About Roasted onion

Roasted onion is a simple yet flavorful preparation often used in a variety of cuisines, including American, European, and Middle Eastern dishes. Onions are thought to originate from Central Asia and have been used for their culinary and medicinal properties for thousands of years. When roasted, onions develop caramelized sweetness due to the Maillard reaction, making them versatile in soups, salads, and side dishes. Nutritionally, onions are low in calories and contain dietary fiber, vitamin C, vitamin B6, manganese, and antioxidant compounds like quercetin, which may contribute to health benefits. They also contain potassium, which supports numerous bodily functions.
