Ingredients for sourdough discard cheese crackers
Pantry staples meet zero-waste magic for crispy, cheesy crackers that taste better than anything store-bought.
| Ingredient | Amount | Notes |
|---|---|---|
| Sourdough Discard 🍞 | 1 ½ cups | Active discard from starter |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, not pre-shredded |
| All-Purpose Flour 🌾 | 1 cup | For extra structure |
| Baking Powder 🧂 | ½ tsp | For lightness |
| Salt 🧂 | ½ tsp | Enhances cheddar flavor |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crispiness |
| Water 💧 | 1 tbsp | Hydrates discard |
| Fresh Rosemary 🌿 | 1 tsp | Chopped, optional |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Cornstarch 🌽 | 1 tbsp | Prevents sticking |
| Sesame Seeds 🌰 | 1 tbsp | For garnish, optional |
The sourdough discard is the star here—it needs to be active (bubbly and alive), so grab it from your starter before it gets too thick. Whole Foods or local bakeries often give it away for free if you ask nicely. For the cheddar, Kraft or Cabot work great, but avoid pre-shredded (it has anti-caking agents that prevent melting). If you're feeling fancy, swap in Parmigiano-Reggiano for a nutty twist. The flour is just for structure—if you're gluten-free, swap for a 1:1 GF blend. Rosemary is optional but adds a lovely aroma—Trader Joe's sells it pre-chopped for convenience.
No rosemary? Dried thyme or smoked paprika works just as well. Short on cornstarch? A light dusting of all-purpose flour on the baking sheet does the trick. The olive oil is key for crispiness—don’t skimp on quality here. If you’re making these for a crowd, double the batch and bake in two rounds. For extra crunch, sprinkle a pinch of garlic powder on the unbaked crackers. And if you’re feeling adventurous, try adding sun-dried tomatoes or jalapeños to half the dough for a spicy kick.
These crackers stay crisp for 3-4 days in an airtight container, but honestly, they disappear faster than that. For longer storage, freeze them on a tray first, then transfer to a bag—up to 1 month frozen. Reheat in a toaster or oven for 30 seconds to revive crispiness. Portion into small bags for gifting—everyone loves a zero-waste snack!

Step-by-step instructions for sourdough discard cheese crackers
Here's how to transform discard into crispy, cheesy perfection with just a few simple steps.
Mix the Dough for Perfect Texture
In a large mixing bowl, combine the 1.5 cups sourdough discard with the 1 cup all-purpose flour. This combination gives you the ideal balance of tangy flavor and structure. Add the 2 tbsp extra-virgin olive oil and 1 tbsp water, then mix until everything comes together into a shaggy dough.
Next, fold in the 2 cups shredded sharp cheddar cheese (I like to use my hands for this—it helps distribute the cheese evenly). Sprinkle in the 0.5 tsp baking powder, 0.5 tsp salt, 0.25 tsp black pepper, and 1 tsp chopped fresh rosemary. Mix thoroughly until the cheese is fully incorporated and the dough is smooth. If it feels too sticky, add 1 tbsp cornstarch at a time until it holds together when pressed.
Here's the thing—this dough should be firm but pliable. If it crumbles when you press it, add just a little more water, 1 teaspoon at a time, until it comes together. The goal is a dough that's easy to handle but won't stick to your fingers.
Roll and Cut for Uniform Crackers
Lightly flour a clean surface and turn out the dough. Gently pat it into a ½-inch thick rectangle about 8x10 inches. Wrap it tightly in plastic wrap and refrigerate for at least 30 minutes. This chilling step is crucial—it firms up the dough so it's easier to roll out evenly and prevents spreading during baking.
After chilling, remove the dough from the fridge and place it between two sheets of parchment paper. Using a rolling pin, roll it out to ⅛-inch thickness. I like to use a ruler to check the thickness—consistency is key for even baking. If the dough resists, let it sit at room temperature for 5-10 minutes to soften slightly.
