01 - Preheat the oven to 450°F. Pat the chicken dry thoroughly with paper towels, including the cavity, to ensure maximum skin crispiness.
02 - In a small bowl, blend kosher salt, black pepper, paprika, garlic powder, and onion powder.
03 - Rub the chicken evenly with olive oil and melted butter. Generously coat with the seasoning mixture, making sure to work some under the skin where possible.
04 - Fill the chicken cavity with lemon halves, smashed garlic cloves, fresh thyme, and rosemary sprigs.
05 - Tie the legs together using kitchen twine and tuck the wing tips underneath the bird.
06 - Place the chicken breast-side up on a wire rack positioned over a roasting pan or baking sheet.
07 - Roast for 50 to 60 minutes, until the skin is golden brown and juices run clear when the thigh is pierced. Confirm internal temperature reaches 165°F.
08 - Allow the chicken to rest for 10 to 15 minutes to let juices redistribute before carving.
