½ medium onion
Onions are rich in vitamin C, fiber, and quercetin (a powerful antioxidant flavonoid), while being low in calories. They contain prebiotic fiber that supports gut health and have been linked to anti-inflammatory and cardiovascular benefits.
About
The onion (Allium cepa) is a bulbous perennial plant of the Amaryllidaceae family, domesticated in Central Asia and now cultivated globally. The edible bulb comprises concentric layers of fleshy modified leaves that vary in color from white and yellow to red, depending on cultivar. Onions are characterized by a pungent aroma and sharp, slightly sweet flavor that mellows and becomes caramelized with cooking. Raw onions contain sulfur compounds responsible for their characteristic bite, while cooking breaks down these compounds into sweeter sugars.
Culinary Uses
Onions form the foundation of countless savory dishes across world cuisines, appearing in Italian soffritto, French mirepoix, Spanish sofrito, and aromatic bases for Asian stir-fries. They are sautéed as a foundational building block for soups, stews, and sauces; caramelized for sweetness and depth; grilled or roasted whole; sliced raw in salads and sandwiches; or pickled for condiments. Their versatility extends from enhancing stock to serving as a primary vegetable component, making them indispensable in both French and home cooking.
