1. What Are Scallions?
Scallions, scientifically known as Allium fistulosum, are a type of onion harvested for their green leaves and immature bulb. Unlike bulb onions, scallions do not form a large, well-developed bulb. Instead, they feature long, hollow green leaves that grow from a small, slender white base.
- Scallions have a mild, onion-like flavor that is less pungent than that of mature onions.
- Both the white and green parts of scallions are edible, offering different flavor intensities. The white part tends to have a stronger, more pronounced onion flavor, while the green leaves are milder and slightly grassy.
- Scallions are used in a wide range of cuisines, both raw and cooked, adding a fresh, vibrant touch to dishes.
2. Scallions vs. Green Onions: Are They the Same?
One of the most common questions is whether scallions and green onions are the same thing. The answer is generally yes, they are often used interchangeably, but understanding the nuances can be helpful.
- Regional Differences: In many parts of the world, particularly in North America, the terms “scallions” and “green onions” refer to the same plant.
- Botanical Distinctions: Technically, there can be slight botanical differences. True scallions (Allium fistulosum) are non-bulbing onions that multiply by forming clumps. Green onions, a broader term, can include young plants of other onion varieties (Allium cepa) harvested before forming a large bulb.
- Culinary Usage: Regardless of the exact variety, both scallions and green onions are used similarly in cooking. They are valued for their mild flavor and vibrant green color.
- Labeling: Keep an eye on how they are labeled in your local grocery store, as this can vary by region.

3. Nutritional Value of Scallions
Scallions are not only flavorful but also offer a range of nutritional benefits. Incorporating them into your diet can contribute to your overall health.

- Low in Calories: Scallions are low in calories, making them a healthy addition to any diet.
A study published in the Journal of Food Composition and Analysis highlighted the antioxidant properties of scallions, noting their potential role in reducing the risk of chronic diseases.

5. Growing Scallions at Home
Growing scallions at home is a rewarding experience. They are relatively easy to grow and can be harvested multiple times from a single planting.
- Planting: Scallions can be grown from seeds or from the base of store-bought scallions. To grow from store-bought scallions, place the white base with the roots in a glass of water until new green shoots appear, then plant in soil.
- Soil: They prefer well-drained soil that is rich in organic matter.
- Sunlight: Scallions need at least 6 hours of sunlight per day.
- Watering: Keep the soil consistently moist, but avoid overwatering.
- Harvesting: You can start harvesting scallions when the green leaves are about 6 inches tall. Cut the leaves near the base, leaving the roots intact so they can regrow.
- Container Gardening: Scallions can also be grown in containers, making them a great option for small spaces or balconies.
According to the University of Minnesota Extension, scallions are a great choice for beginner gardeners due to their ease of cultivation and quick growth.
6. How to Store Scallions
Proper storage is essential to keep scallions fresh and flavorful for as long as possible.
- Refrigerator: The best way to store scallions is in the refrigerator. Wrap them loosely in a damp paper towel and place them in a plastic bag or container. This helps retain moisture and prevents them from drying out.
- Water Method: You can also store scallions in a glass of water, similar to how you might root them. Place the scallions in a glass with about an inch of water, and change the water every 1-2 days.
- Freezing: While freezing scallions can alter their texture, it is a viable option for long-term storage. Chop the scallions and place them in a freezer-safe bag or container. They can be added directly to cooked dishes without thawing.
- Avoid Washing Before Storing: It is best to avoid washing scallions before storing them, as excess moisture can promote spoilage. Wash them just before you are ready to use them.
Following these storage tips can help extend the shelf life of your scallions, ensuring you always have fresh ingredients on hand.
7. Scallions vs. Other Alliums: A Comparison
Scallions belong to the Allium family, which includes other popular vegetables like onions, garlic, leeks, and chives. Understanding the differences between these alliums can help you choose the best ingredient for your culinary needs.
- Onions: Bulb onions (like yellow, red, and white onions) have a much stronger flavor and are typically used as a base for many dishes. Scallions have a milder flavor and are often used as a garnish or finishing touch.
- Garlic: Garlic has a distinct, pungent flavor that is quite different from the mild, onion-like taste of scallions. Garlic is often used to add depth and complexity to dishes, while scallions provide a fresh, green note.
- Leeks: Leeks have a mild, sweet flavor and a slightly different texture compared to scallions. They are often used in soups, stews, and gratins.
- Chives: Chives have a delicate, oniony flavor and are primarily used as a garnish. Scallions have a more robust flavor and can be used in a wider range of applications.
- Spring Onions: Spring onions have a small bulb at the base, whereas scallions typically do not. Spring onions are harvested when they are young and tender, offering a milder flavor than mature bulb onions.
| Allium | Flavor Profile | Common Uses |
|---|---|---|
| Scallions | Mild, onion-like | Garnish, salads, stir-fries |
| Onions | Strong, pungent | Base for dishes, sautéing, roasting |
| Garlic | Pungent, aromatic | Flavoring agent, sauces, marinades |
| Leeks | Mild, sweet | Soups, stews, gratins |
| Chives | Delicate, oniony | Garnish, salads |
| Spring Onions | Mild, slightly stronger than scallions | Salads, grilling, stir-fries |

Other types of alliums
Here are some other types of alliums you might find in your grocery store.
-
Ramps: Almost an onion/garlic hybrid, these sought-after wild onions can be found in wooded areas and farmers’ markets in mid-to-late spring; foraging for them is a favorite season activity for chefs and food lovers. Ramps are pinkish-white at the bottom, with a small bulb. Many foragers don’t harvest the bulbs, so the plant can grow back the following year, so you might just find the wide green leaves at the market. Ramps are often pickled and popular simply sautéed and scrambled with eggs. The bulbs tend to have slightly more onion flavor, while the leaves lean a bit more garlicky. Eat ramps raw or cooked. They can have an intense flavor, so go easy on including them in salads or as garnishes until you get a sense of how much you enjoy their flavor. The bulbs make great pickles or vinegar, and the tops are terrific added to a sauté or creamed dish like creamed spinach or sautéed kale for a fragrant punch.
-
Green Garlic: immature sprouts look a lot like scallions but are actually baby garlic. They tend to be somewhat skinnier than scallions, but your nose will know. They have a fresh garlic scent, so if you aren’t sure, just give them a good sniff. These are great to use in dishes where you want milder garlic flavor or in raw applications like salads or dressings. If you tend towards mild gastric distress with garlic bulbs, try green garlic instead; many people find the young fresh version easier to tolerate.
-
Garlic Scapes: Garlic scapes are tender young shoots that pop up in the spring with long, curving stems and a tight bud at the top. They grow from hard-neck garlic bulbs in the ground that won’t be ready for harvest until fall. Scapes have a mellow garlic flavor and can be eaten raw or cooked. Use them to make pesto, stir-fries, or pasta dishes.
-
Leeks: Leeks are alliums that are at their finest when cooked. They have the mildest flavor of all the family and, as such, the perfect choice when subtlety and delicacy are called for. Use leeks in soups, stews, quiches, or frittatas, or poach them or braise them in stock and cream for a terrific side dish. Unlike the rest of these alliums with green leaves, the dark green upper leaves are too tough and fibrous to eat; you use just the white and pale green parts. That said, you can use the greens for stock. Be forewarned that leeks grow in sandy soil that gets in between each layer. Proper cleaning is paramount, or you will have recipes full of grit. To clean leeks, cut them in half lengthwise and run them under cool water, letting the water get in between each layer. You can also slice leeks and soak them in a bowl of cold water; the sand will sink to the bottom of the bowl.
