Onions, Cooked

EverydayCooked

Cooked onions are softened, caramelized allium vegetables that develop a sweet, mellow flavor through heat application, contrasting sharply with their raw pungency. The cooking process breaks down their cellular structure, enhancing digestibility while preserving beneficial soluble fiber and prebiotic compounds that support gut health. This versatile foundational ingredient appears sautéed, roasted, or grilled in global cuisines, adding depth to dishes from soups to stir-fries without significant added calories when prepared without oils or fats.
