How to Make Crispy Sourdough Cheddar Crackers (Savory, Tangy & Zero-Waste) Recipe
Step 1: Prep Your Oven and Baking Sheets
Start by preheating your oven to 350°F (175°C) and line two baking sheets with parchment paper. This ensures even baking and easy removal of your crackers later on. The anticipation begins here as your kitchen starts filling with warmth, readying for some savory magic.
Step 2: Mix the Dough
Gather a mixing bowl and combine the flour, butter, shredded cheddar, sourdough discard, and the optional spices—onion powder and smoked paprika. Work the mixture until a thick dough forms. This step is all about bringing diverse textures together — silky butter meeting the crumbly flour and melty cheese — creating a dough that promises crisp bite after baking.
Step 3: Roll Out Your Dough
Divide the dough into two equal parts. Using parchment paper on both sides to prevent sticking, roll each half to about 1/8-inch thickness. This thin layer is key for those satisfyingly crunchy crackers, so take your time to get an even, smooth surface.
Step 4: Score Into Crackers
Carefully remove the top parchment layer and score the dough into small squares with a knife or pizza cutter. You’re creating perfect portions here so that when baked and cooled, they’re easy to break apart and elegantly snackable.
Step 5: Add the Salt
Sprinkle kosher salt evenly over the scored dough. This simple step really elevates the overall flavor profile by highlighting the savory notes and adding a little extra crunch.
Step 6: Bake Until Golden and Crisp
Transfer the prepared dough on parchment to your baking sheets and slide them into the oven. Bake for 12 to 15 minutes, or until you notice the edges turning golden brown and the aroma filling your kitchen. This part is pure delight — watching the transformation from dough to beautifully crisp crackers.
Step 7: Cool and Break Apart
Once baked, let your crackers cool completely on the baking sheets. Cooling is crucial to achieve their signature snap and bite. When fully cooled, gently break them apart along the scored lines, and you have yourself an irresistibly crunchy treat.
How to Serve Crispy Sourdough Cheddar Crackers (Savory, Tangy & Zero-Waste) Recipe

Garnishes
A sprinkle of fresh herbs like thyme or rosemary can add a burst of fragrant freshness to your platter. If you’re feeling adventurous, a dollop of fig jam or a smear of honey pairs exquisitely with the tangy cheddar crackers, balancing savory with sweet notes.
Side Dishes
These crackers shine alongside creamy dips such as hummus, spinach-artichoke dip, or a sharp blue cheese spread. They also make a wonderful companion to charcuterie boards, pairing beautifully with cured meats and pickled vegetables.
Creative Ways to Present
Why not turn these crackers into mini canapés topped with smoked salmon, crème fraîche, and a sprig of dill? Or use them as the crunchy base for bite-sized cheese melts. Their sturdy yet delicate nature means you can get creative with toppings and presentations that impress your guests effortlessly.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Crispy Sourdough Cheddar Crackers (Savory, Tangy & Zero-Waste) Recipe in an airtight container at room temperature. They maintain crispness well for up to a week, perfect for snacking or bringing a little homemade flair to any moment.
Freezing
Although these crackers are best fresh, you can freeze them in a sealed bag or container for up to a month. Just make sure they are completely cooled before freezing to avoid any residual moisture that might soften them.
Reheating
If your crackers lose some crunch, simply pop them in a preheated oven at 300°F (150°C) for 3-5 minutes. This quick refresh brings back that signature crisp texture without drying them out.
FAQs
Can I use fed sourdough starter instead of discard?
It’s best to use sourdough discard for this recipe to keep the dough’s consistency balanced. Fed starters have more active yeast, which might alter the texture and flavor of your crackers.
Can I substitute the cheddar cheese?
Absolutely! While sharp cheddar is classic here, feel free to experiment with other cheese varieties like Gruyère or Parmesan for unique flavor profiles.
Is it necessary to roll the dough thin?
Yes, rolling the dough to about 1/8-inch thickness is essential to achieve that perfect crisp bite and golden color typical of these crackers.
How do the optional spices affect the flavor?
Onion powder adds umami depth, while smoked paprika introduces a gentle smoky warmth. Both are optional but can enhance the overall flavor complexity deliciously.
What if I don’t have parchment paper?
You can lightly grease your baking sheets instead, but parchment paper helps with easy removal and prevents sticking, so it’s highly recommended.
