  • 3 lb chuck roast
  • 4 cups beef broth
  • 1 pkg ranch seasoning mix
  • 1 pkg au jus seasoning mix
  • 5 whole pepperoncini's (also known as banana peppers)


  • Add broth, roast, ranch and au jus seasoning, and banana peppers to your Instant Pot. 
  • Cook on manual HIGH pressure for 100 minutes. Allow for a 30 minute NPR. 
  • Remove from the pot and roughly shred. 
  • Turn the Instant Pot onto Sauté, once boiling, thicken with corn starch slurry. I like to return the meat to the gravy, but that is just a personal preference.
  • Serve over Mashed Potatoes or rice.
  • Note: you can sear the outside of the roast prior to pressure cooking but this step is not necessary.
