Ingredients
  

  • For the Beef:
  • 3 –4 lb boneless chuck roast bottom round or rump roast also works
  • 1½ tsp kosher salt
  • 1 tsp black pepper freshly ground
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1½ tsp dried oregano
  • 1 tsp dried basil
  • ½ tsp dried thyme
  • ½ tsp crushed red pepper flakes adjust to taste
  • 1 tbsp olive oil for searing
  • For the Au Jus Braising Liquid:
  • 2 cups low-sodium beef broth high-quality recommended
  • 1 cup water
  • 1 tbsp Worcestershire sauce
  • 4 garlic cloves minced
  • ½ cup pepperoncini peppers sliced (from jar)
  • 3 tbsp pepperoncini brine liquid from the jar — secret flavor booster
  • For the Sandwich Assembly:
  • 8 Italian hoagie rolls or sturdy sub rolls Turano brand if available
  • 1 cup Chicago-style hot giardiniera drained (mild or hot)
  • 1 cup sautéed sweet green / Melrose peppers optional
  • 8 slices provolone cheese optional — purists may skip

Equipment

  • 6-qt Slow Cooker / Crockpot
  • Large Cast Iron Skillet
  • Sharp Carving Knife
  • Cutting board
  • Wooden Spoon / Tongs
  • Ladle (for au jus)
  • Meat Thermometer
  • Measuring Cups & Spoons
  • Baking Sheet (for toasting rolls)
  • Aluminum Foil

Method
 

  1. Season the Beef:
  2. In a small bowl, mix kosher salt, black pepper, garlic powder, onion powder, oregano, basil, thyme, and red pepper flakes. Pat the chuck roast completely dry with paper towels, then coat all sides generously with the spice blend.
  3. (Pro Tip: Season and refrigerate uncovered overnight for 24 hours for maximum flavor penetration.)
  4. Sear the Roast:
  5. Heat a cast iron skillet over medium-high heat until smoking hot. Add olive oil. Sear the roast 2–3 minutes per side until a deep brown crust forms on all surfaces. Do not move the beef during searing.
  6. Build the Au Jus:
  7. Deglaze the skillet with ¼ cup of beef broth, scraping up all browned bits. Pour into the slow cooker. Add remaining broth, water, Worcestershire sauce, minced garlic, pepperoncini peppers, and pepperoncini brine. Stir to combine.
  8. Slow Cook:
  9. Place the seared roast into the slow cooker. Cover and cook on LOW for 8–10 hours or HIGH for 4–5 hours, until the beef shreds easily with two forks.
  10. (Tip: LOW and slow is always better for maximum tenderness.)
  11. Shred & Soak:
  12. Remove roast to a cutting board and shred into long thin strips with two forks. Return shredded beef to the slow cooker, stir into the au jus, and cook on LOW for 1 additional hour so every strand absorbs full flavor.
  13. Toast the Rolls:
  14. Preheat oven to 350°F. Split hoagie rolls, place cut-side up on a baking sheet, and toast for 4–5 minutes until lightly golden. Toasted rolls hold up better against the au jus.
  15. Assemble & Serve:
  16. Pile shredded beef generously onto each toasted roll. Add provolone cheese if using. Top with hot giardiniera and/or sautéed sweet peppers. For authentic Chicago style — briefly dip the entire assembled sandwich into simmering au jus for 3–5 seconds. Serve with extra au jus on the side for dunking.
  17. (Chicago Style: "Wet" = extra jus ladled on. "Dipped" = whole sandwich dunked. "Dry" = minimal jus. "Sweet and Hot" = both peppers.)

Notes

Best Cut: Chuck roast is ideal for a slow cooker. Bottom round or rump roast works for oven-roasting and thin-slicing.
Make Ahead: Cook and shred beef up to 3 days ahead. Store submerged in au jus in the fridge — flavor improves overnight.
Freezing: Freeze beef + au jus together in airtight bags for up to 3 months. Thaw overnight, reheat gently on LOW.
Oven Method: Roast at 300°F in a covered Dutch oven for 3–3.5 hours until internal temp reaches 200–205°F. Refrigerate overnight before slicing paper-thin against the grain.
Instant Pot Method: Sear on Sauté mode, pressure cook on HIGH for 65 minutes + 15-min natural release.
Giardiniera: Hot giardiniera is traditional Chicago style. Never skip it — it defines the sandwich.
Bread: Look for Turano Italian rolls or any sturdy hoagie bun. Always toast lightly before loading.
Cheese: Provolone is classic. Mozzarella or fontina also works. Chicago purists often skip cheese entirely.
