Preheat your oven to 425°F (220°C).
Clean the chicken and pat it dry with paper towels.
Rub the chicken all over with olive oil, garlic powder, onion powder, paprika, dried thyme, salt, and pepper.
Stuff the cavity with lemon halves, smashed garlic, and fresh herbs.
Place the chicken in a roasting pan breast-side up.
Roast for 1 hour and 15 minutes, or until the internal temperature reaches 165°F (74°C) in the thickest part of the thigh.
Let the chicken rest for 10-15 minutes before carving and serving.
