Put the chicken top of a trivet in your pot or on top of 2 halved potatoes to keep it off the bottom. Pour the broth into the pot as well. Close the lid and set the pressure cooker to 25 minutes (or about 6 minutes per lb). After the beep, leave the chicken inside the instant pot for another 15 minutes. Then gently release the pressure and remove. Put it in a preheated oven on the broil setting for a few minutes so it browns on top
