Can You Freeze Lettuce?

Perhaps you have a garden full of lettuce that you can’t possibly eat before it goes bad. Or maybe you’ve encountered a great sale on lettuce at your local supermarket. Either way, you’re likely wondering—can you freeze lettuce?

You may think that freezing lettuce is impossible because of its fragility and high water content. However, like lettuce, most vegetables have over a 90% water content which helps lettuce maintain rigid cell walls when frozen. The downside to all that water content is that if you don’t freeze lettuce properly, those cells break down upon thawing. Improperly frozen and thawed lettuce also has a watered-down flavor and texture.

In this article, we’ll show you the ins and outs of freezing lettuce to maximize its shelf life and maintain its quality as best as possible.

Can You Freeze Lettuce?

Yes you can freeze lettuce, although it requires thoughtful preparation. It also depends on the species of lettuce you plan on freezing. For example, heirloom lettuce tends to withstand freezing better than other lettuce varieties, such as iceberg.


Examples of lettuce that freezes well include:

  • Romain
  • Cos
  • Boston
  • Bib

The common theme that all of these lettuce varieties have is thicker leaves. Using iceberg lettuce as a comparison, a quick trip to the salad aisle at your supermarket will give you a good visual for the types of lettuces that are better for freezing.

How to Freeze Lettuce

Despite the difficulties that come with freezing lettuce, here’s some good news—there are two ways you can freeze it. Most people want to freeze whole lettuce leaves. However, you also have the option to puree your lettuce, which has its advantages—we’ll cover those shortly.

When freezing lettuce, it’s best to freeze different lettuce varieties in separate bags. Otherwise, the mixing and matching of flavors could lead to an unpleasant taste once you thaw them.

Got your lettuce on hand? If so, read below for whole and pureed lettuce freezing methods in this step-by-step guide.

Freezing Whole Lettuce Leaves

It may be tempting to toss a head of lettuce in your freezer, but to preserve your lettuce’s natural state as best as possible, you’ll need to perform the following steps.

Step 1: Cut out the stalk and any damaged leaves.

Step 2: Rinse the leaves in cold water.

Step 3: Dry the leaves the best you can with a colander and blot them dry with a cloth or paper towel. Take care not to rub them too vigorously. Otherwise, you could damage the leaves.

Step 3: Spread the leaves out on a towel and let them air dry for a few minutes. The goal is to remove as much moisture as possible before freezing them, but you don’t want your lettuce leaves to get warm in the process.

Step 4: Carefully place your lettuce leaves in freezer bags and press down on them to release air.

Step 5: Set the freezer bag in your freezer on top of any heavier items.

A fun freezer trick we love is placing a straw inside the freezer bag and sucking out excess air. By removing as much air as possible, you’ll maximize the lettuce’s freshness the next time you go to eat it.

Knowing how to thaw frozen lettuce leaves is equally as important as learning how to freeze them. When you’re ready to whip up a lettuce meal, pull the freezer bag out of your freezer and set it in your fridge overnight. Alternatively, you can place them on your counter for a couple of hours so the lettuce can thaw at room temperature.

Freezing Pureed Lettuce

If you can’t picture whipping up a salad with frozen lettuce leaves, you’ll likely appreciate this puree option. Although pureed lettuce is less traditional, there are some great recipes you can make with it, which we’ll cover shortly.

Below are the steps you’ll need to take to puree and freeze lettuce.

Step 1: Remove the stalks from the lettuce, separate the leaves, and wash them well with cold water.

Step 2: Toss the leaves in a blender and add a bit of water.

Step 3: Place the puree in ice trays and pop the trays in your freezer.

Step 4: Once your lettuce cubes freeze, pour them into a freezer bag, remove all air from the bag, and store them in your freezer.

The benefit of pureeing your lettuce instead of freezing the leaves is that you don’t have to worry about a wilted or slimy texture that can sometimes happen after freezing whole lettuce. Frozen pureed lettuce is ideal for making smoothies, curries, and stews.

Unlike frozen lettuce leaves, it’s best not to thaw your frozen lettuce puree unless a recipe specifically calls for it. There’s no need to create an unnecessary mess!

How Long Will Lettuce Last in the Fridge/Freezer?

The next time your next-door neighbor asks you, “Can you freeze lettuce?” you’ll know how to answer them. But their next question will likely look like this—for how long can you freeze lettuce?

