- Cooling rack
Materials
- 1 cup about 240 g sourdough discard (unfed starter)
- 1 cup 125 g all-purpose flour (plus extra for dusting)
- 2 tablespoons 30 g unsalted butter, softened (or use olive oil for a vegan option)
- ¼ teaspoon baking soda
- ½ teaspoon salt plus extra for sprinkling on top
- 1 tablespoon dried herbs or seasoning optional; e.g., rosemary, oregano, or Italian blend
- 2 tablespoons water optional, only if needed to bring dough together
- Tip: Adjust seasoning to taste. Experiment with garlic powder onion powder, sesame seeds, or chili flakes for extra flavor.
Instructions
- Combine the Wet Ingredients
- In a mixing bowl, stir together the sourdough discard and softened butter (or olive oil). Mix until well combined.
- Add Dry Ingredients
- Add the all-purpose flour, baking soda, and salt. If you’re using dried herbs or other seasonings, add them now. Mix until a dough starts to form.
- If the dough feels too dry, sprinkle in 1–2 tablespoons of water. If it feels too wet, add a little extra flour.
- Form the Dough
- Transfer the dough onto a lightly floured surface. Knead gently for 1–2 minutes until it’s smooth and not sticky. Avoid overworking the dough; you just want it to hold together.
- Roll Out the Dough
- Preheat your oven to 350°F (175°C).
- Place dough between two sheets of parchment paper or on a floured surface. Use a rolling pin to roll the dough to about 1/8-inch thickness (3 mm). The thinner, the crispier the crackers.
- Cut into Shapes
- Use a sharp knife or pizza cutter to slice the rolled dough into squares or rectangles. Alternatively, use cookie cutters for fun shapes.
- Carefully transfer the cut dough onto a baking sheet lined with parchment paper.
- Optionally, sprinkle a bit of salt or additional herbs on top for extra flavor.
- Bake
- Bake in the preheated oven for 15–20 minutes, or until the edges turn light golden brown. Keep an eye on them as they can over-brown quickly.
- Rotate the baking sheet halfway through to ensure even baking.
- Cool and Store
- Transfer crackers onto a cooling rack to let them cool completely. This helps them crisp up further.
- Store in an airtight container for up to 1 week. If they lose their crunch over time, pop them back in the oven for a few minutes to re-crisp.
