Instructions
Preparation Steps
Pat the chuck roast dry. In a small bowl, combine salt, pepper, garlic powder, onion powder, oregano, basil, and red pepper flakes. Rub the spice mix all over the roast.
Optional: Heat olive oil in a large skillet over medium-high heat. Sear the roast 3 to 4 minutes per side until deeply browned.
Place sliced onions and minced garlic in the bottom of the slow cooker. Set the roast on top.
Whisk together beef broth, Worcestershire sauce, Italian dressing mix, and pepperoncini brine. Pour over the roast. Scatter the pepperoncini peppers around the meat.
Cover and cook on Low for 8 to 9 hours (or High for 4 to 5 hours) until the beef is fork-tender.
Transfer the roast to a board and shred with two forks, discarding large pieces of fat. Skim excess fat from the cooking liquid.
Return shredded beef to the slow cooker and toss with the juices. Taste and adjust seasoning if needed.
Serve on toasted hoagie rolls with provolone and giardiniera. Spoon extra jus over the meat or serve on the side for dipping.
Notes
For Chicago-style flair, use hot or mild giardiniera and plenty of pepperoncini. Leftovers keep 4 days in the fridge or 3 months frozen; reheat gently with a splash of broth. If you prefer less heat, reduce or omit the red pepper flakes and use mild peppers.
