Recipe Notes

Pressure cooking time for a beef roast is determined by thickness and not weight. As a general guideline, figure on 20 minutes for each inch of thickness. If you have a roast that is more than 3 inches thick, add another 10 or 15 minutes to the cooking time.

Remember, allow for a natural release when pressure cooking a roast and always let it set for at least 10 minutes (outside of the cooker) so that the meat fibers can reabsorb the juices.
