Ingredients

Scale

Sweet Potatoes

  • 3 large sweet potatoes (about 2.5 pounds total), peeled and cut into 1-inch cubes

Seasoning and Coating

  • 4 tablespoons olive oil, divided
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (optional, for a little heat)
  • 1 teaspoon kosher salt, or to taste
  • 1/2 teaspoon black pepper, freshly ground
  • 2 tablespoons cornstarch

Garnish

  • Fresh parsley, chopped (for garnish)

Instructions

  1. Prep Sweet Potatoes: Peel the sweet potatoes and cut them into roughly 1-inch cubes. Rinse the cubes under cold water using a colander, then thoroughly dry them with paper towels to ensure crispiness during roasting.
  2. Combine Spices: In a large bowl, whisk together smoked paprika, garlic powder, onion powder, cayenne pepper (if using), kosher salt, and freshly ground black pepper to create the seasoning mix.
  3. Add Oil and Spices: Drizzle 2 tablespoons of olive oil over the sweet potato cubes and toss to coat evenly. Add the combined spice mixture and toss again until every piece is well coated with the spices.
  4. Cornstarch Coating: Sprinkle the cornstarch evenly over the seasoned sweet potatoes and toss once more to coat thoroughly. This helps enhance the crispiness of the roasted potatoes.
  5. Preheat Oven: Set your oven to 400°F (200°C) and allow it to fully preheat for even roasting.
  6. Prepare Baking Sheet: Line a large baking sheet with parchment paper to prevent sticking and aid in even cooking.
  7. Arrange Sweet Potatoes: Spread the sweet potato cubes in a single layer on the prepared baking sheet. Avoid overcrowding, which can cause steaming instead of roasting. Use two baking sheets if necessary.
  8. Roast: Place the baking sheet in the oven and roast the sweet potatoes for 20 minutes, allowing them to start cooking and getting slightly crisp.
  9. Flip and Roast Again: Remove the baking sheet and carefully flip the sweet potatoes to promote even browning. Drizzle the remaining 2 tablespoons of olive oil over the potatoes and return the sheet to the oven. Roast for an additional 15 to 20 minutes until the sweet potatoes are tender inside and crispy and caramelized on the outside.
  10. Check for Doneness: Test a cube by piercing it with a fork; it should be tender and easily pierced. The edges should be golden brown and crispy.
  11. Garnish and Serve: Remove the sweet potatoes from the oven and sprinkle chopped fresh parsley over the top for a burst of color and freshness. Serve warm as a delicious side dish.

Notes

  • Drying the sweet potatoes thoroughly before roasting is key for achieving maximum crispiness.
  • Using cornstarch helps to create a crispy crust on the sweet potatoes.
  • Ensure sweet potatoes are spread in a single layer without overcrowding to allow proper roasting.
  • The optional cayenne pepper adds a subtle heat but can be omitted if you prefer milder flavors.
  • For extra crispy results, flip the sweet potatoes halfway through roasting and drizzle with additional olive oil.
  • Use parchment paper or a silicone baking mat to prevent sticking and facilitate easy cleanup.
