Easy Sourdough Discard Crackers

This recipe can liven up your sourdough discard into super fast and easy crackers. With a little bit of flax seeds, flaky salt, and endless variations, these crackers are my go-to easy sourdough discard recipe. They go great with some cheese!

  • Baking sheet
  • Rolling Pin
  • Cookie cutter


  • 30g olive oil
  • 50g sourdough starter
  • 10g flaxseeds
  • ¼ teaspoon salt
  • 60g flour
  • flaky salt, for topping


  • Preheat the oven to 350F.
  • In a bowl, stir together the olive oil, starter, flaxseeds, and salt with a spoon or spatula (it may not fully combine, this is okay). Add the flour and stir until the dough comes together. On a clean work surface, knead the dough until it is evenly colored and textured (probably will take only 30 seconds to a minute!). Place the dough back in the bowl and cover, then let rest for 10 minutes.
  • Line a baking sheet with parchment paper. After the resting period, roll out the dough on your work surface, lifting and rotating the dough after the first few rolls. Roll until quite thin like a cracker should be, but you don’t have to be super particular.
  • Use a cookie cutter to cut out your crackers as desired and place them on the baking sheet (they can be close together but not touching). Knead & re-roll any scraps.
  • When your baking sheet is filled, use a fork to prick the center of each cracker once. Sprinkle some flaky salt over the crackers.
  • Bake for 14 minutes. Cool slightly and consume! Let me know what you think below in the comments or on Instagram @higheralchemybaking!
