Topping options:
Preheat your oven to 350 F (175 C).
Add your sourdough discard to a bowl with the melted butter, salt, and parmesan cheese. Stir everything to combine well or until the butter is mixed into the dough.
Line a sheet pan with parchment paper and then dump the mixed discard on top. Spread the discard mixture into a thin layer on top of the parchment. The thinner you spread the mixture, the crispier the finished cracker bread will turn out.
Sprinkle on any toppings like cheese, black pepper, or even sesame seeds, and then bake for 15 to 20 minutes. The bake time can vary depending on how thin you spread the mixture. The crackers should be done in around 15 minutes, but you can bake them a little bit longer to get more color and to make them a little bit crispier. If I felt like I spread some parts really thin, then I would check and rotate the pan 180 degrees at the 10-minute mark just to see how much color it's taking on. If at 10 minutes there are already some pretty dark spots, you may want to remove them sooner than 15 minutes.
If you want to make these extra crispy, remove the crackers from the parchment after they finish baking and put them back into the cooling oven directly on the oven rack for about 5 minutes. This will crisp up the bottom and the top.
