Ingredients
- 3–4 lbs beef chuck roast
- 1 packet (about 1 oz) ranch seasoning mix
- 1 packet (about 0.87 oz) au jus gravy mix
- 1/2 cup (1 stick or 113 g) unsalted butter, sliced
- 7–10 pepperoncini peppers with juice (about 1/4 cup juice)
- 1 teaspoon garlic powder
- 1/2 teaspoon freshly ground black pepper
- Salt to taste
- Optional: chopped fresh parsley for garnish
Instructions
- Pat dry the beef chuck roast with paper towels. Optional: Sear the roast in a hot skillet with a bit of oil for 3-4 minutes per side until browned.
- Sprinkle salt, garlic powder, and black pepper evenly over all sides of the roast.
- Place the seasoned roast flat inside the slow cooker insert.
- Sprinkle ranch seasoning mix and au jus gravy mix evenly over the roast.
- Distribute sliced unsalted butter over the roast.
- Scatter pepperoncini peppers around and on top of the roast, then pour in about 1/4 cup of the pepperoncini juice.
- Cover and cook on LOW for 8 hours or on HIGH for 4-5 hours until the roast is fork-tender.
- Check doneness; if still tough, continue cooking in 30-minute increments.
- Remove roast with tongs and let rest for 10 minutes.
- Shred the roast using two forks, mixing in the juices and peppers from the slow cooker.
- Serve with sauce spooned over the shredded beef and garnish with chopped fresh parsley if desired.
Notes
Optional searing adds flavor but can be skipped for convenience. Do not rinse pepperoncini peppers to retain the tangy juice. Butter is key for a rich sauce but can be substituted with olive oil or plant-based spread for dairy-free option. Avoid lifting the slow cooker lid during cooking to maintain temperature. Rest the roast before shredding to keep juices locked in.
