Step 3: Bake the chips for an hour and a half. Remove from the oven, carefully flip with your fingers or a spatula, and sprinkle the new side with spices. Put the chips back in the oven for another hour. When the hour is up, check on the chips. If they are about as crispy as you want them, turn the oven off and keep the chips in the oven as it cools down. This will allow them to reach maximum crunchiness. If you prefer softer, chewier apple chips, reduce the baking time and pull them out when they have reached your desired consistency. Store in an airtight container at room temperature for up to one week. Keep the extra spice blends in an airtight container as well, and use them in your favorite fall recipes.
