How long to cook a 1 pound roast beef?
If it’s frozen then 15 minutes per pound. However, in this case it may take 1/2 hour to 45 minutes. Put oven up to 400 for 15 minutes to sear roast, then turn down to 350. If in doubt use a knife and put a small cut in the thickest part of the roast. If you like medium rare it should be just pink inside. If you like it well done then cook a little longer and check in 15 minutes and if juices run clear it’s done.
