What are the edible parts of onion?

* Bulb: This is the main part of the onion, the round, fleshy base that we typically think of as the onion itself. It's made up of layers of overlapping leaf bases, and it's the most commonly eaten part.

* Greens: The green, leafy tops of the onion plant are also edible. These are often called "onion tops" or "scallions" and they have a milder flavor than the bulb.

While you can eat the entire onion bulb, including the skin, the outer skin is usually removed before cooking or eating.
