01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - Slice the sweet potatoes lengthwise into wedges about 0.6 to 0.8 inches thick.
03 - In a large mixing bowl, toss the sweet potato wedges with olive oil, smoked paprika, garlic powder, ground black pepper, kosher salt, and dried thyme until evenly coated.
04 - Place the wedges in a single layer on the prepared baking sheet, ensuring space between each piece for even roasting.
05 - Bake the wedges for 15 minutes, then carefully flip them over and continue baking for another 15 minutes, or until golden and crisp at the edges.
06 - Remove from the oven, sprinkle with fresh parsley and flaky sea salt if desired, and serve immediately.
