The amount of green leek stems you use depends mainly on the dish you’re cooking. For instance, when making stocks, most of the stem can be used, but when stir-frying or braising, only the white part should be included.

Clean the whole leeks:

To give leeks a proper clean, slice them in half lengthwise and keep the root intact. Rinse off any dirt or sand with running water several times to ensure everything is removed. Doing this will provide an extra level of hygiene and safety.

Clean the chopped leeks:

To cut leeks for recipes, remove both the root and the dark green leafy parts. Slice the white stalk in half lengthwise, then chop crosswise in a half-moon shape. This will ensure you have nice chopped leeks ready to use in your dishes.

Place your chopped leeks in a bowl and fill with cold water. Vigorously swirl them around so the dirt will settle to the bottom. Give it a few minutes, then scoop out the clean pieces using a slotted spoon.

If you’ve got a large amount of leeks to clean, you can use a colander and large bowl of water to do this quicker. Put the chopped leeks in the colander, then submerge it partially in the bowl. Swish around the leeks to clean them then pull up the colander to drain quickly.

Freezing (without blanching)

Freezing (without blanching)

Wondering if you can freeze fresh leeks? Absolutely. Blanching the leeks ahead of time is said to help maintain their quality, but in my experience, there’s not much of a difference between raw and blanched leeks regardless.

Rather than blanching them, you can easily preserve leeks without it – just follow these instructions:

  1. Slice the white and pale green parts of leeks into either circles or half-moon shapes.
  2. To clean the leeks, put them in a bowl of water and use your hands to gently agitate the water and remove any dirt.
  3. After slicing leeks, place them in a colander to drain. You may want to rinse them with cold water if there is still any dirt attached.
  4. After patting the leeks dry, arrange them in a single layer on a lined baking sheet & place it in the freezer to let it get solid within 1 to 2 hours. Make sure that the baking sheet is placed on an area where it won’t get accidentally bumped.

It’s possible to add frozen leeks to a meal at any time during the cooking process or sauté them while still frozen.

Frozen leeks can be quickly made usable again with either your microwave’s defrost setting or by holding them under cold running water, lightly pressing the frozen pieces until they become softer. This is great for making dishes with smaller sized leeks like shredded or diced.

Following this, you can treat the leeks as if they were purchased from a store. This will give you the same results as if you had bought fresh leeks.

People often think frozen vegetables require special treatment compared to fresh veggies, but that’s not the case. All they need is a little extra time amounting to their frozen condition while preparing. In all other aspects, both fresh and frozen vegetables should be treated the same way.

You can use frozen leeks in many dishes and you won’t need to make any modifications since the taste of frozen leeks is equivalent to that of freshly harvested ones.

Frozen leeks need to be cooked differently depending on how they were prepared. If the leeks simply got cut and frozen, they require a longer cooking time compared to those that went through blanching first. This is why it is essential to blanch vegetables before freezing them.

Having pre-cooked vegetables in your pot is much easier than trying to cook frozen and uncooked ones. It helps you save time and energy, and ensures that your dish is cooked to perfection.
