Start by preheating your oven to 400 degrees Fahrenheit. Lightly grease a large baking dish with olive oil or a non-stick cooking spray to ensure nothing sticks during the roasting process.
Pat the chicken breasts dry with paper towels. Season both sides generously with salt, black pepper, and garlic powder. Place them in a single layer in the prepared baking dish, ensuring they are not overlapping.
In a small mixing bowl, whisk together the honey, apple cider vinegar, olive oil, and dried rosemary. This mixture will act as both a marinade and a glaze, infusing the meat with a deep, herbal sweetness.
Scatter the fresh or frozen cranberries all around the chicken in the dish. Pour the honey mixture evenly over the top, making sure each piece of meat is well coated and the berries are glistening.
Place the dish in the center of the oven and bake for 25 to 30 minutes. The internal temperature of the meat should reach 165 degrees Fahrenheit. You will notice the cranberries beginning to pop and release their juices, mingling with the honey glaze.
Remove the dish from the oven and immediately sprinkle the crumbled feta cheese over the hot chicken. The heat will soften the cheese just enough. Let the dish rest for five minutes before garnishing with fresh parsley and serving.
