Preheat your oven to 250°F and line a baking sheet with parchment paper. I managed to fit 6 slices of cheese (cut into 9 pieces each) on my baking sheet, yielding 54 mini crackers, but feel free to adjust the size to your preference. Bake for 30-35 minutes, then remove them from the oven and let them cool. My husband and I nearly finished them all in one go!
