Basic differences

Both shallots and onions are vegetables that belong to the Allium genus, which also includes other plants like leeks, chives, and garlic.

However, although onions and shallots are closely related, there are several key differences between the two.

For starters, onions are covered in papery skin, which reveals several layers of rings when peeled. They vary in size and color but are most commonly white, yellow, or red.

Unlike onions, shallots grow in clusters, and the cloves are oblong in shape, with colors ranging from grey to pale purple or brown.

Shallots also have a mild, somewhat sweet flavor, which is more subtle than the sharp, pungent taste of onions.

Additionally, while onions are often found in various dishes, shallots are less common and typically significantly more expensive.
