Preheat your oven to 325°F (160°C). Line a large baking sheet with parchment paper or a silicone baking mat.

In a mixing bowl, combine the almond flour, chia seeds, nutritional yeast (if using), garlic powder, onion powder, sea salt, and black pepper. Add the olive oil and mix until the ingredients resemble coarse crumbs. Gradually stir in the water, one tablespoon at a time, until the dough comes together into a firm but pliable ball.

Place the dough between two sheets of parchment paper. Use a rolling pin to roll it out thinly and evenly (about ⅛ inch thick). If desired, sprinkle additional chia seeds, sesame seeds, or herbs on top and gently press them into the dough.

Use a pizza cutter, sharp knife, or cookie cutters to slice the dough into squares, rectangles, or any shape you like. Transfer the parchment paper (with the cut dough) onto the prepared baking sheet. Prick each cracker with a fork to prevent puffing during baking.

Bake in the preheated oven for 15–20 minutes, or until the edges are golden brown and the crackers are crisp. Rotate the baking sheet halfway through baking to ensure even cooking.

Remove the crackers from the oven and let them cool completely on the baking sheet. They will continue to crisp up as they cool. Once cooled, break apart any crackers that may have stuck together. Store in an airtight container at room temperature for up to 1 week.
