What Are Whole Wheat Sourdough Discard Crackers?
These crackers are made using sourdough discard, the leftover portion of a sourdough starter that’s usually removed before feeding. Instead of wasting it, you can turn it into a crunchy, savory treat. The combination of whole wheat flour, olive oil, and seasonings creates a wholesome and deeply flavorful cracker with a satisfying crunch.

- Zero waste – A great way to use up sourdough discard.
- Simple ingredients – Made with pantry staples you likely already have.
- Crispy and flavorful – Perfectly crunchy with a hint of tangy sourdough taste.
- Customizable – Easily adjust the seasonings to your preference.
Ingredients
- 1 cup (240 g) sourdough discard
- ½ cup (60 g) whole wheat flour
- 2 tbsp olive oil
- ½ tsp salt
- ½ tsp garlic powder (optional)
- ½ tsp dried herbs (like rosemary or thyme)
- Flaky salt for topping

Step-by-Step Instructions
1. Prepare the Dough
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. In a mixing bowl, combine the sourdough discard, whole wheat flour, olive oil, salt, garlic powder, and dried herbs. Stir until the mixture forms a smooth, cohesive dough.
2. Roll Out the Dough
Place the dough between two sheets of parchment paper and roll it out as thinly as possible. The thinner the dough, the crispier the crackers will be. Carefully remove the top sheet of parchment paper.
3. Score and Season
Use a knife or pizza cutter to score the dough into small squares or rectangles. Lightly sprinkle flaky salt over the surface for extra flavor.
4. Bake the Crackers
Transfer the parchment-lined dough onto the baking sheet. Bake for 18–22 minutes, or until the crackers are golden brown and crisp. Keep an eye on them, as baking time may vary based on thickness.
5. Cool and Serve
Allow the crackers to cool completely before breaking them apart along the scored lines. This helps them crisp up even more.

Serving Suggestions
- Enjoy with hummus, cheese, or your favorite dip.
- Pair with soups or salads for extra crunch.
- Serve as part of a charcuterie board.
Storing and Freezing
Storage Tips
Store the crackers in an airtight container at room temperature for up to a week. If they lose their crispness, pop them in a 300°F (150°C) oven for a few minutes to refresh.
Freezing Instructions
While these crackers are best enjoyed fresh, you can freeze the rolled-out dough before baking. Simply wrap it tightly in plastic wrap and freeze for up to 3 months. When ready to bake, let it thaw slightly, then bake as directed.
Recipe Variations
- Cheesy Crackers – Add ¼ cup of grated Parmesan or cheddar to the dough.
- Spicy Version – Sprinkle in a pinch of red pepper flakes for heat.
- Seeded Crackers – Top with sesame seeds, poppy seeds, or sunflower seeds before baking.
- Gluten-Free Option – Substitute whole wheat flour with a gluten-free flour blend.
FAQs
Can I make these crackers without oil?
Yes, but they may be less crispy. You can try substituting oil with melted butter or an equal amount of water for a leaner version.
How do I make sure my crackers are crispy?
Roll the dough as thin as possible and bake until golden brown. If they are still slightly soft after cooling, return them to the oven for a few more minutes.
Can I use all-purpose flour instead of whole wheat flour?
Yes! All-purpose flour will work, but whole wheat flour adds a nuttier flavor and a slightly heartier texture.
