If you have sourdough discard sitting in your fridge right now, you are twenty-five minutes away from a batch of crackers.
That’s it. That’s the whole pitch.
No waiting. No activating your starter. No planning ahead. Pull the jar out of the fridge, mix in two more things, and spread it on a pan.
These are thin, crispy, snacking crackers — the kind you grab off the counter between chores without really meaning to. Light enough for hummus or a soft cheese. Not built for heavy toppings. Just honest, simple crackers made from something that would have otherwise gone down the drain.
The edges shatter when you bite them, the centers stay crisp, and the salt catches first before the sourdough tang comes through.
We are an ingredients household. I don’t buy a lot of processed foods — potato chips don’t make the shopping list. These crackers fill that gap. Thin, crispy, made from three things I can name. That matters to me.
They’re mostly mine. But they never last long enough to prove it.
What You Need
This is genuinely a 3-ingredient recipe. No baking powder, no flour, no eggs, no butter. Just:
- 1 cup sourdough discard
- 2 tablespoons olive oil
- Flaky salt for the top — Diamond Crystal or Maldon
That’s it. If your discard jar is in the fridge right now, you already have everything you need.
What Kind of Discard Works Here
Here’s the thing most sourdough recipes don’t tell you: you can use your discard cold, straight from the fridge.
No need to bring it to room temperature. No need to feed it first. If it’s been sitting unfed for a few days, that’s fine — the slightly more sour discard actually adds better flavor to these crackers. Use it as-is.
The only thing to check: your discard should be pourable. If it’s stiff and thick, it’s been in the fridge a long time and may have thickened up. A quick stir usually fixes it. If it’s very liquid and separated with a lot of hooch on top, just stir that back in — it’s still good.
Room temperature discard works too. Either way produces good crackers. Cold just means you don’t have to plan ahead at all.
How to Make Homemade Sourdough Crackers
Mix
Combine the discard and olive oil in a bowl and stir until fully mixed. The batter will be thin — thinner than pancake batter. That’s correct.
No resting time needed. Mix and go straight to spreading.
Spread
Line a large sheet pan with parchment paper. Pour the batter onto the parchment and spread it as thin as you can — aim for an even layer, roughly 1/8 inch or less. Thinner means crispier. If you have a small offset spatula, use it. A regular spatula or the back of a spoon works too.
The batter will spread easily. Don’t worry about getting it perfectly even — slight variation in thickness gives you crackers with a little texture variety, some extra-crispy edges.
Sprinkle flaky salt over the top before it goes in the oven.
Bake
325°F for 25-35 minutes total.
At the halfway mark — roughly 12-15 minutes in — pull the pan and score the crackers.
Use a pastry wheel, pizza cutter or sharp knife to score them into whatever size you like. Rectangles, squares, random shapes — it doesn’t matter. Scoring while partially baked (rather than before or after) gives you clean break lines without cracking the finished crackers.
Sometimes at this point, I like to drizzle a little more olive oil and salt before they go back into the oven for the final bake. It’s not required. It’s just good.
Return to the oven for the remaining time. If you want a little golden color, a quick minute under the broil at the very end does it. I do this when friends join us in the Grain Shed, our back yard pub — it makes them look like you tried harder than you did.
How to Know They’re Done
The edges will be golden and the surface will look dry and set. The crackers should feel firm — not soft or bendable — when you touch the center. They’ll continue to crisp slightly as they cool.
If the edges are browning faster than the center, your oven runs hot. Drop to 310°F next time or pull them a few minutes early.
Let cool completely on the pan before breaking apart. They crisp up fully as they cool — don’t judge them straight from the oven.
What to Expect
These are thin, delicate, snacking crackers. Here’s what normal looks like:
Texture: Crispy and light with a slight tang from the discard. Not sturdy — these are not a vehicle for heavy toppings. Think soft cheese, a light dip, or just plain snacking.
Flavor: Mildly sour, savory from the salt, with a subtle richness from the olive oil. The more sour your discard, the more pronounced the tang.
Yield: One cup of discard on a standard half-sheet pan makes enough crackers to fill a medium bowl — roughly 30-40 crackers depending on how you score them.
Storage: Once completely cool, store in an airtight container at room temperature. Best within 3-4 days, though they rarely last that long.
Why This Works
Sourdough discard is mostly flour and water in a fermented slurry. When you spread it thin and bake it low and slow, the water evaporates, the fermented starches crisp up, and you get a cracker with built-in structure — no added flour needed.
The olive oil adds richness and helps with browning. The low temperature (325°F) gives the moisture time to escape evenly before the outside sets, which is why you get a crisp cracker instead of a brittle, uneven one.
Scoring halfway through works because the batter has set enough to hold a score line but hasn’t hardened yet — so the knife moves cleanly rather than cracking or dragging.
Troubleshooting
Crackers are soft in the middle after cooling.They weren’t baked long enough. Return to a 300°F oven for another 8-10 minutes. Low and slow is better than high heat to finish them — you want to drive out moisture, not burn the edges.
Crackers are sticking to the parchment.Parchment shouldn’t stick, but if it does, let them cool completely first — they release more easily once fully cooled and crisp.
Edges are burning before the center is done.Your batter wasn’t spread evenly — the thin edges are cooking faster. Next time, push more batter toward the edges to even it out, or trim the scored edge pieces off at the halfway score mark and return the center pieces for more time.
Crackers taste too sour.Your discard was very mature and acidic. Try using fresher discard — within 3-5 days of the last feeding — for a milder flavor. Or lean into it — strong sourdough crackers with sharp cheese is not a bad outcome.
The batter seems too thin.It should be thin. If it’s running off the pan, your parchment isn’t flat or your discard is unusually liquid. Use a pan with a slight rim and spread quickly.
What to Serve With These
These crackers are light enough for:
- Soft cheeses — whipped cream cheese,baked brie, chèvre
- Garlic Scape Hummus or white bean dip
- A smear of butter and a slice of radish
- A drizzle of Hot Honey
- Plain, standing at the counter, between chores
They are not the right cracker for chunky toppings, heavy spreads, or anything that needs structural support. For that, you want a thicker cracker. These are a snacking cracker, and they’re best treated that way.
Variations and Topping Ideas
The base recipe is three ingredients and that’s intentional — but these crackers take well to simple additions. Mix dry ingredients into the batter before spreading, or sprinkle toppings on top just before baking.
Bagel seasoning — the most popular variation. Sprinkle generously over the batter before it goes in. You get sesame, poppy seeds, garlic, and onion in one move. These disappear faster than the plain ones.
Poppy seeds — sprinkle on top before baking. Simple, slightly nutty, good with soft cheese.
Garlic powder — mix a quarter teaspoon into the batter before spreading. Subtle but present. Good with hummus.
Parmesan cheese — stir two tablespoons of finely grated parmesan cheese directly into the batter. It melts in and adds a savory, slightly salty depth. Skip extra salt on top if you go this route.
Coarse salt — if you don’t have Maldon or Diamond Crystal on hand, any coarse salt works. Avoid fine table salt on top — it dissolves into the batter and disappears instead of sitting on the surface where you can taste it.
Red pepper flakes — a pinch on top before baking for a little heat. Good with a charcuterie board alongside soft cheeses and cured meat.

