Preheat the oven to 450 degrees. Line a roasting pan with foil (for easier cleanup) then place the roasting tray into the center of the pan.
Season the inside of the cavity with sea salt, freshly cracked pepper, and garlic powder, to taste (after removing any innards), then place the garlic cloves, onion slices, lemon, and clementine halves, into the cavity along with the sprigs of herbs.
Combine the olive oil, chopped oregano, sage, and thyme in a small bowl; mix until well combined.
Rub the herb mixture over the entire bird evenly; season with sea salt, freshly cracked pepper, and garlic powder, to taste.
Place a meat thermometer in the thigh of the chicken, making sure not to touch the bone.
Place into the oven and roast until the meat thermometer reads 165 degrees, about 60-75 minutes.
Remove from the oven and let the bird rest for 10-15 minutes before slicing and serving. Enjoy.
