Directions

1. Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C).
2. Mix garlic powder, seasoned salt, onion powder, dried oregano, salt, and pepper in a small bowl; set aside.
3. Pour 1/3 of one can of beer into the bottom of a 9x13-inch baking dish. Place the open beer can in the center of the baking dish.
4. Rinse chicken under cold running water. Discard giblets and neck from chicken; drain and pat dry. Fit whole chicken over the open beer can with the legs on the bottom.
5. With the chicken breasts facing you, use a paring knife to cut a small slit on each side. Press the tip of each wing into the slit to encourage even cooking.
6. Rub the reserved seasoning mixture to taste over entire chicken.
7. Pat green onion slices evenly onto the chicken; it's okay if some fall off. Press green onion halves into the top cavity of the chicken. Open the second beer can and pour 1/2 of it into the pan; set the remaining beer aside to use during baking.
8. Bake chicken in the preheated oven for 45 minutes. Pour the remaining beer into the pan under the chicken and continue baking until no longer pink at the bone and the juices run clear, about 30 additional minutes. An instant-read thermometer inserted into the thickest part of the thigh, near the bone should read 180 degrees F (82 degrees C).
9. Remove from the oven and discard the beer can. Cover chicken with a doubled sheet of aluminum foil.
10. Let rest in a warm area for 10 minutes before slicing.
