How to Store Lettuce in the Refrigerator

Learning how to store lettuce in the refrigerator is mostly about moisture and placement. Lettuce wilts when it loses water and spoils when it stays wet, so the steps below focus on keeping the leaves dry and cool. The extension guides reviewed here agree on the basic method but differ on whether to wash lettuce before it goes into storage, and that difference is covered in its own section.
Quick answer
- Wrap dry lettuce in a dry lint-free towel, place it in a plastic bag, and store it in the refrigerator, as Purdue Extension advises.
- Illinois Extension says to wash the lettuce, drip dry it, and place it in a plastic bag in the refrigerator.
- Store lettuce in the crisper drawer, and keep it away from the back wall of the refrigerator.
- Purdue Extension gives about 5 days of refrigerator life for lettuce stored this way.
Drying step: dry first or wash first
Purdue Extension’s method starts with dry leaves: “Wrap dry lettuce in a dry lint-free towel, place in a plastic bag, and store in the refrigerator.” The advice is to dry the lettuce thoroughly before wrapping it, which keeps surface water away from the leaves in storage.
Illinois Extension gives a different order: “To store lettuce, wash, drip dry and place in a plastic bag in the refrigerator.” In this method, the leaves are washed first and then allowed to drain before bagging. Both sources end with a plastic bag in the refrigerator, but the moisture step is different.
The difference is practical. A cook who washes the lettuce should drain it well before bagging, since Illinois names draining as the step before storage. A cook who prefers to wash the lettuce just before eating can follow the Purdue order and store the leaves dry. The sources reviewed do not say which order gives a longer storage life, so the choice is about the cook’s routine rather than a sourced shelf-life difference.
Where to put lettuce in the refrigerator
Arizona Extension gives a clear location rule: “Store lettuce in the crisper drawer of your refrigerator.” Arizona Extension names the crisper drawer as the place to store it.
Illinois Extension adds a temperature point: “The coolest part of most refrigerators is usually on the first shelf against the rear wall.” That line seems to point toward the back of the refrigerator, but Arizona Extension gives the opposite warning: “Keep lettuce away from the back of the fridge, where it might freeze.” The two sources both use the rear of the refrigerator as the reference, so the practical rule is to avoid the very back wall, where the cold can be strong enough to freeze leaves, and to store the lettuce in the crisper drawer as Arizona recommends.
The sources reviewed do not give a temperature for lettuce. The refrigerator’s own temperature setting and the crisper drawer are the practical controls available to a home cook.
Harvest timing and unwashed leaves
Illinois Extension adds two points. When seedstalks begin to form, it advises that the lettuce be harvested immediately and stored in the refrigerator. For leaves that have not been washed, it says to “Wrap fresh, unwashed leaves in plastic wrap and store in the refrigerator for a few days if necessary.” The phrase “for a few days” is the only storage period Illinois gives in the text reviewed, so a cook who needs a longer period should follow the Purdue method and check the leaves each day.
Lettuce should be checked before each use. Remove any leaves that look damaged before wrapping the rest, so that damaged leaves do not sit against good ones. This is a planning step rather than a sourced rule, and the sources reviewed do not give a time after which a damaged leaf should be discarded.
Lettuce that does not store well
Storage works best with fresh, undamaged leaves. The Arizona source says lettuce “does not freeze or dry well, and you cannot can it.” That line matters for storage planning, because it means the refrigerator is the main home method for keeping lettuce fresh for a short period, while freezing, drying, and canning are not recommended in the sources reviewed.

How we chose these sources
The reviewed material was limited to extension publications. Purdue Extension, Illinois Extension, and Arizona Extension were each opened on 2026-10-27, and quotes were checked against the fetched text. Statements that appeared only in search summaries, and were not confirmed in the fetched pages, were left out. Purdue Extension was used for the dry-first method and the approximate shelf life. Illinois Extension was used for the wash-first method and fridge placement. Arizona Extension was used for the crisper drawer, the back-wall warning, and the note that lettuce does not freeze or dry well.
What we could not verify
Several parts of a lettuce storage routine could not be confirmed from the sources opened for this article. The gaps below are the main limits on what a cook can rely on from these three pages alone, so a fuller guide should be checked before a storage time is relied on.
What the sources do not say
- Which washing order gives a longer storage life, since Purdue and Illinois use different steps.
- The exact refrigerator temperature for lettuce.
- A shelf life for every lettuce type, since Purdue gives about 5 days and the other pages do not give a number in the text reviewed.
- Whether the Illinois unwashed-wrap method keeps lettuce longer than the Purdue method.
- How to judge from appearance alone when lettuce is no longer fit to eat.
Frequently asked questions
Should lettuce be washed before it is stored?
The sources differ. Purdue Extension says to wrap dry lettuce, while Illinois Extension says to wash the lettuce, drip dry it, and bag it. Either way, the leaves should be dry enough that surface water does not sit on them in the bag.
Where in the refrigerator should lettuce go?
Arizona Extension recommends the crisper drawer. It also warns to keep lettuce away from the back of the refrigerator, where it might freeze.
How long does lettuce keep in the refrigerator?
Purdue Extension gives about 5 days for lettuce stored with its method. The Illinois and Arizona pages do not give a specific day count in the text reviewed, so check leaves for damage each day.
Can lettuce be frozen or dried to store it longer?
The Arizona source says lettuce “does not freeze or dry well, and you cannot can it.” The sources reviewed do not describe a tested freezing or drying method for lettuce. See how to preserve tomatoes for a different preservation topic with its own guidance.
How long can unwashed lettuce be wrapped?
Illinois Extension says to wrap fresh, unwashed leaves in plastic wrap and refrigerate them “for a few days if necessary.” Purdue Extension’s dry-leaf method gives about 5 days. Neither source gives a longer period, so a cook who needs more time should use fresh leaves in a shorter window.
