Quick Answer

Definitely! In fact, freezing chopped onions is popular among cooks and chefs because having an ample stock lessens the work when preparing ingredients for a meal. As such, they can make better preparations of ingredients for the other recipes.

It also enables them to buy large quantities of onions without worrying of sprouting and molds. With a simple procedure and several precautionary tips, one can make frozen chopped onions that can last for weeks or months.

Can You Freeze Chopped Onions?

Unlike other vegetables, freezing chopped onions does not require blanching. In fact, blanching chopped onions will soften it to a mush.

Chopped onions tend to freeze into lumps, which is why thawing requires breaking the frozen lumps into chunks. Hitting the bag containing frozen chopped onion against the side of the counter is one way to break the frozen lumps into desired sizes.

Also, there is no need to worry about ice covering the chopped onions. Lukewarm water can easily melt the ice. Some cooks even throw in the whole frozen chunk of chopped onion into the pan as the water will evaporate in seconds.

While a sturdy moisture-free and airtight container is what most people will use for storing chopped onions for freezing, a simple bag with a locking mechanism can be space-saving. It also makes thawing easier.

However, make sure that the chosen container is airtight to avoid the onion’s odor from spreading in the refrigerator. Ideally, chopped onions stored in a good container can last up to three to six months.

Others use parchment-lined trays and quick-freezing the onions before transferring them into containers. This enables the chopped onions to freeze in batches and makes it easier to use when cooking.

How To Freeze Chopped Onions?

Everyone can make frozen chopped onions. Unlike other vegetable goods, freezing chopped onion can be done in just a minute or two. These are the basic steps in freezing chopped onions:

  • First, peel the onion and remove the undesirable layers to keep the entire batch fresh
  • Then, cut it into desired sizes
  • Put the chopped onions in a container; remember that opening the container will hasten the action of enzymes leading to spoilage or molds. As such, it is better to use several small containers than a single large one.
  • If you prefer to be more economical, several freezer bags can be more space-saving than a single large container.
  • For chopped onions placed in a freezer bag, flatten the bag containing chopped onions as much as possible before putting in the freezer to avoid an oddly-shaped, space-hogging frozen block. Furthermore, it will be more accessible and efficient this way.
