How to Store Green Onions Properly to Keep Them Fresh Longer

Green onions are an essential ingredient in many dishes and are often bought in bulk and stored in the refrigerator for later use. However, green onions are known for spoiling quickly. After just a few days, they can become wilted, slimy, or rotten—even when kept in the fridge.

To reduce waste and keep green onions fresh for as long as possible, try the simple storage tips below.

Storing Green Onions in the Refrigerator (Fridge Compartment)

The most common way to store green onions is in the refrigerator’s crisper or main compartment. When placed directly in the fridge without protection, green onions usually stay fresh for only about one week. In addition, storing them together with other vegetables may cause moisture buildup, affecting the freshness of both the onions and nearby produce.

To improve storage time, wrap green onions tightly with plastic wrap or food wrap to prevent moisture loss and to keep their strong smell from spreading to other foods. For convenience, divide the onions into small portions—just enough for one use—before wrapping them.

Using this method, green onions can stay fresh for up to one month.
Alternatively, you can place them in an airtight container with a lid. To prevent sogginess and decay, line the bottom of the container with a paper towel to absorb excess moisture.

Freezing Green Onions in the Freezer

Freezing is an excellent way to significantly extend the shelf life of green onions.

Start by trimming off the roots and removing any yellow, bruised, or damaged leaves. Rinse the onions thoroughly with clean water two to three times. Then, let them drain completely or pat them dry with a clean towel—this step is crucial to prevent ice crystals from forming.

Next, chop the green onions according to your cooking needs. Cut them into longer sections for stir-fries or shorter pieces for soups and garnishes.

Place the chopped onions into airtight containers or freezer-safe bags and store them in the freezer. When needed, simply take out the required amount and add it directly to your dish—no thawing necessary. For added convenience, divide the onions into small portions so you only remove what you need while keeping the rest frozen and fresh.

Storing Green Onions in Water

If your green onions still have healthy, long roots attached, you can store them using a simple water-growing method.

Prepare clean cups or cut plastic bottles. Fill them with enough water to submerge only the roots, not the white or green stalks. Place the onions upright in the container and keep them in a cool, well-ventilated area away from direct sunlight.

Change the water regularly and rinse the container to prevent bacteria buildup. With proper care, the green onions will remain fresh and may even continue growing, allowing you to harvest them multiple times.
By choosing the right storage method based on how you plan to use green onions, you can keep them fresh longer, save money, and reduce food waste in your kitchen.
