Sourdough Discard Crackers: Best Thin, Crispy, Tangy Snack

A tray of thin sourdough discard crackers broken into rustic pieces, served with hummus and a small bowl of olives on a kitchen counter.

These Sourdough Discard Crackers are thin, crispy, and full of that tangy sourdough flavor you can’t fake. They’re the ultimate no-waste sourdough discard recipe because you turn “leftovers” into a crunchy snack that feels kind of fancy. The best part? You only need a few simple ingredients, and the oven does most of the work.

If you have sourdough discard in your fridge, this is the snack you’ll make on repeat. The batter is spread thin like a sheet, baked, and then snapped into pieces. It’s perfect for charcuterie boards, soups, dips, or just standing at the counter grabbing “one more.”

Trust me—don’t skip spreading it thin. That’s the difference between crispy crackers and chewy ones.

Ingredients for Sourdough Discard Crackers

Sourdough discard (3/4 cup): The base flavor and structure. Use cold discard or room temp—both work.
Melted butter (2 tablespoons): Adds richness and helps the crackers crisp. Substitute: olive oil (use a good one so it tastes clean).
Fine sea salt (1/4 teaspoon): Seasons the batter.
Dried herbs (2 teaspoons): Adds flavor fast. Try Italian seasoning, rosemary, thyme, or herbs de Provence.
Salt for sprinkling (1/4 teaspoon): Helps season the top evenly. Optional: swap for everything seasoning.

Sourdough Discard Crackers Recipe Step-by-Step

1. Preheat your oven to 325°F and line a baking sheet with parchment paper. (Parchment makes it easy to spread and remove.)
2. Melt the butter and let it cool for a minute so it doesn’t cook the discard.
3. Stir the sourdough discard, dried herbs, and salt into the melted butter until smooth and fully combined. The batter will be thin and spreadable.
4. Spread the mixture into a very thin, even layer on the parchment. Use an offset spatula if you have one. If it looks too thick, keep spreading—thin = crispy.
5. Sprinkle the top evenly with your extra salt (or seasoning blend).
6. Bake for 10 minutes, then pull the pan out and score the sheet into squares using a knife or pizza cutter (this helps you get neat crackers).
7. Return to the oven and bake 20–50 minutes more, until golden and dry. Check around the 20–30 minute mark the first time you make them—oven temps vary.
8. Cool completely, then break apart along the score lines (or into rustic pieces). Store airtight.

Tips for Perfect Sourdough Discard Crackers

Spread thinner than you think: Thick spots stay bendy.
Watch the edges: If edges brown early, pull off the done pieces and let the center keep baking.
Score after 10 minutes: The sheet “sets” so you can cut clean lines.
Cool fully for crunch: They crisp up as they cool—don’t judge them hot.
Season smart: Mix herbs into the batter, then sprinkle a little on top for big flavor.

Variations & Substitutions

Everything seasoning crackers: Stir 1–2 teaspoons into the batter and sprinkle more on top.
Cheesy version: Add 1/3 cup finely grated parmesan to the batter.
Spicy: Add a pinch of cayenne or red pepper flakes.
Sesame or poppy seed: Sprinkle seeds on top right before baking.
Dairy-free: Use olive oil or melted plant-based butter.
“Lazy” rustic: Skip scoring and just break into pieces once cool.

Storing & Reheating

Room temperature: Store in an airtight container for up to 7 days.
To re-crisp: Warm in a 300°F oven for 5–8 minutes if they soften.
Freezer: Not necessary, but you can freeze for up to 2 months and re-crisp in the oven.

Serving Suggestions & Pairings

With hummus, spinach dip, or guacamole.
On a charcuterie board with cheese, fruit, and nuts.
Alongside soup as a crunchy topper.
Crushed over salads for “crouton” vibes.
