A Brief Introduction
Shallots and onions are both staple ingredients in kitchens worldwide. They both belong to the allium family, which includes garlic and leeks, and can replace each other when one is out of stock in the kitchen.

However, despite these similarities, they differ in several important ways, such as size, flavour, texture, and nutritional value. In this article, we will explore the difference between shallots and onions, helping you understand when to use each in your cooking and how their unique characteristics can elevate your dishes, particularly in Indian and South Indian cuisine.
What Are Shallots?
Shallots are small, bulb-like vegetables that belong to the allium family, which also includes onions, garlic, and leeks. Known for their delicate, sweet, and slightly tangy flavour, shallots are widely used in cooking, especially in gourmet recipes. Their colour ranges from rose-red to golden brown, and the inside flesh is pulpy white with hints of green. They are most likely native to Southeast Asia, went to India, and then, via commerce and regular agricultural migration, made their way to the Mediterranean region. Shallots have been grown for thousands of years; they are mentioned in Greek historical and literary works.

Furthermore, Africa does not cultivate them. Shallots are widely used in the sambhar preparation in South India, and they impart a distinguished flavour and aroma to the dish compared to regular onions.
Key Differences Between Shallots And Onions
Size And Shape
One of the easiest ways to tell shallots and onions apart is by their size and shape. Shallots are typically much smaller and more elongated than onions. They are shaped like garlic, with smaller bulbs growing together in clusters.
On the other hand, onions are larger, rounder, and grow as a single bulb. The outer skin of onions varies in colour, like yellow, red, or white, while shallots range from rose-red to golden brown, and the inside flesh is pulpy white with hints of green. This smaller size and more compact structure give shallots a delicate appearance compared to the robust, round form of onions.

Flavour And Texture
When it comes to flavours, shallots are often described as a cross between garlic and onions. They have a milder, sweeter taste with a hint of garlic-like sharpness. This makes shallots an excellent choice for recipes that require a subtle flavour without the overpowering punch of onions. Shallots are one of the main ingredients in a South Indian sambhar or many kinds of stews. They are also brined and pickled to be served on the side with many Indian meals, especially those that comprise of roti and gravies for an added layer of crunch and flavour.
Onions, on the other hand, have a much stronger and more pungent flavour. When raw, onions can taste quite sharp, though cooking them often brings out their sweetness. The texture of shallots is finer and softer, which allows them to break down easily in dishes. They are caramelised to make gravies, sliced and used in stir-fries, or even served raw on the side with many Indian meals like fish curry and rice, fried meat starters, naan, and gravies. In contrast, onions are firmer and provide a more substantial texture in cooking.
Growing Pattern And Structure
Another notable difference between shallots and onions lies in how they grow. Shallots grow in clusters like garlic. When you plant one shallot bulb, it multiplies and produces several smaller bulbs clustered together.

However, this is different from onions, which typically grow as a single large bulb per plant. Because shallots grow in clusters, they can be harvested similarly to garlic, while onions are harvested one at a time. This unique growth pattern also makes shallots more compact and easier to store in small spaces compared to onions, which need more room for storage.
Nutritional Value
Are shallots more beneficial to health than onions in terms of antioxidants? Compared to most other members of the onion family, they are believed to have higher flavonoid and phenol antioxidants, although they are used less frequently in recipes. This puts them among the top foods that reduce inflammation and combat a variety of chronic illnesses by lowering the damage caused by free radicals, as per research.
