Preheat your oven to 350°F (180°C) and line a baking sheet with parchment paper.
In a mixing bowl, combine the all-purpose flour, sourdough starter, olive oil, salt, garlic powder, and dried herbs. Mix until a dough forms.
Turn the dough out onto a lightly floured surface and knead gently for about 1-2 minutes until the dough is smooth.
Roll the dough out to approximately ⅛-inch thickness using a rolling pin. Aim for an even thickness for consistent baking.
Cut the rolled dough into desired shapes using a sharp knife or pizza cutter. Place the cut crackers onto the prepared baking sheet.
If desired, sprinkle additional salt over the crackers for extra flavor.
Bake in the preheated oven for 20-25 minutes, or until the crackers are golden brown and crispy.
Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
