The most common types of onions are what you probably have sitting in your kitchen. There are dozens of different varieties of onion, with most of them being readily available to consumers. The onion isle at the farmer’s market can seem a bit overwhelming, even to experienced cooks.

A few of the most famous onions used in various ways and recipes include scallions, Vidalia’s, yellow onions, white onions, shallots, and red onions.

  • Scallions or green onions

They are better known are one of the most commonly used of the onion varieties. They are extremely versatile and easily recognized by most home cooks. Scallions are long thin onions, with a green pipe-like shape and white bulb at the ends.

  • Red onions

How to Properly Store Onion’s

Proper onion storage, for most of us, means tossing them in a basket on the kitchen counter and leaving them there until they are all used or until we notice they have gone wrong and tossed them out. But, is this method an ideal way to keep our onions fresh?

Onion naturally has a longer lifespan, longer than most vegetables. Unlike most vegetables, green onions are the only variety of onion that should be refrigerated. Other onion's all thrived more in a dark, dry climate and should be stored accordingly. Rather than just tossing them in the bottom of the pantry, try placing them in a paper bag with holes punched in it for them to breathe.

This method, along with others such as hanging them in pantyhose, will double the overall lifespan of your onions. Onions should only ever be stored in the refrigerator or freezer after they have been sliced or chopped. In these instances, the remaining onion should be placed in a zip top bag or air tight container.

How Long Can Onion’s Last?

The life span of your onions has a great deal to do with which type of onion you are storing. Sweeter onions, such as Vidalia’s, have a shorter lifespan. They have a higher moisture content and less acid in them to keep them, fresher, longer.

While, other onion species, such as white and red, have a far longer shelf life. The life span of onions all depends on how they are stored. If you place them on the counter in a basket or even in a dark drawer in a basket, you will get around 1-2 months out of the onions before they rot or sprout.

As for sweeter onions, that lifespan is cut in half, and you will most likely see them begin to rot after 3-6 weeks. Properly storing your onions in a dark, dry area and prolong the life up to 3-4 months for most onions and 1-2 months for the sweeter varieties.

Onions that have been sliced and appropriately stored in the refrigerator can last for up to a week. When frozen, these onions have a lifespan of 6-8 months but may experience a textural change when thawed.

Conclusion

Whether you are an onion lover or you simply use them when it is required in a recipe, the vast variety of onions is one that can transform any home cooks flavor profile, just by experimenting with something different.
