When it comes to cooking, even the most experienced chefs can get confused about the different types of onions available in the market. One such onion that often sparks debate is the spring onion. But what exactly is a spring onion in the UK? Is it a scallion, a green onion, or something entirely different? In this article, we’ll delve into the world of spring onions, exploring their origins, characteristics, and uses in British cuisine.
The Origins of Spring Onions
Before we dive into the specifics of spring onions in the UK, it’s essential to understand where they come from. The spring onion, also known as the Welsh onion or scallion, is a type of onion that belongs to the Allium fistulosum species. This species is native to Asia, where it has been cultivated for thousands of years. The spring onion was introduced to Europe by the Romans and quickly became an integral part of Mediterranean cuisine.
In the UK, spring onions have a long history, dating back to the 16th century when they were first cultivated in the British Isles. Today, they are grown commercially in many parts of the country, particularly in Wales, Scotland, and England.
Characteristics of Spring Onions
So, what makes a spring onion a spring onion? Here are some key characteristics that set them apart from other types of onions:
Appearance
Spring onions have a distinct appearance that sets them apart from regular onions. They have a long, thin stem with a small white or yellowish bulb at the base. The stem is typically around 6-8 inches long, with a diameter of about 1-2 inches. The leaves are hollow and tubular, with a bright green color that’s often tinged with purple or red.
Taste and Flavor
Spring onions have a mild, sweet flavor that’s slightly reminiscent of garlic. The flavor is less pungent than regular onions, making them ideal for using raw or lightly cooked in dishes. The sweetness of spring onions is due to their higher water content and lower sulfur content compared to other onions.
Growth Habit
Spring onions are perennial plants that grow from a central bulb. They can be harvested at various stages of growth, from the early “green onion” stage to the later “salad onion” stage when the bulb is fully formed. Spring onions can be grown in containers or directly in the soil, making them a popular choice for gardeners and chefs alike.
Culinary Uses of Spring Onions
Spring onions are an incredibly versatile ingredient that can be used in a variety of dishes. Here are some popular ways to use them in British cuisine:
Raw or Lightly Cooked
Spring onions can be used raw in salads, sandwiches, and as a garnish for soups and salads. They can also be lightly cooked in stir-fries, sautés, and braises to add flavor and texture to dishes.
Pickling and Fermenting
Spring onions can be pickled or fermented to create a tangy, crunchy condiment that’s perfect for adding depth to dishes. Pickled spring onions are a popular accompaniment to fish and chips, while fermented spring onions are often used in Korean and Japanese cuisine.
Roasting and Grilling
Spring onions can be roasted or grilled whole to bring out their natural sweetness. They can be served as a side dish, added to salads, or used as a topping for burgers and sandwiches.
Spring Onions vs. Scallions vs. Green Onions
One of the most common questions about spring onions is how they differ from scallions and green onions. While all three terms are often used interchangeably, there are some subtle differences:
Scallions
Scallions are typically grown from a specific variety of onion called the ‘Evergreen Hardy White’ or ‘White Lisbon’ onion. They have a stronger flavor than spring onions and are often used in Asian and Latin American cuisine.
Green Onions
Green onions are essentially the same as spring onions, but are harvested at an earlier stage when the bulb is still small and the leaves are more vibrant. They are often used in salads, sandwiches, and as a garnish for soups and salads.

What is the difference between spring onions and scallions?
Spring onions and scallions are often used interchangeably, but they are not exactly the same thing. While both are members of the Allium family and have a similar flavor and texture, spring onions are typically harvested when they are slightly more mature and have a small bulb forming at the base. Scallions, on the other hand, are harvested before the bulb forms and are typically milder in flavor.
In the UK, the term “spring onion” is more commonly used, while in other parts of the world, such as the US, “scallion” is more widely used. However, some UK supermarkets and recipe books may use the terms interchangeably, which can lead to confusion. It’s worth noting that some growers and suppliers may also use the terms differently, so it’s always a good idea to check with your supplier or recipe author for clarification.
Are spring onions and shallots the same thing?
No, spring onions and shallots are not the same thing, although they are related. Shallots are a type of onion that is harvested when mature and has a distinct flavor and aroma. They are typically grown from sets (small bulbs) and have a longer growing season than spring onions. Shallots are also typically sweeter and have a more delicate flavor than spring onions.
Spring onions, on the other hand, are harvested when immature and have a milder flavor than shallots. They are often used as a garnish or added to dishes for flavor, whereas shallots are often used in cooking and are a key ingredient in many recipes. While both can be used in cooking, they have different flavor profiles and textures, and are used in different ways.
Can I use spring onions in place of regular onions?
Yes, spring onions can be used in place of regular onions in many recipes, but keep in mind that they have a milder flavor and a sweeter taste. They are best used in dishes where a delicate onion flavor is desired, such as in salads, soups, or as a garnish. Spring onions are also great in dishes where you want a pop of color and freshness, such as in salsas or as a topping for tacos.
However, if you’re looking for a stronger onion flavor, such as in caramelized onions or roasted onions, regular onions are a better choice. Regular onions also have a higher water content than spring onions, which makes them better suited for cooking methods that require a higher water content, such as sautéing or roasting.
How do I store spring onions?
Spring onions are best stored in a cool, dry place, away from direct sunlight. You can store them in the refrigerator, either in a plastic bag or wrapped in plastic wrap, to keep them fresh for up to a week. You can also store them in a cool, dark cupboard or pantry for up to 3 days.
It’s important to keep spring onions away from strong-smelling foods, as they can absorb odors easily. You should also trim the ends of the spring onions before storing to prevent moisture from entering the bulb and causing them to spoil.
Can I grow my own spring onions?
Yes, you can grow your own spring onions! They are relatively easy to grow and can be grown in a variety of conditions. Spring onions prefer well-drained soil and full sun to partial shade. You can sow seeds directly into the ground in early spring or late summer/early fall, depending on your climate.
To grow spring onions, sow the seeds about 1-2 inches apart and ¼ inch deep. Water regularly and keep the soil moist. You can harvest the spring onions when they are about 6-8 inches tall, usually within 60-90 days of sowing. Simply trim the green tops to about an inch above the bulb, and use them in your favorite recipes.
Are spring onions a healthy addition to my diet?
Yes, spring onions are a healthy addition to your diet! They are low in calories and rich in vitamins A, C, and K, as well as potassium and fiber. They are also a good source of antioxidants and have been shown to have anti-inflammatory properties.
Spring onions also contain prebiotic fibers that can help support a healthy gut microbiome. They are also low on the glycemic index, making them a good choice for people with diabetes or those who want to manage their blood sugar levels. Overall, spring onions are a nutritious and flavorful addition to a healthy diet.
Can I use spring onions in cooking methods other than raw or sautéed?
Yes, spring onions can be used in a variety of cooking methods beyond raw or sautéed. They can be roasted, grilled, or caramelized to bring out their natural sweetness. They can also be pickled or fermented to add a tangy, sour flavor to dishes.
Spring onions can also be used in soups, stews, and braises, where they add a mild onion flavor and a pop of color. They can also be used in baked dishes, such as quiches or savory tarts, where they add a flavor and texture contrast.
