How can we avoid that from happening?

You might be wondering what is all about canning onions, right? The thing is canned onions are great to be used as a condiment just out of the can, in burgers, or added sauces while you’re cooking your dishes.
The procedure is quite simple and while allowing you to store your onions for up to six or seven months.
Remember however that preserving food that is not very acid (therefore with high PH), such as onions, requires pressure cooking to kill harmful bacteria that cannot be digested by the human body.
One of these bacteria is botulism, which might have severe consequences if consumed. Unfortunately, by simply boiling the food on the stovetop, you’ll not be saved from the risk, thus it is essential that you can them under pressure.
That said, canning onions is pretty simple.
The necessary ingredients are onions, salt, and a pressure canner, so you don’t need to plan before deciding to can them.
For medium-sized onions, the following procedure is recommended:
Here it is: now you have safely canned your onions and can enjoy them in a variety of meals, to add a specific and tasty flavor to your meals!
So we’ve just seen how to can onions properly, but what about storing them? Are there any other ways I can extend the onion’s shelf life if I do not have a pressure canner at home?
The good news is yes, you can. Here are some tips to better store and preserve your onions in different ways.
Even if storing onions properly is important to prolong their shelf-life, selecting the right onions is important. It would be a shame to buy old onions and all the effort spent in preserving them correctly will be vain. So let’s go over how we can choose the best onions when buying them.
As a rule of thumb, go for the onions that present dry and papery skin. Choose those onions whose outer papery layer is without spots or moisture. When picking them, onions should be firm and not ripe. Those that have begun to sprout will rot quickly, so they should be avoided.
Once you have bought the best onions, it is time to think about how to store them
Onions tend to become mushy after a while, due to their moisture-absorbing characterizing. This means, they act as “sponges” and absorb humidity very quickly and easily. With high-enough temperatures, they quickly start rotting or sprouting. It is so disappointing when you start cooking, reaching out for onion, and realize they went bad.
To prevent that from happening, try to store your onions somewhere dark, well-ventilated, and cool. It might be a cellar, basement, pantry, or garage. To ensure proper air ventilation, place them in an open wooden basket or a mesh bag. Avoid storing them inside plastic bags as they accelerate the rotting process since they do not allow proper ventilation.
Yes, we’ve said a cool place, but storing onion inside the fridge exposes them to too much cold and humidity. So do not store your onions in the fridge!
However, if you’ve cut or peeled your onions, then you should place them inside your fridge inside an airtight container. By doing so, your onions will last between 10 days to 2 weeks.
You can easily store cooked onions in the fridge, but they won’t last long, usually up to five days. Place them inside an airtight container without leaving your cooked onions outside for too long to avoid them from growing harmful bacteria (do you remember the botulism bacteria we talked about before?).
If you wish to store them for longer, consider freezing your cooked onions, they will last for as long as three months.
Freezing whole, raw onions is not recommended since it spoils the taste and the texture. However, if you’re often in a rush, you might be happy to know that you can freeze chopped onions, which turns out to be very handy for quickly sauteing recipes. Simply chop your onions, and place them inside an empty and clean ice-cube tray. Add some water to help the onions stick together and freeze. Once the “onion cubes” are frozen, place them in a resealable plastic bag inside your freezer. They will last for up to seven months
Frozen chopped onions are handy, however, they won’t have the same texture as they have when fresh. But when you add them in soups or sauteing recipes, where the texture is not as important. they do a great job.
Alternatively, another method to preserve onions is to dry them. Dried onions are delicious, not only they add the classic and tasty “onion flavor” to your dishes, but they also add that special crunchiness that can make your meals a bit more creative and “special”.
Even if it sounds complicated, the procedure of drying onions is pretty simple and does not necessarily require a dehydrator. Mind you that if you choose to dry onions in a “normal oven”, it can be done, but it will be a bit time-consuming. Furthermore, dry onions is a rather “smelly business”. If you have enough time and don’t mind the onion smell lingering over your home for a while, go ahead!
To dry your onions, simply wash them and remove the outer “paper shell”. Cut off tops and root ends from your onions and slice them into cubes. Try to have them cut in an even thickness.
If you have a dehydrator, place your onions inside the machine at 130F to 140 for 3 to 9 hours. Alternatively, place your chopped onions on a baking tray lined with baking paper and set them at the lowest temperature. Then, let them inside the oven until they are dry and check them periodically. It might take a while, but you’ll have amazing, golden-dried onions in the end!
Once the onions are dried, store them in glass jars in a cool and dry place.
Overall, onions are an important ingredient in the kitchen, a versatile “must-have” that is important to store properly so that they can last in good condition for the most extended amount of time. They come in different types and sizes.
We’ve provided you with an ultimate guide about some methods to preserve onions properly and add different flavors to your meals: enjoy!
