Does Lettuce Really Need To Be Refrigerated?

The problem with a whole head of lettuce is that it takes up a lot of room — does this leafy, green salad vegetable really need to be kept in the refrigerator?

Most of us keep lettuce in the fridge without even questioning it, but you may have seen lettuce on display at the store that is not kept chilled — this might lead you to start thinking that lettuce can be stored at room temperature.

As with many things, there is no clear-cut answer to whether lettuce needs to be refrigerated! It is not always essential to store lettuce in the fridge, but this depends on the type and cut, as well as how quickly you are going to use it.

Lettuce that is left at room temperature for a few hours or more will still be perfectly fine to eat, but it will not stay fresh for as long as when it is kept in the chiller.

It is also more prone to bacterial contamination, so should be carefully washed before it is consumed.

On the flip side, keeping lettuce refrigerated can also be detrimental to the freshness of the leaves if you get it wrong!

So, to help you out, we’ve created the ultimate guide to storing lettuce in all its different forms, both in and out of the refrigerator.

Does A Head Of Lettuce Need To Be Refrigerated?

Buying a whole head of lettuce is the best way to ensure you get fresh salad leaves for the maximum length of time. As soon as the leaves are cut or removed from the stem, they start to deteriorate.

But how do you store a head of lettuce to keep it at its best?

The key to keeping lettuce crisp and fresh is to provide the perfect levels of moisture and air. Too much or too little of either, and it will either turn floppy and limp or start to become slimy and rotten.

When storing lettuce, the crisper drawer of your fridge is your best friend! While we tend to put vegetables in here without really thinking about it, the crisper is designed to do just that — keep your salad crisp and fresh.

Leave the head of lettuce whole and unwashed, and wrap a damp paper towel around the stem. Pop it into the crisper drawer, and it will be in the perfect place to keep the leaves crisp for several weeks.

If your head of lettuce comes in a plastic bag, remove it from the bag to keep it in peak condition. Sealing whole lettuce inside a bag will restrict airflow and cause it to deteriorate more quickly.

It is not essential to store a whole head of lettuce in the refrigerator if you are going to use it within a day or two. Make sure the base is well wrapped in a damp paper towel, and keep the entire head of lettuce in a cool, dark place.

Does Chopped Lettuce Need To Be Refrigerated?

Once lettuce has been cut or chopped, it will start to deteriorate at a faster rate than a whole head of lettuce. Chopped lettuce should be stored in the refrigerator to keep it as crisp and fresh as possible.

Make sure the chopped lettuce has been washed, and remove any parts that have signs of damage such as browning or slimy edges.

Next, remove excess water without damaging the lettuce — a salad spinner is ideal for this, or you can gently pat it with a kitchen towel.

Place a dry paper towel in a zip-lock plastic bag or airtight storage container, then add the chopped lettuce leaves. The paper towel will absorb excess moisture and slowly release it, helping the lettuce stay fresh for as long as possible.

Check the lettuce daily and removed any damaged or slimy parts. If the paper towel is very damp, replace it with a dry one to prevent excess moisture from building up.

It is not advisable to store chopped lettuce anywhere other than in the refrigerator, as the sliced edges are highly prone to bacterial contamination.

Only ever eat chopped lettuce that looks and smells crisp and fresh — if in doubt, throw it out!

Do Salad Leaves Need To Be Refrigerated?

Prepacked bags of salad leaves are beautifully crisp and fresh when you first open them, then they quickly start to deteriorate. This can be very frustrating, but some simple steps will help to keep them fresh for longer!

These bags of salad leaves will often state that they are packed in a protective atmosphere to help them stay fresh in the chiller cabinet.

When we open the bag, we expose the contents to air, moisture, and bacteria, all of which can accelerate the decomposition process. It is a good idea to treat them in just the same way as chopped lettuce.

Wash and gently dry the leaves, then place them into a sealable container with a dry paper towel. Remove any leaves that look past their best on a daily basis, and you’ll keep the remainder in peak condition for much longer.

How Long Does Lettuce Last In The Fridge?

The length of time that lettuce lasts in the fridge will depend on the type of lettuce and how it has been prepared.

If stored correctly, a head of lettuce can last for up to three weeks in the refrigerator. This depends on it being chilled as quickly as possible after harvesting.

You will also need to check it regularly and remove any outer leaves that are starting to brown and wilt.

Loose or chopped lettuce leaves do not last as long and should be used within 7-10 days.

Pre-packed bagged salad leaves will be marked with a best-before date, and will normally last unopened for around five days. Once opened, they start to deteriorate quickly and should be consumed within 1-2 days.

You can prolong this time by washing the leaves and storing them in a plastic container with a dry paper towel.

How To Store Lettuce In The Refrigerator

The best place to store lettuce in the fridge is in the crisper drawer. This provides the perfect airflow and moisture levels to keep lettuce crisp and fresh.

If you have a whole head of lettuce, a damp paper towel around the base can help to prevent wilt. It can be placed in the crisper drawer, either as it is or loosely wrapped in a plastic bag.

Never seal a whole head of lettuce in a plastic bag, as it will deteriorate very quickly due to the build-up of moisture.

Chopped or loose lettuce leaves will need a bit more care and attention to keep them fresh. They should be washed and gently dried, then placed in a sealable bag or container with a dry paper towel.

You will then need to check your lettuce every day and remove any wilted, brown, or slimy parts. If the paper towel is dry, add a few drops of water to freshen up the lettuce.

How To Store Lettuce Without A Refrigerator

The key to keeping lettuce fresh for longer without a refrigerator is to avoid any damage to the leaves. A whole, unwashed lettuce has the best chance of staying fresh for up to a week if stored correctly in a cool, dark place.

Wrap the base of the lettuce in a damp paper towel and place it in a large plastic bag. Leave the top of the bag open to allow air to circulate freely.

Place the bag in the coolest, darkest place you can find in the house, and check it daily for deterioration.

When the time comes to eat your lettuce, remove any leaves that are slimy or brown. Wilted leaves can be revived by placing them in an ice bath for a couple of minutes.

One clever hack to keep lettuce fresh without the need for a fridge is to pick it fresh from a windowsill salad tray!

You can either grow your own or buy them from the store. They are often labeled as “cut and come again” salad trays and will give you fresh leaves for several weeks without the need for a refrigerator.

And if you really get the bug for growing lettuce, there is nothing fresher than a head of lettuce harvested directly from your own garden, balcony, or windowbox!
