Tips for the roasted sweet potatoes recipe
We love the simplicity of this roasted sweet potato recipe. Here are a few tips to make the best roasted sweet potatoes ever.
- You can keep the skin on if you like. Ensure the sweet potatoes are thoroughly brushed and rinsed.
- Roasting time will depend on the thickness of your sweet potato slices: the thicker, the longer.
- You can add chili powder, Cayenne, or smoked paprika to enhance the flavors of these roasted sweet potatoes.
- Swap fresh rosemary instead of thyme if you prefer. Fresh thyme is more subtle on these baked sweet potatoes, but rosemary will also work great.
Tips for buying sweet potatoes for roasting
Look for plump potatoes that feel heavy in your hand compared to their size, and with even, spotless skin without discolorations. Store sweet potatoes in a dry, cool, dark place (like a pantry or cupboard, not the fridge) for two weeks. Our favorite sweet potatoes for roasting are the Red Garnet and Jewel varieties.
How to cut sweet potatoes for roasting
To make the best roasted sweet potatoes, we recommend you first peel the skins off the sweet potatoes for better flavor and texture.
- Trim off the ends of the sweet potato and cut a lengthwise strip using your knife or a vegetable peeler with several passes: removing a thin lengthwise strip on the bottom of the sweet potato allows you to maintain the sweet potato firmly on your cutting board for cutting.
- Holding the sweet potato firmly against the cutting board with one hand, cut the sweet potato into slices. We like using a Santoku knife because the slices do not stick to the scalloped blade (Granton edge).
How long does it take to roast the sweet potato slices
This will depend on how thin you slice the sweet potatoes. Generally, the thinner the slices, the faster they cook, but as we stack them in a spiral for presentation, you can plan to roast the sweet potatoes for 35 minutes when the oven is set to 400°F (200ºC).
How to keep sweet potato leftovers
You can keep any leftovers in your refrigerator for up to 3 days. Reheat covered in the oven with a few drops of water to loosen the sauce.

My husband usually needs tons of butter and sugar on his sweet potatoes but we both loved this lighter, delicately savory recipe. I prefer fresh garlic to garlic salt, so next time I'll just chop up more garlic and use plain salt, and follow my gut instinct to cover with foil. After 30 minutes they were not cooked, but 10 more minutes covered with foil did the trick.

Switched from traditional sweet potatoes to this savory style 2 years ago. My big family LOVES this recipe. I’m making it again this Thanksgiving. It’s being requested!

Like that this is a savory sweet potato dish rather than sweet. Before I even put it in the oven, it smelled divine. Not sure I like the Italian seasoning in it. Think next time I will sub in some cumin. How much do you think I should use?

I have made these twice now, and while they taste delicious, both times they needed to be cooked for significantly longer than the recipe suggested. I put them in for 35, still had some hard potatoes, so an extra 10 minutes is what it took to get there. I don’t know if my sweet potatoes are just harder than everyone else’s, but that’s what it took.
