How to Make Crispy Sourdough Cheddar Crackers: Tangy, Savory & Zero-Waste Snack Recipe
Step 1: Preheat and Prepare
Start by getting your oven warmed up to 350°F (175°C) and lining a baking sheet with parchment paper. This simple step ensures your crackers bake evenly and don’t stick, making cleanup a breeze and getting you one step closer to snacking bliss.
Step 2: Combine The Wet Ingredients
In a mixing bowl, blend together your room-temperature sourdough discard, melted butter, and shredded sharp cheddar cheese until they’re fully incorporated. This mixture is where all the tangy, savory magic begins, setting the foundation for flavorful crackers.
Step 3: Add Dry Ingredients and Form Dough
Next, sprinkle in the flour, salt, garlic powder, onion powder, and any optional spices. Stir everything together until a cohesive dough forms. This step is crucial because the flour and spices help balance the moisture and amplify the flavor, giving your crackers body and bite.
Step 4: Roll Out the Dough
Place your dough between two sheets of parchment paper and roll it out super thin—about ⅛ inch thick or less. Getting the dough thin is key to achieving the ultimate crisp texture that will snap delightfully with each bite.
Step 5: Cut Into Shapes
Use a knife or pizza cutter to slice the rolled-out dough into squares or any fun shapes you like. This is your chance to get creative! Uniform pieces help ensure even baking, making every cracker perfectly golden and crisp.
Step 6: Prep for Baking
Transfer your cut crackers to the lined baking sheet and gently prick each one with a fork. These tiny holes allow steam to escape and prevent puffing, giving you flat, crispy crackers that are just right.
Step 7: Bake to Perfection
Bake for 20 to 25 minutes until the edges turn golden brown and the entire batch smells irresistibly savory. Don’t forget to rotate the pan halfway through baking for an even crunch all across the tray.
Step 8: Cool Completely
Let your Crispy Sourdough Cheddar Crackers cool fully on a wire rack. This last step lets them crisp up all the way and ensures they stay perfectly crunchy when you store them.
How to Serve Crispy Sourdough Cheddar Crackers: Tangy, Savory & Zero-Waste Snack Recipe

Garnishes
Garnishing these crackers can elevate your snack experience to delicious new heights. Try a sprinkle of flaky sea salt or a light brush of olive oil and a dusting of smoked paprika before serving. A tiny dollop of your favorite mustard or a swipe of cream cheese can also make your bite pop with extra zest and creaminess.
Side Dishes
Pair your crackers with fresh veggies, like crisp cucumber slices or sweet cherry tomatoes for a refreshing contrast. They’re also fantastic alongside hearty charcuterie boards, perfect with slices of salami, olives, and some tangy pickles. And don’t forget the classic combo: a bowl of homemade tomato soup or creamy brie cheese beside these crackers is pure comfort food gold.
Creative Ways to Present
Looking to impress at your next gathering? Arrange these delightful crackers in a layered glass jar for a rustic display, or stack them artistically on a slate board with sprigs of rosemary and little ramekins of honey or fig jam. You can also thread smaller cracker bites on toothpicks to create charming appetizer “skewers.” The Crispy Sourdough Cheddar Crackers: Tangy, Savory & Zero-Waste Snack Recipe is versatile, perfect for both casual snacking and fancy occasions alike.
Make Ahead and Storage
Storing Leftovers
Once fully cooled, keep your crackers crisp and fresh by storing them in an airtight container at room temperature. Properly sealed, they can retain their crunchiness for up to one week, making them the perfect make-ahead snack for busy days.
Freezing
If you want to enjoy these crackers longer, they freeze beautifully. Simply place cooled crackers in a freezer-safe bag or container and freeze for up to three months. When you’re ready to indulge, just thaw at room temperature and enjoy their fresh-baked flavor.
Reheating
To bring back their original crispiness after storage or freezing, pop the crackers in a preheated oven at 300°F (150°C) for 5 to 7 minutes. This gentle reheating refreshes their texture without burning or drying them out, so every bite stays as tantalizing as the first.
FAQs
Can I use sourdough starter that has been fed instead of discard?
While this recipe specifically calls for unfed sourdough discard, using fed starter is possible but may affect the dough’s consistency and flavor. The discard’s thicker texture and tangier taste are what make these crackers uniquely delicious and crisp.
What if I’m allergic to dairy? Can I substitute the cheddar cheese?
Absolutely! You can try using a dairy-free cheese alternative that melts well, such as vegan cheddar shreds. Keep in mind, the flavor profile may be milder, but you can boost it by adding more savory spices.
How thin should I roll the dough for the crispiest crackers?
For the best crispiness, roll your dough very thin—about an eighth of an inch or even thinner if you can manage it. The thinner the dough, the crispier your crackers will be after baking.
Can I add other flavors to customize these crackers?
Definitely! This recipe is a fantastic base for experimentation. Try adding fresh herbs like thyme or chives, or spices like cumin or smoked paprika to suit your taste and create unique flavor twists.
How do I prevent my crackers from becoming soggy when stored?
Ensure your crackers are completely cooled before storing, and use an airtight container in a dry place. Avoid storing near items that release moisture, as this can cause sogginess.
