Line two baking sheets with parchment paper and set aside
Cut the apple into thin slices
Spread the apple slices on the baking sheets, making sure you have no overlapping edges (if they overlap, they’ll stick to each other and they won’t dry properly)
Sprinkle some seasonings on top and place in the oven
Place in the oven to bake for 1 hour; then flip the slices and cook for another hour
