how long to cook 2 lb roast in oven?
 Bake the 2lb roast for 12 minutes in the preheated oven, then reduce heat (without opening the oven door) to 275 degrees and continue roasting for about 60+ minutes or until the thermometer reads 135-140 degrees (for medium rare). Remove from oven and let rest for at least 10 minutes before slicing.
