Sourdough Discard Crackers That’ll Make You Stop Tossing That Jar

I used to dump my sourdough discard straight into the trash every single week and just… feel bad about it.

That jar sat on my counter, quietly growing, and every feeding meant scraping out a cup of tangy, bubbly starter that had nowhere to go. It felt wasteful. It also felt like a problem I was too tired to solve.

Then Silas asked me a question that changed everything: “Why don’t you just make crackers with it?”

I looked at him like he’d suggested I bake with sand. But I tried it that same afternoon, and I haven’t thrown out discard since.

These crackers are crispy, a little tangy, and dangerously easy to snack straight off the baking sheet. 🧀 They taste like something you’d pay eight dollars for at a fancy cheese shop, except you made them with stuff that was headed for the compost bin.

Let’s get into it.

What You’ll Need

Here’s everything you’ll be pulling out for this one.

Ingredients:

  • 1 cup unfed sourdough discard (straight from the fridge is fine)
  • 4 tablespoons unsalted butter, melted and cooled slightly
  • 1 teaspoon fine sea salt, plus extra for topping
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1 tablespoon olive oil (for brushing)
  • Optional: everything bagel seasoning, flaky salt, dried herbs, or grated parmesan for topping

Tools:

  • Mixing bowl
  • Rubber spatula
  • Rolling pin
  • Parchment paper
  • Baking sheet
  • Pizza cutter or sharp knife
  • Fork (for docking the dough)

That’s it. No stand mixer, no fancy equipment, nothing you need to special order.

Pro Tips

A few things I learned the hard way so you don’t have to.

  1. Roll it thin. Then roll it thinner. If your dough is even slightly thick, the middle of each cracker stays chewy instead of crisp. You’re aiming for something close to the thickness of a nickel.
  2. Don’t skip docking the dough. Poking holes all over with a fork before baking keeps the crackers from puffing up into little pillows. Flat crackers, happy snacker.
  3. Use discard, not fed starter. Fed starter has extra flour and water in it that throws off the texture. Straight discard, ideally a few days old, works best here.
  4. Score before baking, not after. Cut your cracker lines with a pizza cutter before the sheet goes in the oven. Trying to snap them apart after baking just shatters everything.
  5. Watch the edges, not the clock. Ovens vary a lot, and these can go from golden to burnt fast in the last two minutes. Pull them the second the edges turn deep gold.

How to Make Sourdough Discard Crackers

Step 1: Mix the dough

In your mixing bowl, combine the sourdough discard, melted butter, salt, garlic powder, and onion powder. Stir with your rubber spatula until it comes together into a shaggy, slightly sticky dough.

It won’t look like much at this stage. That’s normal.

Step 2: Rest the dough

Cover the bowl and let it sit at room temperature for 20 to 30 minutes. This makes it much easier to roll out and helps the flavors settle in.

Step 3: Roll it out

Preheat your oven to 350°F (175°C).

Place the dough between two sheets of parchment paper. Roll it out as thin as you possibly can, aiming for about 1/16 of an inch. Thin is the whole game here.

Step 4: Cut and dock

Peel off the top parchment sheet. Use your pizza cutter to slice the dough into whatever shape you like (squares are classic, but I’ve done triangles too).

Grab your fork and poke each cracker a few times. This stops them from bubbling up in the oven.

Step 5: Season the top

Brush the surface lightly with olive oil, then sprinkle on your salt and any extra toppings you’re using. Press gently so they stick.

Step 6: Bake

Slide the parchment (dough and all) onto your baking sheet. Bake for 15 to 20 minutes, checking often after the 12-minute mark.

Pull them out once the edges are deep golden brown.

Step 7: Cool completely

Let the crackers cool fully on the baking sheet before breaking them apart along your score lines. They’ll crisp up even more as they cool, so don’t skip this step no matter how good your kitchen smells right now.

Substitutions and Variations

Garlic powderFresh minced garlicUse sparingly, about 1 teaspoon, can burn faster
Plain crackersEverything bagel versionAdd 1 tablespoon everything seasoning to the dough itself
Salted crackersSweet versionSkip garlic and onion powder, add 1 tablespoon honey and cinnamon

You can also fold in finely grated parmesan, chopped rosemary, or even a pinch of chili flakes right into the dough before rolling.

Make Ahead Tips

The dough can be made up to 3 days ahead and kept covered in the fridge. Let it sit at room temperature for about 15 minutes before rolling so it’s not too stiff.

You can also freeze the rolled, unbaked dough sheets between layers of parchment for up to a month. Bake straight from frozen, just add a couple extra minutes.

Meal Pairing Suggestions

These crackers were basically made for a cheese board. A few pairings I keep coming back to:

  • Sharp cheddar and fig jam for something sweet and savory
  • Whipped goat cheese and honey if you want it fancier
  • Hummus and cucumber for a lighter, fresher bite
  • Tomato soup for dunking on a cold day

Storage and Leftovers

Store the fully cooled crackers in an airtight container at room temperature. They’ll stay crisp for up to a week.

If they lose their crunch (usually from humidity), pop them back in a 300°F oven for 5 minutes to re-crisp.

Freezing baked crackers isn’t ideal since they tend to go soft when thawed, but the raw dough freezes beautifully if you want a make-ahead option.

FAQ

Can I use active, fed sourdough starter instead of discard? You can, but the texture changes. Fed starter has more moisture and less acidity, so your crackers may puff slightly more and taste less tangy.

Why did my crackers turn out chewy instead of crisp? Almost always a rolling issue. If any part of the dough is thicker than a nickel, that section won’t fully crisp up in the oven.

Can I make these gluten-free? Not with a traditional wheat-based sourdough discard. If you keep a gluten-free starter, the same method should work, though baking time may vary slightly.

Do I need to refrigerate the dough before baking? No, a short 20 to 30 minute rest at room temperature is all you need. Chilling isn’t necessary for this recipe.

How thin is too thin? Honestly, thinner is almost always better here. As long as you can transfer the dough without it tearing apart, you’re fine.

Wrapping Up

That jar of discard sitting in your fridge right now? It’s basically a bag of free crackers waiting to happen.

This recipe turned one of my most annoying kitchen habits into one of my favorite snacks, and I have a feeling it’s about to do the same for you.

Give these a try this week and let me know how they turn out in the comments below. I’d love to hear what toppings you went with, and if you run into any questions along the way, just ask. I read every comment. 🍽️
