Add oil to pot and press saute. Once hot add diced bacon and cubed chicken. Cook until outside of chicken pieces are no longer pink. Then turn pot off.
Use a bit of your broth to deglaze the pot (scrape stuck on meat off of bottom of pot)
Sprinkle in ranch mix, broth and pasta on the top. Gently submerge orzo into liquid. Seal lid and pressure valve closed.
Set to high pressure for 5 minutes followed by a quick release.
Lift lid and cut block of softened (room temp.) cream cheese into small cubes. Add these into the hot soup. Stir until melted.
If necessary turn to saute and stir so it is all melted and creamy.
