Ingredients Method

Ingredients
  

  • 3.7 lb beef chuck roast a larger 5 lb roast can help reduce saltiness
  • 1 oz packet au jus gravy mix
  • 1 oz packet ranch seasoning mix
  • 4 tablespoons ¼ cup / ½ stick butter
  • 8 –10 whole pepperoncini peppers
Optional but used here:
  • ¼ cup pepperoncini juice brine — increases saltiness; omit for a milder result
  • Fresh parsley for garnish

Method
 

  1. Place the beef chuck roast directly into the bottom of the slow cooker. Set the butter on top of the roast in one piece or a few chunks so it melts evenly during cooking.
  2. Sprinkle the ranch seasoning mix evenly over the top of the meat. Follow with the au jus gravy mix, distributing it across the surface so the seasoning coats the roast as it cooks.
  3. Scatter 8–10 whole pepperoncini peppers over and around the roast. Pour in ¼ cup of the pepperoncini juice if using. For a less salty roast, skip the juice and use only the peppers.
  4. Cover with the lid and cook on HIGH for 5 hours, or until the roast becomes very tender and easily pulls apart. Avoid stirring during the first several hours so the seasoning stays on the meat.
  5. Around the 3-hour mark, open the lid briefly to flip or turn the roast so everything stays coated in the juices, then cover again and continue cooking. This step is optional.
  6. Once the roast is fork-tender, break the meat into large chunks directly in the slow cooker. Skim off excess rendered fat that collects on the surface while leaving the flavorful gravy behind.
  7. Sprinkle with fresh parsley if desired. Serve hot with the cooking juices spooned over the meat. Mashed potatoes pair especially well and soak up the gravy.
