Freeze broth in sections
Broth should be tossed within a week of opening the container, but that usually means wasting about half the carton. Stowing the whole container commits you to thawing the rest when you need it, but freezing the broth in an ice cube tray makes it easy to take out just what you need, according to The Kitchn. As a bonus, the small cubes thaw faster than a large block of broth would. (Make sure you never, ever eat these foods past their expiration date.)
