Can You Freeze Lettuce? (Explained)

Freezing lettuce is a common practice. However, it does come with its own baggage.

Lettuce has become an integral part of our diet. At times, we end up buying more than we need. And when the lettuce is being sold at half-price, who would avert their eyes from a 50% off tag? Thus, we wound up purchasing lettuce in bulk and then wonder what to do with the rest.

Freezing is an ideal option. It prevents the development of bacteria and enzymes and preserves the vegetable for a long time. But can you freeze fresh lettuce? Is it even safe to freeze the lettuce? Read on to have all your queries circling freezing lettuce cleared!

Can you freeze fresh lettuce? While freezing fresh lettuce is done in many households, scientifically, it should be avoided. The reason lies in how the chill of the freezer affects the biology of the lettuce. When the lettuce succumbs to low temperatures of the freezer, ice crystal begins to form on the plant’s cells and continues to expand as the vegetable continues to get frozen. This expansion of ice can damage the cell wall beyond repair. This would collapse the cell wall of the plant and expose its cell organelles. This slow process turns the fresh and fluffy lettuce into a bunch of wet pulp. 

While the water expansion does not happen in the case of peas or corn because of the little water content in it, lettuce is a different story altogether. Lettuce has exponentially high moisture content. On top of that, it also has already weak cell walls.

Freezing it would deteriorate the stand of the cell walls, and all you will end up with is ugly pulp. In such a predicament, you’re left with no option other than to bin the lettuce. Therefore, freezing lettuce is not easy. But the good news is, it is very much possible. There are plenty of things to do before you place the lettuce in your freezer, though.

How to Freeze Lettuce?

Lettuce can be frozen if you know the methodology of doing it. Although, the procedure of freezing the lettuce varies from type to type. There is no general rule of thumb that applies to freezing all the lettuces. Not only the type but the origin of the lettuce also has many roles to play in the freezing capabilities of the lettuce. The types of lettuces that can be frozen and the types that cannot be frozen are discussed in the coming sections.

The origin factor also contributes to the whole freezing thing. The lettuces that you grow at your own home or your farm are much more suitable for freezing. This is because you would have harvested the crop right after it was fully-grown. This lettuce is very much likely to have been processed immediately and sent straight into the walls of your kitchen.

But if it’s store-bought lettuce we’re speaking of, then the process of its entry into your kitchen is entirely different. Store-bought lettuce goes through the process of storage, warehousing, and transportation. It then spends much of its time sitting on the shelf of the store before you come and pick it up.

This entire journey of the store-bought lettuce ends up having an impact on the construction of the lettuce and even deteriorates it. Hence, putting store-bought lettuce in the freezer would require some foreplay. There’s much that needs to be done, and you simply cannot go wrong with the method; otherwise, you’d end up doing more harm to the lettuce than good.

You could freeze fresh lettuce in the following manner;

Step 1: Divide the bunch of lettuce and wash each leaf with precision. Ensure the dirt of the day has been removed entirely from the lettuce with a stream of fresh water. Clip out the bases of the leaves and wash them again.

Step 2: Dry the lettuce thoroughly. You need to remove all the water from its surface to increase the probability of optimum freezing. We do not want a collaborative effort of internal and external water content to turn the lettuce into pulp. Thus, use dry towels or whatever you generally use to dry your vegetables. You could also keep it under the sun for surety.

Step 3: Divide the lettuce bunch into several groups and place each group into separate sealable freezer bags. Once you place the lettuce inside, get all the oxygen inside the bag out, or as much as you can. For this, cup the bag inside your hands and squeeze it. Don’t squeeze too hard that you end up damaging the lettuce.

Just enough that you know that the air is out. Neatly seal each bag and place it all inside the freezer. Ensure that even after you place the lettuce in the freezer, there’s plenty of room left for other stuff you might want to keep there.

Once you’ve placed the lettuce in the freezer, use it within six months. You might even narrow this period down to 3, not knowing the age of the lettuce. Just don’t let it rot inside the freezer indefinitely because that is exactly what will happen if you’re negligent enough.

There is also an alternative way to freeze the lettuce, which will involve your ice trays.

Step 1: Empty your ice trays of all the cubes.

Step 2: Puree the lettuce by running it once in the mixer. Keep taking a spoonful of the puree and place it inside each block in the ice tray.

Step 3: Add some water in each block after the puree has been added. Place the tray inside the freezer and wait for them to get frozen.

Step 4: Once the cubes have been made solid, take all the lettuce cubes out and place them all inside the freezer bags. Put the bags inside the freezer and bring them out once you’re ready to make use of liquidized lettuce.

You can use the liquidized lettuce in preparing various things! Freezing the lettuce using this method will take a toll on its taste or texture.
