Tender, juicy beef slow-cooked with Italian seasonings, peppers, and onions, then piled high on crusty rolls with melty provolone cheese. This easy slow cooker dinner is perfect for game days, potlucks, or cozy family meals.

Ingredients

Scale
  • 34 lbs chuck roast or top round roast (boneless, well-marbled)
  • 2 cups low-sodium beef broth
  • 1 packet (about 1 oz) dry Italian dressing mix
  • 1 tablespoon dried Italian seasoning
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon kosher salt (adjust to taste)
  • 1/2 teaspoon black pepper
  • 1/2 cup pepperoncini pepper brine (from the jar)
  • 1/4 cup sliced pepperoncini peppers
  • 1 large yellow onion, thinly sliced
  • 2 bell peppers, thinly sliced (red and green recommended)
  • 34 cloves garlic, peeled and smashed
  • 68 sturdy hoagie rolls or Italian sandwich buns
  • Provolone cheese slices (or mozzarella)
  • Optional: extra pepperoncini, giardiniera, or roasted red peppers for topping

Instructions

  1. Pat the roast dry with paper towels and trim excess fat. Season all sides with salt and pepper.
  2. Place sliced onions and bell peppers in the bottom of the slow cooker. Scatter smashed garlic cloves on top.
  3. Lay the seasoned roast over the vegetables.
  4. In a bowl, whisk together beef broth, Italian dressing mix, Italian seasoning, garlic powder, onion powder, and pepperoncini brine. Pour over the roast. Top with sliced pepperoncini peppers.
  5. Cover and cook on LOW for 8-10 hours or HIGH for 4-5 hours, until beef is fork-tender and shreds easily.
  6. Remove beef from the slow cooker and shred with two forks, discarding large pieces of fat.
  7. Stir onions and peppers into the cooking juices. For a thicker sauce, simmer juices on the stove for 10 minutes or use as-is.
  8. Return shredded beef to the slow cooker and stir to coat with peppers, onions, and juices. Let sit on WARM for 15-30 minutes to absorb flavors.
  9. Slice and lightly toast hoagie rolls if desired. Pile with shredded beef, peppers, and onions. Top with provolone cheese and extra pepperoncini if desired.
  10. For melty cheese, broil assembled sandwiches for 1-2 minutes until cheese is bubbly.

Notes

For extra flavor, sear the roast before slow cooking. Use gluten-free rolls and dressing mix for gluten-free diets. For spicier sandwiches, add jalapeños or hot giardiniera. The beef and peppers freeze well for meal prep. Let beef rest in juices after shredding for best flavor. Broil sandwiches for melty cheese.
