Tired of having your onions sprout or go soft before you get a chance to use them? Find a great deal on onions at the store? Or did you have a great onion harvest but not a great place to store them all?
Whatever your scenario, here’s some info on storing onions that will help them last longer.
Onions keep very well under the right conditions. These conditions are:
- Cool. Preferably 4- 10°Celsius or 40-50° Fahrenheit; just above fridge temperature and below room temperature. Too hot (your kitchen pantry) and your onions will sprout. Too cold (your fridge) and your onions will go soft and start tasting funny. A cool room or a spot in the garage (when temperatures are above freezing) are good storage places.
- Dry. Onions pick up moisture very easily which will lead to rot – if you have high humidity, it’ll be tricky to keep onions for a long time. If you do choose to store them in the refrigerator, keep them in a crisper with low humidity.
- Dark. Changing light conditions cause fluctuations in temperature and humidity, both things that onions do not enjoy.
- Ventilated. Keep onions in a mesh bag or in a single layer to ensure air can get at them. DO NOT store in plastic bags. You could even store them in old pantyhose – insert one onion, twist the pantyhose, insert next onion, repeat. An interesting decor item!
- Isolated. Onions do off-gas and will affect the flavor of food around them, it’s best they have their own space. Store onions and potatoes separately as they will make each other spoil quicker.
If you’ve got a cold room you’re set – simply hang your onions in a mesh bag and you’ll have fresh onions whenever you need them.
We don’t have any space in our house that’s the right temperature and our detached garage experiences the full effect of our Manitoba winters. Storing our big onion haul from the garden is an issue. For me, freezing and dehydrating onions, as I explain in these two posts complete with You Tube videos, is a great alternative.
