What You Need for Roasted Sweet Potatoes
Roasted sweet potatoes are our go-to whenever we need a quick veggie side (and are delicious added to any buddha bowl recipe). They require minimal prep and just a few staple ingredients including sweet potatoes and seasonings like garlic powder, salt, and pepper. A drizzle of olive oil helps crisp them up while they bake.
sweet potato tip
When choosing a sweet potato, the main thing to look for is softness or rotting. Your potato should be hard all over free of mold. If it is soft anywhere, this is a sign that it might be rotting.
It is very normal for sweet potatoes to have a little discoloration and dirt – they do come from the ground after all!

Roasted Sweet Potato Variations
Flavor: For classic roasted sweet potatoes we kept the seasoning pretty basic, but mix up the flavor by adding other spices and fresh herbs like:
- Fajita seasoning
- Taco seasoning
- Curry powder
- Cinnamon sugar
- Italian seasoning
- Chopped fresh rosemary and/or oregano
Shape: This recipe works for any shape of sliced sweet potatoes. Choose exactly how you want to slice them before baking – rounds, wedges, fries, and cubes are all great options!
What is the difference between a sweet potato and a yam?
While yams and sweet potatoes are not the same vegetable, they can often be used interchangeably in most recipes. Sweet potatoes are native to North America and yams are native to Asia and Africa.
Do sweet potatoes need to be parboiled?
Sweet potatoes do not need to be parboiled, especially if you are slicing them for roasting.
Should you peel the sweet potatoes before roasting?
It’s up to you! We prefer to keep the skin on the sweet potatoes because it helps them crisp up while roasting (and has more nutrients). If you prefer to peel the potatoes, peel them before slicing.
What’s the best way to cut sweet potatoes?
Sweet potatoes can be tough to slice through, so make sure you use a sharp knife. We use a 6-Inch Wusthof Chef Knife to slice our sweet potatoes extremely thin.
Tip: Cut the ends off of the sweet potatoes first. This creates a flat surface on the potato so you can safely continue slicing (instead of cutting a sweet potato on its curved edge).
How thick should the sweet potato slices be?
No matter what shape you cut them, the thickness should be anywhere between 1/2-inch to 1-inch. Make sure they’re all relatively the same thickness so they roast evenly.
