Healthy mashed sweet potatoes

Potatoes may have gotten a bad rap over the years, but good news: they’re actually good for you. And sweet potatoes are some of the healthiest foods of all time. But of course, it all depends on the preparation: if they’re slathered in cream and butter, those health benefits don’t have quite the same shine. Sweet potatoes are incredible roasted, and mashing them is just as tasty. Keep reading for the secret ingredient in this healthy mashed sweet potatoes recipe!

How to make healthy mashed sweet potatoes

This healthy mashed sweet potatoes recipe our take on the traditional white mashed potatoes. Sweet potatoes are a nutritious superfood, full of potassium and nutrients. Garlic and chopped chives add nuance and freshness to the flavor.

Now, what’s the mysterious secret ingredient? When testing this recipe, we found that on their own, mashed sweet potatoes have a wet, gooey texture. In fact, they’re completely underwhelming! Adding some Yukon gold potatoes in this recipe help the sweet potatoes stay together with a texture that’s more like what you’d expect from mashed potatoes.

Notes on these healthy mashed sweet potatoes

These mashed sweet potatoes are a fantastic healthy side dish that works with just about any meal! Here are a few notes on this recipe:

  • This recipe was born out of a recipe fail — a sweet potato shepherd’s pie that used a similar potato mixture for the top. It’s always encouraging when failure can result in success! (Isn’t that how breakfast cereal was invented?)
  • Adding goat cheese crumbles on some leftover potatoes was fabulous; a good embellishment if you’re looking for one.
  • We’re taking a poll on photography style: do you prefer your potatoes dramatic (the first and second photos), or subdued (third photo)?

How to reheat mashed sweet potatoes

If you have leftover mashed sweet potatoes, the best way to reheat them is on the stove with a splash of milk. Scoop the leftover potatoes into a small saucepan and turn the heat to medium-low (if you crank the heat up too high, the potatoes might burn on the bottom or you may dry them out). Reheat them with the lid on and let them cook for 10 to 15 minutes, stirring every 5 minutes or so. I recommend letting the mashed sweet potatoes cook for a few minutes before adding in the milk, since they may loosen up on their own as they steam in the saucepan.

Ready in just 30 minutes, these healthy mashed sweet potatoes are flavored with garlic and fresh chives. Perfect for Thanksgiving or any winter meal.

  1. Dramatic potatoes for the win! :) I love the sounds of this recipe and in my opinon, sweet potatoes > regular potatoes any day! We’ve already had our Thanksgiving here in Canada but there’s no way I’m waiting until next year for these. They’ll be happening very soon!

  2. I have to try out how to make this one. My first attempt to make sweet potato mash failed so badly. Since then I never gave it another chance… it might be time. :)

  3. I love the first photo, the action shot. But then I pinned the recipe, and I chose the non-action shot (the one with the chives, but without the hand). Turns out that while I love the composition of the first photo, apparently I think extra hands are distracting on my Pinterest boards. Go figure :)
