Mashed Sweet Potatoes

The best mashed sweet potatoes, in my book, start with baked sweet potatoes—not boiled. Baking concentrates their flavor and gives them a light, fluffy texture, while boiling can make them watery or dense. My mashed sweet potatoes recipe takes a little over an hour, but most of that time is hands-off, and once the potatoes are tender, the mash comes together quickly.

They’re a natural fit for Thanksgiving, but they’re simple enough for any fall or winter dinner. Serve them with brisket, pork tenderloin, turkey, or even a store-bought rotisserie chicken. They can also be made ahead and reheated in the microwave, making them a stress-free side dish for any meal.

What You’ll Need To Make Mashed Sweet Potatoes

• Sweet Potatoes: Baking caramelizes their natural sugars, deepening their flavor and making the mash extra delicious. And don’t be fooled by labels—those “yams” in the grocery store are almost always sweet potatoes!
• Butter & Milk: Make the sweet potatoes rich, smooth, and velvety. Unsalted butter lets you control the seasoning, while the milk loosens the mash without making it too heavy.
• Pure Maple Syrup: Adds caramel-like sweetness that complements the natural sweetness of the potatoes. Be sure to use pure maple syrup rather than pancake syrup.
• Salt & Freshly Ground Black Pepper: Balance the sweetness and bring out the savory side of the dish.
• Fresh Thyme: An optional finishing touch that adds earthy freshness and a pop of color.

How To Make Mashed Sweet Potatoes

Bake the sweet potatoes: Bake the sweet potatoes whole until very soft and completely tender—this is key to getting a smooth, creamy mash. A knife should slide easily through the center with almost no resistance. Baking rather than boiling concentrates their sweetness and keeps them from becoming waterlogged.

Warm the butter mixture: While the potatoes bake, warm the butter, maple syrup, milk, salt, and pepper together in a saucepan. Warming the mixture helps everything blend smoothly into the hot potatoes.

Scoop out the flesh: Once the potatoes are cool enough to handle, split them open and scoop the flesh into the warm butter mixture. If they’re fully cooked, the flesh should be very soft and separate easily from the skins.

Mash until smooth: Mash the sweet potatoes over low heat until smooth and creamy. A potato masher or ricer gives you the best texture; an electric mixer can make the potatoes slightly gummy. If the mash seems too thick, stir in a splash of warm milk until it reaches the consistency you like. Taste and adjust the seasoning, then transfer to a serving bowl and finish with fresh thyme, if desired.

Make-Ahead Tip: These mashed sweet potatoes are a great make-ahead side dish, especially for holidays when oven and stovetop space is at a premium. They reheat beautifully; see the recipe card below for detailed make-ahead and reheating instructions.
