Set roast out, covered, for 2 hours to come to room temperature before roasting; cut away ties.
Preheat oven to 375°F; generously season your roast with salt, pepper and garlic powder on all meaty sides and ends.
Cut four deep slits in the meat and place a bay leaf in each slit; leave a bit of each leaf visible for easy removal before carving.
Place the roast, bone side down, on a roasting rack set in a baking pan; do not cover; do not add water.
Place roast in hot oven; after 1 hour, turn the oven off; DO NOT OPEN THE OVEN DOOR.
After at least 2 hours (longer is fine), reset oven to 375°F; DO NOT OPEN THE OVEN DOOR.
After 35 minutes, open the oven and remove roast.
Let roast rest ~10 minutes and remove bay leaves before carving; serve with warm au jus gravy.
