How long to cook a 2 pound roast beef dutch oven?

To cook a 2-pound roast beef in a Dutch oven, preheat your oven to 325°F (163°C). Sear the roast on all sides on the stovetop, then add your desired vegetables and liquid. Cover and cook in the oven for about 2 to 2.5 hours, or until the internal temperature reaches 135°F (57°C) for medium-rare. Let it rest for at least 10-15 minutes before slicing to retain juices.
