The green onion, also known as chives, green onion or cambray onion, is one of the most versatile ingredients in Latin American cuisine. It brings flavor, color and aroma to soups, stews, salads, omelettes, sauces and a host of other preparations. However, it is also one of the vegetables that spoils most quickly: in a few days it can turn yellow, soft or develop a bad smell inside the refrigerator.
The good news is that there are simple methods to keep it in perfect condition for months, and even up to a year. Below, we explain step by step how to achieve it at home, with ingredients and utensils that you probably already have available.
Why green onion goes bad so quickly
The green onion is largely composed of water, which makes it particularly delicate. When stored inside closed plastic bags or in damp places, its leaves begin to ferment and become filled with moisture. On the other hand, if left exposed to air without protection, it dehydrates and loses its characteristic bright green color.
The secret to extending its shelf life is to control two key factors: humidity and temperature. Once you understand this, keeping it for long periods becomes really simple.
Advance preparation: the step you can’t skip
Before storing it, it is essential to prepare the green onion correctly. Follow these steps:
- Select the best pieces: choose fresh, firm onions with an intense green color. Discard yellow or wilted leaves.
- Wash carefully: Rinse each stem under running water to remove dirt and debris. You can use water with a little vinegar for a deeper clean.
- Dry completely: this step is crucial. Any remaining moisture will accelerate deterioration. Use paper towels or a clean cloth and let it sit in the air for a few minutes.
- Cut according to your preference: you can chop it into thin slices, separate the white part from the green part or leave it in larger pieces depending on the use you are going to give it.
Method to keep it for up to a year in the freezer
The freezer is your best ally to keep the green onion fresh for long periods. Here is the detailed procedure:
1. Uniform chopping
Once dry, cut the onion into small, even pieces. This makes it easier to use later, as you can take just the right amount without having to defrost the entire content.
2. Packaged in airtight container
Place the chopped onion in glass jars with tight-fitting lids or cold-resistant zip bags. If you use bags, press gently to extract as much air as possible before closing them.
3. Labelling
Write down the date of packaging on the container. In this way, you will be able to keep track and consume it within the recommended period.
4. Freezer storage
Store the containers in the freezer. The onion will remain in optimal conditions for up to twelve months, preserving its characteristic flavor and aroma.
Alternative: oil storage
If you prefer to avoid the freezer, another option is to keep the green onion in oil. To do this, chop the stems, place them in a sterilized jar and cover them completely with vegetable or olive oil. Store the jar in the refrigerator and consume within the next two months. This method also provides a flavored oil ideal for dressings.
How to use frozen green onion
One of the great advantages of this method is that you don’t need to defrost the onion before using it. Simply take the amount you require and add it directly to your preparations. It is ideal for:
- Homemade soups and broths
- Sautéed vegetables or meats
- Tortillas, omelets and scrambled eggs
- Rice, stews and stews
- Fillings for empanadas or pies
Keep in mind that frozen onion loses a little of its crunchy texture, so it is not the best option to consume raw in salads. However, for any cooked preparation it works perfectly.
