Sour Cream Mashed Sweet Potatoes are a luxuriously creamy, low-carb side dish that complements any autumn meal or weeknight dinner.

A blend of sour cream and butter gives these mashed sweet potatoes a rich, velvety texture and a satisfying savory finish. Besides the dairy, this recipe uses just a few pantry staples—salt, black pepper, and paprika—so you can make it quickly without fuss.
This dish takes less than 25 minutes from start to finish, with most time spent hands-off while the potatoes simmer. Because sweet potatoes have natural sweetness, there’s no need to add sugar or other sweeteners. The result is a balanced side that highlights the potato’s natural flavor.
To prepare, peel and cut the sweet potatoes into evenly sized chunks, then boil them 15 to 20 minutes until very tender. Drain and return them to the pot, then mash with butter, sour cream, salt, pepper, and a touch of paprika. A handheld potato masher works well, but you can also use a ricer for an even smoother consistency.

Sweet potatoes are a good source of dietary fiber and have a lower glycemic index than many other starchy vegetables, which means they tend to be digested more slowly. That slower digestion helps prevent rapid spikes in blood sugar while still providing a naturally sweet, comforting taste.
These mashed sweet potatoes work beautifully for holiday menus, Sunday roasts, or as an easy complement to grilled or roasted chicken on a busy weeknight. The creamy sour cream and butter make every spoonful indulgent while the paprika adds a subtle, warming color and mild smoky note.
