That jar of sourdough discard sitting in your fridge is about to become your favorite snack.
Sourdough discard crackers seeded everything bagel style take under 40 minutes from bowl to crunch, with no rolling pin required.
The tangy discard does all the flavor work here.
Every bite delivers that signature sour note you love from your starter, layered under salty, seedy everything bagel seasoning.
Why This Recipe Stands Out
- No added flour required: The discard bakes directly into a crispy sheet, keeping the crackers fully fermented and gut-friendly.
- Three core ingredients: Sourdough discard, melted unsalted butter, and everything bagel seasoning are all you need for a complete savory snack.
- No rolling pin or cutting needed pre-bake: You spread the batter with a spatula, score it mid-bake, and break it apart once cooled.
- Cold discard works: You can pour it straight from the fridge without bringing it to room temperature first, saving extra prep time.
- Deeply layered flavor: Sesame seeds, poppy seeds, dried garlic, dried onion, and flaky salt in the seasoning create a savory complexity far beyond a basic cracker.
Tips for Success
- Spread as thin as possible: Aim for a layer around 1-2mm thick across the parchment. Thinner spread equals crispier crackers with a better snap.
- Use unsalted butter: Everything bagel seasoning already carries significant salt. Salted butter pushes the crackers into an overwhelming brine.
- Score mid-bake, not before: Score the partially baked sheet at the 10-minute mark. The surface sets enough to hold clean lines without tearing.
- Use discard no older than 10 days: Fresher discard gives a brighter tang and more active flavor. Very old discard can produce an unpleasant acidic edge.
- Rotate the pan halfway through: Ovens heat unevenly. Rotating at the 20-minute mark prevents one side browning faster than the other.
- Cool completely before breaking: Crackers continue to crisp as they cool. Breaking them while warm causes soft, bendy pieces instead of a clean snap.
Common Mistakes to Avoid
- Spreading the batter too thick: A thick layer traps steam during baking. This results in crackers that are soft and chewy rather than crispy and snappable.
- Skipping the parchment paper: Batter poured directly onto a bare pan sticks aggressively to the metal. Removing it without parchment breaks the crackers into unusable fragments.
- Adding seasoning before spreading: Seasoning the batter before it hits the pan causes the seeds to sink and burn against the hot surface. Always add the seasoning on top after spreading.
- Opening the oven too early: Checking the crackers before the 10-minute score point disrupts the even bake. The surface needs uninterrupted heat to set before scoring.
- Pulling crackers too early: Pale crackers that look set are often still soft underneath. Wait until the edges are deep golden and the surface looks dry and matte before removing from the oven.
Creative Serving Ideas
- Smear with cream cheese and a thin cucumber slice: This mirrors the classic everything bagel topping and makes a satisfying two-bite snack or party appetizer.
- Float them on top of a creamy tomato soup: The crackers act as a seeded crouton, absorbing the broth slowly without fully dissolving, adding texture in every spoonful.
- Pair with a sharp cheddar and hot honey board: The salty, tangy cracker cuts through rich aged cheese, and the heat from honey creates a flavor contrast worth returning to.
- Use as a base for smoked salmon bites: Layer with a thin swipe of creme fraiche, a fold of smoked salmon, and a tiny caper for a low-effort appetizer that looks impressive.
- Pack into a lunchbox alongside hummus: The crackers hold up to thick dips without snapping apart, making them a sturdier alternative to store-bought rice crackers.
Frequently Asked Questions
Can I use active starter instead of discard?
Yes, active fed starter works in this recipe without any adjustments.
The flavor will be slightly milder than discard since active starter is less acidic.
Either version produces crispy crackers.
My crackers came out soft and bendy. What went wrong?
Soft crackers are almost always caused by spreading the batter too thick or pulling them from the oven too soon.
For sourdough discard crackers seeded everything bagel style, you need a very thin, even layer and a full bake until the edges are deep golden.
Return soft crackers to a 300F oven for 5-10 additional minutes to dry them out.
Can I make these gluten-free?
The base no-flour version of this recipe is naturally gluten-free if your sourdough starter is maintained with a certified gluten-free flour like rice flour or a GF blend.
Check that your everything bagel seasoning blend does not contain any wheat-based fillers.
Most commercial everything seasoning blends are gluten-free but always verify the label.
How do I store the crackers and how long do they last?
Store completely cooled crackers in an airtight glass jar or sealed container at room temperature.
They stay crispy for up to one week, though they rarely last that long.
You can also freeze them in an airtight bag for up to three months and reheat in a 300F oven for 5 minutes.
Can I make my own everything bagel seasoning?
Yes, combine equal parts white sesame seeds, black sesame seeds, poppy seeds, dried garlic flakes, dried onion flakes, and coarse sea salt.
Mix well and store in a jar at room temperature.
Use the same quantity called for in this recipe without any other adjustments.
Can I add seeds directly into the batter instead of just on top?
Absolutely. Mixing sesame seeds, poppy seeds, or hemp seeds directly into the batter before spreading adds extra texture throughout each cracker.
Use 2-3 tablespoons of mixed seeds stirred into the discard-butter mixture.
Still sprinkle the everything bagel seasoning on top after spreading for the full flavor crust.
Ingredients You’ll Need
- 1 cup (240g) sourdough discard, unfed
- 2 tablespoons unsalted butter, melted and slightly cooled
- 2 tablespoons everything bagel seasoning (store-bought or homemade)
- 1 tablespoon white sesame seeds
- 1 tablespoon black sesame seeds
- 1 tablespoon poppy seeds
- Flaky sea salt, for finishing (optional)
Tools to Use
- Large rimmed half-sheet baking pan
- Parchment paper
- Medium mixing bowl
- Rubber spatula or offset spatula
- Pizza wheel or sharp knife
- Wire cooling rack
How to Make Everything Bagel Seeded Sourdough Discard Crackers
Step-1: Preheat and Prepare the Pan
Set your oven to 325°F (160°C). Line a large rimmed half-sheet pan with parchment paper, pressing it flat against the corners.
Step-2: Mix the Batter
Add the sourdough discard and melted butter to a medium bowl. Stir firmly until the mixture is smooth and fully combined with no streaks of butter.
Fold in the white sesame seeds, black sesame seeds, and poppy seeds. Stir until the seeds are evenly distributed throughout the batter.
Step-3: Spread Thinly and Season
Pour the batter onto the prepared pan. Use an offset spatula to spread it into the thinnest, most even layer possible, working toward the edges of the parchment.
Sprinkle the everything bagel seasoning evenly over the top surface. Add a pinch of flaky sea salt if desired for extra crunch.
Step-4: First Bake
Place the pan in the preheated oven and bake for 10 minutes undisturbed. The surface will appear set and slightly dry around the edges when ready to score.
Step-5: Score the Crackers
Remove the pan carefully from the oven. Use a pizza wheel or sharp knife to score the baked sheet into rectangles or squares of your preferred size.
Work quickly and press firmly through the full thickness of the sheet. Do not worry if the score lines are not perfectly uniform.
Step-6: Second Bake
Return the pan to the oven and bake for another 20-25 minutes, rotating the pan halfway through.
Watch for deep golden-brown edges and a fully dry, matte surface.
Every oven runs differently, so begin checking at the 20-minute mark. Remove any crackers that are browning faster than the rest.
Step-7: Cool and Break Apart
Remove the pan from the oven and set it on a wire rack. Allow the crackers to cool completely, at least 15 minutes, before breaking along the scored lines.
The crackers crisp further as they cool. Rushing this step will result in soft pieces rather than the clean snap you are after.
