These sourdough crackers are light and buttery, yet crispy! They’re “nutty-tasting” from the seeds and have a rich flavour from the sourdough.


  • ¾ cup all purpose flour
  • ¼ cup ground flax
  • ¼ cup chia seeds
  • ¼ cup butter, softened to room temperature
  • ½ tsp salt
  • 1 cup active (fed)  sourdough starter


  1. Combine all ingredients into a dough. You may need to use your hands to finish gathering it all together.
  2. Wrap dough in plastic wrap or in a ziplock bag. Place in fridge for at least 30 minutes to firm up. 
  3. Preheat oven to 350 degrees Fahrenheit.
  4. Roll dough out to 1/16  inch thick. If you have a pasta maker, this machine works really well to roll the dough out to a uniform thickness!
  5. Cover two baking sheets with parchment. Place the rolled out dough onto the parchment. Slice into 1 inch squares. A pizza roller works well!
  6. Poke each square with a fork. 
  7. Bake for 10 minutes. Rotate each pan and swap the bottom pan for the top pan. 
  8. Bake another 10-15 minutes, or until the tops start to turn golden.
