Recipe ingredients
- Sweet potatoes: Red-skinned, orange-fleshed. Not to be confused with yams, another sort of root vegetable with bark-like, brown skin and starchy flesh.
- It’s preferable to get some of an even size so they can cook evenly.
- One pound (450 g) of sweet potatoes (one large) will serve two as a main dish and four as a side dish.
- Olive oil
- Spices: You can use a store-bought mixture, mix your own spices, or use only salt and pepper. I used a combination of ground cumin, coriander, garlic powder, red pepper flakes, fine sea salt, and ground black pepper.
- You can add a pinch of turmeric, one of onion powder, and some dried herbs.
Alternative spices: Ras-el Hanout, curry powder (your favorite kind), Cajun spices, Italian seasoning, Herbs de Provence, a general sweet potato or plain potato seasoning mix, and so on.
Alternatively, you can make a sweet version of these sweet potato rounds and sprinkle the slices with a little bit of brown sugar and cinnamon that help bring out the natural sweetness of these root vegetables. When making the sweet version, you can use melted coconut oil or melted butter instead of olive oil.
How to roast sweet potato slices?
- Peel and cut the sweet potatoes into even, thick rounds using a large sharp knife. Place them in a large mixing bowl (1).

- Savory version: Add all the spices and toss well to coat the sweet potato pieces all over.
- Sweet version: Add cinnamon and brown sugar and toss well.
- Bake: Arrange the sliced sweet potato on a large sheet pan lined with aluminum foil or parchment paper in a single layer (2). Bake in the hot oven for about 30 minutes or until the potatoes are fork-tender (3).
Expert Tips
For perfect roasted sweet potatoes, ensure that you slice the rounds evenly; they should all be evenly thick so that they all cook evenly. The cooking time depends on the thickness of the slices.
Spread them on the baking sheet in a single layer, and use a second baking sheet if you are making a large batch. They should not be too crowded or overlapping, or the slices will steam and turn somewhat mushy instead of being nicely roasted.
The baked sweet potato recipe can be easily doubled. In this case, you will need two baking trays.
