MATERIALS & SUPPLIES
Before we get mixing, let’s gather our tools and ingredients. The beauty of this recipe lies in its simplicity, but having everything ready makes the process seamless.
Ingredients & Seasonings:
- Active Sourdough Discard: 1 cup (240g). This is your star ingredient. It can be unfed and straight from the fridge—cold or room temp works fine.
- All-Purpose Flour: 1 cup (120g). This helps balance the hydration of the discard and adds structure. You can also use whole wheat or rye for a nuttier flavor.
- Olive Oil or Melted Butter: 2 tablespoons. This provides fat for tenderness and crispness. Avocado oil works great for a neutral flavor.
- Sea Salt: 1 teaspoon (plus extra for sprinkling). Adjust to taste; discard varies in saltiness.
- Water: 1–3 tablespoons. Depending on the hydration of your starter, you may need this to get a workable dough.
- Optional Add-ins: Dried herbs (rosemary, thyme), garlic powder, onion powder, sesame seeds, poppy seeds, or “Everything Bagel” seasoning.
Kitchen Tools:
- Large Mixing Bowl: To combine ingredients.
- Dough Scraper: Helpful for handling the sticky dough.
- Rolling Pin: To get the dough thin and even. If you don’t have one, a wine bottle wrapped in plastic works in a pinch!
- Parchment Paper: Essential for rolling out the sticky dough and transferring it to the baking sheet without tearing.
- Baking Sheet (Half Sheet Pan): Standard size.
- Pastry Brush or Spray Bottle: For oiling the dough.
- Pizza Cutter or Sharp Knife: For scoring the crackers before baking.
TIMING / COOKING SCHEDULE
- Prep Time: 10 minutes (plus optional resting time).
- Cook Time: 25–30 minutes.
- Total Time: 40 minutes.
- Schedule Notes: This is a very weeknight-friendly recipe. The active time is low, but the baking requires you to be nearby to rotate the pans for even browning. It’s perfect for a “hands-off” oven session while you tidy up the kitchen.
STEP-BY-STEP INSTRUCTIONS
- Preheat and Prep: Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper. If you skip the parchment, your crackers will stick—do not skip this!
- Mix the Dough: In a large bowl, combine the sourdough discard, flour, olive oil, and salt. Start mixing with a fork or spatula. It will look shaggy at first.
- Adjust Hydration: Add water, one tablespoon at a time, kneading gently in the bowl until the dough comes together. It should be tacky but not overly sticky. Tip: If your discard is very runny, you may need less water; if it’s thick, you might need more.
- Rest (Optional but Recommended): Let the dough sit for 15–20 minutes. This allows the flour to fully hydrate, making the dough easier to roll out. This isn’t strictly necessary for flavor, but it makes handling the dough much easier.
- Roll It Thin: Place the dough on your parchment paper. Place another sheet of parchment on top (this prevents sticking to the rolling pin). Roll the dough as thin as you possibly can—aim for 1/16th of an inch. The thinner, the crispier the Sourdough Discard Crackers will be. If you are making savory sourdough discard snacks, sprinkle your herbs and seeds now and roll them in gently.
- Score the Dough: Peel off the top layer of parchment. Use a pizza cutter or knife to score the dough into squares, rectangles, or diamonds. Don’t separate them; just score the surface. This ensures they break apart neatly after baking.
- Oil and Season: Brush the surface lightly with olive oil or melted butter. Sprinkle with flaky sea salt (and more herbs if you like).
- Bake: Bake for 10 minutes. Rotate the pan (turn it 180 degrees) and bake for another 10–15 minutes. Watch closely near the end! The crackers are done when they are golden brown and the edges are darker. They will crisp up as they cool.
- Cool Completely: Remove from the oven and let them cool on the baking sheet for 5 minutes, then transfer the parchment to a wire rack. Break them apart along your scored lines. They will get crunchier as they cool down.
NUTRITIONAL BENEFITS / ADVANTAGES
Making your own crackers at home isn’t just a fun project; it’s a health-conscious choice. When you cook from scratch, you eliminate the preservatives, artificial flavors, and excessive sodium found in many commercial crackers. You get pure, simple ingredients.
Furthermore, this recipe is a champion of sustainability. By using Sourdough Discard Crackers, you are actively reducing food waste. There is zero packaging waste compared to buying boxes of crackers, and you are utilizing the “byproduct” of your bread baking. It’s a small step toward a more eco-friendly kitchen. Plus, it’s cost-effective! Flour and water are inexpensive, turning a few cents of ingredients into a gourmet jar of snacks.
TIPS, ALTERNATIVE METHODS, OR COOKING ADVICE
One of the best things about making sourdough discard snacks is how versatile they are. Here are some ways to adapt the recipe:
- Flavor Variations: Mix 1/4 cup of grated parmesan cheese or sharp cheddar into the dough for a cheesy kick. For a sweet version, add a tablespoon of honey and cinnamon.
- Rolling Tips: If you don’t have a rolling pin, use a heavy-bottomed pot or a tall bottle. Just ensure it’s clean!
- Cutting Tools: If you want perfectly uniform shapes, a pastry wheel or a fluted pizza cutter adds a nice decorative edge.
- Texture Check: If your crackers are chewy rather than crunchy, they likely need another 5–10 minutes in the oven at a lower temperature (300°F) to dry out without burning.
COMMON MISTAKES TO AVOID
- Rolling Too Thick: The number one mistake is rolling the dough too thick. If it’s thick like a tortilla, it will be hard and dense. If it’s paper-thin, it will be crisp. Take your time rolling!
- Baking Without Parchment: Sticky dough and hot metal pans are a recipe for disaster. You will never get them off the pan intact without parchment.
- Overcrowding the Pan: If you double the batch, use two pans. Crowding one pan traps steam, leading to soggy crackers.
- Under-baking: Don’t be afraid of color! Pale crackers are usually soft crackers. You want them golden brown.
- Salty Starter: Taste your discard. If your starter is fed with salted water, reduce the added salt in the recipe to avoid an overly salty end product.
STORAGE / MAKE-AHEAD TIPS
These crackers are best eaten the day they are made for maximum crunch, but they store beautifully if kept dry.
- Cooling is Key: Ensure the crackers are completely cool before storing. Any residual heat will create steam in the container, resulting in soft, chewy crackers.
- Container: Store in an airtight container (a glass jar is ideal) at room temperature. Keep them in a cool, dry place away from humidity.
- Shelf Life: They will stay fresh and crunchy for up to 2 weeks.
- Refresh: If they lose their crunch, pop them back into a 300°F oven for 3–5 minutes to re-crisp them.

FAQs
1. Can I use my sourdough starter if it hasn’t been fed recently?
Yes! This is the perfect recipe for unfed, “discard” starter. It doesn’t need to be active or bubbly.
2. My dough is too sticky to roll. What should I do?
Add a little more flour, one tablespoon at a time, until it’s manageable. However, keep in mind that a soft dough results in tender crackers.
3. Are these crackers gluten-free?
Not as written. If you need a gluten-free version, you can substitute the all-purpose flour with a gluten-free all-purpose blend, but the texture may vary slightly.
4. Can I make these in an air fryer?
Yes, but you must work in very small batches. Roll the dough out on parchment, score it, and place the parchment inside the air fryer basket. Cook at 320°F for about 6–8 minutes, watching carefully to prevent burning.
5. Why are my crackers chewy?
They likely need more time in the oven to dry out. If the edges are browning too fast but the centers are chewy, lower the oven temperature to 300°F and bake for an additional 10–15 minutes.
