Onions are part of the allium family, which includes garlic, leeks, chives, ramps, and hundreds of other species of aromatic plants. Even among onions, there is a boatload of varieties, each with its own distinct characteristics.

Even though they’re used in various dishes and cuisines, they’re still one of the most underappreciated ingredients on the grocery list, constantly present but sometimes forgotten.

How many different varieties of onions can you name? Is it four or six? Most of us are familiar with the everyday yellow onion found in supermarkets. You may have also eaten red or white onions, but there are many more onion kinds to pick from. Continue reading to learn about several onion varieties you may not have heard of or seen before.

Before we get into some of the rarer kinds of onions, let’s talk about the common varieties;

Basic types

Yellow onions

Yellow onions are one of the most popular onions found in supermarkets. They’re a must-have in any pantry. Raw, they’re abrasive, but sautéed, roasted, or caramelised, they’re sweet. Because of their high starch content, it doesn’t turn to mush even after long cooking times, making them an excellent all-purpose cooking onion.

White onions

White onions have a strong, pungent flavour and should only be used when you want a strong flavour. They come in white or somewhat brown tint and can be used in several different meals, including salads and general cooking. The skins of these onions are thinner and more papery. They are significantly more flavorful when cooked, but be aware that slicing them up is the most painful part!

Red onions

Raw red onions are sharper and spicier than yellow onions. The skin of these onions is deep purple, and they have a mild flavour. Some people consider red onions to be spicy, whereas others consider them to be just right. Soak them in ice water while you prepare the rest of your ingredients to make them extra crisp and to remove some of their sharpness.

Sweet Onions

The peel of this onion is pale yellow. They are larger and have less translucent skin than yellow onions. They’re gentle, crisp, and refreshing because they have less sulphur and more water than yellows, reds, and whites. Sweet onions lack the harsh, intense flavour of ordinary onions, and they are actually rather sweet. The look of this onion is occasionally squished or flattened. Sweet onions should be kept in the refrigerator because they are a lot more perishable.

Sweet onions are the way to go if you’re seeking for onions to utilise in a recipe that showcases their flavour (like onion soup) or for caramelising.

Texas 1015 is a thick-skinned, round, softball-sized yellow onion with crisp, juicy, non-tearing white flesh and a pleasant, sweet scent. These sweet onions are known as the “million dollar baby” because it took ten years of intensive research, never-ending testing, and a million-dollar budget to develop an onion with luscious, crisp flesh and a mild, extraordinarily tasty sweet taste.
