Can You Freeze Lettuce (How Long Does It Last & How to Do It?)

Lettuce is a leafy vegetable from the Asteraceae family. It is usually grown for its leaves but is also occasionally grown for its seeds or stem. There are many different types of lettuce, the most popular being iceberg. Lettuce itself is the most popular leaf to use in a salad and is also popular in many other types of cuisine. 

However, like many vegetables, lettuce has a very short shelf life. This can mean anything from having slightly wilted and unpleasant lettuce for your salad lunches to having rotten lettuce you need to dispose of before the week is over with.

This leaves many people reluctant to spend their hard-earned money on any kind of lettuce. 

However, we may have a solution! Being able to freeze lettuce would solve a lot of leafy vegetable woes, and there may be a way to do just that. Read on to find out more! 

Can You Freeze Lettuce?

Yes, you can! Some types of lettuce will freeze better than others, though most will freeze well. However, freezing lettuce successfully requires good preparation.

Types Of Lettuce

There are many different types of lettuce. Here are some types that freeze particularly well (except for iceberg lettuce, they all have thick leaves). 

  • Iceberg 
  • Romain
  • Boston 
  • Cos 
  • Bibb

Shelf Life Of Lettuce 

Lettuce will have a much shorter shelf life when not frozen. Different types of lettuce have different shelf lives. Here are a few examples of the average shelf life of lettuce (with correct refrigeration.) 

  • Iceberg (1 to 3 weeks)
  • Romaine (10 days)
  • Boston (3-4 days)
  • Cos (4 days)
  • Bibb (3-4 days)

How To Freeze Lettuce

Firstly, different types of lettuce should be frozen in separate bags. If you mix the flavors, then you could give all of the lettuce an unpleasant taste once thawed. There are two different ways to freeze your lettuce. 

Freezing Whole Lettuce Leaves

We understand how tempting it is to just throw a whole head of lettuce in the freezer and forget about it. However, if you want to preserve the natural state of the lettuce then it’s best to follow these steps. 

  1. Remove damaged leaves and cut the stalk of the lettuce. 
  2. Rinse the remaining lettuce leaves in cold water
  3. Blot the leaves dry with a paper towel, but take care not to damage the leaves. 
  4. Let the leaves air dry on a towel by spreading them out. Leave them for a few minutes. This is to remove as much moisture as possible. 
  5. Place the lettuce leaves in freezer bags. 
  6. Gently press down on the bags so the air inside is released. 
  7. Place the bag in the freezer, on top of other frozen products that may be heavier. 

Freezing Pureed Lettuce

Pureed lettuce is a less traditional way of preparing the leafy vegetable. Nevertheless, it can be used as part of some real tasty recipes, like stews, curries, or smoothies!

Here’s how to freeze it: 

  1. As before, remove the lettuce stalk. 
  2. Separate the leaves and then wash them in cold water. 
  3. Put the leaves in the blender with some water and blend until they form a puree. 
  4. Put the puree in ice trays and place them in the freezer. 
  5. Once these lettuce puree cubes are frozen, pour them into freezer bags. 
  6. Press gently on the bags to remove the air. 
  7. Place the bags in the freezer. 

How Long Will Lettuce Last In The Freezer?

Lettuce will last for around 6 months in the freezer, provided you follow the aforementioned storage tips. Frozen, pureed lettuce tends to last longer than frozen lettuce leaves because its fibers have already been broken down. 

The Problem With Freezing Lettuce (And How To Fix It)

Unfortunately, freezing lettuce often means their leaves will lose their flavor and crispiness. The best way to prevent this is to freeze the lettuce as soon as you bring it home.  

However, frozen lettuce will always be more watered-down in flavor and less crisp than fresh lettuce, but that doesn’t mean it can’t taste good!

How To Thaw Lettuce Leaves

It is important to thaw frozen lettuce leaves correctly, and there are two ways of doing this. The first is to place them on the counter to thaw at room temperature, a few hours before you want to use them. The second is to place the bag in the freezer and thaw overnight. 

How To Tell If Your Frozen Lettuce Has Gone Bad 

Unfortunately, lettuce is known to carry microbes, namely E. coli, and freezing the leaves does not kill them. This means that despite freezing, sometimes your lettuce will go bad. 

Normally, you will have to wait until your lettuce has thawed to determine its condition. Here are some clear signs that your lettuce needs to be disposed of and not eaten:

  • Soggy texture 
  • Wilting 

And most importantly: 

  • Discoloration 
  • A rotten smell

If you’re not sure whether your lettuce has gone bad or not, it is best to assume it has and dispose of it safely. 

What To Do With Your Frozen Lettuce

Fresh lettuce works best for a salad, but there are plenty of meals you can make that include frozen lettuce! From soups to smoothies, casseroles to stews to stir-fries, frozen lettuce can be a powerful asset to your kitchen.

Final Thoughts 

To freeze lettuce successfully, you should try and do it as soon as you get home from the grocery store. You must carefully follow the steps outlined in the article, carefully ensuring there is no air left in the bags before freezing. This way, the lettuce can remain fresh for up to 6 months! This is great news for lettuce lovers, as it means their favorite leafy vegetable can last a lot longer and they can continue to use it in a variety of meals. 

However, frozen lettuce is still susceptible to rotting, and you must check that it is safe to eat before cooking. If not, dispose of it safely. 

Whether you choose to freeze pureed lettuce or lettuce leaves, by following the steps we can almost guarantee your lettuce will be fresh and tasty.
