In a small mixing bowl, make paste with melted butter and seasonings.
Next, rub that paste all over the chicken outside and inside the cavity.
Pour the water into the Instant Pot insert, set the trivet in the bottom of the insert, and place the whole chicken on top of the trivet.
Close and seal the Instant Pot, and select the manual setting and High Pressure. Set timer for 25 minutes.
Allow for a natural pressure release (NPR), which will take about 10-15 minutes.
Use your meat thermometer to check the internal temperature of your whole chicken. Your chicken is done when the temperature reaches 165 degrees F / 74 degrees C.
Once the chicken is safely cooked, let it rest for 10 minutes before slicing and serving.
