A simple and delicious slow cooker pot roast featuring tender chuck roast, tangy pepperoncini peppers, and savory ranch and au jus seasoning for a comforting, melt-in-your-mouth meal.

Ingredients

Scale
  • 3 to 4 pounds chuck roast
  • 1 packet ranch seasoning mix (about 1 ounce or 28 g)
  • 1 packet au jus gravy mix (about 1 ounce or 28 g)
  • 1/2 cup (1 stick or 113 g) unsalted butter, softened
  • 7 to 10 pepperoncini peppers with juice
  • 3 to 4 garlic cloves, minced or finely chopped
  • 1/2 teaspoon freshly ground black pepper
  • Optional: pinch of red pepper flakes
  • Optional: sliced onions

Instructions

  1. Pat the chuck roast dry with paper towels and trim any large fat caps if desired.
  2. Sprinkle freshly ground black pepper evenly over both sides of the roast.
  3. Optional: Heat 1 tablespoon of oil in a skillet over medium-high heat and brown the roast 2-3 minutes per side until golden crust forms.
  4. Place the roast in the slow cooker insert.
  5. Scatter the minced garlic evenly over the top of the roast.
  6. Sprinkle the ranch seasoning and au jus gravy mix evenly over the roast.
  7. Place the softened butter in chunks on top of the roast.
  8. Arrange the pepperoncini peppers around and on top of the roast, then pour in about 1/4 cup (60 ml) of their juice.
  9. Cover and cook on low for 8 hours or until the meat is fork-tender and shreds easily.
  10. After cooking, let the roast rest for 10 minutes, then shred the meat with two forks in the slow cooker, mixing it with the juices and peppers.
  11. Taste and add extra pepperoncini juice if more tang is desired.
  12. Serve over mashed potatoes, egg noodles, or crusty bread to soak up the sauce.
  13. If the sauce is too thin, remove the meat, turn the slow cooker to high, mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir into the liquid, and let thicken for 10-15 minutes before returning the meat.

Notes

Do not lift the slow cooker lid frequently to maintain temperature. Optional searing adds flavor but is not required. Use fresh garlic for best flavor. Adjust seasoning after cooking. To thicken sauce, use cornstarch slurry. Can be made in Instant Pot using sauté and pressure cook modes. Substitute brisket for chuck roast or banana peppers for pepperoncini. Use dairy-free butter or olive oil for dairy-free version. Add vegetables like carrots, potatoes, and onions for a complete meal.
