A Love Letter to Discard

I didn’t always love sourdough discard. In fact, I used to feel a little guilty watching it swirl down the sink after feedings. But that changed one quiet Sunday in West Lafayette. I had just refreshed my starter and stared at the extra cup of discard sitting on the counter. Instead of tossing it, I mixed it with some flour, olive oil, salt and made crackers. That one spontaneous decision sparked a weekly ritual I now look forward to.

Hi, I’m Emily Truett, and in my kitchen, we believe no bit of dough should go to waste. These crackers were my turning point. The day discard stopped being something I had to deal with and became something I loved to use. Every batch feels like a small win. No waste, lots of flavor, and a tray of something homemade and snack-worthy.

The first version was simple. I scored the dough into triangles, sprinkled flaky salt, and baked until golden. They came out crisp, rustic, and just a little tangy. Pure sourdough magic. Over time, I started experimenting. Some days I go herby, like in these garlic herb crackers or try a fragrant rosemary sea salt variation. The base is endlessly adaptable, just like your discard.

If you’ve ever looked at your jar of discard and thought, “I should do something with this,” then this recipe is for you. It’s forgiving, fast, and gives you something genuinely craveable. You’ll be amazed how crisp they bake up. No fancy ingredients, just pantry basics. And if you’re new to sourdough entirely, don’t worry. I’ve got a starter tutorial that’ll get you going in no time.

And let me tell you, these aren’t just snacks. I serve them with jalapeño popper bites at gatherings, pack them next to energy bites for hikes, or crumble them into soup. They also disappear fast, so double the batch if you’re feeding more than two.

Still tossing your discard? You won’t be after this. Let’s turn that tangy byproduct into something you’ll actually crave.

Your Foolproof Guide to Sourdough Discard Crackers

The Essential Ingredients for Texture and Flavor

The beauty of learning how to make sourdough discard crackers lies in the simplicity of the ingredient list. You don’t need special tools or fancy flour blends. What you need is probably already in your pantry and fridge.

The key player here is the sourdough discard. Unfed and cold from the fridge works just fine. It brings a slightly tangy flavor and helps with that perfect crisp finish. Mix it with all-purpose flour to create a pliable dough that rolls thin. Olive oil adds richness, while sea salt brings balance.

Want to elevate the flavor? You can add a pinch of garlic powder, dried rosemary, or thyme. I sometimes go bold with everything bagel seasoning or a sprinkle of parmesan. If you’re experimenting, take a peek at my sourdough cheesy breadsticks for flavor combo ideas. Or get inspired by the sweet side of discard in these cinnamon sugar crisps.

Here’s what you’ll need:

Ingredient	Purpose
1 cup sourdough discard	Tangy base, hydration, and depth
1 cup all-purpose flour	Structure and crispness
1/4 cup olive oil	Flavor and tender texture
1/2 tsp sea salt	Seasoning
Optional: herbs or garlic powder	Boost flavor

You can double or halve this recipe easily. Just be sure to keep the dough thin before baking for the crisp factor.

The Simple Steps to Golden Perfection

Ready to bake? Start by preheating your oven to 325°F (160°C) and lining a sheet pan with parchment paper. This helps prevent sticking and ensures even browning. In a medium bowl, mix the sourdough discard, flour, olive oil, salt, and any flavor additions you’re using.

Use your hands to knead the dough gently until it comes together. If it’s sticky, sprinkle in a little more flour. Now comes the most important step—rolling the dough thin. Place it between two sheets of parchment paper and roll it out until it’s almost transparent. Thin dough equals crispy crackers.

Score the dough with a knife or pizza cutter into your desired shapes. Squares, triangles, or irregular rustic cuts all work beautifully. Sprinkle flaky salt on top if desired.

Bake for 20 to 25 minutes. Keep an eye on them in the last five minutes—they go from golden to too-dark quickly. You’re looking for edges that are golden brown and a center that feels firm.

Let the crackers cool completely on the pan or a wire rack. They crisp up more as they cool. Don’t skip this step. That cool-down is where the crunch develops.

Once you make these once, they’ll become part of your baking routine. The method is easy, the ingredients flexible, and the results consistently addictive.

