    large garlic cloves, mashed

  • 1

    teaspoon salt

  • ½

    teaspoon fresh ground black pepper

Take roast out of the refrigerator and let stand at room temperature for about 2 hours to take off the chill. Preheat oven to 350 degrees Fahrenheit. 2Mash together the garlic, salt, pepper, oregano, and rosemary; rub seasoning into the roast. Place meat, fat side up, on a rack in a shallow roasting pan. 3Place meat in the oven and roast approximately 45 minutes, until lightly browned. Open the oven and scatter the vegetables in the pan around the roast. Close the oven, then reduce temperature to 225 degrees. Bake approximately 2 1/2 hours for rare(140 degrees on a meat thermometer) or longer for more well done. 4When the meat is done to your satisfaction, take the roast out of the oven and place it on a carving board to rest for about 10 minutes before carving. 5Meanwhile, if enough juice has been rendered by the meat, prepare a natural gravy. Remove excess fat from the pan and place pan over low heat. Stir in suitable amount of water (1 to 2 cups) scraping to deglaze the bottom of the pan. Season with salt and pepper and a dash of Worcestershire sauce. Reduce gravy slightly, strain, and check seasonings. Serve warm with the roast beef.
