01 - Set oven to 425°F (220°C).
02 - Heat 1 tablespoon olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Pat chicken thighs dry and season with salt and pepper. Sear chicken skin-side down for 4–5 minutes until golden brown, then flip and cook for 2 minutes. Remove chicken to a plate.
03 - Toss sweet potato cubes with 1 tablespoon olive oil, smoked paprika, salt, and pepper. Spread evenly in the skillet.
04 - Nestle the seared chicken thighs on top of the sweet potatoes, skin-side up.
05 - In a small bowl, whisk together honey, soy sauce, minced garlic, apple cider vinegar, and chili flakes, if using.
06 - Drizzle the honey garlic sauce evenly over the chicken and sweet potatoes. Transfer skillet to the preheated oven. Roast uncovered for 25–30 minutes, or until chicken is cooked through (internal temperature 165°F/74°C) and sweet potatoes are tender.
07 - For crispier chicken skin, broil for 2–3 minutes at the end of the roasting time.
08 - Garnish with chopped parsley and serve with optional lemon wedges.
