Place the roast in a roasting pan. Cut a few shallow slits on the non-fatty side of the roast. In a small bowl, combine the rosemary, oregano, olive oil, and garlic. Rub this mixture on all sides of the roast, pressing it into the slits on the top. Allow the roast to sit and marinate in the refrigerator for 30 minutes to one hour.
Preheat the oven to 450ºF. Sprinkle the salt and pepper all over the roast, putting an extra thick layer on the fatty side. Turn the roast over so the fatty side is facing up, then place in the preheated oven for 25 minutes.
Turn the oven down to 325 degrees and continue to cook for 2 hrs or until the center registers 130 degrees for a medium-rare center. Tent the roast and let it rest for 20-30 minutes before slicing. Slice and serve with the horseradish sauce.
Horseradish Sauce
Mix together sour cream, horseradish, vinegar, and parsley. Season to taste with salt. Serve with the beef. The sauce and leftover roast beef make a great sandwich the next day!
Notes
Tip: Cook time is approximately 15- 20 mins per lb, so if your roast is smaller, just calculate the full cook time that way.
