Roasted sweet potatoes are easy to make, nourishing, and perfect as a side dish with so many meals. We love them with some baked BBQ tofu or alongside Thanksgiving dinner.

You could even enjoy them on a salad for some added nutrition or as breakfast with some tofu scramble.

The oven-baked method results in delicious sweet potato chunks that are crispy on the outside and soft in the middle. Plus, they are naturally gluten-free and vegan.


You only need 4 basic ingredients to make these oven-roasted sweet potatoes!

Ingredients laid out on a surface: pepper, salt, olive oil, and whole sweet potatoes.
  • Sweet potatoes: (Of course!) Peeled and cubed into about ½-inch to 1-inch cubes.
  • Olive oil: You can use any cooking oil.
  • Garlic, salt, & black pepper: See the section on seasoning for more ideas.

Air Fryer

To make crispy roasted sweet potatoes in an air fryer, preheat your air fryer to 400°F. Prepare the potatoes as instructed. Air fry for about 10 minutes or until tender with crispy edges.

Seasoning Ideas

There are so many ways you can add additional flavor to your roasted sweet potatoes! Here are some delicious ideas.

House Favorite:

This is my go-to seasoning mixture.

  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon paprika


A little kick, perfect for taco night, as a side dish with enchiladas, or in a taco salad!

Cinnamon Brown Sugar:

This seasoning mixture is reminiscent of sweet potato casserole.

  • 2 tablespoons brown sugar
  • ½ teaspoon cinnamon

Storing & Reheating

If you have leftovers, store the potatoes in an airtight container and refrigerate for up to 3 days.

To reheat this recipe, bake on a sheet pan in the oven for about 10 minutes at 400°F, or until they are heated through. You can also microwave them (but note they won’t get crispy again this way.)


To make oil-free roasted sweet potatoes, simply omit the oil from the ingredients. Make sure to line the baking sheet with either parchment paper or a silicone baking mat so the potatoes don’t stick to the pan. Otherwise, follow the recipe as written.
