  • 34 pound chuck roast
  • 2 tablespoons ranch dressing mix
  • 2 tablespoons au jus mix
  • 68 pepperoncini
  • 1 cup water


  1. Saute setting sear chuck roast on both sides. Can do on stove.
  2. Add remaining ingredients to the pressure cooker. Set pressure to high and lid to sealing position.
  3. Cook for 25 minutes per pound.
  4. Allow pressure to release naturally for about 15 minutes before using the quick release valve.
  5. *use dairy free brands


If you’re making this recipe with a smaller roast, you will want to adjust the amount of seasoning you put in or you’ll end up with a super salty dish. For a 2 pound roast, use 1 tablespoon each of ranch and au jus mix.
