How to Keep Lettuce Fresh

Two Methods:

Lettuce has a shorter shelf life than most vegetables, especially the tender butter lettuce variety. It stays in best condition in a humid, cold environment with minimal air circulation. (It's almost as though the crisper drawer was made for the purpose.) Learn a few tricks to keeping your lettuce good for the rest of the week, or even longer.


Easy Lettuce Storage

  1. Remove the core from crisp lettuce heads.Iceberg, romaine, and other lettuce with a stiff core last longer when this core is removed.Cut out the core with a knife, or pound the stem against a cutting board firmly, then twist the stem to remove the core by hand.
    • Do not remove the stem from butter lettuce, or any lettuce with loose, tender leaves.
  2. Wrap the lettuce in paper towels.Sandwich the head of lettuce — or loose leaves in single layers — between two soft, absorbent paper towels. These will absorb excess water but keep the lettuce in the moist conditions it prefers.
    • If the lettuce feels dry, dampen the paper towels.
    • If the lettuce is wet enough to soak the towels, squeeze them out and wrap the lettuce again in the same, moist paper towels.
    • If the lettuce is a bag of loose leaves, spin them dry in a salad spinner.
  3. Store in a plastic container.This can be a zip-locked bag, hard plastic container, or even a salad spinner. If using a bag, press out some of the air before sealing, without bruising the leaves. If using a hard container, fill it at least halfway with leaves.The more air in the container, the faster you'll get brown edges.
    • If you press out all the air and seal the container completely, the lettuce may develop off flavors due to poor respiration.Leaving a little air or cracking the container slightly may be a better idea, especially with leaf lettuce or a fridge that's on the warm side.
  4. Place in the crisper drawer.This is the coldest part of your fridge, which is ideal for leafy greens. Most grocery store lettuce should last 3-7 days here, depending on freshness, while iceberg may last up to two weeks.Fresh lettuce from your garden or a farm stand may last longer.
    • Do not squeeze the leaves into tight spaces with other foods, which may cause bruising.
    • Do not store in the same drawer as apples, pears, or tomatoes, which release high amounts of ethylene gas that can cause spoilage.
  5. Watch the container.If water is running down the sides of the container, lower your fridge's humidity settings or open the crisper drawer's air vents wider. (You may also want to drain out the excess water.) If you see ice in the crisper drawer or on the leaves, raise your fridge's temperature.

Extending the Lettuce's Shelf Life

  1. Exhale into your own personal cut lettuce supply.Carbon dioxide can reduce browning and increase shelf life in cut lettuce. One easy way to add CO2is to exhale a small amount into the bag of lettuce, then seal it.For sanitary reasons, do this only with lettuce you plan to eat personally.
    • Carbon dioxide is not beneficial for intact lettuce heads.
  2. Add a stronger carbon dioxide source.This clever way to add carbon dioxide can increase your lettuce's lifespan by five extra days, in the best case scenario. Here's how to set it up:
    • Freeze 1 tsp (5mL) white vinegar in a spice jar or other small container.
    • Pour 1 tsp (5mL) baking soda onto the frozen vinegar.
    • Leave the lid off the jar, and cover with several layers of paper towel. Fasten with a rubber band.
    • Keep this jar upright in a sealed container of lettuce. The vinegar will slowly melt and react with the baking soda to create CO2.
  3. Vacuum seal crisp lettuce in a glass jar.If you have a vacuum-packing machine, you can use it on a jar of iceberg lettuce to keep it fresh for up to two weeks.Romaine lettuce typically lasts a week when vacuum sealed. This does not work well with butter lettuce and other tender leaves.
    • You can imitate a vacuum packing machine with a much cheaper (but less effective) hand pump. Punch a hole through the jar lid with a thumbtack, cover it with electrical tape, and pump air out through the tape.
    • This will not work with a plastic bag of lettuce, as the leaves will be crushed in the vacuum.

  • Question
    When you wrap the leave of lettuce in paper towel, do you put the paper towel in the bag as well or just use it to wring out excess water?

    Yes, put he paper towel in the bag as well. Definitely wring out the excess water, too, in order to prevent the lettuce from rotting.
  • Question
    I purchased a plastic bag that is supposed to keep lettuce and vegetables from going bad. Do I wash the lettuce and vegetables first before putting them in the bag?

    Any extra moisture will speed up the decaying process, so you should store them unwashed and then wash them as you use them. If you do want to wash them ahead of time, then ensure that they are completely dry before you put them into the plastic bag.
  • Question
    Do I wash lettuce before storing it?

    If you are going to use it right away, wash it. If you want to keep it for a day or two, do not wash it as the moisture would turn the lettuce brown. You can also try placing a paper towel in a plastic bag with the lettuce to help absorb any moisture.
  • Question
    Should I water living lettuce?

    Just wrap the roots with a damp paper towel, then put a plastic bag around the paper towel. Store the wrapped lettuce in the fridge. This process will add several days to the shelf life of the lettuce.
  • Question
    What if you only have one crisper drawer and you have apples and tomatoes in addition to lettuce?

    They should all be fine in the crisper drawer.

  • Lettuce wilts when it loses water. If your lettuce wilts, restore it by placing the leaves in a bowl of ice water for 30 minutes.
  • Washing "pre-washed" lettuce does not increase safety. In fact, you're more likely to introduce new contaminants from your kitchen than you are to make the letter cleaner.For the same reason, do not wash unwashed lettuce until you are about to use it, so any introduced bacteria do not have time to grow.


  • Be extra careful not to contaminate the lettuce when vacuum-sealing, as the pathogens that survive in a vacuum do not leave visible signs.

Quick Summary

To keep most varieties of lettuce fresh, cut out the core with a sharpknife before storing it. However, if you are using a variety of lettuce with loose, tender leaves, like butter lettuce, leave the stem in place. Wrap the head of lettuce or individual leaves in paper towels, then place the lettuce and paper towels in a plastic container or resealable bag and place the container in the crisper drawer or your fridge. Do not store lettuce with apples, pears, or tomatoes, which release a gas that can cause lettuce to spoil faster.
