- Butter: Adds richness and helps create a tender, flaky texture.

How to Make Gluten Free Sourdough Crackers Step-by-Step Instructions
1. Prepare Your Workspace
Preheat your oven to 350°F. Line two baking sheets with parchment paper. This prevents sticking and makes cleanup easy.
2. Mix the Dough
In a large bowl, combine the gluten-free sourdough discard with softened butter. Mix until well combined. Add sea salt, black pepper, and psyllium husks. Stir everything together until you have a smooth dough.
3. Roll Out the Dough
Place the dough between two sheets of parchment paper. Roll it out very thin, about 1/8 inch thick. The thinner you roll it, the crispier your crackers will be.
4. Add Toppings
Remove the top parchment paper. Sprinkle flaky sea salt, sesame seeds, and poppy seeds evenly over the surface. Gently press them into the dough with your rolling pin.
5. Cut the Crackers
Use a sharp knife or pizza cutter to cut the dough into small squares or rectangles. Make them about 2 inches wide. You can make them smaller or larger based on your preference.
6. Bake the Crackers
Carefully transfer the cut crackers to your prepared baking sheets, leaving small spaces between each piece. Bake for 20-25 minutes until the edges are golden brown and the crackers look crispy.
7. Cool and Crisp
Let the crackers cool on the baking sheet for 5 minutes, then transfer to a wire rack. They will get crispier as they cool.

How to Serve Gluten Free Sourdough Crackers
These versatile crackers work well in many ways:
- Cheese Board: Pair with soft cheeses like brie or sharp cheddar.
- Dip Companion: Serve with hummus, spinach dip, or guacamole.
- Soup Topper: Crumble over tomato soup or butternut squash soup.
- Salad Croutons: Break into pieces and add to salads for extra crunch.
- Snack Time: Eat them plain as a healthy snack option.
- Gift Giving: Package in pretty bags as homemade gifts.
Storing Gluten Free Sourdough Crackers
- Room Temperature: Store in an airtight container for up to 1 week. Keep them crispy by adding a silica gel packet if you have one.
- Freezer Storage: Freeze for up to 3 months in a freezer-safe container. Thaw at room temperature before serving.
- Re-crisping: If crackers get soft, bake them at 300°F for 5 minutes to restore crispness.
Tips and Tricks for Success
- Roll Thin: The thinner you roll the dough, the crispier your crackers will be.
- Even Thickness: Try to keep the thickness even so all crackers bake at the same rate.
- Don’t Overbake: Watch carefully in the last few minutes. Golden brown edges mean they’re done.
- Cool Completely: Let crackers cool completely before storing to maintain crispness.
- Use Fresh Discard: Fresher sourdough discard gives better flavor than very old discard.
