DIRECTIONS:

Remove and discard the neck, giblets and any excess fat from the chicken. Rinse the chicken inside and out under cold water and pat dry with paper towels. Put onion and garlic in body cavity.

Open the beer can and pour off half of the beer. Set the half-full can on a flat surface and slide the chicken over the top so the can fits inside the cavity. Transfer the bird to the grill, keeping the can upright. Carefully balance the bird on its two legs and the can. Grill over Indirect Medium heat until the juices run clear and the internal temperature reaches 170 degrees F. in the breast and 180 degrees F. in the thickest part of the thigh, 1-1/4 to 1-1/2 hours. Wearing barbecue mitts, carefully remove the chicken and the can from the grill, being careful not to spill the beer--it will be hot. Let the chicken rest for about 10 minutes before lifting it from the can. Discard the beer. Cut the chicken into serving pieces. Serve warm.
