Cilantro can look crisp at the grocery store and turn limp or start rotting before you get through the bunch. That short window becomes a problem when you buy it for several meals spread across the week.
A home cook on Reddit had that exact problem: cilantro bought on Saturday was wilted or beginning to rot by Thursday. The answers kept returning to a simple change in storage. Instead of leaving the bunch in its produce bag, several cooks stand cilantro upright in water, much like a bouquet of flowers.
The jar is only part of the trick. Several commenters cover the leaves with a loose plastic bag and keep the whole setup in the refrigerator, creating a protected space around the cilantro while the stems sit in water.
Cilantro Stems Go Into Water Like Cut Flowers
Remove any damaged or deteriorating leaves first, then trim the ends of the stems. Place the bunch stem-side down in a sturdy glass or jar with water at the bottom.
One Reddit cook uses a quart Mason jar and changes the water each day, reporting that cilantro stays usable for more than a week. Another commenter who identifies as a chef fills a wide glass about one-third with water and says the method can preserve cilantro for a few weeks.
A wider container can also help keep the tall bunch from tipping over on a refrigerator shelf.
Plastic Bag Over the Leaves Completes the Setup
Leaving the cilantro uncovered isn't the only option. Several cooks add a clear produce bag or large zip-top bag over the foliage before putting the jar in the refrigerator.
One commenter describes tucking a produce bag around the jar to create a humid dome. The chef uses a gallon-size zip-top bag tented over the bunch rather than packed tight against the leaves.
The result looks less like conventional food storage and more like flowers under a small cover: stems in water below, leaves protected above.
Water Still Needs to Be Changed
Putting cilantro into a jar isn't a set-it-and-forget-it method. The water needs attention while the herbs sit in the refrigerator.
Recommendations in the discussion range from changing it every day to every other day. The chef who reports keeping cilantro for up to a few weeks changes the water every other day.
Check the bunch at the same time and remove any leaves or stems that have started to deteriorate rather than leaving them mixed with the rest.
Paper Towels Offer an Option When a Jar Won't Fit
A tall jar and bag take up refrigerator space, and several Reddit cooks use another method when upright storage isn't practical.
Their approach is to remove damaged pieces, wash the cilantro, dry off excess water, and store it with paper towels inside a container or bag. Some commenters report getting well over a week from cilantro stored this way.
The two methods look different, but neither involves leaving the bunch untouched in the thin produce bag it came home in. For anyone accustomed to finding wilted cilantro several days after shopping, a glass of water and a loose bag over the top may be worth the refrigerator space.
