Storing Onion Doesn’t Have to be Hard
If you have a whole onion that you need to store, you will want to put it into the right container and then put them away from the light in a cool and dry place. If you let your onion get wet or expose it to the sun, it might sprout!
Once your onions are prepared, they will keep for a couple of days in the fridge, but that is it. This is why the freezer is really your best friend when you are trying to store onion properly.
Make sure that you have quality freezer bags on hand or invest in some ice cube trays. You will want to have freezer bags that will not cause freezer burn, and you will need ice cube trays that you use just for this purpose.
Onion smell can be hard to get out of products of all kinds, and plastics and different materials are porous enough to hold onto the onion smell. Having separate storage containers for this need is always a good idea because of this.
Freezing Caramelized Onion
If you have any leftover caramelized onion that you need to store, you will want to make sure that you wash your hands before you start the storing process.
Bacteria that get into the bags or ice cube trays can destroy your onion well before you have a chance to use it for anything.
It is always a good idea to make sure that your hands are clean before you start working on any kind of storage process.
If you are using freezer bags, spread out the caramelized onion in a thin layer inside the bag. When you seal the bag, make sure that you press out all the air. You will want to double-check that the bag is fully sealed as well.
Place the bag of onion somewhere where it will not get folded up or compressed while it is freezing. You want your onion to stay on a thin sheet inside the bag.
This freezing method prevents clumps of onion that can get wet and moldy, and it makes it much easier to get out the onion that you need when you are cooking.
You will simply break off a corner or a part of the sheet of frozen onion when you need some and then seal up the bag and put it back in the freezer.
If you are using ice cube trays for your caramelized onion storage, you will want to be sure that you consider lining the trays with some plastic wrap. This will help to prevent the smell from escaping from the ice cube trays into the rest of your freezer.
You will simply place an equal amount of caramelized onion into each of the ice cube tray slots and then fold the plastic wrap closed over the top of the onion ball.
Store your caramelized onion trays in the freezer in an out-of-the-way location. This will prevent the smell of onion from getting into other foods that are stored with them in the freezer.
Either of these storage methods will make your caramelized onions last for about a month. This will help you to be able to make all kinds of recipes without having to plan too far in advance, and it can also save you time chopping, slicing, and preparing onion when you are hungry and just want to be able to eat.
Onion that is stored this way thaws out very quickly as well, and it is simple to make room to store your onions in this way when you have a regular size fridge and freezer.