Lettuce lasts around six months in the freezer if properly stored. As a general rule, pureed lettuce lasts longer than lettuce leaves since you’ve already broken down their fibers, and it’s okay for them to have water.

Freeze lettuce

Since one of the issues people face when freezing lettuce is the leaves losing their crispness and flavor, you should aim to freeze your lettuce shortly after bringing it home.

When it comes to storing lettuce in the fridge, you can expect it to last around ten days, assuming the lettuce is fresh, and you place it in an air-tight container with paper towels.

How to Tell if Your Frozen Lettuce is Bad

Now that you know how to freeze lettuce, it’s important to know what to look for once you pull it out of your freezer and thaw it. After all, lettuce can carry microbes like E. coli, and freezing the leaves, unfortunately, doesn’t kill them.

Most likely, you’ll need to wait until your lettuce thaws to assess its condition. Below are some tell-tale signs that your lettuce should make its way into the trash can instead of your stomach.

  • Rotten smell
  • Discoloration
  • Extreme wilting
  • Soggy texture

Since vegetables don’t come with expiration dates, using your senses is the best way to determine if your frozen lettuce went bad. Pureed lettuce is a little more difficult to tell since the leaves are already in a mushy blend.

When it comes down to it, if you’re unsure whether your frozen lettuce is bad, it’s best to avoid the possibility of a stomach ache and toss your lettuce in the trash.

What to Do With Frozen Lettuce

Newbies to the frozen lettuce world typically decide to freeze their lettuce because they have too much of it and don’t want it to go to waste. So, once you’ve spent time carefully preparing your lettuce and making sure your ice cream tubs and Thanksgiving Day turkey aren’t crushing them, you might be thinking, now what?

Below are some of the most popular ways to use frozen lettuce:

  • Soups
  • Stir-fries
  • Curries
  • Smoothies
  • Stews
  • Casseroles

You’ll notice that we didn’t mention making a salad with frozen lettuce. Can lettuce be frozen and repurposed into a salad? Technically, yes.

However, if you feel the need to eat your frozen and thawed lettuce like fresh lettuce, we recommend eating the leaves in a wrap. The reason being is that regardless of how careful you are with preparing to freeze your lettuce, it’s going to have less crisp and a more watered-down flavor than before you froze it.

When using your frozen lettuce in curry, soup, stew, and stir fry recipes, add the lettuce leaves when your recipe calls for other leafy greens. For casseroles, mix the leaves right in with the rest of the ingredients. Frozen lettuce puree is an excellent option for smoothies. In that case, you can use them as you would ice cubes, giving you an added nutritional boost compared to pure water.

Frozen Lettuce Soup

If you’ve never tried lettuce soup, using your frozen lettuce is an excellent opportunity to try out this tasty dish. Making this soup is easy; heat 1 cup of chopped onions, 1 garlic clove, and 3 tablespoons of butter in a pot.

Add in spices to taste—suggestions include coriander, salt, and pepper. Then, pour in three cups of water, some chopped potato, and eight cups of frozen and thawed lettuce leaves, or the equivalent in frozen lettuce puree.

Wait until the potato cooks through, and voila, you have yourself a delicious pot of lettuce soup!


So, can you freeze lettuce? We hope by now you know that you can. Although frozen lettuce is incomparable to fresh lettuce in terms of its crispness and flavor, freezing lettuce leaves is an excellent option if you don’t want your lettuce to go to waste. Freezing food also preserves vitamins and minerals, so even if your frozen lettuce loses its fresh look, it still offers excellent health benefits.

  1. I am not very sure about lettuce or cucumber as they are only 2 of us I seem to throw out an awful lot of salad

    1. Yes, we definitely can get busy sometimes and it’s hard to eat everything we have on-hand. Especially if you have something to do with frozen vegetables, like putting into a recipe, it can be worthwhile.

    2. I have not tried freezing lettuce, but cucumbers can be saved for a few weeks by putting them in a jar of salted water in the fridge to which some vinegar has been added 1/2 cup vinegar, 1 cup water and one tablespoon of salt. Leave cucumber whole or sliced. Rinse before adding to salad if desired. Another method I use for really small amounts of cucumber is just adding them to an existing jar of pickles that has already been opened. Store in the fridge of course.
