Description

Crispy, tangy sourdough discard crackers made from leftover starter. Quick to prepare, endlessly customizable, and perfect for snacking or serving with dips.


Ingredients

Scale
  • 1 cup sourdough discard (unfed, cold or room temp)

  • 1 cup all-purpose flour (or whole wheat/rye)

  • 4 tbsp unsalted butter (or olive oil)

  • ½ tsp sea salt

  • Optional:

    • 2 tbsp fresh herbs or 1 tsp dried

    • 2 tbsp seeds (sesame, poppy, fennel)

    • 2 tbsp grated parmesan or nutritional yeast

    • ½ tsp spices (paprika, garlic powder, za’atar)


Instructions

  • Mix sourdough discard, flour, butter/oil, salt, and optional herbs into a dough.

  • Chill the dough for at least 30 minutes.

  • Roll dough on parchment to 1/16-inch thickness.

  • Add toppings, then lightly roll again to press them in.

  • Cut into squares and dock with a fork.

  • Bake at 350°F (175°C) for 15–20 minutes until golden.

 

  • Cool completely and store in an airtight container.

Notes

  • The thinner the dough, the crispier the crackers.

  • Use parchment paper for easier rolling and baking.

  • Rotate baking sheets halfway for even browning.

 

  • Store at room temperature for up to 2 weeks or freeze for longer shelf life.
