Differences between Onion and Shallot
Contents
Comparison Article[edit]
Onions and shallots are culinary staples from the Allium genus used in cuisines worldwide. Though botanically related, they possess distinct differences in growth, appearance, flavor, and culinary application. Both are cultivated varieties of the species Allium cepa, but belong to different cultivar groups.[1]
Botanical classification[edit]
The common onion belongs to the Allium cepa var. cepa group. It typically reproduces from seed or by planting immature bulbs known as sets. The shallot is classified within the Allium cepa var. aggregatum group.[1][2] This group also includes the potato onion. Shallots primarily reproduce vegetatively, with a single planted bulb dividing into a cluster of several smaller bulbs.[3][4][5]
Physical characteristics[edit]
A primary physical distinction is their growth habit. Onions grow as individual, single bulbs, whereas shallots form clusters of multiple bulbs attached at the root base, similar to garlic.[3] Onions are generally larger and have a round or ovoid shape. Shallot bulbs are smaller and more elongated. Internally, the layers of a shallot are typically finer than those of an onion.
Flavor and culinary use[edit]
Shallots have a milder and sweeter flavor profile compared to the more pungent taste of most common onions. This difference influences their use in cooking. The delicate taste of shallots makes them suitable for raw applications, such as in vinaigrettes and salads, where a strong onion flavor might be overpowering.[3] When cooked, shallots tend to caramelize more quickly than onions and break down to create a finer texture in sauces. Onions, with their stronger flavor that holds up to longer cooking times, are often used as a foundational ingredient in stocks, stews, and roasts. While they can often be used interchangeably, it is generally recommended to use about three shallots to replace one small onion.
Comparison table[edit]
| Category | Onion | Shallot |
