So, can you freeze leeks? Yes, it is possible to freeze leeks. Leeks can be stored by freezing them so that they’ll stay fresh and retain that great mild flavor. Moreover, they can be stored for almost 10 months with the proper freezing technique.
Now, if you want to know more about how to freeze leeks, we recommend reading further to learn more!
Is It Possible To Freeze Leeks?
As we mentioned above, yes, it is possible to freeze leeks.
You can keep leeks in a perfectly edible condition for 2-3 months. However, if you want to keep them well for a more extended period, the fresher you freeze them, the better!
Leeks may freeze whole, but we recommend avoiding this technique of freezing. It is because they will take a longer period to defrost. Additionally, you also won’t be able to use your leeks until they have thawed completely!
How To Freeze Leeks
First, there are a few things that you require to freeze leeks. These include:
- Knife and cutting board for trimming the root ends and excess stems of the leeks.
- A pot and a bowl for hot and cold water. They should be big enough to submerge the leeks in it.
- Thick towel (or any other piece of cloth) for absorbing the excess water.
- Freezer bag or airtight container for saving the leeks in the freezer and also save on some space.
- Marker pen for marking the bag in which you have kept the leeks. This will help in easy access from the refrigerator.
- Baking tray for spreading your leeks on during flash freezing the leeks.
- Greaseproof paper for placing on the baking tray. You need to place the leeks on this.
Once you have the above things, you can begin to clean the leeks.
The main challenge with cooking leeks is that they are often very dirty. When leeks grow, they get covered in soil and dirt to be protected from too much sunlight. This is also to ensure that they grow light in color and become tender.
However, this same process that ensures its tenderness results in sand and dirt lodged deep inside the leek!
There are basically two ways to clean leeks. The method you use depends entirely on the usage of the leeks. The two ways are as follows:
Cut the roots off the leeks and slice them lengthwise. Now, decide how much leeks you require and make crosswise cuts. Leave the last couple of inches which are dark green in color.
Then place the chopped leeks in a bowl of cold water. Use hands to agitate the leeks and remove the dirt clinging onto them.
This process is best used for leeks which you’re planning on later incorporating into a soup or stew!
Place the leeks on a chopping board. Now insert the tip of your knife about ⅕ inches below the lowest opening of that leek.
Cut straight through the leek, forming a straight line, leaving the pale part of the leek whole. Open the leek and place it underwater.
Use hands to clean off any sand or dirt. Now, cut off the dark green tops of your leeks, keeping on the body of the leek as much as you require. Finally, discard the dark greens or save them so that you can use them later for soups!
Cut as close to the roots of the leeks as you can. This will hold the leeks together while cooking them whole.
Now that you’ve cleaned and prepped the leeks to your preference, let’s get into how to best prepare them for freezing!
Blanching The Leeks
Blanching is the best method to get crispy and tender leeks without affecting their nutrient content a lot.
Get a large pot filled with ¾ quarters of water and boil it. Then, get another bowl full of water and ice.
Now, put the trimmed and cleaned leeks into the boiling water for about 30-40 seconds. Next, remove one leek using tongs. Then, test the tenderness of leeks by inserting a knife into the stalk.
Make sure that you apply gentle pressure to insert the knife into the stalk. Then, remove the leeks from the hot water and quickly transfer them into the bowl containing cold water.
Keep it for 1-2 minutes to ensure that your leeks don’t get cooked further!
Finally, drain the cooled leeks by emptying them into a colander.
Freezing The Leeks
You can use a thick piece of cloth to dry the leeks or you can shake them out and let them air dry. It’s very important to get rid of the excess moisture, which may ruin the texture of your leeks when frozen!
Once the leeks are dry, take a greaseproof paper and line the tray with it. Then, spread the leeks on the tray. Finally, let the leeks freeze for around 1 hour to freeze the outside portion of the leeks.
Now, you can put the flash-frozen leeks into a container or freezer bag. Don’t forget to seal the bag to remove air from the inside (as much as possible). Now, you can store it right in the freezer!
Best Tips For Freezing Leeks
If you want to store leeks properly, we have come up with a list of the best tips for freezing leeks. These include:
Try Freezing Leeks Without Blanching Them
Did you know that you can store leeks without blanching? But here’s the catch: this will shorten the period for which you can freeze them. So use them before the end of 1-2 months!
You may notice a decrease in its quality after that period.
Keep Track Of When The Leeks Were Frozen
Don’t forget to label the packet in which you’ve kept your leeks with the date you had kept them in the freezer. Frozen leeks can stay good only up to 1 year. So use it before the time ends!
Go For Airtight Containers And Find The Right Freezing Temperature
Your leeks can stay fresh for a more extended period only when stored in tightly sealed containers. If they are improperly stored or frozen for too long, they may turn mushy.
Maintain your freezer at a constant temperature of 0°F or lower for them to stay fresh for a longer time.
Don’t Defrost Leeks In Certain Cases
If your leeks are frozen in thin slices, then it isn’t mandatory to defrost them! Instead, try boiling the leeks or sauteing them in melted butter!
Don’t Refreeze Your Leeks
We recommend that you do not refreeze the leeks. Freezing and refreezing the leeks leads to the breakdown of their structure.
If you do it multiple times, you may end up destroying its texture. Make sure to use a method of freezing that allows you to thaw a portion at a time.
Clean Leeks Well Before Freezing
When leeks are growing, they may collect plenty of dirt between them, especially on the outside.
Before cooking or freezing, clean them from top to bottom by cutting the roots near the base, along with any extra leafy stalks. Also, don’t forget to wash the exterior of the leeks with running water.
How Long Do Leeks Last In The Fridge?
If you have too many leeks left and want to use them quickly, we don’t recommend storing them in the freezer. Instead, store them in the fridge, and they’ll last for 7-14 days!
Before storing them in the fridge, remember to put them inside a perforated veggie bag. This will help in retaining the moisture of these delicious vegetables.
However, keep in mind that the leeks may become mushy after a couple of weeks if left in the fridge. So, if you’re planning to store it for a longer period, you may want to use an alternative that is freezing them.
Do You Need To Defrost Leeks?
The best thing about leeks is that you don’t have to defrost them! Instead, you have other options to use leeks after freezing them. These include:
- Boil: Get a proper pot of water, add a few pinches of salt to it, and let it boil. Put the leeks in the boiling water and give it some time (5-8 mins approx). The leeks will quickly thaw and help to save time!
- Saute Them: Spread some butter over a pan and place it over medium to low heat. Put your leeks on the pan and cook till it’s thawed out. Don’t use high heat immediately as this may result in the leeks remaining frozen from the center.
How To Tell If Leeks Have Gone Bad
There are chances that if you don’t store or freeze your leeks properly, they may go bad. So, if you want to know whether they’re fresh or stale, look out for the below-mentioned signs:

Finally, any foul odor is also indicative of a rotten vegetable. If you feel like the leeks smell horrible after taking them out from the freezer, you definitely need to discard them!
