Mississippi pot roast slow-cooked with pepperoncini, ranch seasoning, and butter yields incredibly tender, flavorful beef. This high protein, family-favorite carnivore dish practically melts in your mouth.
Pat the beef chuck roast dry with paper towels and place it in the center of a large slow cooker.
Sprinkle the ranch seasoning mix and au jus gravy mix evenly over the surface of the roast for balanced flavor infusion.
Arrange the pepperoncini peppers over and around the meat, letting some peppers touch the roast directly to add tang.
Place half a cup of unsalted butter (one stick) on top of the roast; keep the butter whole for gradual basting.
Cover and slow-cook on LOW for 8–10 hours, or until the beef is fork-tender and easily shredable—avoid opening the lid during cooking for best moisture retention.
Once done, shred the beef in the pot using two forks, mixing well with all the juices and peppers before serving.
