How to Store Green Onions (Scallions)
Put green onions in a plastic bag in the refrigerator and use them promptly. FoodKeeper gives one week from purchase. For a surplus, wash and chop the white and green portions, then freeze for cooked dishes; blanching is not required by the Texas A&M method.
Quick answer
Refrigerate at 40°F (4°C) or below. FoodKeeper gives one week from purchase; Texas A&M separately gives six to seven days from harvest.
Purchase and harvest are different events. Those periods cannot be added, and a newly purchased bunch may already be several days old.
Rinse under running water, trim the ends and damaged areas, and chop with clean equipment. Refrigerate prepared portions in a covered container.
No new scallion-specific cut-storage period is established here. Chopping does not restart the whole-bunch purchase estimate.
Texas A&M says chopped bulbs and green portions may be put in freezer bags without blanching. Use sound, cleaned onions, seal in suitable portions and keep at 0°F (−18°C).
FoodKeeper separately lists ten to twelve freezer months from purchase. Texas A&M supplies a method but no duration, so this guide does not claim that number starts anew when you freeze the bag.
Discard immediately if
- Discard food with mold, rot, slime, or a suspicious odor; do not taste-test it.
- Discard prepared perishable food after unsafe handling or contamination.
Why guidance varies
Fresh green onions or scallions, including their green tops and white bases. Mature dry storage onions, leeks, chives, pickled onions and onion powder are outside this guide. A bunch with fresh leafy tops needs different storage from a cured bulb.
The pantry field is not the recommendation
FoodKeeper’s spring-or-green-onion row also contains a one-month pantry field. That conflicts with food-specific extension guidance to refrigerate green onions. This guide does not adopt the pantry value or apply dry-bulb-onion storage to scallions. Keeping the leafy bunch cold is the supported household choice.
Choose a useful bunch
Look for fresh green tops and sound white ends. Texas A&M advises avoiding wilted, yellowing or decayed tops. A small bruised part can be trimmed from an otherwise sound onion, but mold, slime and rot are reasons to discard affected food rather than turn it into a freezer batch.
Reserve fresh and frozen portions for different jobs
If you want a crisp raw topping, use the fresh bunch first. The freezer is useful for portions intended to flavor cooked food. Label the bag with the contents and preparation date, especially if you freeze the white bases and green tops separately. Freezing changes the texture even when the food has been handled correctly.
A finished meal has its own storage needs
Scallions mixed into a cooked dish follow that dish’s leftover rules. Cool promptly, refrigerate and use within USDA’s three-to-four-day leftover guidance; reheat to 165°F (74°C). The week listed for fresh green onions does not give fried rice, soup or a dip a week of refrigerator storage.
When to discard
Discard moldy, slimy, rotten or suspicious-smelling scallions. Keep prepared perishable dishes cold and discard them after unsafe holding, including more than two hours at room temperature or one hour above 90°F (32°C). A normal onion smell does not prove that contaminated food is safe.

Frequently asked questions
Can I keep scallions with dry onions in a cupboard?
No. Colorado State and Minnesota Extension recommend refrigeration for green onions.
Do scallions need blanching before freezing?
Not in the cited Texas A&M chopped-green-onion method. Expect a softer thawed texture.
Are spring onions and dry storage onions interchangeable here?
No. This guide uses FoodKeeper’s spring-or-green-onion entry and is limited to the fresh leafy bunch.
