A tender and flavorful slow cooker Mississippi chuck roast with pepperoncini peppers, ranch seasoning, and butter, perfect for cozy dinners and easy meal prep.

Ingredients

Scale
  • 3 to 4 pounds chuck roast (1.4 to 1.8 kg)
  • 1 packet ranch seasoning mix (about 1 ounce / 28 g)
  • 1 packet au jus gravy mix (about 1 ounce / 28 g)
  • 1/2 cup unsalted butter (115 g, 1 stick), softened or sliced into pats
  • 7 to 8 whole pepperoncini peppers, plus 1/4 cup (60 ml) pepperoncini juice
  • 1 teaspoon garlic powder (5 g)
  • Black pepper to taste
  • Optional: red pepper flakes for extra heat

Instructions

  1. Trim the roast by removing any excess fat or silver skin. Pat dry with paper towels.
  2. Sprinkle garlic powder and freshly ground black pepper all over the meat, rubbing gently.
  3. Place the roast in the center of a 6-quart slow cooker.
  4. Evenly distribute the ranch seasoning packet and au jus gravy mix over the roast.
  5. Place pats of unsalted butter on top of the seasoned roast.
  6. Arrange the whole pepperoncini peppers on and around the roast. Pour in the pepperoncini juice.
  7. Cover and cook on LOW for 6 to 8 hours until the roast is tender and falls apart easily.
  8. Check doneness after 6 hours by piercing with a fork; cook longer if needed.
  9. Shred the meat in the slow cooker using two forks, mixing with the sauce.
  10. If the sauce is too thin, cook uncovered on HIGH for 15-20 minutes to thicken.
  11. Serve warm over mashed potatoes, sandwich rolls, or roasted vegetables.

Notes

Do not use frozen roast; thaw fully before cooking. Avoid opening the slow cooker lid frequently to maintain heat. Butter sliced into pats melts evenly and enriches the sauce. Use fresh pepperoncini juice for best flavor. Adjust seasoning after cooking by adding red pepper flakes if desired. Leftovers taste better after a day and can be refrigerated for up to 4 days or frozen for up to 3 months.
