In a small bowl, mix the minced garlic, lemon juice, olive oil, thyme, rosemary, salt, and pepper to create a marinade.
Pat the whole chicken dry with paper towels. Gently lift the skin over the breast and thighs, being careful not to tear it, and rub some of the marinade directly onto the meat. Spread the remaining marinade over the outside of the chicken.
Place the quartered onion and lemon slices inside the cavity of the chicken to infuse flavor while roasting.
If desired, add the chicken broth or water to the bottom of the roasting pan for additional moisture during cooking.
Place the chicken in a roasting pan breast side up, and tuck the wing tips under the body to prevent burning.
Roast the chicken in the preheated oven for approximately 1 hour and 15 minutes, or until the skin is golden and crispy, and juices run clear when pierced at the thighs. An internal temperature of 165°F (75°C) should be reached.
Remove the chicken from the oven and allow it to rest for 15 minutes before carving. This helps retain the juices.
Garnish with fresh parsley before serving.
Notes
Serve the chicken on a large platter surrounded by roasted vegetables and drizzle some pan juices over the top for a beautiful display.
