Add the seasonings to a small bowl. Combine all of the spices using a fork, then add the olive oil to the seasoning mix to make a paste.
Rinse the chicken leg quarters in cold water. Trim off any excess fat or skin from the quarters without breaking the skin.
Rub the chicken quarters on both sides with the seasoning paste, making sure to get the entire quarter covered with the seasonings.
Bake the chicken leg quarters at 400°F for 40- 45 minutes (cooking time can vary), or until the internal temperature of the meat is 165°F.
Remove the sheet pan from the oven and allow the baked chicken to rest for 5 minutes before serving.
