Can you freeze leeks? Leeks are available year-round, but if you bought these vegetables in bulk, you’ll need to save the rest for future recipes. We don’t recommend freezing leeks as these vegetables have a high water content, but it can be done to avoid waste. This method can be used to store excess leeks, although the veggies might get soaking wet after thawing.

Should You Freeze Leeks?

The freezing temperature could affect the texture of the leeks. These vegetables tend to ooze a clear, sticky liquid when cut, which is something to keep in mind when preparing these vegetables for freezing. For example, if texture is important to the dish, there is no way to restore the leeks’ crispy texture after freezing. On the other hand, if you’re freezing leeks for cooking, then the texture of the vegetable isn’t as important. When cooked, the texture of frozen and fresh leeks is similar.

Choosing and preparing the leeks

Freezing affects the overall quality of the veggies, so it makes sense to choose the best leeks you can get your hands on. Choose leeks with a vibrant color, firm stems, and crisp, blue leaves. The stalks of the leeks should be flexible but firm, the bulb should be white. Avoid leeks with brownish ends or those that are wilting or turning yellow.

After choosing the highest quality leeks you can find at your local grocery store, rinse the greens well under running water. Thoroughly clean the stems, removing any dirt and debris that has become lodged between the leaves.

After rinsing and cleaning the leeks, pat the vegetables dry with a paper towel and trim the leeks. You can either cut the leeks into equal slices or roughly chop them before freezing. Since the leeks will get soaking wet after freezing and thawing, it’s best to slice the veggies while they’re fresh. After trimming the leeks, you’re ready to pack the veggies for freezing.

Freezing the leeks to freeze

Blast freezing helps preserve the nutritional value and flavor of the leeks. To prepare the leeks for blast freezing, line a baking sheet with waxed paper or aluminum foil.

Lay the leeks in a single layer, being careful not to let the vegetable pieces touch each other. Place the baking pan in the freezer and allow the leeks to freeze for about an hour or two.

While you wait for the leeks to freeze, prepare a freezer-safe, resealable plastic bag.

After an hour or two, remove the leeks from the freezer and place the frozen leeks in the resealable plastic bag.

Before sealing, squeeze out as much air as possible. Write down the storage date, then store flat in the freezer.

Direct Freeze

If you want a no-fuss way to freeze leeks, you can simply freeze these vegetables straight. Simply cut the leeks into the desired size, then prepare a freezer-safe, resealable plastic bag.

Place the chopped leeks in the plastic bag and squeeze out as much air as possible before sealing. Write down the storage date and then store the leeks flat in the freezer. This method is best for short-term storage only.

Blanch the leeks for freezing

Blanching the leaves is a good way to preserve the color of the leek. This step is optional but recommended.

Prepare a pot of boiling water and a bowl of ice water. Using a colander, dip the chopped leeks into the boiling water and blanch the greens for 1 to 2 minutes.

Once the leeks turn light green, remove them from the water and plunge them into ice water. Once cool, place the blanched leeks on a paper towel and pat dry. Prepare a resealable plastic bag for freezing.

Place the chopped leeks in the plastic bag and squeeze out as much air as possible before sealing. Write down the storage date and then store the leeks flat in the freezer.

Shelf life, thawing and reheating suggestions

If stored in the freezer, the leeks will stay fresh for at least 3 months. However, since vegetables tend to decompose quickly once thawed, use up your supply as soon as possible.

To thaw frozen leeks, simply add the veggies directly to the dish you are cooking. The heat will thaw the frozen vegetables almost instantly. However, if you’re using the leeks for garnish, you can defrost them by letting a packet of frozen leeks thaw on the kitchen counter. The leeks should be ready to use after an hour.


Can you freeze leeks? While leeks are available year-round, you may want to stock up and freeze the leeks from time to time. The freezing process is very simple: wash, cut, blanch if necessary and freeze the leeks. Keep in mind that freezing leeks is best only if you’re going to use them in cooked dishes. Just remember these storage tips to preserve the natural flavor and color of the leeks!
