1. Preheat Your Oven and Prepare the Baking Dish: Start by preheating your oven to 375 F (190 C). Lightly grease a 9×13 inch baking dish or line it with parchment paper for easier cleanup. This prevents the sauce from sticking and burning.

2. Season the Chicken Thighs: Pat the chicken thighs dry with paper towels. This helps the skin crisp up nicely. Place them in the prepared baking dish and season both sides generously with salt and black pepper.

3. Whisk Together the Flavorful Sauce: In a medium bowl, combine the whole berry cranberry sauce, orange juice, brown sugar, Dijon mustard, dried thyme, and garlic powder. Whisk everything together until the mixture is smooth and well combined.

4. Pour the Sauce Over the Chicken: Spoon or pour the cranberry orange sauce evenly over the chicken thighs in the baking dish. Make sure each piece of chicken is well coated with the sauce.

5. Bake Until Cooked Through: Place the baking dish in the preheated oven and bake for 35-40 minutes. The chicken is done when its internal temperature reaches 165 F (74 C) when measured with a meat thermometer inserted into the thickest part of the thigh, avoiding the bone. The skin should be golden brown and the sauce bubbly.

6. Rest and Garnish: Once cooked, remove the baking dish from the oven. Tent it loosely with aluminum foil and let the chicken rest for 5-10 minutes before serving. This allows the juices to redistribute, ensuring tender and moist chicken. If desired, sprinkle with fresh chopped parsley before serving for a pop of color and freshness.
