Mashed sweet potatoes are a popular side dish made by cooking sweet potatoes until they are soft and then mashing them into a smooth or chunky consistency. They are often seasoned with ingredients like butter, salt, and pepper, and can be enhanced with spices such as cinnamon or nutmeg for added flavor. This dish is not only delicious but also nutritious, as sweet potatoes are rich in vitamins A and C, fiber, and antioxidants. They are commonly served during holiday meals, especially during Thanksgiving, and can be enjoyed year-round as a versatile accompaniment to various main dishes.
