– 2 yellow onions
Yellow onions are a good source of fiber and vitamin C, and contain quercetin, a flavonoid antioxidant with anti-inflammatory properties. They are low in calories (approximately 40 per 100g) and contain organosulfur compounds that contribute both flavor and potential health benefits.
About
The yellow onion (Allium cepa) is a bulbous vegetable belonging to the allium family, native to Central Asia and now cultivated globally. Characterized by its papery golden-brown outer skin and pale yellow interior flesh, the yellow onion possesses a pungent, sulfurous aroma when raw that mellows and sweetens significantly upon cooking. The bulb typically measures 2–4 inches in diameter and consists of concentric layers of edible tissue surrounding a central shoot. Yellow onions are the most versatile and widely used onion variety in Western cuisine, prized for their balanced sweetness and savory notes that develop through caramelization and extended cooking.
Culinary Uses
Yellow onions serve as a foundational aromatic in countless dishes across global cuisines, forming the base for soups, stews, stocks, and sauces in French cooking and beyond. They are sautéed as a flavor base (mirepoix when combined with celery and carrot), roasted until caramelized to develop deep sweetness, grilled for char, or sliced raw into salads and relishes. Their ability to transform texturally and flavor-wise across cooking methods—from pungent raw to rich and sweet when caramelized—makes them indispensable in both everyday cooking and professional kitchens. Common applications include French onion soup, stir-fries, curries, and as a component in countless condiments and prepared foods.
