The best and easiest way to cook frozen chicken breasts!
Place chicken breasts in the bottom of the Instant Pot (you can use the trivet if you want to but don't have to!) It's okay if their stacked, just make sure the chicken breasts aren't stuck together.
Pour water or chicken broth (liquid of your choice) over the chicken and season with salt and pepper (or seasonings of your choice).
Put the lid on and move the valve to sealing. Press Manual pressure and set the timer for 10-12 minutes (We've found 10 is just right, and 12 they are at 180 degrees F or more). The Instant Pot will take about 10 minutes to come to pressure and start counting down from 10.
When the cook time is up, let pressure release naturally for 5-10 minutes before releasing the remaining pressure. Check that the internal temperature of the chicken is 165 degree F.
Serve as is, chop, or add sauces as desired.
