Set your oven to 400°F (200°C). This high heat ensures the chicken cooks quickly, sealing in moisture for a tender, juicy finish.
Lightly grease a 9×13-inch baking dish with butter or nonstick spray. This helps prevent sticking and makes cleanup a breeze.
In a medium bowl, whisk together the melted butter, minced garlic, lemon juice, chopped parsley, salt, and pepper. This fragrant mixture will coat the chicken and infuse it with flavor.
Pat the chicken breasts dry with paper towels — this step helps the garlic butter adhere better and promotes browning. Optionally, sprinkle a pinch more salt and pepper on both sides.
Place the chicken breasts in a single layer inside the prepared dish. Pour the garlic butter mixture evenly over the top, using a spoon or pastry brush to coat each piece thoroughly.
Transfer the dish to the oven and bake for 25–30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) when checked with a meat thermometer.
For golden, slightly crispy edges, switch your oven to the broil setting for the last 2–3 minutes. Keep a close eye to avoid burning.
Let the chicken rest for 5 minutes before slicing — this helps the juices redistribute. Garnish with extra fresh parsley and serve warm.
