Pin it My sourdough starter had been sitting neglected in the back of my fridge for weeks, and I kept feeling guilty about all that discard I was throwing away. One afternoon, while snacking on a box of store-bought cheese crackers that tasted like cardboard, it hit me: why not turn that tangy starter into something crispy and golden? The first batch came out almost by accident, but the moment I bit into one and got that perfect combination of buttery crunch and sharp cheddar with a whisper of sourdough funk, I knew I'd stumbled onto something special.
I brought a batch to a potluck last spring, and they disappeared faster than the fancy dip everyone brought. My neighbor actually asked for the recipe with this look of genuine desperation, and I realized these weren't just a way to use up starter—they'd become the thing people actually asked me to make. Now whenever someone visits, these crackers are the first thing I pull out, and somehow the conversation always starts with someone reaching for another handful.
Ingredients
- All-purpose flour: This is your structure, the foundation that holds everything together—don't skip it or substitute with whole wheat without adjusting your liquids.
- Sharp cheddar cheese, finely shredded: The sharper the better; it's what gives these their personality and that intense, savory punch that makes them impossible to stop eating.
- Unsalted butter, cold and cubed: Cold butter creates those delicate layers and flakes—if it's warm, you'll end up with dense, tough crackers instead of crispy ones.
- Sourdough starter discard: Use the unfed, slightly separated kind that's been sitting in your fridge; it brings that subtle tang that makes people wonder what your secret ingredient is.
- Salt, garlic powder, onion powder: These season the dough itself, so every cracker has flavor baked into it, not just on top.
- Everything bagel seasoning: This is your personality layer—those sesame seeds and poppy seeds add texture and visual appeal that makes people pick one up before they even know what it is.
- Flaky sea salt: Don't use table salt for the topping; the larger crystals dissolve slower and give you those satisfying crunchy moments.
- Olive oil for brushing: This helps the seasoning stick and gives the crackers that gorgeous golden color and extra crispness.

Instructions
- Build your base in the food processor:
- Pulse the flour, cheddar, cold butter, salt, garlic, and onion powder until it looks like coarse breadcrumbs with tiny butter pebbles still visible. This texture is crucial—those little butter pieces are what'll make your crackers flaky.
- Bring the dough together:
- Add your sourdough discard and pulse just until a shaggy dough forms; don't overwork it or you'll toughen the final crackers. You're looking for something that just barely holds together when you squeeze it.
- Knead and rest:
- Turn it onto a lightly floured surface and knead for maybe thirty seconds—just enough to bring it together smoothly. Divide in half, flatten into disks, wrap, and slide into the fridge for at least thirty minutes while you get everything else ready.
- Prep your workspace:
- Heat your oven to 350°F and line two baking sheets with parchment paper. Having everything ready before you start rolling makes the whole process feel less chaotic.
- Roll thin and even:
- Working with one dough disk at a time, roll it between two sheets of parchment to about an eighth of an inch thick—this is thinner than you'd expect, but it's what gives you that snap. If your dough keeps springing back, let it rest for a few minutes and try again.
- Oil and season generously:
- Brush the surface lightly with olive oil and sprinkle the everything seasoning and flaky salt evenly across the whole thing. The oil acts like glue, keeping all those seeds and flavors from sliding off during baking.
- Cut with confidence:
- Use a pizza cutter or sharp knife to cut one-inch squares, and space them just barely apart on your baking sheets. They won't spread much, but a tiny gap keeps them from steaming into each other.
- Bake until golden:
- Bake for 16 to 18 minutes, rotating the pans halfway through so they brown evenly. You're looking for a golden color, not dark brown—pull them out when they're still just slightly soft in the center because they'll crisp up as they cool.
- Cool completely:
- Spread them on a wire rack and let them cool all the way down before eating or storing. This is where the final crunch develops, so be patient even though they smell incredible.
Pin it There's something magical about sitting down with a cup of coffee and a small pile of these crackers on a quiet morning, the house still asleep. They've become my thing to make when I want to feel like I've accomplished something delicious without spending my whole day in the kitchen.
Why Sourdough Discard Is Your Secret Weapon
Most people think sourdough discard is waste, but it's actually liquid gold for crackers. It brings a subtle tang that plays beautifully with the sharp cheddar, and it already has just enough fermentation to give the dough character without any extra effort on your part. The acidity also helps everything brown faster and more evenly, so your crackers come out with that perfect even golden color every time.
Customizing Your Seasoning
While everything bagel seasoning is perfect, I've experimented with so many different flavor combinations over the months. Sometimes I'll mix in fresh cracked black pepper, or swap the everything for a cajun seasoning blend, or even add a tiny pinch of smoked paprika for something completely different. The formula stays the same—it's really just about playing with what excites you in that moment.
Storage and Keeping Them Crispy
These crackers actually stay crispy for days if you store them properly in an airtight container, and they'll taste almost as fresh on day three as they do still-warm from the oven. I've learned the hard way that humidity is the enemy, so if you're in a damp climate, a small silica packet in the container works wonders for keeping them from getting soft.
- Make these ahead for parties or weeknight snacking without the last-minute stress.
- If they do go soft, crisp them up in a 300°F oven for five minutes before serving.
- Double the batch because one always disappears before you even realize you've eaten it.
Pin it These crackers are proof that the best recipes often come from trying to solve a small problem—in this case, what to do with all that sourdough discard sitting in my fridge. Now they're something I make regularly, and I genuinely look forward to those quiet moments when the kitchen smells like baking cheese and butter.
