A Personal Note
As we work toward cutting out processed and prepackaged foods from our diet, I’ve found that school snacks have been one of the trickiest things to replace. Oliver’s snacks are fairly healthy, but there were a few I knew I needed to swap out. Since vegetable crackers are one of his favorites, I had to come up with a tasty alternative to get his approval.

Recipe Tips
Roll Thin: The thinner the dough, the crispier the crackers. Aim for about 1/8 inch thick.
Use Parchment Paper: Rolling the dough between two sheets of parchment prevents sticking and makes transferring easier.
Even Scoring: Score the dough with a pizza cutter before baking to make it easier to break into uniform pieces.
Customize the Flavor: Try garlic powder, dried herbs, black pepper, or grated cheese for extra flavor.
Watch for Browning: Crackers on the edges may brown faster—remove them early if needed and continue baking the rest.
Storage: Keep in an airtight container at room temperature for up to a week. Refresh in the oven if they soften.

How to Make Flakey Sourdough Discard Crackers
Preheat & Prepare: Preheat your oven to 325°F (163°C) and line a baking sheet with parchment paper.
Mix the Dough: In a bowl, combine the sourdough starter, all-purpose flour, melted butter, and fine sea salt. Mix until a stiff dough forms, adding water 1 tablespoon at a time if needed to bring the dough together.
Roll Out: Transfer the dough to a lightly floured surface and roll it out as thin as possible (about 1/8 inch thick). Move the dough onto the prepared baking sheet.
Add Seasonings & Score: Lightly brush the surface with water, then sprinkle your desired seasonings. Use a knife or pizza cutter to score the dough into squares or rectangles.
