onion peeled and cut in strips
Onions are low in calories and contain quercetin, a polyphenolic flavonoid with antioxidant properties. They provide vitamin C, fiber, and prebiotic compounds that support digestive health.
About
The onion (Allium cepa) is a bulbous perennial plant belonging to the Amaryllidaceae family, native to Central and South Asia and now cultivated worldwide. The edible bulb consists of concentric layers of leaf bases with a papery outer skin that ranges in color from yellow, red, or white depending on variety. When raw, onions possess a pungent, sharp flavor due to volatile sulfur compounds (particularly syn-propanethial-S-oxide); cooking mellows these compounds, developing sweet, savory notes. Common culinary varieties include yellow onions (standard, versatile), red onions (sweeter, milder), and white onions (delicate, crisp).
Culinary Uses
Onion is fundamental across virtually all savory cuisines, serving as an aromatic base for stocks, soups, sauces, and stews. When peeled and cut into strips, onions are commonly used for sautéing, stir-frying, braising, and caramelizing. French onion soup exemplifies long, slow cooking that transforms sharp raw onions into deep, sweet components. Strips also feature in Asian stir-fries, Latin soffritos, and as toppings for burgers and sandwiches. Raw onion strips appear in salads and pickled preparations. Proper cutting technique—uniform sizing ensures even cooking and consistent texture in finished dishes.
