Preheat oven to 425°F. Remove any giblets or neck pieces from the cavity of your chicken, then pat it dry all over with paper towels.
In a small saucepan, melt the butter then add the white cooking wine, lemon juice, garlic, rosemary, lemon zest, salt, and pepper.
Place the chicken in a dutch oven. Pour half of the mixture over it, rubbing it evenly over the skin.
Roast uncovered for 30 minutes, then lower the oven to 375 and baste with the remaining butter mixture.
Continue roasting for 1 hour, or until the internal temperature reaches 165°F in the thickest part of the thigh, basting with the juices in the dutch oven occasionally.
Remove from oven and let rest for 10–15 minutes before carving.
Spoon pan juices over the sliced chicken and serve warm.
