Follow these steps to make crispy, seasoned sweet potato wedges:

1. Preheat the Oven
   Preheat your oven to 425°F (220°C). This high temperature is crucial for achieving the perfect crispy texture.
2. Prepare the Sweet Potatoes
   Cut each sweet potato in half lengthwise, then slice each half into wedges. Aim for uniform thickness to ensure even cooking.
3. Season the Wedges
   In a large mixing bowl, combine the sweet potato wedges with olive oil, salt, pepper, garlic powder, smoked paprika, and ground cumin. Toss until the wedges are evenly coated with the seasoning mix.
4. Arrange on Baking Sheet
   Line a baking sheet with parchment paper or aluminum foil for easy cleanup. Arrange the seasoned wedges in a single layer on the sheet, making sure they are not overcrowded. This allows them to roast evenly and become crispy.
5. Roast the Wedges
   Place the baking sheet in the preheated oven and roast for about 25-30 minutes. Flip the wedges halfway through the cooking time to ensure they brown evenly on both sides.
6. Check for Doneness
   The wedges should be golden brown and crispy on the outside while remaining tender on the inside. If needed, roast for an additional 5 minutes to achieve the desired texture.
7. Garnish and Serve
   Remove the wedges from the oven and let them cool slightly. Garnish with chopped fresh parsley before serving for an added burst of flavor and color.
