Preheat your oven to 425°F (220°C).
Remove the chicken giblets. Rinse the chicken inside and out, then pat dry with paper towels.
Rub the chicken all over with the oil or butter, then season generously with salt and pepper.
Stuff the cavity with the lemon, herbs, and garlic.
Place the chicken in a roasting pan or on a baking sheet.
Roast the chicken in the preheated oven for about 1.5 hours, or until the juices run clear when you cut between a leg and thigh. The internal temperature should reach 165°F (74°C) when measured at the thickest part of the thigh, not touching bone.
Remove the chicken from the oven and let it rest for about 15 minutes before carving. This allows the juices to redistribute throughout the chicken, resulting in a moister bird.
