Using kitchen shears, remove the backbone of the chicken by cutting along both sides of the spine. Flatten the chicken by pressing down on the breastbone.
Place the chicken on a wire rack set on a baking sheet. Rub the chicken with olive oil, then season with salt, pepper, garlic powder, and paprika.
Roast the chicken in the preheated oven for 45 minutes, or until the internal temperature reaches 165°F (74°C).
Let the chicken rest for 10 minutes before carving and serving.
Notes:
For extra flavor, marinate the chicken in the fridge for a few hours before cooking.
