Step 1: Prepare the Hens

1. Preheat your oven to 400°F (200°C).
2. Rinse the Cornish hens under cold water and pat them dry with paper towels. Remove any giblets from the cavity.
3. Generously season the inside and outside of each hen with salt and pepper.

Step 2: Prepare the Garlic and Rosemary Mixture

1. In a small bowl, combine the olive oil, minced garlic, and chopped rosemary. Mix well to create a paste.

Step 3: Stuff and Coat the Hens

1. Place half a lemon inside the cavity of each hen.
2. Rub the garlic and rosemary mixture all over the outside of the hens, ensuring even coverage.

Step 4: Roast the Hens

1. Place the hens breast side up in a roasting pan. Pour the chicken broth into the bottom of the pan to keep the hens moist during cooking.
2. Roast in the preheated oven for about 50–60 minutes, or until the internal temperature reaches 165°F (74°C) and the juices run clear when pierced. Baste the hens with the pan juices halfway through cooking for extra flavor.

Step 5: Rest and Serve

1. Once cooked, remove the hens from the oven and let them rest for about 10 minutes before carving.
2. Serve the Cornish hens on a platter, garnished with fresh rosemary sprigs and lemon wedges. Drizzle with pan juices for added flavor.
