FoodKeeper-based refrigerated planning reference
How long do green onions last in the fridge?
Well Stockd’s curated reference uses about 7 days refrigerated for green onions, assuming a refrigerator kept at 40°F (4°C) or below. This is a planning estimate drawn from the app’s FoodKeeper/FSIS-based catalog, not a package date or a safety guarantee.
Unopened, opened, and frozen
The single fridge number above is a planning figure. Most of the questions people actually ask about green onions turn on whether the package has been opened, so those windows are listed separately here.
- Unopened
- 1 to 2 weeks refrigerated
- Opened or cut
- Sliced green onions hold 3 to 5 days
- Freezer
- About 180 days at best quality. Frozen food stays safe indefinitely at 0°F; the window is about texture and flavour.
- How to store it
- Roots in a jar of water on the counter or fridge; they regrow. Freeze sliced, straight from the bag.
How to tell if green onions has gone bad
Dates are estimates; these are the checks that actually decide it. When more than one of these is present, throw it out rather than tasting to find out.
- Slimy white bases
- Yellow or translucent green tops
- Sour smell
How to use this window
A weekly kitchen review is frequent enough to surface this item before the catalog window passes.
Well Stockd does not know when this food was harvested, packed, purchased, opened, prepared, or moved between storage locations. Record the relevant opened, prepared, or refrigerated date, follow package directions, keep your refrigerator at 40°F or below, and use the official item listing when food safety is in question.
Primary sources and limits
The repository catalog identifies USDA FoodKeeper and FSIS typical refrigerated storage guidance as its source. FoodKeeper explains that storage times are guidelines and that actual quality varies with growing, handling, distribution, and storage conditions.
