Your pot will take about 15 minutes to come to pressure. If you want to speed this up, you could sauté the onions and chicken for a few minutes before adding the other ingredients. For me, this cuts the preheat time in half or more, also you could reduce the cooking time as well. However, then you have to stir and watch the pot more than before. So, do whatever YOU feel like doing. Experiment! When it comes to such a quick cooking time, if something isn’t done enough to your liking, it’s easy to add a couple extra minutes!
