The term "green onion" is usually used interchangeably with "spring onion" and "scallion", though technically scallions are younger and have a less-developed white bulb. Green onions deliver a lot of the flavor of regular bulb onions, but for less carbohydrate, since only the bulb part has significant carbohydrate.

Green Onions 101

Green onions are available year round have bright green tops with a firm white base that includes small shoots of bulb onions that are mild tasting relative to large bulb onions. They have an underdeveloped white bulb and green stalks that are long. The entire green onion is edible. Scallions generally do not have a bulb. They are generally eaten raw, but can also be roasted, grilled or sauteed whole or chopped.

How to Store Green Onions

Storing green onions is easy. Just remove any packaging such as rubber bands or leaves that have been damaged. Wrap them in a plastic bag and store them in the vegetable crisper section of your refrigerator. They should not be stored more than 5 days and may even wilt or lose their crispness in as little as 2-3 days depending on how fresh they were when you bought them.

Store green onions separately from foods that are sensitive to onion odors such as mushrooms or corn, which will absorb the odor of the onions and affect their flavor.
