How to Make Sourdough Discard Crackers

1. Preheat the Oven

Preheat your oven to 325°F (165°C) and line a baking sheet with parchment paper.

2. Mix the Batter

In a mixing bowl, combine the sourdough discard, olive oil, salt, garlic powder, and rosemary. Stir until smooth and well combined.

3. Spread the Batter

Pour the mixture onto the lined baking sheet. Use an offset spatula or spoon to spread it into a thin, even layer (about 1/8 inch thick).

4. Add Toppings

Sprinkle Parmesan cheese, everything bagel seasoning, sesame seeds, or flaky salt evenly over the surface.

5. Bake & Score

Bake for 10 minutes. Remove from the oven and use a pizza cutter or sharp knife to lightly score the dough into squares or rectangles.

6. Bake Until Golden & Crisp

Return the baking sheet to the oven and bake for another 20–25 minutes, or until the crackers turn golden brown and crispy.

7. Cool & Break Apart

Let the crackers cool completely on the baking sheet before breaking them into individual pieces along the scored lines.

What to Serve with Sourdough Discard Crackers

  • Cheese & Charcuterie: Pair with Brie, aged cheddar, or prosciutto.

  • Dips: Serve with hummus, guacamole, or a creamy spinach dip.

  • Soups & Salads: A great crunchy addition to tomato soup or a fresh green salad.

Tips for Perfect Crackers

  • Thin & Even Layer: Spread the batter as evenly as possible to ensure every cracker crisps up the same.

  • Score the Dough: Cutting the crackers partway through baking makes them easier to break apart neatly.

  • Cool Completely: Let the crackers cool fully before storing to keep them crunchy.

  • Re-Crisping Tip: If they soften after storage, pop them back in a 300°F (150°C) oven for 5–10 minutes.

How to Store & Keep Crispy

  • Room Temperature: Store in an airtight container for up to a week.

  • Freezing Option: Freeze for up to 3 months and reheat in the oven to restore crispiness.

  • Re-Crisping Tip: If crackers soften, bake at 300°F (150°C) for 5–10 minutes to bring back the crunch.
