Roasted Sweet Potatoes

These easy Roasted Sweet Potatoes are delicious enough to be eaten as a side dish, but can also be used as a base for other recipes like Sweet Potato Hash and hearty salads. 

We make these roasted sweet potatoes at least once a week in my house. They are such a great staple!

Roasted Sweet Potatoes

My toddler loves to nibble on sweet potato chunks taken right off the baking sheet, and I keep the leftovers in the fridge for throwing into various meals.

The usual is my daily lunchtime salads, but you can get creative in other ways, making hashes or pairing them with this Cilantro Jalapeño Sauce for some delicious vegetarian tacos.

It’s healthy, filling fuel ready to go, and roasting them this way brings out their natural sweetness.

How to Make Roasted Sweet Potatoes:

First you need to decide if you’re going to peel the sweet potatoes.

I personally LOVE the texture of the skin, so what I do is only peel the gnarly parts (like where my knife is pointing in the photo below), and try to leave as much of the skin on as possible:

How to Make Roasted Sweet Potatoes

If you’re leaving the skin on, I recommend buying organic sweet potatoes, and giving them a scrub beforehand.

Now it’s time to dice the sweet potatoes. First I cut them in half:

Then prop the sweet potato up on its flat side, and cut straight down to make planks:

Lay each plank down, and cut into even chunks:

Cubed Sweet Potatoes

I cut them about 3/4″ square, but you can make them as big or as small as you’d like.

Place the cubed sweet potatoes in a large bowl, and add oil, salt, and any other seasonings you’d like:

Toss well, then spread the pieces out on a sheet pan that’s large enough to hold the sweet potatoes in a single layer, with some space between:

The skins and outsides should have a nice chew and caramelization to them:

  • 3 lbs sweet potatoes
  • 3 tbsp olive oil
  • 1/2 tsp salt


  • Preheat the oven to 400F. If necessary, line the pan with parchment paper (see recipe note).
  • Decide whether or not you'd like to leave the skin on, then cut the sweet potatoes into cubes about 3/4" wide (see step-by-step photos for cutting guidance). 
  • Place the sweet potato cubes into a bowl and toss with the olive oil and salt. 
  • Spread them out on a sheet pan in a single layer, then roast for 40-45 minutes, giving everything a toss halfway through to redistribute, and keeping your eye on them at the end. They should be fork tender in the middle, with a slightly caramelized exterior. Enjoy!


Parchment Paper note: depending on your oven and the brand of sheet pans you own, the sweet potatoes may be prone to burning. When I use air bake sheet pans, I have no problems with burning, but with regular uncoated pans, the sweet potatoes close to the edges of the pan can burn. Using parchment paper helps dramatically, so if in doubt, line your pan.
