Ingredients

Main Ingredients

  • 1 3-4 lb. chuck roast
  • 1 ounce ranch seasoning mix
  • 1 ounce au jus gravy mix
  • 6 pepperoncini peppers (plus a splash of the juice)
  • 1/2 cup butter
  • 2 tbsp oil (for searing)

Instructions

  1. Heat oil: In a large skillet, heat the 2 tablespoons of oil over medium-high heat until hot and shimmering.
  2. Sear the roast: Add the chuck roast to the skillet and sear each side for 3-4 minutes to develop a rich, browned crust that locks in flavor.
  3. Transfer to crock pot: Place the seared chuck roast into the crock pot, ensuring it sits flat.
  4. Add seasonings: Sprinkle the ranch seasoning mix and au jus gravy mix evenly over the top of the chuck roast.
  5. Add peppers and juice: Place the 6 pepperoncini peppers around and on top of the roast, adding a splash of the juice from the pepperoncini jar to contribute tanginess.
  6. Top with butter: Slice the 1/2 cup of butter into 1/2 inch pieces and evenly distribute them on top of the roast.
  7. Slow cook: Cover and cook on low in the crock pot for 8-9 hours, until the roast is tender and starting to pull apart easily.
  8. Shred the beef: Remove the peppers, then shred the beef using two forks.
  9. Return peppers: Return the pepperoncini peppers to the pot with the shredded roast if you prefer to keep them in the dish.
  10. Serve: Serve the Mississippi pot roast over mashed potatoes or rice for a delicious and comforting meal.

Notes

  • For more flavor, searing the roast is essential before slow cooking.
  • If you prefer a spicier dish, add extra pepperoncini peppers or some of the pepperoncini juice.
  • Leftovers refrigerate well and can be used for sandwiches or tacos.
  • Use a 4 to 6-quart crock pot for best results depending on the size of your roast.
  • Cooking times may vary slightly depending on your slow cooker model.
