The Ultimate Crockpot Mississippi Roast is incredibly tender and juicy. After only 10 minutes of preparation in the morning, the roast simmers all day in a delicious sauce in the slow cooker. The addition of some veggies to the crockpot will result in the ideal weekday meal with a delectable gravy.


  • 34 pound chuck roast
  • 3/4 packet au jus mix 3/4 oz (You can add the whole packet if you’d like to have a more salty flavor.)
  • 1 packet ranch mix 1 oz
  • 1/4 cup unsalted butter (1/2 stick) Make sure to use unsalted butter, otherwise your roast can be too salty.
  • 10 pepperoncini peppers
  • optional vegetables such as potatoes and carrots


  • Into a 6-quart slow cooker, add the roast.
  • Around the roast, add the au jus mixture, ranch mixture, butter, and peppers. (If cooking the roast with additional veggies, put those first, then arrange the beef on top.)
  • the slow cooker’s lid. Cook the beef until it is soft and falling apart, about 8 hours on low or 4-5 hours on high.
  • With two forks, shred the roast after removing the cover.
  • (Optional) To make the gravy thicker: In a small bowl, combine 1 tablespoon cornstarch with 2 tablespoons water. After that, add the cornstarch/water combination to a small saucepan along with the remaining liquid. The gravy needs to be cooked for a few minutes until it thickens.
  • Add optional minced parsley as a garnish and gravy as a drizzle.


  • In the fridge, leftover roast can be stored for up to 4 days. Reheating in a skillet for 10 minutes or until well heated through is recommended.
  • Remaining roast can be frozen and kept in a freezer-safe container. They can endure for up to two months.
