onion -- quartered
Onions are a good source of vitamin C, fiber, and antioxidants including quercetin; they are also low in calories and contain beneficial sulfur compounds associated with potential anti-inflammatory properties.
About
The onion (Allium cepa) is a bulbous perennial plant cultivated as an annual vegetable, originating in Central Asia and now grown worldwide. The edible bulb consists of concentric layers of fleshy leaf sheaths surrounding a central stem, with papery outer skins that range from golden-yellow to red or white depending on variety. Onions possess a pungent, sulfurous flavor when raw that becomes sweet and mellow upon cooking as sugars caramelize and volatile compounds break down. Major varieties include yellow, red, and white onions, each with distinct flavor profiles and culinary applications.
When quartered, onions are cut into four large wedge-shaped pieces, typically by first halving the bulb lengthwise through the root and tip, then cutting each half into two equal wedges. This cut is particularly useful for roasting whole or for dishes where larger pieces are desirable.
Culinary Uses
Quartered onions are employed across global cuisines, most notably in roasting and slow-cooking applications where their large surface area caramelizes deeply while the interior remains tender. They are foundational to French onion soup, where they are traditionally sliced but quartered forms work similarly; roasted vegetable platters in Mediterranean cuisines; and Indian curries where they may be quartered for specific textural effects.
The quartered form is particularly suited to techniques like sheet-pan roasting, braising, and grilling, where the wedges maintain structural integrity and develop concentrated, sweet flavors. Quartered onions pair well with root vegetables, herbs like thyme and rosemary, and are complementary in both meat and vegetable-based dishes.
