01 - Preheat oven to 300°F (150°C). Line a baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, combine the chia seeds, sunflower seeds, pumpkin seeds, sesame seeds, flaxseeds, sea salt, garlic powder, and dried herbs. Toss until evenly distributed.
03 - Pour the water into the seed mixture and stir thoroughly. Allow the mixture to rest for 10 minutes so the chia and flaxseeds absorb the liquid and form a thick, gel-like consistency.
04 - Transfer the thickened mixture onto the parchment-lined baking sheet. Using a spatula or the back of a spoon, spread it as thinly and evenly as possible, approximately 1/8 inch thick.
05 - Lightly score the spread mixture with a knife or pizza cutter to mark where the crackers will be separated after baking. This step ensures clean, even breaks.
06 - Bake for 1 hour, rotating the baking sheet halfway through to ensure even browning. The crackers are done when the edges are golden brown and the surface feels firm and crisp. If needed, bake for an additional 10 minutes.
07 - Remove from the oven and allow the sheet of crackers to cool completely on the pan. Once cool, break apart along the scored lines into individual crackers.
08 - Transfer cooled crackers to an airtight container. Store at room temperature for up to one week.
