2 tbsp cinnamon
1/4 tsp salt
Preheat the oven to 200 degrees and line a baking sheet with parchment paper.
Cut out the core of each apple and carefully cut the apple into even slices. Consider cutting the apple into thinner slices so they won't take as long to bake.
Lay the apple slices onto the baking sheet and sprinkle it with the salt and cinnamon.
Bake the apple slices for 3 to 4 hours or until the slices have started to curl.
