texture. Using discard in crackers is an excellent way to reduce food waste while creating a delicious snack.
How long do sourdough discard crackers stay fresh?
When stored in an airtight container at room temperature, sourdough discard crackers will stay fresh and crispy for up to two weeks. Make sure they are completely cooled before storing to prevent moisture buildup. If they lose their crispness, you can refresh them in a low oven for a few minutes.
Do I need to use unfed or fed sourdough starter for crackers?
You can use either unfed discard or recently fed starter for making crackers. Unfed discard works perfectly well and is actually preferred since it helps reduce waste. The fermentation level does not significantly impact the final texture of the crackers, though unfed discard may provide a more pronounced tangy flavor.
What seasonings work best for sourdough discard crackers?
Popular seasonings include sea salt, rosemary, garlic powder, dried herbs, sesame seeds, everything bagel seasoning, black pepper, and parmesan cheese. You can customize the flavor to your preference by adding seasonings to the dough or sprinkling them on top before baking. Both savory and slightly sweet variations work well.
Why are my sourdough discard crackers not crispy?
Crackers may not be crispy if they are rolled too thick, not baked long enough, or stored before completely cooling. For best results, roll the dough very thin, bake until the edges are golden brown, and allow crackers to cool completely on the baking sheet. If needed, return them to a low oven to dry out further.
Final Dish
These sourdough discard crackers have become one of my go-to recipes when I need a quick, impressive snack that makes me feel like a kitchen rockstar. They’re proof that zero-waste cooking doesn’t have to be complicated or time-consuming, and they turn something you’d normally toss into a crunchy, flavorful treat everyone loves.
