When the package gets left open, you can end up with not so crisp crackers. This guide contains uses for stale crackers.
Rescue stale or soggy chips and crackers by preheating the oven to 300 degrees F, spreading the chips or crackers in a single layer on a baking sheet, and bake for about 5 minutes. Allow cooling, then seal in a plastic bag or container.

When a casserole calls for a bread crumb topping, try using cheese-flavored or other flavored crackers instead. Crush them up, top your casserole with them, and drizzle on some butter or margarine and bake. My family enjoys this better than plain bread crumbs.
It is also a great way to use up crackers that have gotten a little stale. They become crispy when you bake your casserole. Flavored crackers are also good to crush up and use as an instant homemade shake and bake. With the many different flavors of crackers on the market today, it gives you a variety of flavors for coating chicken and pork chops.

When your cheese puffs go stale, just spread them on a cookie sheet and bake on about 350 degrees F. for a minute or two, it doesn't take long and they are fresh and crispy again!

Refresh stale potato chips, crackers or other snacks of such type by putting a plateful in the microwave oven for about 30-45 seconds. Let stand for 1 minute to crisp. Cereals can also be crisped.
I just crisped a 1/3 bag of Tortilla Chip "scoops" in the oven at 250 degrees F for 14 minutes. In single layer on a cookie sheet. Perfect! They were over a year old. (03/01/2006)
