Do croissants have to be refrigerated?

Croissants do not need to be refrigerated; in fact, storing them in the refrigerator can make them stale more quickly. The best way to keep croissants fresh is to store them in an airtight container or a paper bag at room temperature for up to two days. If you need to keep them longer, freezing is a better option. When ready to eat, you can reheat them in the oven to restore their flaky texture.
