Sourdough Crackers are a simple and crispy snack made with just three ingredients: sourdough starter, flour, and oil. Their crunchy texture and lightly tangy flavor make them perfect for munching on their own or pairing with cheese and dips. They’re an easy recipe that comes together quickly, especially if you’re already saving some sourdough starter from your bread baking adventures.
I love making these crackers because they’re so straightforward and don’t require any fancy ingredients or long prep times. Plus, using leftover sourdough starter means nothing goes to waste, which feels good! Rolling the dough thin and sprinkling a bit of sea salt on top is my favorite step — it really amps up the flavor and crunch.
My favorite way to enjoy sourdough crackers is fresh out of the oven, still warm and crispy. They’re great for snacking anytime or serving at gatherings alongside your favorite spreads. I’ve found that once you try making these, store-bought crackers just don’t compare anymore!
Key Ingredients & Substitutions
Sourdough starter: This is the star ingredient and adds tangy flavor plus a bit of natural leavening. You can use discard (unfed) or active starter. If you don’t have sourdough starter, yogurt or buttermilk can be an alternative but expect a different flavor.
Flour: All-purpose flour works best for a crisp texture. You can try whole wheat or spelt for a nuttier flavor, but the crackers may be less crisp. Gluten-free blends might work, but use a mix that includes xanthan gum for binding.
Olive oil: Olive oil adds flavor and helps the dough hold together. You can swap in any neutral oil like vegetable or avocado oil if you prefer a milder taste.
How Do You Roll Out the Dough Thin Enough for Crispy Crackers?
Rolling the dough very thin is key to getting crackers that are crunchy and bake evenly. Here’s what helps:
- Lightly flour your surface and rolling pin to prevent sticking, but don’t overdo it or your dough gets tough.
- Roll the dough to about 1/8 inch (3mm) thick—that’s thin enough to crisp up without burning quickly.
- If the dough resists rolling, let it rest a few minutes to relax the gluten and become easier to work with.
- Score the dough before baking so you can break the crackers cleanly after they cool.
Patience here makes a big difference. Thin, even dough means tasty, crispy crackers every time!

Equipment You’ll Need
- Baking sheet – a flat surface that ensures even baking and crisp crackers.
- Parchment paper – prevents sticking and makes cleanup easy.
- Rolling pin – helps you roll the dough thin and even for perfect crunch.
- Knife or pizza cutter – to score the dough for easy breaking into crackers.
- Mixing bowl – for combining your simple ingredients quickly and easily.
Flavor Variations & Add-Ins
- Add dried rosemary or thyme for an herbal touch that pairs well with cheese.
- Sprinkle black sesame or poppy seeds for extra crunch and a nutty flavor.
- Mix in garlic powder or smoked paprika for a flavorful kick.
- Try grated Parmesan cheese in the dough for a cheesy, salty twist.
Sourdough Crackers Recipe (3 Ingredients!)
Ingredients You’ll Need:
For the Dough:
- 1 cup (240g) active sourdough starter (discard or fed)
- 1 cup (120g) all-purpose flour (plus extra for dusting)
- 2 tablespoons olive oil (or any neutral oil)
For Topping (Optional):
- Flaky sea salt
- Dried herbs (such as rosemary, thyme, or black sesame seeds)
How Much Time Will You Need?
This recipe takes about 10 minutes of preparation time, then 20–25 minutes to bake. After baking, allow a few minutes for the crackers to cool and crisp up before enjoying.
Step-by-Step Instructions:
1. Prepare Your Oven and Baking Sheet:
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and make cleanup easy.
2. Make the Dough:
In a mixing bowl, combine the sourdough starter, flour, and olive oil. Mix until a dough forms that is firm enough to roll out but not too dry. If it’s sticky, sprinkle in a little more flour until it reaches the right consistency.
3. Roll Out and Shape:
Lightly flour a clean surface and roll the dough out very thin—about 1/8 inch (3mm) thick—for the crispiest crackers. Transfer the rolled dough to the lined baking sheet. Score the dough into squares or rectangles with a knife or pizza cutter to make breaking into crackers easier after baking.
4. Add Toppings and Bake:
Brush the dough lightly with olive oil or water, then sprinkle with flaky sea salt and your favorite dried herbs or seeds if using. Bake for 20 to 25 minutes or until the crackers are golden brown and crisp. Watch closely near the end to avoid burning.
5. Cool and Store:
Remove the crackers from the oven and let them cool completely on the baking sheet; they will continue to crisp as they cool. Once cool, break along the scored lines. Store your crackers in an airtight container for up to a week.
Enjoy these delicious, crunchy sourdough crackers as a snack on their own or paired with cheese and dips!
Can I Use Unfed Sourdough Discard for This Recipe?
Yes! Unfed sourdough discard works perfectly and helps reduce waste. Just make sure it’s not overly runny—if it is, add a bit more flour to get the dough to the right consistency.
How Should I Store Leftover Crackers?
Store the cooled crackers in an airtight container at room temperature. They’ll stay fresh and crispy for up to a week. If they soften, you can re-crisp them in a warm oven for a few minutes.
Can I Add Flavors or Seeds to the Dough?
Absolutely! Feel free to mix in dried herbs, spices, garlic powder, or seeds like sesame or poppy for extra flavor and texture.
What’s the Best Thickness for Rolling Out the Dough?
Roll the dough to about 1/8 inch (3mm) thick. Thinner dough yields crispier crackers, but be careful not to roll too thin or they may burn while baking.
