Sourdough Cheddar Snack Crackers

The Tuesday my sourdough starter nearly overflowed its jar, I tossed a cup of discard into a cheddar biscuit dough just to use it up, and what came out of the oven was something between a cracker and a tiny cheese comet that vanished before dinner. Those crispy, tangy little squares became an obsession I never planned on. Now I keep a tub of discard in the fridge specifically to make these.

My neighbor stopped by one afternoon while a batch was cooling and stood in the kitchen eating them straight off the parchment, burning her fingers and not caring one bit.

Ingredients

• All-purpose flour (120 g, 1 cup): The sturdy base that holds everything together without making the crackers tough.
• Sourdough discard (100 g, 1/2 cup, unfed, 100% hydration): This is the secret weapon, adding tang and a slight lift that makes each cracker memorable.
• Unsalted butter (115 g, 1/2 cup, cold and diced): Cold butter creates those irresistible flaky layers, so keep it chilled until the last second.
• Sharp cheddar cheese (120 g, 1 cup, lightly packed, grated): Go sharp, not mild, because the oven tones down the intensity and you want that cheese punch to survive.
• Fine sea salt (1/2 tsp): Balances the tang of the discard and the richness of the butter.
• Garlic powder (1/4 tsp, optional): A quiet background note that makes people ask what is in these.
• Smoked paprika (1/4 tsp, optional): Adds a whisper of smoke that pairs beautifully with sharp cheddar.
• Flaky sea salt for topping: That final crackle on top is what makes these feel bakery-worthy.

Instructions

Pulse the dry ingredients together:

Drop the flour, fine sea salt, garlic powder, and smoked paprika into your food processor and give it several quick pulses until everything is evenly mixed and airy.

Cut in the cold butter:

Add the diced butter and pulse until the mixture looks like coarse sand with a few pea-sized bits remaining for texture.

Add the cheddar:

Toss in the grated cheese and pulse just enough to distribute it evenly through the mixture without turning it into paste.

Bring in the sourdough discard:

Add the discard and pulse until the dough just comes together in a cohesive ball, stopping before it gets overworked.

Chill the dough:

Turn the dough out onto a lightly floured surface, shape it into a flat disc, wrap it tightly in plastic, and let it rest in the fridge for at least 30 minutes.

Prep the oven and sheets:

Heat your oven to 180°C (350°F) and line two baking sheets with parchment paper so nothing sticks.

Roll and cut:

Roll the chilled dough to about 3 mm thick, then use a knife or pizza cutter to slice it into 2.5 cm squares, transferring them to your prepared sheets.

Prick and salt:

Give each cracker a quick fork prick to keep it flat, then finish with a light sprinkle of flaky sea salt.

Bake until golden:

Bake for 20 to 25 minutes, rotating the trays halfway through, until the edges are deeply golden and the centers look crisp.

Cool completely:

Let them cool on the sheets because they continue crisping as they sit, and warm crackers will soften in a storage container.

Packing these into a tin for a road trip made me realize they had become part of how I show care, a small crunchy love letter.

What to Serve With These Crackers

They are sensational on a cheese board beside grapes, honey, and something with a bloom rind, but honestly my favorite pairing is a lazy afternoon and nothing else.

Storing and Keeping Them Crisp

An airtight container at room temperature keeps them crunchy for about a week, though in my house they rarely last three days.

Mixing It Up With Variations

Once you master the base recipe, the flavor possibilities open wide and it becomes hard to stop experimenting.

• A pinch of cayenne turns them into something unexpectedly addictive with a slow, warming hum.
• Swapping cheddar for Gruyère gives a nutty, sophisticated edge perfect for entertaining.
• Try half Parmesan and half cheddar for an intensely savory cracker that pairs beautifully with soup.

Every time my starter needs feeding now, I catch myself grinning because it means another batch of these golden little squares is close behind.

Recipe FAQs

→ Can I use fed starter instead of discard?

Yes, but fed starter is more hydrated and active. Use slightly less starter or add a touch more flour, chill the dough longer, and expect a slightly different tang and texture.

→ How do I make the crackers extra crunchy?

Roll the dough thin (about 3 mm), prick each square to release steam, and bake until golden. Let them cool completely on a rack—crispness improves as they dry.

→ What cheeses work well as substitutes?

Sharp cheddar is classic, but Gruyère, aged Parmesan, or a tangy manchego add depth. Use flavorful, dry cheeses for the best texture and taste.

→ How should I store leftover crackers?

Cool fully, then store in an airtight container at room temperature for up to a week. Separate layers with parchment to avoid moisture buildup; they may lose crispness in humid conditions.

→ Can I make a gluten-free version?

Yes—use a gluten-free all-purpose blend that contains xanthan or guar. The dough will be more fragile; chill thoroughly and handle gently when rolling and cutting.

→ Why is chilling the dough important?

Chilling firms the butter and hydrates the flour, yielding a flakier texture and preventing excessive spreading during baking. It also makes the dough easier to roll thin.
