Preheat the oven to 450° F. In a small bowl, mix together salt, pepper, brown sugar, chili powder, paprika, and garlic powder.
Slice the potato into 1/2 inch thick rounds, then into 1/2 inch equal sized cubes.
Toss sweet potatoes in olive oil, then add seasoning and toss to coat.
Place the seasoned sweet potatoes on a baking sheet with about a half-inch in between each one. Sprinkle with a pinch of brown sugar. Roast for 15 minutes, toss and continue roasting for 10-15 mins until golden brown and crispy.

Notes
I did not peel my potatoes. This is just a personal preference and won't affect the way the potatoes cook.
Cook times may very based on size; check on your potatoes about every 5 minutes after the first 15 minutes of roasting.
Serving tip: If you're serving these for a crowd and find that your sweet potatoes get mushy after you've transferred them to a serving bowl, try using a serving tray instead. That way they can spread out and stay crispy instead of steaming up from all the heat of them being on top of each other.
