How to season mashed sweet potatoes

Sweet potatoes are special because they take on sweet and savory flavors equally well. Here are some ideas for how to season mashed sweet potatoes:

  • In my roasted mashed sweet potatoes, I sweetened the mash with molasses and added walnuts for garnish. It’s so decadent — almost like eating a dessert! 
  • In this recipe, I went the savory route, relying on garlic, fresh thyme, and black pepper for flavor. And let me tell you, my family ate it up! The slightly spicy bite of fresh garlic coupled with minty, earthy flavor of fresh thyme works so well with sweet potatoes.
  • If you want more warmth and cozy vibes, add ½ teaspoon each nutmeg (which you can find at our online shop) and cinnamon. 
  • Not a fan of the spicy bite of raw garlic? Swap it out for roasted garlic instead, like we do in our roasted garlic mashed potatoes. You’ll have a nutty, almost sweet flavor coming through from the soft roasted garlic.

How long to boil potatoes for mash?

Sweet potatoes quickly become tender when you boil them, especially when cut into cubes. They will take around 15 to 20 minutes to soften, depending on how large the cubes are. 

To check whether they are tender enough to mash, simply pierce them with a fork or a sharp knife. If it slides in easily, your sweet potatoes are ready. 

How to make savory mashed sweet potatoes

Making this mashed sweet potato recipe is as easy as boiling a few pounds of sweet potatoes, mashing them, and lastly adding seasoning. Such a simple side dish, but sure to delight your guests at holiday parties! Here’s how to make it:

  • Cook the sweet potatoes. Add 4 pounds of peeled, cubed sweet potatoes to a saucepan and fill with water until the potatoes are covered with about 2 inches of water. Add 1 teaspoon kosher salt and bring to a boil. Once the water is boiling, reduce the heat and let the potatoes simmer. After about 15 minutes, they should be cooked through and very tender.

  • Mash the sweet potatoes. Drain all the water using a colander and return the potatoes to the pot. Mash the sweet potatoes well with a potato masher or a fork. 
  • Season the sweet potato mash. Add a good pinch of kosher salt and black pepper, 2 teaspoons fresh thyme leaves, 1 clove minced garlic, ¼ cup whole milk, and a drizzle of extra virgin olive oil. Stir to combine. 
  • Serve. Spoon the sweet potato mash into a serving bowl and use the back of a smooth to smooth out the surface of the mash to make it pretty. Garnish with fresh thyme and serve.

Serving suggestions

Sweet potato mash is one of my favorite side dishes to serve at dinner parties or to take along to potlucks. It’s easy, pretty to look at with that vibrant orange hue, and so tasty. Here’s some ideas of festive main dishes to serve it with:

Vegan mashed sweet potato recipe

This recipe is vegetarian-friendly as written, and it’s so easy to make it vegan-friendly, too! All you need to do is either swap out the whole milk for your favorite vegan alternative, or omit it altogether. Leaving out the milk will give you mash that is a bit less creamy, but it will still taste fantastic. 

If you want to keep that irresistible velvety texture, I’ve had good results replacing whole milk with an equal amount of unflavored, unsweetened almond milk. For a creamier option, you could also try unsweetened, unflavored oatmilk. 

How to store leftovers

Leftover mashed sweet potatoes will keep well in an airtight container in the refrigerator for up to 4 days. This means you could even prepare it well in advance!

I love eating leftovers for breakfast: Just fry up an egg and lay it on some warmed mash! Add a side of mixed greens, and you have yourself a filling, nutritious breakfast that will keep you going for hours!
