Pat the roast dry. Mix the salt, pepper, garlic powder, rosemary, thyme, and olive oil, then rub it over every side of the beef. Set the roast on a rack and refrigerate uncovered for at least 8 hours or overnight.

Remove the roast from the refrigerator 1 1/2 to 2 hours before cooking. Place it bone-side down in a roasting pan and insert a probe thermometer into the thickest part of the meat.

Heat the oven to 250°F. Roast until the center reaches 118°F for medium rare or 125°F for medium, about 3 to 3 1/2 hours for a 5 to 6 pound roast.

Transfer the roast to a cutting board and tent loosely with foil. Rest for 30 to 45 minutes while the oven heats for the final sear.

Raise the oven to 500°F. Return the roast to the pan and roast for 6 to 10 minutes, until the exterior is deeply browned and sizzling.

Pour off excess fat from the pan, leaving the browned bits. Add beef broth, scrape the pan over medium heat, and simmer for 3 to 5 minutes. Season to taste.
