Notes

Oven Method:
  • Preheat the oven to 225 degrees.
  • Heat oil in a 6 quart dutch oven over medium-high heat. Sear roast for 2-3 minutes per side. Remove from heat.
  • Sprinkle Au Jus and Ranch Dressing Mix over the roast. Top with cubed butter and pepperoncini peppers.
  • Bake, covered, for 7-8 hours.
  • For a quicker turnaround time: Wrap the roast in foil and place it in the Dutch oven with the lid on. Bake at 350 degrees for 3-4 hours.
  • Transfer the juices to a saucepan and proceed to gravy instructions.

Instant Pot
  • Turn the Instant Pot to Sauté Mode.
  • Brown the roast in olive oil for 5 minutes on each side, remove and set aside.
  • Deglaze the pan with 1 cup of low sodium beef broth or water. Run a silicone spatula along the bottom to release any brown bits.
  • Add the Roast back and sprinkle with the Au Jus and Ranch Dressing Mix. Top with cubed butter and pepperoncini peppers.
  • Set to Meat Mode and cook for 45 minutes. (Ensure the pressure valve is closed.)
  • Let the pressure release naturally for 5-10 minutes, then flip the quick release valve.
  • Remove the roast and cover it with foil to keep it warm.
  • Set the Instant Pot to Sautee mode and make gravy as noted in recipe instructions.
