01 - Set oven to 400°F and allow to fully preheat before cooking.
02 - Pat chicken thighs dry with paper towels. Season each piece evenly 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 smooth.
04 - Place chicken thighs in a single layer in a large oven-safe skillet or baking dish. Pour prepared glaze over chicken, ensuring each piece is thoroughly coated.
05 - Bake uncovered for 30 to 35 minutes, basting with pan juices every 10 to 15 minutes, until skin is deep golden and chicken reaches an internal temperature of 165°F.
06 - If desired, broil for 2 to 3 minutes until skin is extra crisp.
07 - Let chicken rest for 5 minutes before garnishing with chopped fresh parsley and serving.
