Sourdough Cheddar Snack Crackers

The tang of sourdough discard hit me one Tuesday evening as I stared into the jar, wondering what on earth to do with the growing mound of sleepy starter.

My neighbor Dave knocked on the door last winter while a tray of these was cooling, and I ended up sending him home with half the batch and the recipe scribbled on a napkin.

Ingredients

• Sourdough discard (1 cup, unfed, room temperature): This is the soul of the cracker, giving it that signature tang without any extra effort on your part.
• Sharp cheddar cheese (1 cup, finely shredded): Go for the sharpest you can find because the oven mellows it and you want that cheese flavor to hold its ground.
• All-purpose flour (3/4 cup): Just enough to bind everything without turning these into something bready.
• Unsalted butter (2 tbsp, softened): A little fat goes a long way toward that snap when you bite in.
• Sea salt (1/2 tsp): Balances the tang and the richness of the cheese.
• Garlic powder (1/2 tsp, optional): A quiet background note that makes people ask what your secret is.
• Smoked paprika (1/4 tsp, optional): Adds a whisper of smoke that pairs beautifully with the cheddar.
• Cold water (1 to 2 tbsp): Only if the dough needs help coming together, add it sparingly.
• Coarse sea salt for topping: Those little crystals on top make each cracker feel like it came from a bakery.

Instructions

Set up the oven:

Preheat to 350 degrees F and line a baking sheet with parchment paper so nothing sticks and cleanup is effortless.

Bring the dough together:

In a mixing bowl, stir together the sourdough discard, shredded cheddar, softened butter, salt, garlic powder, and paprika until everything is well incorporated and looks like a thick paste.

Add the flour:

Gradually mix in the flour until a shaggy dough forms, then sprinkle in cold water one tablespoon at a time just until it holds together in a ball.

Knead briefly:

Turn the dough onto a floured surface and knead gently until smooth, maybe eight or ten turns, being careful not to overwork it.

Roll and cut:

Roll the dough out to about 1/8 inch thickness and use a sharp knife or pizza cutter to slice it into neat one inch squares.

Prepare for baking:

Transfer the squares to your lined baking sheet, prick each one once or twice with a fork, and finish with a generous sprinkle of coarse salt.

Bake until golden:

Bake for 16 to 20 minutes, rotating the tray halfway through, until the edges turn a deep golden and the kitchen smells like a cheese shop.

Cool and store:

Let the crackers cool completely on a wire rack so they crisp up properly, then store them in an airtight container where they stay crunchy for up to a week.

That winter evening with Dave turned into a standing tradition where he shows up every few weeks with a block of cheddar and I supply the discard.

Serving Ideas Worth Trying

These crackers are wonderful on their own but truly shine when you serve them alongside a bowl of tomato soup or a smear of good hummus.

Storing for Maximum Crunch

Airtight is the only way to go here, and I learned that lesson after leaving a batch out overnight and finding sad soft squares by morning.

Getting Creative With Flavors

The base recipe is a playground, and once you are comfortable with the dough you can start riffing with whatever sounds good.

• Fold in a tablespoon of chopped fresh chives or thyme for an herby twist.
• Add a pinch of cayenne if you want a slow warmth that builds with each cracker.
• Always write down what you changed so you can recreate the version everyone liked best.

Every time I open the fridge and see that jar of discard, I no longer sigh at the chore of feeding it.

Your Recipe Questions Answered

→ Do I need unfed sourdough discard?

Unfed discard is ideal because it's drier and has a bright tang that concentrates flavor. If you only have fed starter, reduce added water and increase flour slightly, then chill the dough briefly to make it easier to roll.

→ How thin should I roll the dough?

Roll to about 1/8-inch (3 mm). Thin dough yields crisp crackers; thicker pieces stay softer and may need longer baking. Use a ruler or visual guide to keep thickness even for uniform browning.

→ How can I keep the crackers crisp after baking?

Cool completely on a wire rack to release steam, then store in an airtight container at room temperature. Add a small paper towel to absorb residual moisture and avoid storing in humid areas.

→ What cheeses work instead of sharp cheddar?

Aged gouda, Parmesan, or a sharp white cheddar all work well. Harder, drier cheeses give better structure and less spreading; adjust salt if using salty aged cheeses.

→ How can I vary the flavor?

Fold in chopped herbs like chives or thyme, a pinch of cayenne for heat, or seeds such as sesame or poppy. You can also sprinkle flaky salt, smoked paprika, or nutritional additives before baking for a different profile.

→ Can I make these gluten-free?

Use a cup-for-cup gluten-free flour blend with a binder (xanthan gum if not included) and watch hydration—some blends absorb more liquid. The texture will differ but rolling thin and careful handling help achieve crispness.
