In a large bowl, combine garlic, olives, capers, prunes, olive oil, vinegar, oregano, salt, and pepper. Mix well until everything is coated. This marinade gives the dish its rich and bold flavor.

Place the chicken pieces into the marinade. Turn them well so each piece is covered. Cover the bowl and refrigerate for at least 4 hours. Overnight is even better for deeper flavor.

Preheat your oven to 375°F. While the oven heats, take the chicken out of the fridge. Let it sit for a few minutes. This helps it cook more evenly in the oven.

Transfer the chicken and all marinade into a baking dish. Spread everything evenly. Make sure the chicken skin faces up. This helps it turn golden and crispy while baking.

Sprinkle brown sugar over the chicken pieces. Then pour white wine around the dish. The sugar caramelizes while cooking, adding sweetness and a beautiful glaze.

Place the dish in the oven and bake for about 50 minutes. The chicken should be fully cooked and golden brown. The sauce will thicken and become rich.

Halfway through cooking, spoon some sauce over the chicken. This keeps it moist and flavorful. It also helps the top develop a glossy finish.

Make sure the chicken is cooked through. The juices should run clear. If needed, cook for a few more minutes until fully done and tender.

Remove from the oven and sprinkle fresh parsley on top. Let it rest for a few minutes. Serve warm with your favorite sides.
