How long can lettuce sit out?

Lettuce lasts for about 2 hours when left out at room temperature. 

You should discard the lettuce that has been left in open for more than 2 hours as bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore there are greater chances of the lettuce being already contaminated with bacteria when left out for more than 2 hours.

Moreover, if the temperature of the surroundings is about 90 degrees Fahrenheit, then the process of spoilage takes place at a faster pace and it is recommended to discard lettuce that is left out in the open for more than an hour at 90 degrees Fahrenheit.

Shelf life of lettuce in the fridge

Lettuce lasts for about a week in the fridge if it is properly stored at or below 40 degrees Fahrenheit. But it is recommended to use the lettuce within 3-5 days to enjoy its peak quality and freshness. Afterward, the lettuce often starts to lose its color and crispiness.

It is worth mentioning that the figures mentioned above are the estimated shelf life of the lettuce.

Can you freeze lettuce?

Lettuce can lose its crunch, once the frozen lettuce gets thawed. Thus, not only the texture of the lettuce having high moisture content will suffer but their taste profile won’t also be the same. Therefore it is not recommended to freeze lettuce.

Tips to properly store lettuce

  1. In the case of the lettuce head, you should wash it carefully and after drying it with the help of a paper towel, wrap the whole lettuce head in damp paper towels and plastic wrap. You can even store the lettuce head wrapped in damp paper towels in a plastic zipper bag.
  1. In the case of the fresh lettuce leaves, it is recommended to wash them first and dry them with the help of a paper towel or you can even dry them in the salad spinner. Afterward, take a bowl, put all the lettuce leaves in it, now take a damp cloth or paper towel and place it on the lettuce leaves. Lastly, wrap the bowl with the help of cling film or plastic wrap. With the help of a needle or pinhole make some holes in the plastic wrap as the lettuce needs a bit of airflow to remain fresh.
  1. Always be sure to refrigerate lettuce at or below 40 degrees Fahrenheit.
  1. When it comes to green vegetables or lettuce, it is better to store them in a bowl and cover them with a damp cloth or paper towel. Afterward, seal it with the help of plastic wrap or cling film.
  1. In the case of lettuce salad, it is recommended to mix the vinaigrette or any other dressing of your choice in the lettuce when you are ready to serve it. If you want to store the lettuce salad then you should store lettuce and vinaigrette separately.

Ways to spot bad lettuce

There are a couple of indicators that point out bad lettuce. You can tell if your lettuce has gone bad by considering its appearance, texture, and smell.

Appearance

The discoloration in the lettuce (brown color) is an indication that your lettuce is past its prime age.

Texture 

If you notice that the lettuce has softened or has a slimy texture, then it is an indication that it has gone bad. Moreover, in the case of lettuce salad with dressing, if it becomes soggy, then it indicates a bad lettuce salad.

Smell

If you notice some off-smell (rotten or sour smell) or something that does not quite smell like the fresh lettuce itself then it means that your lettuce has gone bad and you should discard it.

Thus, if you find that the lettuce has off-colors, off-smell, or off-taste, then it is better to discard it.
