Things You'll Need
When cut and stored improperly, lettuce can brown and wilt very quickly. Brown lettuce is not only unappealing to look at, but also unpleasant to eat. There are several important tips you can follow when cutting and storing your romaine lettuce to keep it fresh. Following these tips will allow you to eat off of the same head of romaine lettuce for a week rather than having to make a trip to the store every time you want a salad.

Remove any bad or wilting leaves from the head of romaine lettuce.
Rinse the head of romaine lettuce to remove dirt from it.
Rip the lettuce rather than cutting it. Ripping the romaine leaves will often damage and bruise the lettuce less than cutting it with a knife. Rip the lettuce into large chunks if you wish to store it for a longer period of time. This will cause less damage to the lettuce, preventing it from browning as quickly.
Shake the lettuce to remove excess water, then pat the lettuce down with paper towel to thoroughly dry the lettuce.
Place the lettuce in a salad spinner to remove as much moisture as possible. It is extremely important to remove as much moisture as you can; this will keep the lettuce from turning brown after it has been cut.
Put the romaine leaves in a large bowl.
Place a single paper towel on top of the romaine leaves to help absorb some of the moisture that builds up while the lettuce is being stored.
Cover the top of the bowl with plastic wrap.
Remove the paper towel and replace it with a new one every few days to control the moisture level.
