Red onions are easily recognized by their deep purple-red skin and crisp white flesh tinged with red. They have a mildly pungent flavor with a subtle sweetness, making them especially popular for raw use. Red onions add color, crunch, and a fresh bite to salads, sandwiches, wraps, and salsas. When cooked, their sharpness softens and their sweetness becomes more pronounced, making them suitable for grilling, roasting, and light sautéing. Versatile and visually appealing, red onions are a staple in everyday cooking.
