Sourdough Discard Crackers — The Zero-Waste TikTok Snack That Beats Store-Bought

If you’ve ever maintained a sourdough starter, you know the guilt of throwing away discard every feeding. TikTok’s sourdough community solved this with discard crackers — and they’re not just “good for a use-it-up recipe.” They’re genuinely better than most crackers you can buy. Thin, shatteringly crispy, tangy, and endlessly customizable.

Why These Went Viral

The simplicity and the crunch. Spread discard on a sheet pan, season it, bake it, break it into crackers. That’s it. The ASMR crack of snapping the thin crackers and the satisfying shatter when you bite into them made these a TikTok sensation among the sourdough community and beyond.

The Secret to Perfect Discard Crackers

Roll or spread them as thin as possible. The thinner the cracker, the crispier it gets. Use parchment paper on both sides and roll until you can almost see through the dough. Any thick spots will be chewy instead of crispy.

Bake at 350°F and watch carefully — they go from perfect to burnt in about 2 minutes. The edges will crisp first, so rotate the pan halfway through.

Cost Breakdown

A box of artisan crackers at the store costs $5-8. These use starter you’d otherwise throw away plus a drizzle of olive oil and salt. Essentially free crackers that taste like a $12 artisan product.

Pro Tips From the Comments Section

• Parmesan and rosemary is the gourmet combo that people lose their minds over
• They crisp up more as they cool — if they’re slightly bendy out of the oven, they’ll still crunch up
