This easy cooking method allows you to cook PERFECTLY tender boneless beef roasts (from rare to medium-well) of almost any size, as long as the roast is at least 2-1/2 to 3-inches thick. I've used this method for 30+ years, and find it's a lifesaver when I'm having company and want a foolproof entree without the fuss! For Sunday dinners - cook the roast before church, turn the oven off, and dinner is ready when you return home. Great meat for party and wedding meat trays. If you enjoy this cooking method, you might want to try my pork loin/tenderloin version - Recipe #63828. You'll be glad you did!
