I have six jars of sourdough discard in my fridge right now. One of them has hooch on top and I have been ignoring it for three days. It is hot out, and just the thought of turning on the oven has me wiping sweat from my brow. This is what sourdough does to a person.
Thankfully, there are many, many ways to make sourdough discard crackers, and they have become a family favorite. The family, admittedly, is my dogs, and they are not all that fussy. Sourdough discard crackers are thin, crispy crackers made from that unfed starter you would otherwise toss, mixed with butter, salt, and a few add-ins, spread thin on parchment, and baked until they snap.
Here is how I make them, plus how I keep them from coming out soft.
What is sourdough discard, and can you make crackers with it?
Discard is the portion of starter you scrape off before feeding so the jar does not overflow. It is just fermented flour and water. I make these crackers when my discard jar is getting full, which, given that I am currently housing six jars, is often.
The best part: crackers do not need the starter bubbly or active. Straight from the fridge, unfed, flat as a forgotten soda, that is exactly what you want. The flavor is mild and tangy, and because discard is already a flour-and-water paste, it spreads and bakes into a cracker beautifully. You are just adding butter for richness, salt for flavor, and whatever add-ins you (or your dogs) are into.
For those of us with six jars in the fridge and zero regrets. Basically my uniform.
What you need to make sourdough discard crackers
A handful of ingredients, and I mix everything before the oven is even on.
How do you make sourdough discard crackers?
This is a spread-and-bake recipe, not a roll-it-out one, which is exactly why I love it on a hot day. Four easy steps.
- Step 1 · Mix. Stir the discard, melted butter, salt, flour (if using), and your cheese, chia seeds, or herbs into a thick, spreadable batter. No mixer, no fuss.
- Step 2 · Spread. Spread it thin and even onto a parchment-lined baking sheet with a spatula, about 1/8 inch (3mm). The thinner and more even it is, the crispier and more evenly it bakes.
- Step 3 · Par-bake, then cut. Bake at 300F (150C) for about 10 minutes, until just set on top. Pull the tray out and run a pizza roller over the whole sheet to cut it into cracker shapes.
- Step 4 · Finish baking. Return the tray to the oven and bake until deeply golden and dry all the way through. It is a lower temperature than a loaf of bread, but about the same total time. Cool completely on the tray, then snap along the lines.
Why aren't my sourdough crackers crispy? A tragedy in three acts
I have made all of these mistakes. Learn from me.
- Act one: spread too thick. The classic, and my usual crime. Spread thinner and more even next time. Thin is the whole game.
- Act two: not baked long enough. Keep going until they are golden and dry all the way through, not just set on top. If a batch is soft in the middle, put it back in for another 10 minutes.
- Act three: stored warm. Trapped steam turns crackers soft overnight. Let them cool completely before they go in a jar. I learned this the sad way.

Flavor variations: choose your fighter
Once you have the base down, the add-ins are a blank canvas. I keep mine dog-friendly, since my taste-testers have four legs. My favorites:
- Cheese. The undisputed household number one. Stir grated cheese right into the batter.
- Fresh herbs. Rosemary is my favorite. Chop it fine and mix it in.
- Chia seeds. Stirred in for a little crunch and some healthy omegas.
How long do sourdough discard crackers last?
In an airtight container at room temperature, they keep about 1 to 2 weeks.
In my house, if the dogs had a say, they would be gone in sixty seconds.
They can hear a cooling rack from three rooms away. If they ever soften, a quick 5 minute trip through a 300F oven brings the snap right back. They also freeze well for up to 3 months, assuming they survive the walk to the freezer, which in my experience they do not.
Frequently asked questions
There's liquid on top of my discard. Is that bad, and do I stir it in?
That liquid is called hooch, and it just means your starter is hungry. It is harmless. Stir it back in for a tangier, more sour flavor, or pour it off first for something milder. Either way, the discard is still perfect for crackers. Yes, this is the exact jar I was stalling on at the top of the post. I stirred it in and moved on.
Can you use unfed sourdough discard for crackers?
Yes. Crackers are the ideal use for unfed discard straight from the fridge. No feeding, no waiting for bubbles, no drama. Flat is exactly what you want.
How long does sourdough discard last in the fridge?
I try to use mine up within about two weeks. A layer of hooch, that grayish liquid on top, can show up within a few days and is completely normal, just stir it back in. But anything showing signs of mold, think fuzz or pink and orange streaks, should be discarded, pun intended, straight into the trash.
Do the crackers need active, bubbly starter?
No. Active starter is for rising bread. Crackers are unleavened, so tired, unfed discard is the hero here.
Can I make sourdough discard crackers gluten-free?
Only if your starter is gluten-free to begin with. A wheat-based discard is not gluten-free. With a gluten-free starter, skip the added flour or use a gluten-free blend, and spread it a touch thicker, as the batter is more delicate.
Because everything from my kitchen is. Even the crackers the dogs stole.
