Ingredients
- 3–4 pounds beef chuck roast
- 1 packet (1 ounce / 28 grams) ranch dressing mix
- 1 packet (0.9 ounces / 25 grams) au jus gravy mix
- 4 tablespoons (55 grams) unsalted butter
- 6–8 whole pepperoncini peppers with juice (about 100 grams)
- About 8 soft sandwich buns (brioche or potato rolls recommended)
- Optional: garlic powder or fresh garlic
- Optional: onion powder
- Optional: fresh parsley for garnish
Instructions
- Pat dry and trim excess fat from the beef chuck roast (3-4 pounds).
- Place the roast in the crockpot. Sprinkle ranch seasoning mix evenly over the top, then sprinkle the au jus gravy mix.
- Lay 4 tablespoons of unsalted butter on top of the roast.
- Scatter 6-8 pepperoncini peppers with some juice around and on top of the roast.
- Cover and cook on low for 7-8 hours or on high for 4-5 hours until the meat is fork-tender.
- Remove the roast and shred the meat using two forks or tongs. Return shredded meat to the crockpot and stir gently to soak up the juices.
- Slice and lightly toast the sandwich buns. Optionally brush the insides with melted butter or some au jus before toasting.
- Assemble sandwiches by piling shredded roast on toasted buns. Serve with a small bowl of au jus for dipping and garnish with fresh parsley if desired.
Notes
Do not lift the crockpot lid frequently during cooking to avoid extending cook time. If au jus is thin, thicken with a cornstarch slurry and cook on high for 15 minutes. Butter adds richness and improves mouthfeel. Use low and slow cooking for best tenderness. Adjust pepperoncini quantity to control heat. Leftovers keep well refrigerated for 3-4 days and freeze up to 2 months.