These are the tools that make this recipe easier:
- Half-sheet baking pan — A good heavy pan bakes evenly and won’t warp at temperature.
- Parchment paper sheets — Pre-cut sheets are easier than rolling — no fighting with curling edge.
- Offset spatulas — Makes spreading thin batter much easier than a regular spatula.
- Pasty Wheel — The fastest way to score the crackers at the halfway mark.
- Maldon Sea Salt Flakes — What I use on top. The flat flakes sit on the cracker instead of sinking in.
- Diamond Crystal Kosher Salt — The other option, slightly finer.

Before You Go
These crackers exist because sourdough discard shouldn’t be wasted — and because sometimes the simplest recipe is the best one. Three ingredients, one pan, twenty-five minutes. That’s a good use of something that was headed for the drain.
They disappear so fast – you’ll always make sure you have a lot of extra sourdough discard in the fridge.
Make a batch this week. You’ll probably eat most of them before they cool.

FAQ for Sourdough Discard Crackers
Can I use sourdough discard straight from the fridge?
Yes — this is one of the few recipes where cold discard works exactly as well as room temperature. No need to plan ahead. Pull the jar, measure, mix, and go.
Do I need to feed my starter before making these?
No. These use unfed discard — the stuff you’d otherwise throw away. In fact, discard that’s been sitting a few days develops more acidity, which gives the crackers better flavor. If you’re still getting your starter routine sorted, this guide to feeding and maintaining your sourdough starter will help.
Why do I score them halfway through baking instead of before?
Scoring raw batter just drags and closes back up. Scoring after full baking cracks the crackers rather than cutting them cleanly. Halfway through, the batter has set enough to hold a score line but is still soft enough for a clean cut.
Can I add flavoring — herbs, garlic, cheese?
Yes. Mix dried herbs or garlic powder into the batter before spreading. Finely grated parmesan stirred in works well. Keep additions light — this is a thin batter and heavy additions don’t incorporate evenly.
How thin should I spread the batter?
As thin as you can manage while keeping it even — roughly 1/8 inch. Thinner = crispier. Thicker areas will be chewier and take longer to bake.
What if my discard has been in the fridge for two weeks?
Check it first. If it smells alcoholic and sour but not rotten, it’s still good. Stir in any liquid that has separated and use it. Very old discard will produce a more aggressively sour cracker — which some people prefer.
Can I use a silicone mat instead of parchment?
Parchment is better here. Silicone holds moisture slightly longer, which can interfere with getting a fully crisp cracker. Parchment releases moisture more freely.
How do I store them and how long do they keep?
Store completely cooled crackers in an airtight container at room temperature. Best within 3-4 days. If they soften, a few minutes in a 300°F oven brings the crispness back.
Can I double the batch?
Yes — use two sheet pans and rotate them halfway through baking. Don’t crowd one pan or the batter will be too thick.
