White onions have a clean, sharp flavor with a hint of sweetness, making them a versatile choice for both raw and cooked dishes. Their crisp texture and bright white skin add freshness and crunch to salads, salsas, and sandwiches. When sautéed or grilled, they develop a mellow, slightly sweet taste that enhances soups, curries, and stir-fries. Popular in Mexican and Mediterranean cuisines, white onions offer a balanced flavor that complements a wide range of recipes.
