onions peeled
Onions are a good source of vitamin C, quercetin (a flavonoid with antioxidant properties), and fiber, particularly when raw. They are low in calories and contain inulin, a prebiotic fiber that supports digestive health.
About
The onion (Allium cepa L.) is a bulbous plant in the amaryllidaceae family, native to Central and South Asia and now cultivated worldwide. The edible bulb consists of concentric layers of fleshy leaf bases enclosing a central shoot, ranging in size from 5 to 15 centimeters in diameter depending on variety. Onion varieties differ by color—yellow, white, and red being the most common—and by pungency, which correlates with their sulfur compound content. Yellow onions are assertively flavored and store well; white onions are milder; and red onions are sweeter with a slight mineral earthiness. When peeled, the papery outer skin is removed to expose the pale, firm layers beneath, revealing the onion's true color and making it ready for cutting and cooking.
When raw, onions deliver a sharp, peppery bite; cooking gradually converts their sulfur compounds into natural sugars, progressively sweetening and mellowing their flavor. The sweetness intensifies further with caramelization, a slow cooking process that concentrates their inherent sugars into deep amber notes.
Culinary Uses
Peeled onions serve as a foundational aromatic in countless cuisines worldwide, appearing in mirepoix (with celery and carrot), soffritto, and other flavor bases. They are minced or finely diced for soups, stews, sauces, and braises; sliced for sautéing, caramelizing, or roasting; and used whole or halved for braising and grilling. Raw peeled onions are sliced thinly for salads, sandwiches, and salsas, or minced for fresh condiments. French onion soup, ceviche, Indian curries, and Italian ragù all depend critically on the allium base that peeled onions provide. They pair well with nearly all proteins, vegetables, and grains, and are equally at home in Asian, European, Middle Eastern, and American cookery.
