1. Yellow Onions

Yellow onions are the most common and versatile type of onion, characterized by their golden-brown skin and strong, pungent flavor. Their robust taste and firm texture make them ideal for caramelizing, as they develop a rich sweetness when cooked slowly. They are also commonly used in soups, stews, and casseroles, providing a flavorful base that enhances the overall taste of the dish.

2. Sweet Onions

Sweet onions, such as Vidalia, Walla Walla, and Maui, are renowned for their mild flavor and high water content, resulting in a sweeter taste compared to other varieties. Their low sulfur content reduces pungency, making them ideal for raw applications like salads, sandwiches, and salsas. Additionally, their natural sugars caramelize beautifully, enhancing dishes like onion rings and roasted vegetables. In contrast to sharper onions, sweet onions offer a subtlety that shines when used raw or lightly cooked, providing a delicate sweetness without overpowering other flavors. (thespruceeats.com)

3. Red Onions

Red onions are easily recognizable by their deep red to purple skin and white flesh tinged with red. They have a milder, slightly sweet flavor compared to yellow onions, making them ideal for raw applications. Their crisp texture adds a satisfying crunch to salads, salsas, and sandwiches. Soaking sliced red onions in cool water for about 15 minutes can mellow their sharpness, reducing pungency. While they can be cooked, their color may fade, and their flavor becomes milder, making them less suitable for dishes where a pronounced onion flavor is desired. (timesofindia.indiatimes.com)
