Expiration & Storage Tips
When does asparagus expire?
Unopened, asparagus can last about 1-2 weeks in the refrigerator if stored properly. However, it's best to consume it within the first week for optimal freshness and flavor. Once opened or cut, the lifespan decreases to about 2-3 days in the refrigerator. If you have blanched and frozen your asparagus properly, it's generally good for up to 8-12 months in the freezer, though again, using it earlier will maintain better quality.
How do you tell if asparagus is bad?
You will know asparagus have gone bad when they become soft and limp, and the vibrant green color turns to a dull green. They may also emit a strong unpleasant smell. Mold growth is a sure sign that your asparagus has spoiled. If only a part of the bunch has gone bad, saving the rest is possible by immediately removing the spoiled parts.
Tips for storing asparagus to extend shelf life
• Keep the asparagus upright in your refrigerator. Store them in a large cup with an inch of water at the bottom, just like you would store fresh flowers! This can extend their freshness by several days.
• If it's not possible to store asparagus in a cup of water, you can also wrap the bottom of the stalks in a damp paper towel, and then cover the whole bunch in a plastic bag before placing in your refrigerator crisper drawer.
• It is best to store asparagus away from fruits like apples and bananas, as these produce ethylene gas that could hasten the aging process of the asparagus.
• To freeze asparagus, wash and dry the stalks, snip off the tough ends, and blanch by boiling for 2 minutes and then immediately plunging into cold water. Dry again, and freeze in a single layer before transferring to a sealable freezer bag. This will allow you to enjoy asparagus all year round.
• Always remember to practice FIFO (First In, First Out). Use the older asparagus first as you acquire new ones.
