Step 1: Preheat and Prepare Ingredients : Preheat oven to 425°F (220°C). Pat chicken dry with paper towels for crispier skin. Cut sweet potatoes into uniform wedges for even roasting.
Step 2: Season Chicken and Sweet Potatoes : In a large bowl, toss sweet potato wedges with 2 tablespoons olive oil, garlic powder, smoked paprika, salt, and pepper. Rub chicken with 1 tablespoon olive oil, thyme, minced garlic (if using), salt, and pepper.
Step 3: Arrange on Baking Sheet : Place chicken thighs on a baking sheet, skin-side up. Arrange sweet potato wedges around the chicken in a single layer. Optional: Drizzle honey or maple syrup over sweet potatoes for extra caramelization.
Step 4: Roast in the Oven : Roast for 45–50 minutes, flipping sweet potatoes halfway through, until chicken reaches an internal temperature of 165°F (74°C) and skin is golden and crispy. Sweet potatoes should be tender inside and slightly caramelized on the edges.
Step 5: Garnish and Serve : Remove from oven and let chicken rest for 5 minutes. Sprinkle with fresh parsley or rosemary before serving.
