Ingredients
| Ingredient | Amount |
|---|---|
| Gluten-free sourdough starter (room temperature) | 150 grams |
| Unsalted butter | 35 grams |
| Oil (olive, grapeseed, or your favorite) | 10 grams |
| Whole psyllium husks | 1½ teaspoons (2 grams) |
| Dark brown sugar | 1 teaspoon |
| Kosher salt | ⅛ teaspoon |
| Smoked paprika (optional) | ⅛ teaspoon |
| Toppings (Everything Bagel Seasoning recommended) | As needed |
Instructions
Step 1: Preheat your oven to 325°F and line a baking sheet with parchment paper. This simple prep step makes cleanup a breeze and prevents any sticking drama later.
Step 2: Pop your butter into a microwave-safe bowl and melt it carefully—about 30 seconds should do it. Stir in the oil and set it aside to cool for a few minutes while you prep the rest.
Step 3: Grab a mixing bowl and combine your room-temperature sourdough discard, sugar, whole psyllium husks, kosher salt, and smoked paprika if you’re using it. Stir everything together until it looks completely uniform—no streaks allowed!
Step 4: Pour that cooled butter-oil mixture into your sourdough blend and stir until fully incorporated. The mixture should come together into a thick, spreadable dough that smells faintly tangy and absolutely amazing.
Step 5: Transfer your gluten-free cracker dough onto the prepared baking sheet. Using a small offset spatula (or the back of a spoon in a pinch), spread it into an even, thin layer about 13″ x 9″. Leave a bit of border around the edges—trust me, those outer crackers can go from golden to charcoal real quick.
Step 6: Sprinkle your chosen toppings evenly over the dough. I’m obsessed with Everything Bagel Seasoning, but flaky sea salt, rosemary, or even a sprinkle of parmesan works beautifully. Just don’t go overboard since the dough shrinks slightly as it bakes.
Step 7: Slide the pan into your preheated oven and bake at 325°F for exactly 20 minutes. Set a timer—this is where precision matters for crispy gluten-free sourdough crackers.
Step 8: After 20 minutes, lower the oven temperature to 300°F and continue baking until the crackers turn light golden brown—usually another 10-15 minutes, for a total bake time of 30-35 minutes. The crackers will firm up considerably as they cool, so don’t panic if they seem slightly soft when you first pull them out. Baking time varies based on your oven’s quirks and how thin you spread the dough.
Step 9: Let the crackers cool completely on the baking sheet before breaking them into pieces. If you’re worried about residual heat causing over-browning, carefully slide the parchment paper onto a cutting board or cool baking sheet. Complete cooling is essential for achieving that satisfying snap.
Substitutions
Can’t find whole psyllium husks at your local store? You can substitute with xanthan gum (about ½ teaspoon), though the texture won’t be quite as sturdy. Psyllium husks give these sourdough discard crackers their signature crisp texture and help bind everything beautifully.
If you’re dairy-free, swap the butter for more oil or use your favorite plant-based butter substitute. I’ve tested this with coconut oil and it works wonderfully, adding a subtle tropical note that pairs surprisingly well with savory toppings.
The dark brown sugar can be replaced with coconut sugar or regular granulated sugar in a pinch. The molasses notes from brown sugar add depth, but honestly, these crispy gluten-free sourdough crackers are delicious either way.
Troubleshooting
Are your crackers turning out chewy instead of crispy? You probably spread the dough too thick or didn’t bake them long enough. Remember, they’ll crisp up during cooling, but they should look dry and golden when you remove them from the oven.
If the edges are burning while the center stays pale, your dough layer is uneven. Take an extra minute to spread it uniformly—your offset spatula is your best friend here. Also check that you’re not spreading all the way to the pan edges.
Crackers breaking into dust instead of satisfying shards? They’re overbaked, friend. Every oven runs differently, so start checking at the 25-minute mark and adjust your timing for the next batch.
Storage
Store your cooled crackers in an airtight container at room temperature for up to two weeks. They’ll maintain their crunch beautifully if you keep moisture out—I like using a glass jar with a tight-sealing lid.
For longer storage, freeze them in a freezer-safe bag for up to three months. Let them come to room temperature before serving, and they’ll taste freshly baked. No need to re-crisp them—they bounce back perfectly on their own.
Serving Suggestions
These homemade gluten-free sourdough crackers are absolute showstoppers on a cheese board. Pair them with sharp cheddar, creamy brie, or tangy goat cheese for an impressive appetizer spread that’ll have guests asking for the recipe.
Man, oh man, they’re also perfect for dipping! Try them with hummus, spinach artichoke dip, or even your favorite Italian-style meatloaf for a gluten-free dipper option. My kids love crushing them over soup for a crunchy topping that beats store-bought croutons any day.
Variations
Kid-Friendly Version: Skip the smoked paprika and use cinnamon-sugar as your topping instead of everything bagel seasoning. You’ll create a sweet cracker that’s perfect for lunchboxes or afternoon snacks with apple slices.
Dairy-Free Adaptation: Replace the butter with additional olive oil (total of 45 grams oil) or use vegan butter. The texture stays wonderfully crisp, and you won’t miss the dairy one bit.
Herb Garden Variation: Mix dried rosemary, thyme, and oregano directly into the dough for an aromatic twist. Top with coarse sea salt and watch them disappear at your next holiday gathering—they’re especially popular during Thanksgiving appetizer hour.
Spicy Kick: Add ¼ teaspoon cayenne pepper to the dough and top with red pepper flakes. These are dangerously addictive with beer or margaritas at your next backyard barbecue.
Gluten-Free Sourdough Discard Crackers FAQs
Can I use cold sourdough starter straight from the fridge?
You can, but room temperature starter incorporates more easily and creates a smoother dough. Let it sit out for about 30 minutes before starting if yours is refrigerated.
What’s the best way to get uniformly thin crackers?
Place a second sheet of parchment on top of your dough and use a rolling pin to achieve even thickness. Remove the top parchment before adding toppings and baking—it’s like magic for consistent results.
How do I know when the gluten-free sourdough discard crackers are done?
They should look dry and lightly golden all over, with slightly darker edges. Remember that they firm up significantly while cooling, so slight softness in the center is okay when you first remove them.
Why do my crackers taste bland?
You might need more salt or toppings. Gluten-free sourdough discard crackers benefit from generous seasoning since the base dough is intentionally neutral to let your chosen flavors shine.
Can I make these without psyllium husks?
While possible, I don’t recommend it for the best texture. Psyllium husks provide crucial structure and that satisfying snap. Check out expert gluten-free baking resources for more details on why this ingredient matters.
