Preheat the oven to 375°F (190°C) or 400°F (200°C) for a crispier finish. Pat the chicken dry with paper towels to ensure crispy skin.
In a small bowl, mix salt, pepper, paprika, garlic powder, onion powder, thyme, rosemary, and cayenne pepper, then rub olive oil or butter all over the chicken, including under the skin, being careful not to tear it.
Generously season the chicken inside and out, then stuff the cavity with lemon halves, smashed garlic cloves, and any fresh herbs.
Place the chicken breast-side up on a roasting rack in a pan (or on a bed of chopped onions, carrots, and celery if a rack is unavailable).
Roast for 1 hour and 15–30 minutes, basting with pan juices every 20–30 minutes, until the internal temperature reaches 165°F (74°C) in the thickest part of the breast and 175°F (80°C) in the thigh.
Let the chicken rest for 15 minutes before carving. Enjoy weekly!
