of a small onion

A small onion, typically referring to varieties such as pearl onions, boiling onions, or cipollini onions, which are immature or naturally diminutive cultivars of the common bulb onion (Allium cepa). These onions are distinguished by their compact size, ranging from ¾ to 1½ inches in diameter, with papery skins that may be white, yellow, or reddish depending on variety. The smaller size results in proportionally thicker, more concentrated layers and a sweeter, more delicate flavor compared to standard onions, with less pungency and a tender texture when cooked. Pearl onions and boiling onions are often bred specifically for whole cooking and presentation, while cipollini onions are flat, disk-shaped Italian varieties prized for their inherent sweetness.

Small onions are valued for their ability to be cooked whole, maintaining visual appeal and creating a tender, integrated dish component. They are central to French garnishes (petits légumes), pearl onion-based stews and braises, and Mediterranean preparations. Cipollini onions are frequently roasted, glazed, or caramelized to emphasize their natural sweetness, while pearl and boiling onions appear in creamed dishes, peas with onions, and as cocktail garnishes (pickled). Their compact size and reduced cooking time make them suitable for quick sautéing, boiling, or inclusion in composed vegetable dishes.
