How Long Can You Freeze Onions?
You can freeze onions for 8 to 12 months. Raw onions are best used within 8 months or sooner. Cooked onions, however, can last for much longer.
The key is to keep them covered from being exposed to air or freezer burns.
Although onions can last in the freezer for long, it is best advised to use them up in 5 to 6 months to make the most out of their flavor.
How to Store Frozen Onions?
You can store frozen onions in any freezer-safe air-tight container or Ziploc bag. As long as it is protected from being exposed to air or freezer burn, any container would do.
The choice between the two options depends entirely on how much freezer space you have.
If you are pressed for freezer space, Ziploc bags are your best bet. You can lay the bags down flat on top of each other. This way, you can store even big batches of onion compactly.
How to Defrost Onions?
You can defrost the onions by keeping the portion you need in a bowl of cold water or the fridge for a couple of hours and letting it thaw gradually.
But if you have cut and processed the onions beforehand, it is best to use them directly into your recipe. Once it thaws, the cut or diced onions can get mushy and unappealing in texture.
Defrosted onions are best used in baking or cooking recipes, where their change in texture goes unnoticed.
Can You Refreeze Onions?
It is best recommended not to refreeze onions. Once the onions thaw, they change in texture. They lose moisture and most of their flavor along with it.
Repeated freezing and thawing will only worsen this condition.
Moreover, if the onions had been left out for long after thawing, there are high chances of bacterial build-up making it spoil sooner.
Do Onions Freeze Well?
Yes, onions freeze well, and they can last for almost a year in the fridge with much loss of flavor and freshness.
But it will lack the crunch or punch of fresh onions, so it is best used in recipes where you cook or bake it.
Though it freezes well, once it thaws, the onions can get soggy and mushy. So, they are not well suited for salads or other such raw dishes.
Though you can freeze onions as a whole, it is best advised not to. They don’t freeze as well as cut onions and are more likely to get freezer burns.
If you struggle with cutting them up, you can throw them into a food processor to mince them up before freezing them.
