Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Wash and scrub the sweet potatoes thoroughly to remove any dirt. Pat them dry with a kitchen towel.
Cut the sweet potatoes into evenly-sized cubes or wedges, depending on your preference.
In a large bowl, toss the sweet potato cubes with olive oil, paprika, garlic powder, onion powder, salt, and pepper until well coated.
Spread the seasoned sweet potatoes in a single layer on the prepared baking sheet, ensuring they are not overcrowded.
Roast the sweet potatoes in the preheated oven for 25-30 minutes, or until they are tender and lightly caramelized, flipping them halfway through the cooking time for even browning.
Once cooked, remove the sweet potatoes from the oven and transfer them to a serving dish. Garnish with fresh herbs if desired.
Serve the perfect sweet potatoes hot as a delightful side dish or enjoy them as a satisfying main course.
