The time it takes for the ribs to cook will be dependent on the recipe and the tenderness of the meat that you are trying to achieve. Once you have locked the lid in place and the pot has come to a high-pressure point, the meat will start cooking. If you are using a stovetop pressure cooker, it will take about 20 minutes for the meat to get tender, but if you want the meat to be cooked thoroughly, 30 minutes should be enough to achieve that goal.
