A simple, comforting slow cooker recipe featuring tender, shredded beef chuck roast cooked with ranch seasoning, au jus mix, butter, and pepperoncini peppers, served on soft Hawaiian rolls.

Ingredients

Scale
  • 34 pounds beef chuck roast, well-marbled
  • 1 packet (about 1 oz) ranch seasoning mix (e.g., Hidden Valley)
  • 1 packet (approximately 0.87 oz) au jus gravy mix
  • 1/2 cup (1 stick) unsalted butter, sliced
  • 810 pepperoncini peppers with some juice
  • Salt and freshly ground black pepper to taste
  • 12 Hawaiian rolls or soft sandwich buns

Instructions

  1. Trim any excessive fat from the chuck roast and pat dry with paper towels. Season both sides lightly with salt and pepper.
  2. Place the roast in the slow cooker. Sprinkle the ranch seasoning evenly over the top, then add the au jus mix.
  3. Lay slices of unsalted butter on top of the roast. Scatter the pepperoncini peppers around and on top, pouring some of their juice in as well.
  4. Cover and cook on LOW for 8 hours without lifting the lid.
  5. After 8 hours, check tenderness by inserting a fork; if it doesn’t shred easily, cook for an additional 30 minutes to 1 hour.
  6. Use two forks to shred the meat directly in the crockpot, mixing gently with the juices and peppers.
  7. Slice Hawaiian rolls or buns in half and lightly toast if desired.
  8. Assemble sandwiches by piling shredded pot roast on each roll and spooning some buttery pepperoncini juices over the meat.
  9. Serve immediately while hot.

Notes

Do not lift the lid during cooking to maintain temperature and tenderness. Butter slices on top help baste the meat gradually. Save some pepperoncini peppers for garnish. If juices are too thin, thicken with cornstarch slurry and cook on high for 10 minutes before shredding. For gluten-free, substitute au jus mix with homemade beef broth thickened with cornstarch and serve on gluten-free buns or mashed potatoes. For dairy-free, use plant-based margarine or coconut oil instead of butter. To add spice, include sliced jalapeños or cayenne pepper.
