Green onions, also known as scallions or spring onions, are young onion plants harvested before the bulb fully forms. They offer a crisp, juicy texture with a mild, fresh onion flavor that is less pungent than mature bulbs. Nutritionally, they are exceptionally low in calories while providing a notable amount of vitamin K and a good source of vitamin C.

↓ Full nutritionPeople love green onions for their bright, sharp flavor that can be used raw as a garnish or cooked to add a sweet, savory depth to dishes. Their versatility and long shelf life in the refrigerator make them a staple for instantly elevating the taste of soups, stir-fries, eggs, and sauces.
For some, the raw flavor can be slightly harsh or cause mild digestive discomfort like heartburn. Those on blood-thinning medications (e.g., Warfarin) should be mindful of their vitamin K content and maintain consistent intake. To counteract digestive issues, try sautéing them lightly to mellow the flavor, or pair them with other ingredients in a dish rather than consuming large amounts alone.
The hollow, tubular green leaves of a green onion can be used as a natural piping bag for filling with soft cheeses or dips.

What's the difference between green onions and scallions?
They are the same thing. 'Green onion' and 'scallion' are common names for the same plant (Allium fistulosum or young Allium cepa). 'Spring onion' can sometimes refer to a slightly more mature plant with a small bulb, but the terms are often used interchangeably.
Can you eat the entire green onion?
Yes, both the white bulb end and the hollow green stalk are edible. The white part has a stronger, sharper flavor and is often cooked, while the green tops are milder and commonly used raw as a garnish.
How should I store green onions to make them last?
Wrap them loosely in a damp paper towel and place them in a plastic bag in the refrigerator's crisper drawer. Alternatively, stand them upright in a jar with an inch of water, cover loosely with a bag, and change the water every few days.
