Preheat the oven to 425 degrees F (220 degrees C).
Place sweet potatoes into a large mixing bowl; drizzle with olive oil. Season with paprika, brown sugar, black pepper, onion powder, garlic powder, poultry seasoning, chili powder, and cayenne pepper; toss until potatoes are evenly coated. Spread onto a baking sheet.
Bake in the preheated oven for 15 minutes, then turn potatoes over with a spatula. Continue baking until potatoes are golden and tender, 10 to 15 minutes more.