Flavor Variations to Try

Savory Twists: Cheese, Herbs, and Spice

Once you’ve mastered the base recipe, it’s time to explore. One of the best parts about learning how to make sourdough discard crackers is how endlessly adaptable they are. Want bold flavor? Add finely shredded parmesan or cheddar to the dough. Prefer something earthy? Dried rosemary, thyme, or crushed fennel seeds bring a beautiful herbal note. If you’re a garlic lover, garlic powder or roasted garlic paste mixed into the dough is absolutely next-level.

Another favorite in our home is cracked black pepper with a touch of smoked paprika. It gives the crackers a subtle kick and gorgeous color. If you enjoy spice, sprinkle chili flakes over the top before baking.

Craving that salty, savory crunch found in store-bought snack mixes? A sprinkle of everything bagel seasoning adds punch and texture. You can even use a mix of white and whole wheat flour for a heartier, nuttier flavor profile. That’s the same blend I use in my soft sourdough discard naan for added complexity.

To get a flaky cheese crust, press grated cheese directly onto the surface of your scored dough before baking. It caramelizes and gives the crackers irresistible edges.

Sweet Crackers: Yes, It Works

Most people don’t think sweet when they learn how to make sourdough discard crackers, but trust me it’s a revelation. Try adding a tablespoon of maple syrup or honey to your dough for a subtle sweetness that pairs beautifully with soft cheeses or nut butters.

Cinnamon sugar is a game-changer. Roll the dough thin, brush with melted butter, then sprinkle cinnamon and raw sugar over the top before scoring and baking. The result is a crisp, toasty cracker with a sweet, tangy finish. It’s inspired by my popular cinnamon sugar crisps, which readers love for holiday snack boards.

You can even go slightly decadent with cocoa powder and a pinch of espresso powder for chocolate dessert crackers that pair well with fresh berries or whipped ricotta.

Fruit lovers might try folding finely chopped dried cranberries or apricots into the dough. A sprinkle of flaky sea salt on top balances the sweetness and brings out the natural sourdough flavor.

These sweet variations aren’t just for dessert trays. They’re perfect for brunch boards or as a mid-afternoon treat. Think of them as a grown-up cookie with tang and crunch.

The base recipe gives you a strong starting point. From there, it’s easy to follow your cravings and create something truly unique. You’ll quickly see why this is one of the most versatile ways to bake with discard.

Storage, Pairing & Troubleshooting

How to Keep Crackers Crisp for Days

After you’ve learned how to make sourdough discard crackers, the last thing you want is for them to go soft. Luckily, crispness is easy to preserve with the right storage.

First, make sure your crackers cool completely before storing. Any warmth left in them will create condensation, and moisture is the enemy of crunch. Once cooled, place the crackers in an airtight container with a small piece of parchment or wax paper inside to absorb excess air moisture.

Store the container in a cool, dry place away from sunlight. Avoid refrigerating them—fridge air tends to rehydrate baked goods and dull their texture. If you’re storing them for more than a week, a resealable glass jar works best.

Want to keep things extra fresh? Add a food-safe silica packet, like the kind that comes in nori or jerky packages. It’s a trick I also use for my sourdough discard biscuits when storing longer term.

If your crackers do lose crispness, you can bring them back. Preheat the oven to 300°F, lay the crackers in a single layer on a sheet pan, and bake for 5–7 minutes. Let them cool completely, and you’ll get most of that crunch back.

Why Are My Crackers Soft or Chewy?

Even experienced bakers run into this. If your crackers aren’t crisp, the dough was likely too thick or the baking time too short. Roll it out thinner next time. You’re aiming for almost transparent dough before scoring and baking.

Also check your oven temperature. Ovens vary, and an oven thermometer helps ensure you’re really hitting that 325°F mark. If the heat’s too low, the crackers will dry slowly and stay chewy rather than crisp.

Humidity can also play a part, especially in summer. If you live in a damp climate, shorten your storage time or add a re-crisping bake before serving.

Finally, pay attention to your discard. If it’s too runny, your dough may be too wet. Mix in just enough flour to create a soft, pliable dough that doesn’t stick. That balance is crucial for structure and crunch.
