A bunch of onions in various kinds.

Where would humanity be without the onion? We would have shed far fewer tears, we would have no appropriate analogy describing our protective personalities, and our soups and sauces would be far inferior than they are now.

Onions are vegetables that belong to the amaryllidaceae family and the genus allium. They originated from central Asia and were cultivated 7,000 years ago and have been cultivated for food harvest ever since. They are very close relatives of the Chinese onion, leek, scallion, and chive.

There are hundreds of onion species, and depending on the onion variety, they will vary in overall shape, size, color, growing region, and most importantly, flavor!

Did you ever wonder what it is that makes us cry when we cut open an onion? Well, onion juice contains sulphuric acid which causes our eyes to create moisture because of the stinging sensation.

Keep reading to discover all the different types of onions! We’ll also go over all of the beautiful ways that onions can be used; from growing onions to putting them in salad dressings or French onion soup. You can make caramelized onions, pickled onion, an onion ring, and there ain’t nothing wrong with a lovely raw onion!

Onions are one of those super vegetables. Not only are they good for you, but they provide so much robust onion flavour to our favorite dishes. Sometimes the most healthy vegetables can be a little bit on the bland side (ya, I’m talking to you, kale) but that is not the case with onions! We like something a little bit more of a pungent flavour around here.

What is an Onion?

Though most of us just call it an onion, it should more appropriately be called a bulb onion, bulbing onion, or common onion. They can be grown as a biennial (usually living 2 years) or a perennial plant, but when cultivated, they are mostly treated as an annual plant and harvested after their very first growing season.

Much like a root vegetable, we actually eat the bulb, or technically the root system of the onion plant. An onion bulb is an underground stem that is shortened and compressed. The bulb itself is comprised of scale-like leaves (this is the part we eat!)

The leaves emerge very fleshy and juicy, but as harvesting season approaches, the outer foliage dies and become dry and brittle. This acts as a natural preservation tool for the onion, and why most onions don’t need to be refrigerated!

Once an onion is harvested it is ready to go as a storage onion that can be used at any time, or you can process your onions! Try a pickled onion recipe, a fermented onion recipe, or even try your hand at dry onions for an awesome garnish.

26 Different Onion Types 

1. Bermuda Onion

If you need a replacement for either Spanish onions or shallots, the Bermuda onion is what you should choose.

Bermuda onions originated on the Bermuda islands, but are also popularly grown all over the United States, especially in Texas. The Bermuda onion is commonly used raw in salads and sandwiches, but they are great for cooking as well.

2. Boiling Onion

The boiling onion is very similar to a pearl onion, though it is about twice as large. They are about an inch in diameter and round in shape. They are a great dry onion that can be kept for a long time in a pantry.

Boiling onions have a very mild flavor, though not mild enough to be used raw. They are commonly used as whole onions to be added to soups, stews, and braises.

3. Chive

Yes, chives are a type of onion, and they are perfect for making salads and soups with a little more kick. In fact, they provide a spiciness to any dish you include them in, so if you want some extra oomph for your next casserole or main dish, chives are the perfect ingredient. You can also use them in eggs and creamed soups for a little extra flavor.

Chives are most commonly used raw. Their fresh and mild spicy flavor is best depicted when they are used as a garnish, and will always ensure a necessary punch of freshness to any dish.

4. Cipollini Onion

The cocktail onion is actually an immature onion or a baby onion that is harvested before it is fully grown. The outer layer are peeled off before the onion is pickled. They’ve got a super pungent flavor!

The classic vesper martini is garnished with a cocktail onion. To be honest, they are more of an outdated garnish (we all remember what happened to the sun dried tomato) and they are not commonly used in cooking as much.

6. Creole Onion

Small and red, Creole onions are very spicy, and they are perfect for adding a little kick to your dish. They are mostly grown in southern climates and have been used in Creole cuisine for centuries.

7. Egyptian Onion

Egyptian onions

The Egyptian onion is also known as the Egyptian walking onion. It gets this name because it’s odd growing pattern. Basically the plant produces bulblets where flowers would usually grow.

Green onions are interesting because their flavor changes the closer you get to the bulb. The very tips of the plant that are most dark green will have a more mild flavor and a more dried leaf, and the lower down you go the juicier and more flavorful the plant becomes.

9. Leek


Leeks are very versatile onions and they go great with meats, such as bacon. If you’re cooking something slowly from scratch – including stews and soups – they are the perfect ingredient to add. In fact, you can find many soup recipes that include leeks if you search the Internet.
