Oven or toaster oven
Cookie sheet or aluminum foil
There are few things more frustrating than reaching your hand into a bag of chips in anticipation of the crunchy texture, only to find they have become soft and stale. Although you won't get that instant chip gratification, you can use a relatively quick trick to restore the freshness of your snack and satisfy your craving.
Preheat your oven to 350 degrees Fahrenheit or your toaster oven to 300 F.

Spread the stale chips in a single layer on a cookie sheet or piece of aluminum foil, maintaining space between each chip.
Put the chips into the preheated oven on the center rack so the heat can remove the moisture that makes the chips soft and stale. Sample a chip after 3 minutes to check for the desired level of crunch. Keep baking for an additional 1 to 2 minutes if necessary.
Restoring the freshness of chips in the oven works for any type of chip, from potato to corn.
Inspect the chips for mold and discard them if you find it. Always use an oven mitt when handling hot items.
