Preheat oven to 425°F (220°C).
Pat chickens dry thoroughly — this ensures crisp skin.
Season generously inside and out with salt and pepper.
Rub butter or olive oil over skin.
Stuff cavities with garlic, lemon halves, and seasonal aromatics.
Place chickens breast-side up in roasting pan.
Roast about 60–75 minutes, or until internal temp reaches 165°F at thickest part.
Rest 10–15 minutes before carving.
This resting step keeps the meat juicy.
