About Roasted red onions

Roasted red onions are a flavorful addition to various cuisines, often used in Mediterranean, Indian, and Western dishes for their caramelized sweetness. Originally native to Central Asia, red onions are rich in antioxidants and phytochemicals that contribute to their deep purple color. They are low in calories (approximately 40 calories per 100g), high in fiber, and a good source of vitamin C, vitamin B6, and manganese. Their roasting process enhances their natural sugars, making them tender and flavorful, while preserving much of their nutritional content.
