Preheat the oven to 425°F. Line a baking sheet with foil and lightly spray it with cooking spray.
Toss the sweet potato wedges in olive oil and herbs. Season the wedges with the salt and pepper and lightly toss again.
Place the wedges on the baking sheet with one of the non-skin sides down on the sheet. Roast the potatoes for 20-25 minutes. Remove them from the oven and carefully turn each wedge over so the skin side is facing down. Return them to the oven and let them roast for another 10 minutes before serving.
Notes
You can use other dried herbs or seasoning mixes to change up the flavors.
