Ingredients

3 to 4 pounds beef chuck roast cut into large chunks
½ cup unsalted butter (one stick)
8-10 pepperoncini peppers with ¼ cup of the juice
1 ½ tablespoons au jus mix
1 ½ tablespoons ranch seasoning
½ cup beef broth
2 to 3 tablespoons olive oil
1 teaspoon kosher salt or to taste
½ teaspoon pepper

Instructions

Season the roast with salt and pepper on all sides and trim excess fat.
Set the Instant Pot to 'Sauté' mode and add olive oil. Once hot, sear the roast chunks on all sides until browned, about 3-4 minutes per side. Remove and set aside.
Add the beef broth to the Instant Pot, scraping the bottom to release any browned bits.
Place the roast back into the Instant Pot. Add the pepperoncini peppers, their juice, au jus mix, ranch seasoning, and the stick of butter on top of the roast.
Close the lid and set the Instant Pot to 'Pressure Cook' (Manual) on high for 60-80 minutes (or 20 minutes per pound of meat). Allow a natural release for 15 minutes, then quick release any remaining pressure.
Carefully remove the roast from the Instant Pot, shred with two forks, and mix with the juices before serving.
