- Select the best – For best results, it’s recommended that you select the best leeks that are in their prime stage. The freshest leeks have vibrant, crisp, and bruise-free leaves and firm-yet-pliant stalks. White bulbs are another indication of freshness. Steer clear from yellow leeks as they might be infected with virus. Once you’ve separated the good from bad, you can start prepping.

You can chop crosswise to prepare pieces shaped like a half-moon. Instead of chopping, you can also cut leeks the size of a pinky finger.
- Blanch the leeks – Blanching is an essential step in the process. It locks in the flavor and keeps them fresh for long. Blanch the chopped leeks in a blanching basket under steam for 20-30 seconds. Next, drain the leeks and submerge them in cold water instantly. It will prevent them from getting overcooked.
- Dry them – You can’t freeze wet leeks. It would affect their taste and texture. Therefore, drain the liquid in a colander until the leeks are completely dry. You can pat them dry or use a fan to speed up the process, as this may take around 30 minutes.

- Store the bag in the freezer – Finally, place the bag in the freezer.
