Roasted Garlic Mashed Sweet Potatoes

Some side dishes earn a permanent spot on your rotation. This is one of them.

Mashed sweet potatoes have a lot going for them on their own — natural sweetness, a creamy texture, and a color that makes any plate look better. But add a full head of roasted garlic, and the whole thing shifts into something deeper and more savory, with a richness that balances out the sweetness perfectly.

This dish works for a regular Tuesday dinner just as well as it does for a holiday table. It comes together without much fuss, uses simple ingredients, and somehow always gets people asking for the recipe.

Why You’ll Love This Recipe

The roasted garlic is the real star here. Roasting mellows the sharp bite of raw garlic and turns it into something soft, sweet, and almost nutty — nothing like the harsh flavor you’d get from adding raw or sautéed garlic instead.

The sweet potatoes themselves mash up incredibly smooth and creamy, especially when you take the time to roast them instead of boiling. Roasting concentrates their natural sugars and keeps the texture from getting watery.

This recipe is also forgiving. You can make both the garlic and the sweet potatoes ahead of time, then mash and season everything right before you’re ready to eat. It reheats well, stores well, and scales up easily if you’re feeding a crowd.

It’s a side dish that does a lot of the heavy lifting without requiring much from you.

Ingredients

• 3 lbs sweet potatoes (about 3–4 medium)
• 1 whole head of garlic
• 3 tablespoons olive oil, divided
• 3 tablespoons unsalted butter
• ¼ cup heavy cream or whole milk, warmed
• 1 teaspoon kosher salt, plus more to taste
• ½ teaspoon black pepper
• ¼ teaspoon smoked paprika (optional, but recommended)
• Fresh thyme or chives for garnish (optional)

Instructions

Preheat your oven to 400°F (200°C).

Slice the top off the head of garlic to expose the cloves. Drizzle with about 1 tablespoon of olive oil, wrap it loosely in foil, and place it on a baking sheet.

Scrub the sweet potatoes and poke them all over with a fork. Rub them with the remaining 2 tablespoons of olive oil and place them on the same baking sheet alongside the garlic.

Roast everything for 45–55 minutes, until the sweet potatoes are completely tender when pierced with a knife and the garlic cloves are golden and soft. The garlic may be done a few minutes before the sweet potatoes — if so, just pull it out early.

Let everything cool for about 10 minutes, until you can handle it comfortably.

Squeeze the roasted garlic cloves out of their skins directly into a large bowl — they should slide right out. Use a fork to mash them into a smooth paste.

Peel the sweet potatoes (the skins should slip off easily) and add the flesh to the bowl with the garlic.

Mash everything together with a potato masher or hand mixer. Add the butter and warm cream, mashing and stirring until you reach your preferred consistency — chunky or completely smooth, both work well.

Season with salt, pepper, and smoked paprika. Taste and adjust as needed.

Transfer to a serving dish and top with a pat of butter and a sprinkle of fresh thyme or chives if you’d like. Serve warm.

Tips & Notes

Make it ahead: Both the sweet potatoes and garlic can be roasted up to two days in advance and stored in the fridge. When you’re ready to serve, warm the sweet potato flesh in the microwave before mashing.

Reheating leftovers: Add a splash of cream or milk when reheating to bring the texture back to life. Leftovers keep well in the fridge for up to 4 days.

Dairy-free option: Swap the butter for vegan butter and use full-fat coconut milk in place of the heavy cream. The coconut flavor is mild and works nicely with the sweetness of the potatoes.

Add some heat: A pinch of cayenne or a drizzle of chili oil on top adds a nice contrast to the sweetness.
