Set your oven to 350°F (176°C) and line a baking sheet with parchment paper.

In a bowl, combine the sourdough discard, melted butter, and sea salt. Stir until smooth.

Pour the mixture onto the prepared baking sheet. Use a spatula or offset knife to spread it thin and evenly.

Sprinkle everything bagel seasoning evenly over the top.

Place in the oven and bake for 10 minutes. After 10 minutes remove them from the oven, using a knife or pizza cutter lightly score the dough into cracker shapes to make breaking them apart easier after baking.

Place in the oven for an additional 20-30 minutes, or until the crackers are golden brown and crisp.

Let the crackers cool completely before breaking them along the scored lines.

Serve immediately or store in an airtight container for later.
