Sourdough Discard Crackers

Customize this base recipe to make any flavor of sourdough crackers you want!
Prep Time 10 minutes
Cook Time 50 minutes
Total Time 1 hour
Servings 1 batch


  • 1 sheet pan
  • 1 Parchment Paper
  • 1 small mixing bowl and spoon
  • 1 dough cutter/knife to score
  • 1 kitchen scale to weigh ingredients


  • 200 grams unfed sourdough starter (sourdough discard) room temperature is easier to work with but out of the fridge is fine
  • 28 grams butter or olive oil can be substituted
  • 1/4 tsp sea salt plus extra 1/4 tsp to sprinkle on top
  • 1 tbsp seasonings of your choice! cheese, dried spices like rosemary etc.


  • Preheat oven to 325 degrees Fahrenheit. Weigh out 28 grams of butter in small bowl. Melt in microwave for 15-30 seconds until completely liquid. (If you are using olive oil just add 28 grams of olive oil to a small bowl and skip the microwave step)
  • Let butter cool for a few minutes.
  • Add 200 grams of sourdough starter and 1/4 tsp salt to the bowl with the butter already in it.
  • Optional: Add in extras! Add in shredded cheese for cheese crackers (I eyeball about 1-2 tablespoons for cheese). For spices I add 1 tablespoon of ONE of the following: Italian Spice Blend, Rosemary, Garlic. You can experiment with add-ins and seasonings to find a blend you really like!
  • Stir until everything is mixed together really well.
  • Pour the mixture out onto a piece of parchment paper on the sheet pan. Use the back of your spoon to smooth out the mixture until it is thin and even throughout the whole parchment paper.
  • Sprinkle the remaining 1/4 tsp of salt all over the top of the crackers.
  • Bake for ten minutes at 325 degrees.
  • Take crackers out of the oven after the first ten minutes, and lightly score them with your dough cutter or butter knife in squares.
  • Return to the oven and bake another 40 minutes or until golden brown. Your oven may be hotter than mine so keep an eye on them around 30 minutes.
  • After they are done baking allow them to cool completely on the baking sheet before you break them apart (if you can wait that long!) 🙂
  • Store in airtight container at room temperature. They stay fresh about 7-10 days.
