Crispy Vegan Sourdough Discard Crackers with Za'atar
If you’ve got a jar of sourdough discard hanging around in the fridge, these crispy vegan crackers with olive oil and za’atar are about the easiest way to turn it into something genuinely delicious. A handful of pantry staples, a hot oven, and you’re done. They bake up shatteringly crisp, with that warm, herby, slightly tangy flavor you get from good za’atar and decent olive oil. No eggs, no dairy, no fuss. Just a snack that beats anything you’d grab off a store shelf.
Why This Recipe Works
Sourdough discard isn’t just something to pour down the drain. It’s a flavor-packed ingredient hiding in plain sight. Baked thin and dry, the mild sourness in discard plays off za’atar’s earthy thyme, sumac, and toasted sesame beautifully. Olive oil brings richness and helps the crackers crisp evenly in the oven, and a light brush of oil plus extra seasoning right before baking gives them that bakery-counter finish.
This recipe happens to be naturally vegan, needs zero special equipment, and works with discard that hasn’t been fed. In other words, it’s exactly the stuff you’d normally scrape out and toss during routine starter maintenance.
Ingredients
- 1 cup (about 227g) unfed sourdough discard
- 2 tablespoons extra virgin olive oil, plus more for brushing
- 1 tablespoon za’atar seasoning, plus extra for topping
- 1/2 teaspoon fine sea salt, plus flaky salt for finishing
- 1/4 teaspoon garlic powder (optional, for depth)
- 2–4 tablespoons all-purpose or whole wheat flour, if needed to thicken
Ingredient Notes
- Discard consistency matters. If your discard is thick, like pancake batter, you probably won’t need any extra flour. If it’s thin and watery, add flour a tablespoon at a time until it’s spreadable but not runny.
- Za’atar varies wildly by brand. Some blends lean salty, others don’t. Taste yours before adding more salt than the recipe calls for.
- Olive oil quality actually shows here. This recipe has so few ingredients that a mediocre oil will flatten the whole thing. Use something you’d happily drizzle on bread. It’s the main flavor carrier besides the za’atar itself.
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 375°F (190°C). Line a large baking sheet with parchment paper.
2. Mix the Dough
In a medium bowl, combine the sourdough discard, olive oil, za’atar, salt, and garlic powder. Stir until smooth. If the mixture seems too loose to spread thinly, mix in flour a tablespoon at a time.
3. Spread It Thin
Pour the batter onto the parchment-lined sheet. Using an offset spatula or the back of a spoon, spread it as thin and evenly as you can manage, about 1/16 inch. Thin spreading is really the whole secret here. Thick spots stay chewy no matter how long you bake them.
4. Season the Top
Brush the surface lightly with olive oil, then sprinkle generously with extra za’atar and a pinch of flaky salt.
5. Score Before Baking
Using a pizza cutter or sharp knife, score the dough into cracker-sized squares or rectangles. Skip this step and you’ll end up snapping a giant sheet of crackers into random shards later, which is fine too, honestly, but scoring makes things neater.
6. Bake
Bake for 18–22 minutes, rotating the pan halfway through. Keep an eye on things in the last 5 minutes, since the edges brown faster than the center. You’ll know they’re done when they look golden and feel firm, not soft, to the touch.
7. Cool and Crisp
Turn off the oven, crack the door open, and let the crackers sit inside for about 10 minutes. This gives any leftover moisture a chance to evaporate, which is what gets you maximum crunch. Once fully cooled, break along the scored lines.
Tips for Extra Crispy Crackers
- Spread thin, not thick. Uneven thickness is cause number one of soggy centers. Thicker spots just won’t dry out in time.
- Don’t skip the resting step. Letting the crackers cool inside the (turned-off) oven locks in that crispiness you worked for.
- Score midway if your batter sets fast. Cutting lines around the 12-minute mark can work just as well as scoring before baking, if your batter firms up quickly.
- Store them properly. Keep cooled crackers in an airtight container at room temperature, and they’ll hold for about a week. If they go soft, re-crisp in a 300°F oven for 5 minutes.
Flavor Variations
- Spicy za’atar: Stir in 1/4 teaspoon chili flakes or Aleppo pepper.
- Everything-style: Swap half the za’atar for an everything bagel seasoning blend.
- Herbed olive oil crackers: Drop the za’atar entirely and use chopped fresh rosemary plus cracked black pepper instead.
- Seedy crunch: Mix in 1 tablespoon sesame or flax seeds for texture.
Frequently Asked Questions
Can I use fed sourdough starter instead of discard? You can, but discard is really the better fit here since it doesn’t need to be active to work. Fed starter is fine in a pinch, though honestly it’s more useful saved for actual bread.
Are these crackers gluten-free? Not as written, no, since they depend on flour-based discard. Want a gluten-free version? Use a gluten-free sourdough discard made from rice flour or a gluten-free all-purpose blend instead.
What goes well with za’atar crackers? Hummus, baba ganoush, labneh (or a vegan yogurt dip), or just a drizzle of olive oil with some sliced tomatoes. Any of these turns a simple cracker into a proper mezze spread.

These crispy vegan sourdough discard crackers with olive oil and za’atar prove that discard doesn’t need to end up in the trash.
