Ingredients

  • 3 lbs chuck roast
  • 1 packet (1 oz) ranch dressing mix
  • 1 packet (1 oz) au jus gravy mix
  • 5 pepperoncini peppers (whole)
  • 1 cup low-sodium beef broth
  • 2 cups mixed vegetables (like carrots and potatoes)
  • 1 tablespoon oil (for searing)

Instructions

  1. Trim excess fat from the chuck roast and pat dry.
  2. Set the Instant Pot to “Sauté” mode, add oil, and sear the roast on all sides until browned.
  3. Sprinkle ranch dressing mix and au jus gravy mix evenly over the roast. Add pepperoncini peppers and pour in the beef broth.
  4. Add mixed vegetables around the roast.
  5. Secure the lid, set the valve to sealing, and cook on “Manual” (High Pressure) for 60 minutes.
  6. Allow pressure to release naturally for 15 minutes, then carefully quick release any remaining pressure.
  7. Remove the roast, shred with forks, and serve with the cooking liquid and vegetables or over mashed potatoes.

Notes

  • For extra flavor, add 1–2 tablespoons of pepperoncini juice to the broth.
  • If vegetables become too soft, cook them separately and serve alongside.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • This roast freezes well for up to 3 months.
