Why are these mashed sweet potatoes healthy?

How to make mashed sweet potatoes

It’s so easy to make this side dish!

First up, prep the potatoes, you can peel or not, depending on your preference. Cut them into similar sized chunks so that they cook quicker and are easier to mash. Don’t leave them whole.

Savory toppings for sweet potatoes

I keep it simple with some freshly ground black pepper and fresh herbs. But there are so many other great topping ideas for sweet potatoes that don’t include sugar, pecans, maple syrup or marshmallows. Check out some of these savory toppings:

  • Brown butter
  • Cheese: try shredded gruyere cheese or cheddar cheese, or even feta cheese
  • Roasted garlic
  • Peppers
  • Panko breadcrumbs
  • Sour cream
  • Swap the Milk: If you prefer a dairy-free version, almond milk or coconut milk can be great alternatives to low-fat milk.
  • Different Butter Options: For a richer taste, you can use full-fat butter, or to keep it vegan, opt for a plant-based butter substitute.
  • Sweet Potato Varieties: Feel free to try different types of sweet potatoes or even yams for varying sweetness and textures.
  • Spice it Up: Experiment with spices like nutmeg or pumpkin spice for a different flavor profile.
  • Herb Variations: Swap out thyme for rosemary or sage for a different aromatic touch.
  • Add-ins for Texture: Consider folding in chopped pecans or walnuts after mashing for added crunch and nuttiness.
  • Cheesy Twist: Stir in some grated cheddar or Gouda cheese for a cheesy version of mashed sweet potatoes.
  • Savory Kick: Incorporate a bit of minced garlic or garlic powder into the mash for a savory flavor boost.

Tips for making the best mashed sweet potatoes

  • Gradually add the milk to the cooked sweet potatoes. There are so many different types of sweet potatoes and the amount of liquid you might need will depend on the size and type of potato you use. So add the liquid in stages. You can always add more liquid if needed.
  • Be careful not to over-boil the potatoes. They should be cooked until fork tender, but not falling apart. If you overcook them, they will absorb too much water, resulting in a mushy consistency.
  • Make them more fluffy by adding one regular potato. Russet potatoes have a lighter texture, so you can add one to the pot and boil with the sweet potatoes. Mash everything together, and you can hardly tell there’s a white potato in there!
  • Make them vegan with quick swaps. Substitute the butter with vegan butter and use plant based milk. You will hardly tell the difference with that substitution and it makes these healthy mashed sweet potatoes vegan friendly!

How To Store Mashed Sweet Potatoes

If you have leftover potatoes, you can reheat them a couple of days later to serve again, but you can use them in so many other recipes! You can substitute them for white potatoes in this Vegetarian Shepherd’s Pie recipe, or use them to make Sweet Potato Muffins or Sweet Potato Waffles.

Can you make mashed sweet potatoes ahead of time?

Mashed sweet potatoes reheat perfectly from the fridge so they are a great side to make ahead. Let them cool to room temperature, transfer to an airtight container and they will keep well for about 3 days. You can the gently reheat them on the stovetop in a pan just before serving.

How to freeze mashed sweet potatoes?

Allow the mashed sweet potatoes to cool completely. Then place the sweet potatoes in a freezer-safe container or bag. If you’re using a freezer bag, it’s a good idea to flatten the bag and remove any air before sealing. Place in the freezer for up to 3 months for best taste.

Frequently Asked Questions

What can I do if my mashed sweet potatoes are too runny?

If the mixture is too runny, cook it on low heat for a few minutes to evaporate some moisture, or add a bit more mashed sweet potato to thicken it up.

Is peeling the sweet potatoes necessary?

Yes, for this recipe, it’s recommended to peel the sweet potatoes to achieve a smooth mash. However, the skins are edible if you prefer a more rustic texture.

How can I make my mashed sweet potatoes creamier?

For creamier mashed potatoes, add more butter or milk until you reach your desired consistency. You can also use an electric mixer for a smoother texture.

  1. I rated this recipe three stars because it has too much pepper which is not becoming to sweet potatoes. I’d actually reduce it to 1/8 teaspoon or omit.

    1. Thanks for your feedback, I also recommend seasoning to taste so feel free to reduce the pepper to suit your tastes.

  2. How many ounces of the recipee equal 1 serving…or is it a quarter or half cup. All the nutritional info is great..but knowing serving size is essential. Thankyou.

    1. The nutritional information is for one serving because every time you make it, the total weight of the recipe will be different. I recommend making a batch of the recipe, weighing it all, and dividing it by eight to get the exact weight for each serving.

    1. Hi Jon – Thanks so much for the feedback. I’m working with my ad company to improve the experience everyday!

  3. I am trying 4 of your recipes for thanksgiving this weekend. Mashed sweet potatoes would definitely be the give me more dish.
