There is an ongoing debate among chefs concerning white onion vs red onion. Most people use the term onion to refer to both kinds of onions. However, it is crucial to know their differences as it could affect your recipe.

And this article will examine white onion and red onion and compare them against each other in a head-to-head match. But what is the difference between white onion and red onion?

White onions tend to be a bit milder than red ones, but this isn’t always true as the onion’s growing conditions can affect its flavor profile. Also, red onions tend to hold their color when you cook them, so they’re great for adding color to salads or making salsas.

We’ll talk more about all these shortly; for now, let’s learn more about these two types of onion!

What is White Onion?

White onions are small, oblong-shaped onions with a very mild flavor; and are white-skinned with white flesh. They have a crisp, papery outer skin that’s easy to peel off, with a sweeter flesh than yellow onions but not as sweet as red onions.

Furthermore, white onions are excellent for grilling or charring because the high moisture content prevents them from burning as easily as other types of onions do.

They also work well in salsas and chutneys and can be pickled. White onions are mild enough to be eaten raw.

However, the onions are not pure white.

Rather, they are more of a pale purple-grey color, but when you cook them, the sugars caramelize and give them their characteristic brownish-white color on the outside of the onion.

White Onion Vs Red Onion: Key Differences

While white and red onions share many similarities, they also have major differences that make them better suited to different uses.

White onions are great for cooking because they are milder, sweeter, and more versatile than red onions.

They are lighter in color, making them great for adding slices to sandwiches or salads where you want a strong onion flavor but not an overbearing visual presence.

They also cook down nicely when you’re making a soup or stew that needs a lot of onions as a base flavoring but don’t want the final result to be too strongly oniony.

On the other hand, red onions are bolder and more intense than their white counterparts.

Where white onions are mild enough to eat raw—and even taste delicious that way —you’ll probably want to cook with red onions most of the time.

Their burgundy color makes them ideal for cocktails or as a garnish for dishes like guacamole, salsa, or soups to add pops of color without detracting too much from the overall appearance your dish.

Well, they contain a higher amount of compounds called disulfides and thiosulfinates. These compounds are what give sweet onions their distinctly sweet flavor.

Which Onion Is Best For Cooking?

There are tons of onions out there. Red, white, yellow, and even purple fit a wide variety of recipes. But the question remains: Which onion is best for cooking?
