Expiration & Storage Tips
When does butter lettuce expire?
An unopened package of butter lettuce can stay fresh for about 5 to 7 days past the package's printed date. Once opened, the leaves should be eaten within 3 to 5 days. These times are only applicable if the lettuce is refrigerated. In terms of freezing, butter lettuce does not freeze well and will become slimy and unpalatable upon thawing.
How do you tell if butter lettuce is bad?
Butter lettuce has gone bad if it has a slimy or moldy texture, appears wilted, and the edges of the leaves are discolored, usually going from a vibrant green to a darker brown. If the lettuce gives off an off or sour smell, it's definitely time to toss it.
Tips for storing butter lettuce to extend shelf life
• Keep the lettuce in a crisp drawer in your fridge, where temperatures are slightly higher than the rest of the fridge.
• Do not wash the lettuce until you're ready to use it. Washing prior to storage can lead to faster spoilage due to excess moisture.
• Store the lettuce in a loose, plastic bag with a sheet of paper towel to absorb any excess moisture.
• Avoid storing near fruits that release ethylene gas, like apples and bananas, which can cause the lettuce to decay faster.
