01 - Preheat oven to 400°F (200°C).
02 - Pat chicken thighs dry with paper towels and season both sides with salt and black pepper.
03 - In a mixing bowl, whisk together maple syrup, Dijon mustard, gluten-free soy sauce, minced garlic, apple cider vinegar, and smoked paprika until fully blended.
04 - Place chicken thighs in a single layer in a large oven-safe skillet or baking dish. Pour the glaze evenly over the chicken, turning each thigh to ensure thorough coating.
05 - Bake uncovered for 30 to 35 minutes, basting with pan juices every 10 to 15 minutes, until chicken is golden brown and internal temperature reaches 165°F (74°C).
06 - If desired, broil for an additional 2 to 3 minutes to achieve crispier skin.
07 - Allow chicken to rest for 5 minutes before garnishing with chopped fresh parsley and serving hot.
