  • 2 tbsp vegetable oil
  • 3 to 5 lb Chuck roast, cut into 3 to 4 even chunks so to fit easier in the Instant Pot.
  • ¾ cup low sodium beef broth
  • ½ cup pepperoncini juice from the jar
  • 1 packet (1-ounce) Dry Ranch Seasoning Mix
  • 1 packet (1-ounce) Au Jus Gravy Mix
  • 10 whole pepperoncinis
  • 2 tbsp butter


  • Press “SAUTE” on the Instant Pot and heat up the vegetable oil.
  • Add meat to the hot oil and cook for 5 minutes.
  • Flip it over and continue to cook for 5 more minutes. Add more oil, if needed.
  • Remove meat from the Instant Pot and set aside.
  • Slowly add beef broth to the IP; stir to loosen up all the browned bits from the bottom of the pot.
  • Whisk in pepperoncini juice.
  • Transfer meat back into the IP.
  • Sprinkle ranch seasoning mix and the gravy mix over the meat.
  • Add pepperoncinis and butter.
  • Turn off the saute mode.
  • Close IP with the lid and set the steam release knob to Sealing position.
  • Press the Manual button (or pressure cook button) and set to 60 minutes HIGH PRESSURE.
  • When the cooking cycle ends, do a Natural Pressure Release for 15 minutes.
  • Turn off the pot and release remaining pressure by turning knob to the venting position.
  • When the pin drops, open the lid.
  • Remove pot roast from the IP; let rest 10 minutes before cutting.
  • Serve pot roast with juices. See recipe notes below*


  1. Optional: If you want to thicken the juices, in a small bowl whisk together 2 tablespoons cornstarch with ¼ cup cold water.
  2. Select the saute setting on the IP and bring juices to a boil.
  3. Whisk in the cornstarch mixture and cook for 2 minutes, stirring frequently, until slightly thickened.
  4. If mixture gets too thick, add more liquid (beef broth or water) to reach desired consistency.
