Preheat oven to 400°F, place the oven rack in the lower ⅓ of the oven.
Rinse chicken inside and out, remove any pin feathers, and pat dry with paper towels. Bring chicken to room temperature.
Truss the chicken and drizzle with 1 tablespoon of Olive oil, using your hands to rub over the entire chicken. Season the chicken with 2 teaspoons of garlic powder, 2 teaspoons of kosher salt, and 2 teaspoons of fresh ground pepper, patting the seasoning in with your hands.
Spray an oven-safe pan with non-stick spray, place chicken with the breast side up in the pan. Roast the chicken for 75 to 90 minutes, or until the juices run clear. Check doneness with an instant-read thermometer placed in the thickest part of the thigh. It should read 165°F. Let the chicken rest for 15 minutes on a cutting board before slicing and serving.
