Create perfectly roasted sweet potatoes with crispy edges and a tender, caramelized interior. This easy side dish works for weeknight dinners or holiday feasts.

Ingredients

Scale
  • 3 large sweet potatoes, peeled and cut into 1-inch cubes
  • 3 tablespoons olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1 teaspoon tapioca starch or cornstarch (for extra crispiness)
  • Optional Sweet Glaze: 1 tablespoon maple syrup or honey

Instructions

  1. Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). Line a large baking sheet with parchment paper. Do not overcrowd the pan; use two sheets if necessary to ensure the potatoes roast instead of steam.
  2. In a large bowl, combine the sweet potato cubes, olive oil, kosher salt, black pepper, and garlic powder. Toss well to coat every piece evenly.
  3. Sprinkle the tapioca starch (or cornstarch) over the potatoes and toss again until the starch disappears. This step helps achieve the desired crispy exterior.
  4. Spread the seasoned sweet potatoes in a single layer on the prepared baking sheet(s).
  5. Roast for 20 minutes. Remove the pan from the oven. If you are using the optional sweet glaze, drizzle the maple syrup or honey over the potatoes now and gently toss them on the pan.
  6. Return the potatoes to the oven and roast for another 10 to 15 minutes, or until the edges are deeply golden brown and caramelized, and the centers are soft when pierced with a fork.
  7. Serve immediately as a healthy roasted vegetable side dish.

Notes

  • For the crispiest results, make sure your oven is fully preheated and do not skip the starch coating.
  • If you prefer a savory roasted sweet potatoes flavor, omit the maple syrup/honey and add 1/2 teaspoon of dried rosemary or thyme with the initial seasonings.
  • These are excellent for meal prep; reheat them in a toaster oven or air fryer to restore crispness.
