Roast beef hadn't been on the menu in quite a while when I spied a beautiful grass-fed, antibiotic-free sirloin roast at the meat counter of my local natural foods store. It weighed just 2.375 pounds (a little over a kilo) and was somewhere between 2 and 3 inches thick.
Since there are so many variables when cooking a roast, merely going by time, so many minutes per pound, doesn't really cut it. Though, of course, figuring an approximate time is important if you want to make sure the whole meal is ready at the same time!
Beef Roast Doneness
I took this roast's temperature after 55 minutes at the lower heat, looking for 145F/63C for medium-well. Checked it every 5 minutes after that, and after a couple of times it had hit my target temp.
Do you ever cook a small roast? I was surprised that this actually made 8 good servings as there was zero waste. Also, I'm always curious about the degree of doneness that people prefer.
