Clean out the giblets from inside the chicken and rinse out well.
Cut any excess fat or skin. I use a sharp kitchen shear.
Lay the chicken breast side down. Remove the spine by cutting along the sides of the spine. You may need to use a bit of strength to get it done. Please be careful. Toss the spine.
Clean the inside further and rinse chicken.
Place chicken skin side up and press down with force on the breast bone to flatten the chicken as much as possible.
Place chicken on an aluminum foil lined baking sheet with a wire rack over the foil.
Start with drizzling the oil over the chicken and follow with the rest of the spices, making sure they are evenly distributed over the chicken.
Roast chicken until thickest part of breast close to bone registers 150°F on an instant-read thermometer and joint between thighs and body registers at least 175°F, about 45 minutes, reducing heat to 450°F if chicken starts to darken too quickly.
