I have read a lot of answers,but not one answered if your roast was in a roasting bag ?For any beef with 2lbs of carrots,2lbs of cut potatoes the recipe is 18 to 22minutes per pound of roast with everything in the bag at 375 degrees!If you have a 2 lb roast with a lb of carrots,lb of potatoes 1 hr and 30 minutes!3lb of roast 1hr to 2 hrs depending on your oven?Thats allif the internal temp is over 180 your good to live another day,and the kids are ok!
