For a juicy and flavorful Roasted Chicken with Herb Butter, follow this recipe:

3. **Season the Chicken**: Gently lift the skin of the chicken from the breasts and legs. Spread half of the herb butter under the skin, directly on the meat. Rub the remaining butter over the outside of the chicken.

4. **Stuff the Chicken**: Place the lemon halves, onion quarters, and extra sprigs of thyme or rosemary inside the cavity of the chicken.

5. **Roast the Chicken**: Preheat your oven to 425°F (220°C). Place the chicken on a roasting rack in a roasting pan or on a baking sheet. Drizzle with olive oil if desired. Roast for 1 hour 15 minutes to 1 hour 30 minutes, or until the internal temperature reaches 165°F (75°C) in the thickest part of the thigh.

6. **Rest and Serve**: Let the chicken rest for 10 minutes before carving. This allows the juices to redistribute, ensuring a moist, tender chicken.

Serve this herb butter roasted chicken with roasted vegetables or mashed potatoes for a hearty, comforting meal. Enjoy!
