ROAST beef steamed in the pot is a different experience. The meat has a delightful texture you can't find in beef cooked any other way.
But one word of caution: It's going to take much less time to cook than you think. Rely strictly on your meat thermometer. The size of both the pot and roast will make a difference. If you like your beef rare, check the thermometer after 40 minutes. You can omit the vegetables if you don't want a complete dinner.
