These vegan mashed sweet potatoes are deliciously savory and sweet and made with herbs, aromatics, and tangy dairy-free yogurt for a healthy side dish perfect for any occasion.
Gluten-free, WFPB oil-free, with a nut-free option.
Don't you think sweet potatoes deserve some new opportunities? Especially for Thanksgiving? I mean, love a good maple-sweetened, pecan-topped sweet potato casserole as much as the next person, but I also love trying new things!
Since sweet potatoes are wonderfully sweet on their own, I decided to add savory notes, mash 'em up, and let the contrasting flavors do their thing.
Why this Recipe Works
Tangy plain dairy-free yogurt gives these vegan mashed sweet potatoes irresistible flavor. It actually tricks your brain into thinking there's dairy in there somewhere (of course, there's not).
The yogurt also adds creaminess without the need for any butter, oil, or milk. I honestly don't think anyone would EVER guess this recipe is oil-free. And thanks to the yogurt, you won't miss the vegan butter at all!
As mentioned above, another thing we love about this dish is the contrast between the savory onion, garlic, and rosemary and the natural sweetness of the potatoes. The rosemary is subtle, and the saltiness supports the sweetness without overpowering it.
This is also a great, fuss-free dish to prepare in advance, whether you're cooking for a busy holiday meal or just a quiet dinner at home. You can bake the sweet potatoes the day before, and you'll need less than 30 minutes to finish the dish before serving.

- sweet potatoes - organic sweet potatoes tend to be much more flavorful than conventional.
- fresh rosemary - this really is one of the best parts of the dish, so I don't recommend skipping or replacing it!
- rubbed sage - a classic holiday flavor
- onion and garlic - I like to use yellow onion in this dish, though white onion and shallots are also great.
- pecans - look for raw pecans. These are quickly toasted in a pan before sauteing the onion, garlic, and herbs.
- plain vegan yogurt - this adds a deliciously tangy undertone, complementing the savory notes, and makes the mashed sweet potatoes so creamy. Kite Hill makes an amazing Greek-style plain yogurt. Or try one of my homemade yogurt recipes:

How to Make Savory Sweet Potatoes
- Cook the sweet potatoes: I prefer to bake the sweet potatoes because it enhances their flavor, and that means you don't have to chop them! But you can also peel, chop, and boil the sweet potatoes. Bake in a 400 degree oven for about an hour or until very soft. Next, let them cool for about 20 minutes or until cool enough to handle.
TIP: The sweet potatoes can also be cooked a day or two in advance and refrigerated until you're ready to prep the dish.
- Peel the cooked sweet potatoes and discard the skins. Place the sweet potatoes in a large bowl.
- Toast the pecans: In a saute pan over medium-low heat, toast the nuts for about 5 minutes or until fragrant. Transfer to a plate to cool, then roughly chop and set aside.
- Sauté the veggies: Cook the onion until translucent, then add garlic, vegetable broth, rosemary, sage, and black pepper. Cook for several minutes or until most of the broth has evaporated.
- Assemble and serve: Add about ½ cup dairy-free yogurt to the bowl with the sweet potatoes. Mash to incorporate. Add the onion mixture and season with salt. Stir well, taste, and add more yogurt, salt, or pepper, as desired. Transfer the sweet potatoes to a serving bowl, and garnish with a swirl of yogurt and chopped pecans.

Savory Vegan Mashed Sweet Potatoes
- 3 pounds organic sweet potatoes (about 6 small/medium sweet potatoes)
- ½ cup raw pecans - See Notes re: nut-free.
- 1 small sweet onion, finely chopped
- 4 cloves garlic, minced
- ½ cup vegetable broth
- 2 teaspoons chopped fresh rosemary
- scant ½ teaspoon rubbed sage
- black pepper
- ½ to ¾ cup plain, unsweetened vegan yogurt plus more for garnish - See Notes.
- ¾ teaspoon fine sea salt
Bake the sweet potatoes:
- Preheat oven to 400 degrees F, and line a baking sheet with foil. Wash and dry the sweet potatoes and prick each one a few times with a fork.
- Place sweet potatoes on baking sheet and bake for 1 hour, flipping them at the halfway point, or until a knife slides in easily. Let cool for about 20 minutes or until cool enough to handle. Alternatively, sweet potatoes can be baked 1 to 2 days in advance and refrigerated until ready to peel and proceed with the recipe.
Toast the pecans and saute the veggies:
- Preheat a saute pan over medium-low heat. Toast pecans in the pan, stirring occasionally, for about 5 minutes or until fragrant. Transfer pecans to a plate to cool, then chop and set aside.
- Return saute pan to the burner and increase heat to medium. Cook the onion for about 5 minutes or until translucent, stirring occasionally. Add broth and garlic to the pan, and cook 3 to 4 minutes. Add rosemary, sage, and pepper, and cook until most of the broth has evaporated and onions are softened. Remove from heat.
Assemble the dish:
- Peel the sweet potatoes, discarding the skins, and place in a large bowl. (If potatoes were made in advance and are still cool, warm them in the microwave or on the stovetop.) Add about ½ cup yogurt to the bowl, and use a potato masher or fork to mash the sweet potatoes. Add onion mixture and salt, and stir to combine. Taste and add more yogurt, salt, and pepper, as desired.
- Transfer mashed sweet potatoes to a serving dish. Garnish with a swirl of yogurt and chopped pecans.
