You will place the potatoes at the bottom of the pressure cooker. Then I use the trivet to place my chicken on it. If you do not have a trivet buy it. I use mine 90% of the time!
Then pour in your liquid which in this case is the chicken broth. You can use water or wine if you want. I would rather drink my wine but to each their own. You need 1 cup.
Then I put the onion soup mix on top. I then sneak the veggies in the pressure cooker around the side. This is the easy part.
Set the pressure cooker for 30 minutes on high pressure for a 5lb pound chicken.
Then with your mitts turn the dial to allow for a natural release. That means that you are letting out the steam until it is all out. I then check the temperature of my chicken to make sure it is cooked. I use this meat thermometer.
