Fresh red onions, also known as purple onions, featuring deep red or purple skin and white to reddish-purple flesh. These versatile onions have a mild, sweet flavor that ranges from crisp and mild to slightly spicy and pungent, making them ideal for both raw and cooked applications.
Red onions are excellent for raw use in salads, sandwiches, salsas, and as garnishes where their vibrant color and crisp texture shine. They can also be cooked in various ways including sautéing, grilling, roasting, or caramelizing to bring out their natural sweetness. Use them in soups, stews, stir-fries, or grill them on skewers for a tender, slightly charred side dish.
Red onions are packed with nutritional benefits. They're rich in anthocyanins and quercetin, powerful antioxidants that support heart health, help fight inflammation, and may reduce the risk of chronic diseases. They contain prebiotics like inulin and fructooligosaccharides that support digestive health by promoting beneficial gut bacteria. Red onions are also a good source of B vitamins including folate and vitamin B6, which support metabolism, red blood cell production, and nerve function. Despite being low in calories, they provide valuable fiber, vitamins, and minerals that may help support bone health and immune function.
