Ingredients 

  • 230 grams sourdough discard, unfed 1 cup
  • 110 grams all-purpose 1 cup, or whole wheat flour (or a mix)
  • ½ teaspoon sea salt flaky
  • 60 grams unsalted butter 4 tablespoons, room temperature
  • 20 grams Parmesan ¼ cup, finely grated
  • 2 tablespoons nutritional yeast
  • Oil for brushing
  • Coarse salt for topping

Instructions

  • In a bowl, mix the sourdough discard, flour, salt, butter, Parmesan, and nutritional yeast until you get a smooth dough. It should not be sticky, add a little flour if needed.
    Shape the dough into a rectangle, wrap it in plastic, and chill for 30 minutes (or up to 2 hours).
  • Preheat the oven to 350°F (175°C). Roll the dough on parchment paper to about 1/16 inch thick. Try to keep it even, but rustic edges are fine.
  • Use a fork to prick the dough all over to stop it from puffing up. Cut the dough into squares or rectangles with a knife or pizza cutter.
  • Transfer the parchment with the dough to a baking sheet. Bake for 20–25 minutes, turning the pan halfway through. The crackers should be golden and crisp around the edges.
  • Let them cool completely on a wire rack. Store in an airtight container for up to 1 week, or freeze for longer.

Notes

  • Chilling the dough helps the crackers hold their shape and makes rolling easier. Don’t skip this step—it’s worth the short wait!
  • Roll evenly so the crackers bake uniformly. Thicker spots may stay soft while thinner ones brown too quickly.
  • Pricking the dough with a fork keeps the crackers from puffing up.
