1 cup sourdough discard (unfed)
½ cup all-purpose flour
2 tablespoons olive oil
½ teaspoon salt
½ teaspoon garlic powder or dried herbs (optional)
Toppings: flaky salt, sesame seeds, everything bagel seasoning, or shredded cheese
Preheat oven to 325°F (160°C). Line a baking sheet with parchment paper.
In a bowl, mix sourdough discard, flour, olive oil, salt, and any optional flavorings until smooth.
Spread or roll the mixture very thinly (about 1/16 inch) on the parchment-lined baking sheet. Use a spatula or offset knife for even spreading.
Score into cracker shapes with a knife or pizza cutter if you want easy break-apart squares.
Sprinkle with flaky salt or toppings of choice.
Bake for 20–25 minutes or until golden and crisp throughout (watch the edges for doneness).
Let cool completely before breaking apart. Store in an airtight container for up to a week.
