1.1 Scallions vs. Green Onions: Are They Different?
Scallions and green onions are essentially the same thing. The name varies regionally; in some areas, they’re labeled as scallions, while in others, they’re known as green onions. Both terms refer to the same plant with a mild, fresh taste.

Compared to mature onions, scallions have a much milder taste. They lack the sharpness of yellow or red onions, providing a subtle oniony note that doesn’t overpower other ingredients. This makes them ideal for dishes where you want a hint of onion without the intense bite.
2.2 Raw vs. Cooked Scallions: Flavor Differences
When eaten raw, scallions offer a crisp, fresh flavor with a slight bite. Cooking mellows their flavor, making them sweeter and more subtle. Raw scallions are great in salads and as garnishes, while cooked scallions blend well into soups, stir-fries, and omelets.
3. Culinary Uses of Scallions
Scallions are incredibly versatile in the kitchen, suitable for a wide range of dishes.
3.1 Raw Applications: Salads, Garnishes, and More

3.2 Cooking with Scallions: Soups, Stir-fries, and Omelets
In cooked dishes, scallions can be sautéed, stir-fried, or added to soups and stews. They’re a common ingredient in Asian stir-fries, adding a mild onion flavor that complements soy sauce and other seasonings. Scallions also work well in omelets, quiches, and frittatas, providing a subtle, savory note.

Here are some frequently asked questions about scallions, along with answers to help you better understand this versatile vegetable.
10.1 Are Scallions and Chives the Same Thing?
No, scallions and chives are not the same, although they are often confused. Scallions are a type of young onion with a mild onion flavor, while chives are herbs with a delicate, grassy taste. Chives are thinner and more tubular than scallions. According to The Spruce Eats, “Chives are herbs in the Allium family, which also includes onions, garlic, shallots, leeks, and scallions. All have a characteristic oniony or garlicky flavor, although chives are the mildest of the bunch.”
10.2 Can You Regrow Scallions from Scraps?
Yes, you can easily regrow scallions from scraps. Place the white base of the scallion with the roots in a glass of water, and new green shoots will start to grow. Change the water every few days. Once the shoots are a few inches long, you can plant the scallion in soil. As stated by the University of Minnesota Extension, “Instead of tossing those scallion ends, place them in a glass with about an inch of water. Set the glass on a sunny windowsill, and change the water every day or two. The scallions will start to regrow in just a few days.”
10.3 How to Prevent Scallions from Sliming in the Fridge?
To prevent scallions from becoming slimy in the fridge, make sure they are dry before storing them. Wrap them in a dry paper towel and place them in a plastic bag. Avoid storing them in a tightly sealed container, as this can trap moisture and promote sliming. According to Food52, “The key to keeping scallions fresh is to prevent them from getting too wet. Wrap them in a dry paper towel before storing them in a plastic bag.”
