01 - Set the oven to 425°F to prepare for roasting.
02 - In a small bowl, combine coarse sea salt, black pepper, smoked paprika, garlic powder, dried thyme, ground cumin, cayenne pepper if using, and olive oil until a paste forms.
03 - Rub the spice paste thoroughly over the chicken, including beneath the skin and inside the cavity for maximum flavor.
04 - Place lemon quarters, smashed garlic cloves, and fresh herbs inside the chicken cavity.
05 - Tie the legs together with kitchen twine and tuck the wings underneath the body to ensure even cooking.
06 - Arrange the chicken breast-side up on a rack inside a roasting pan.
07 - Roast the chicken at 425°F for 20 minutes to develop a crispy skin.
08 - Lower the oven temperature to 350°F and roast for an additional 60 minutes, or until the internal temperature reaches 165°F in the thickest part of the thigh and juices run clear.
09 - Allow the chicken to rest for 10 to 15 minutes before carving to let juices redistribute.
