Cheese curls and other snack foods are crunchy because they are very dry. This state can be difficult to maintain. If you leave an open bag of cheese curls out or do not seal it properly, moisture in the air can get into the bag and change the composition of the chips. As the chips soak up moisture from the air, they get stale or lose their crunch. If you accidentally left your cheese curls out overnight and find that they have lost their crunch, it is easy to revive your snack.
Things You'll Need

Spread your cheese curls out on a baking sheet.
Bake in the oven for 3-5 minutes, watching closely to prevent the cheese curls from burning.
