Banana shallots are large bulbs, averaging 10 to 18 cm in length, and have an elongated shape with tapered, pointed ends. The bulb is encased in a papery, outer layer that is smooth and ranges in colour from tan, light pink, to grey-brown. Once the brittle layer is removed, the surface of the bulb is firm, and there may be multiple cloves fused together, tinged with purple or green hues depending on the specific variety. Within the cloves, the flesh is ivory to white, crisp, and multi-layered. Banana shallots have a flavour reminiscent of both onions and garlic, but the taste is much milder with subtle sweet notes.
