Expert Baking Tips

  1. Roll as thin as possible: Aim for about 1/16-inch for crispy crackers. Thicker dough yields a more “bready” result.
  2. Relax the dough if it springs back: Let it rest a few minutes and then roll again.
  3. Press toppings in: Rolling over toppings once helps them adhere and stay put during baking.
  4. Watch the oven: Thin crackers brown quickly; check in the final minutes.
  5. Cool fully before storing: Crunch develops as they cool.

How to Cut Sourdough Discard Crackers

The key to crisp crackers is rolling the dough thin. Once rolled, cut however you like:

  • Use a pizza cutter or ravioli cutter to score a grid for uniform crackers.
  • Use cookie cutters or biscuit cutters for fun shapes, and bake the scraps too—they’re tasty.
  • Bake as a whole sheet and break pieces apart after baking for a rustic presentation.

Storage

Room temperature: Store fully cooled crackers in an airtight container at room temperature for up to 5 days to maintain crispness. Do not refrigerate.

Recipe FAQs

What is sourdough discard?

Sourdough discard is the portion of starter removed when you feed your starter. Instead of throwing it away, you can use it in recipes like these crackers to add flavor and reduce waste.

Why is my dough “bouncing back”?

If the dough springs back while rolling, let it rest a few minutes. The gluten needs time to relax before you continue rolling.

What toppings can I use?

Classic sea salt works well. Other options include sesame seeds, poppy seeds, everything bagel seasoning, fresh herbs, cracked black pepper, and grated parmesan.

Equipment

  • Kitchen scale
  • Parchment paper
  • Half-sheet baking pans
  • Pizza cutter or sharp knife

Ingredients

  • 1 cup all-purpose flour
  • 200 grams (about ¾ cup) sourdough discardunfed, at room temperature
  • 2 Tablespoons olive oil
  • 1 teaspoon kosher salt
  • 1 Tablespoon water
  • Toppings optional

Instructions

  • In a stand mixer bowl or a large mixing bowl, combine the flour, sourdough discard, olive oil, and salt. With the mixer on low, add the water. Increase to medium and mix until a smooth dough forms. You can also knead by hand. The dough should be smooth and not sticky; add a pinch more flour if needed.
  • Divide the dough into two pieces and place each on a piece of parchment paper. Flatten each into a disk with your hands and let rest 5 minutes.
  • Preheat the oven to 450°F (230°C).
  • Roll each disk to about 1/16-inch thickness, nearly covering the parchment. Sprinkle with toppings and roll once more to press them in.
  • Use a pizza cutter or sharp knife to cut the crackers to your desired size. Prick each cracker with a fork to prevent puffing. Transfer the parchment with the dough onto a baking sheet.
  • Bake 10–12 minutes, watching closely near the end, until the edges just begin to brown. Remove from the baking sheet and let cool completely before serving.

Notes

You can use cookie cutters to make shaped crackers. Be sure to bake the dough scraps—those pieces are delicious too.

To use active sourdough starter: Substitute the discard with 200g active starter; no other ingredient changes are necessary.
