Instructions

Step 1: Preheat your oven to 325°F. Pat dry a 4 lb whole heritage chicken with paper towels and rub all over with 3 tbsp olive oil, 2 tsp sea salt, and 1 tsp freshly ground black pepper.
Step 2: Stuff the cavity of the chicken with 8 smashed garlic cloves, 6 sprigs of fresh thyme, and 1 halved lemon to infuse aromatic flavors during roasting.
Step 3: Spread 2 tbsp softened butter evenly over the chicken skin to promote browning and moisture retention.
Step 4: Place the chicken breast-side up on a roasting rack inside a roasting pan and roast for about 2.5 to 3 hours, basting every 45 minutes with the pan juices, until an internal temperature of 165°F is reached and the skin is golden brown and crisp.
Step 5: Remove the chicken from the oven and let it rest for 15 minutes before carving to allow juices to redistribute for juicy meat.
