Remove the giblets from the hen’s cavity and save for making stock.
Spatchcock the bird by removing the backbone with kitchen shears. Save the bone for stock as well. Turn the hen over and flatten the breast bone with the heels of your hands until you hear a crack. Tuck the wing tips under the breasts.
In a glass baking dish, large enough to hold the flattened hen, mix together the lemon juice, EVOO, herbs, salt, and pepper.
Place the hen in the marinade and flip several times to coat the entire bird. Set this aside for an hour.
You want the game hen to be at room temperature prior to grilling. If you need more time, cover the dish with plastic wrap and place in the refrigerator. Take it out at least 30 minutes before you heat up the grill.
Preheat your GF contact grill to high.
Place the game hen, skin side up, on the grill and close the top. Grill for 10 minutes. Open the grill and flip the hen over. Grill for another 8 minutes, or until the internal temperature reads 170°F in the thigh.
Set the grilled hen on a cutting board to rest for at least 10 minutes. This is a good time to clean your grill.
Simply cut the hen in half through the breast bone and serve with side dishes. Side suggestions follow.
