Sourdough Rye Crackers with Coriander and Fennel: A Crunchy Culinary Journey
Bake rustic, tangy crisps at home using starter discard for bold, aromatic bites.

Sourdough Rye Crackers with Coriander and Fennel
Sourdough rye crackers offer a perfect canvas for bold flavors and a satisfying crunch. When combined with the peppery warmth of coriander and the sweet, grassy aroma of fennel, these crackers transcend the ordinary, making an ideal snack or an accompaniment for cheese boards. Recipes that utilize sourdough discard not only help minimize food waste but also naturally infuse the crackers with a subtle tang and robust character.
Introduction: The Art of Sourdough Crackers
Sourdough crackers are a delicious and resourceful way to use up excess sourdough starter, particularly the discard generated when maintaining an active starter. Rye flour’s earthy depth, when paired with aromatic spices like coriander and fennel, creates complexity and aroma beyond standard cracker fare. This combination, both rustic and elegant, draws inspiration from old-world European baking traditions while offering flexibility for modern home kitchens.
Why Use Sourdough Discard?
- Flavor amplification: Sourdough starter provides a mild tang that balances rye’s earthiness and the floral flavors of coriander and fennel.
- Sustainability: Utilizing discard reduces kitchen waste and ensures your starter is consistently refreshed.
- Texture: Sourdough discard yields crackers that are crisp yet tender, with a pleasant snap.
Recipes that leverage discard often call for 100% hydration starter (equal parts flour and water by weight), ensuring ideal moisture balance for cracker dough.
Recipe Overview
This recipe yields thin, crackling rye crackers seasoned generously with crushed coriander and fennel seeds. The dough can be rolled by hand or with a pasta roller, ensuring maximum crispness and even baking.
Ingredients List
- 200g sourdough starter discard (100% hydration)
- 40g rye flour
- 60g whole wheat flour (or all-purpose for lighter texture)
- 32g olive oil (extra virgin recommended)
- 1/2 teaspoon fine sea salt
- 2 teaspoons coriander seeds, lightly crushed
- 2 teaspoons fennel seeds, lightly crushed
- Flake salt (for topping)
Optional variations: Add sesame seeds, poppy seeds, or a dash of black pepper. Substitute rye with barley flour for subtle sweetness or use a mix of flours for different textures.
Step-by-Step Instructions
- Mix the dough: In a large bowl, combine sourdough discard, rye flour, whole wheat flour, olive oil, and salt. Mix until the dough forms a sticky, cohesive ball.
- Season: Sprinkle in the crushed coriander and fennel seeds; knead until well distributed.
- Rest: Wrap dough tightly; chill for at least 30 minutes and up to 24 hours to relax gluten and enhance flavors.
- Shape: Divide dough into quarters. On a floured surface or using a pasta roller, roll each piece into a thin rectangle; aim for uniform thickness (about 1/16 inch).
- Topping: Lay rolled dough pieces onto parchment-lined baking sheets, brush lightly with water, and sprinkle with flake salt (plus more coriander or fennel, if desired).
- Bake: Preheat oven to 350°F (175°C). Bake sheets for 12–15 minutes or until golden brown and crispy, switching racks midway for even cooking.
- Cool: Transfer crackers to a rack to cool. Crack or break into rustic pieces for serving.
Pro Tips for Success
- Roll the dough as thinly as possible for shatteringly crisp crackers.
- Use a pasta roller for uniform thickness and professional appearance.
- Rotate baking sheets during cooking to prevent uneven browning.
- Store cooled crackers in an airtight container to maintain crunch for up to a week.
- Experiment with spice blends and seeds atop crackers for variety.

Frequently Asked Questions (FAQs)
How thin should I roll the dough for crackers?
For maximum crispness, roll the dough to about 1/16 inch (1.5mm) thick. Thinner dough yields crunchier crackers; thicker pieces may bake unevenly and stay soft.
Can I use fresh sourdough starter instead of discard?
Yes, both fresh and mature discard work well, as long as starter is at 100% hydration. Recently fed starter may impart more tanginess; older discard gives subtler sour notes.
How do I store homemade crackers?
Store fully cooled crackers in an airtight container at room temperature. Avoid refrigeration, as this can soften crackers and diminish crispness.
Can I freeze sourdough cracker dough?
Absolutely. After shaping into a ball, wrap tightly and freeze for up to one month. Thaw overnight in the refrigerator before rolling and baking.
Why use rye flour instead of just wheat flour?
Rye flour adds unique nutty, earthy flavors and contributes to the cracker’s rich color and aroma. It also complements the botanical notes of coriander and fennel more robustly than wheat alone.
Troubleshooting & Tips
- If crackers become chewy: Bake longer or return briefly to the oven at a low temperature (250°F) to restore crispness.
- Patchy browning: Rotate pans halfway through and ensure even rolling.
- Dough sticks while rolling: Chill longer or use parchment and dusting flour.
- Need gluten-free? Substitute rye and wheat with 1:1 gluten-free flour and add flaxseed meal for binding, though texture will differ.
Origins and Inspiration