Once rolled, use a 3-inch round cutter (or a glass of that size) to cut out circles. Place them on a parchment-lined baking sheet, spacing them about ½ inch apart. This gives them room to expand slightly during baking without touching. If you don't have a cutter, a knife works in a pinch—just dip it in flour between cuts to prevent sticking.
Bake Until Golden and Crisp
Preheat your oven to 350°F. This moderate temperature ensures the crackers bake through without burning. While the oven heats, sprinkle the crackers lightly with 1 tbsp sesame seeds on one side—this adds texture and a nutty flavor. You can also brush the tops with a tiny bit of extra-virgin olive oil for extra crispiness if you like.
Bake for 12-15 minutes, rotating the tray halfway through, until the edges are golden brown and the crackers look completely dry. They should pull away from the parchment paper slightly at the edges. If you press down gently with your finger, they should feel firm and crisp—not soft or doughy. Here's where patience pays off: resist the urge to peek early. The crackers need time to fully set.
Remove from the oven and let cool on the baking sheet for 10 minutes. This resting period allows them to crisp up completely. If you try to move them too soon, they'll bend or soften. Once cooled, transfer to a wire rack to finish cooling completely. The contrast in temperature helps them achieve that perfect snap.
Pro Tips For Making Sourdough Discard Cheese Crackers
- Chill the Dough: After mixing, pop the dough in the fridge for 30 minutes—yes, even if you’re eager to bake. I used to skip this and ended up with crackers that spread like pancakes instead of holding their shape. Cold dough behaves better when you roll it out, and the cheese melts more evenly.
- Grate Cheese Fine: Sharp cheddar has big chunks that don’t melt smoothly. Pulse it in a food processor for 10 seconds or grate it yourself—you want it almost powdery. I learned this the hard way when my first batch had chewy, unmelted cheese bits. Trust me, it’s worth the extra minute.
- Roll Thin, Even Layers: Aim for ⅛-inch thickness—thinner than you think. Use a rolling pin with a guide or a ruler to check. Uneven thickness means some crackers burn while others stay doughy. (And no, "thin enough" isn’t a real measurement—measure it.)
- Bake in Batches: Overcrowding the tray steams the crackers instead of crisping them. Leave at least 1 inch between them, and bake in two batches if needed. I used to jam them on like a lazy baker, and they’d come out soft and sad. A little patience = perfect crunch.

Frequently asked questions
Can I use pre-shredded cheese in this recipe?
No, pre-shredded cheese contains anti-caking agents that prevent proper melting, leading to a grainy texture in your crackers. Always use freshly shredded sharp cheddar for the best flavor and melt. If you must use pre-shredded, pulse it a few times in a food processor to break up the additives.
Why did my crackers turn out soft instead of crispy?
Overly thick dough or underbaking are the most common causes. Roll the dough to ⅛-inch thickness and bake until edges are golden brown (12-15 minutes at 350°F). Let them cool completely on the baking sheet before transferring—they crisp up as they cool. For extra crunch, brush baked crackers with melted butter or olive oil.
How do I store these crackers to keep them crisp?
Store in an airtight container at room temperature for up to 3-4 days. For longer storage, freeze them on a tray first, then transfer to a bag. Reheat in a toaster or oven for 30 seconds to revive crispiness. Never store in plastic bags—they'll sweat and soften quickly.
Can I make these crackers gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). You may need 1 extra tablespoon of cornstarch to help bind the dough. Test with a small batch first, as GF flours vary in texture. The crackers will still be crispy but may have a slightly denser center.
What's the best way to use up extra sourdough discard?
These crackers are perfect for using 1.5 cups of active discard, but you can also try: sourdough discard pancakes, cheesy sourdough muffins, or discard flatbread. For maximum flavor, use discard that's bubbly but not too thick—if yours is stiff, add 1-2 tablespoons of water to loosen it.
