In a small bowl, combine the olive oil, minced garlic, rosemary, thyme, sage, lemon zest, salt, and pepper. Mix well to create a herb paste.
Pat the Cornish hens dry with paper towels. Place them on a roasting pan. Gently loosen the skin over the breast area and rub half of the herb mixture directly onto the meat under the skin. Rub the remaining mixture all over the outer skin of the hens.
In a large bowl, combine the baby carrots, Brussels sprouts, butternut squash, and red onion. Drizzle with olive oil, balsamic vinegar, salt, and pepper. Toss well to coat.
Spread the seasoned vegetables around the hens in the roasting pan. Pour in the chicken broth.
Place the pan in the preheated oven and roast for 55 minutes or until the hens reach an internal temperature of 165°F (75°C). Baste the hens with the pan juices halfway through the cooking time for extra flavor and moisture.
Once cooked, remove the hens from the oven and let them rest for 10 minutes. Garnish with fresh parsley before serving. Plate the hens alongside the roasted autumn vegetables.
Serve warm and enjoy the vibrant flavors of autumn!
Notes
Baste the hens halfway through cooking for added flavor.
