onions peeled and quartered

ProduceYear-round, though peak harvest occurs in late summer through fall (August–October in Northern Hemisphere); storage varieties remain available throughout winter and spring. Regional availability varies by cultivar and storage capacity.

Onions are a good source of dietary fiber, vitamin C, and quercetin (a polyphenolic antioxidant). They contain minimal calories and are rich in prebiotic compounds that support digestive health.

About

The onion (Allium cepa) is a bulbous herbaceous plant of the amaryllis family, native to central Asia and long cultivated across temperate and subtropical regions worldwide. The edible portion is the underground bulb, composed of concentric layers of fleshy leaf bases surrounding a central shoot, with a papery outer skin ranging from white to yellow, red, or purple depending on cultivar. The raw bulb has a sharp, pungent flavor due to volatile sulfur compounds (thiosulfates and disulfides), which become sweeter and more mellow upon cooking as these compounds break down or caramelize. Common cultivars include yellow onions (mild to pungent), white onions (sharper), red onions (slightly sweet with purple pigmentation), and sweet varieties such as Vidalia and Walla Walla.

Culinary Uses

Onions serve as a foundational aromatic in countless cuisines, appearing in mirepoix (French), soffritto (Italian), and holy trinity preparations (Louisiana Creole). They are sautéed as a base for soups, stews, braises, and sauces; caramelized for French onion soup and deep flavor development; grilled, roasted, or pickled as accompaniments; and used raw in salads, salsas, and condiments. The peeled and quartered form is particularly suited to braising, slow cooking, and dishes requiring even cooking and minimal preparation. Their sweetness emerges during long cooking, making them essential for building foundational flavors in meat stocks, vegetable broths, and complex sauces.
