These oven roasted sweet potatoes are a lightened up take on the classic candied yams. Soft and creamy on the inside and crispy on the outside, with the spice of cinnamon and ginger and a lot less sugar than you’d expect. Ideal for Christmas or Thanksgiving. Try them once and these sweet potatoes will be a welcome addition to your table any time of the year.
Originally appearing on the blog in December 2016, the post was last updated in November 2020.
I have been known to make lunch out of a single sweet potato with a bit of butter, ginger, and cinnamon. It’s easy, delicious, and comes together in about 8 minutes using the microwave.
While planning out the holiday content in 2016 year, I knew I had to figure out how to transform that lunch dish into an amazing holiday side dish. The goal was to create a dish that isn’t candied or marshmallowed. Something that let the flavors of the sweet potato shine.
Behold: oven roasted sweet potatoes. Pillowy soft on the inside, kind of like the inside of a baked sweet potato, with crispy sweet outsides. They are like little bites of sweet potato perfection and since their introduction they have stayed a reader favorite here on the blog.
Prepping the Sweet Potatoes
I am not a fan of sweet potato skins, so I peel them, but that step is optional and shouldn’t change the cooking time or temperature. Aim for even slices,, about 1/4″ thick, so that they cook evenly.
The long, skinny sweet potatoes work better, as they are easier to slice evenly than the thicker ones.
On the baking sheet they should be touching but not overlapping. You are welcome to line your baking sheet with foil if you like. On one hand it will reduce your mess, but on the other hand it may take a little longer to bake.
Seasoning the Sweet Potatoes
There are a few reasons that I opt to use a pastry brush to apply the butter, instead of tossing them in a mixing bowl. The brush helps the butter go on more evenly. It also lets you use a lot less butter.
The most important reason is that cold sweet potatoes will cause the butter resolidify. Even with storing my sweet potatoes in a kitchen drawer, in the winter those potatoes are cold!
Sprinkly the spice mixture directly on each buttered potato, doing your best to avoid getting it on the pan. If too much of the spice mixture gets on the pan, it may burn and can cause the potatoes to stick. Stuck on potatoes are never fun and burnt brown sugar and spice doesn’t taste very good.
Oven Roasting Sweet Potatoes
I have a thing for roasting vegetables in the winter time. It not only brings out the natural sweetness of the vegetables, but it also calls for less hands on time. Whether we are talking about a quick weeknight dinner or a big holiday spread, dishes that taste amazing while requiring less attention are always a good thing!
Typically I roast vegetables at 425º. This allows the veggies to soften without becoming mush while the outside caramelizes just enough.
However, for these oven roasted sweet potatoes we want the inside to be like mush. That’s how we get the creamy baked potato texture on the inside. Starting with a cooler oven allows the insides can cook more thoroughly without the outside burning. I’ve found 375º to be the sweet spot.
Broiling the Sweet Potatoes
While the first part of the cooking process makes the insides super soft, finishing them under a low broiler makes the outside crispy.
Caution: Food under a broiler can burn quickly. Do not place anything under the broiler then walk out of the room. Keep an eye on it. Use your oven light if possible. Check after the first minute, then again every 30 – 45 seconds.
If your broiler doesn’t have a high/low option, leave the oven door slightly open to reduce the heat. The potatoes are done when the edges start to brown and the sugar on top caramelizes.

Oven Roasted Sweet Potatoes Recipe
Oven roasted sweet potatoes are a delicious addition to your Christmas or Thanksgiving dinner table. Crispy on the outside with buttery soft insides, these sweet potatoes embrace the natural flavor of the sweet potato without a lot of added sugar. Once you try them, you’ll be enjoying them all year long.
Best served hot and fresh from the oven, but will keep in the fridge for a couple days. To bring back that crispy texture, reheat in a 375º oven until they are sizzling hot. About 10 minutes.
