These zero-waste crackers turned my leftover sourdough starter into gold! The tangy sourdough flavor creates incredibly crispy crackers with complex fermented notes that pair perfectly with any cheese or dip.
Preheat your oven to 325°F (163°C) and line a large baking sheet with parchment paper for easy cleanup and even baking.
In a bowl, mix sourdough starter discard, flour, olive oil, and sea salt until smooth—viral tip: the batter should be pourable but not watery for ultra-thin, crispy crackers.
Pour the batter onto the prepared pan and spread it as thin as possible using an offset spatula; viral hack: go for see-through thinness at the edges for beautiful lacy texture.
Sprinkle everything bagel seasoning evenly over the top—this is the viral flavor twist that pops on camera and delivers extra crunch.
Bake for 22–28 minutes until golden and deeply crisp at the edges. Let cool, then break into rustic pieces and serve to wow your feed!
