Chicago Italian beef sandwich with thinly sliced roast beef, giardiniera, and au jus

The Chicago Italian beef sandwich is a beloved local specialty known for its tender, thinly sliced roast beef simmered in a flavorful broth and served on a crusty Italian roll. This recipe offers a restaurant-inspired home adaptation based on published methods, including Serious Eats’ approach, emphasizing USDA guidelines for cooking whole-muscle roasts to 145°F plus resting. The beef is cooked with aromatic seasonings and broth to create a rich gravy that keeps the meat moist and flavorful. Served wet or dipped, the sandwich is traditionally topped with spicy giardiniera or sweet peppers, adding a perfect balance of heat and tang. While this recipe draws from classic Chicago-style techniques, it is not an official recipe from any specific restaurant such as Al’s.

Ingredients

Beef and Broth

  • 3 lb (1.36 kg) beef top sirloin or eye of round roast, trimmed
  • 4 cups (960 ml) beef broth, low sodium
  • 1 cup (240 ml) water

Seasonings

  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme
  • 1 teaspoon crushed red pepper flakes (optional for mild heat)
  • 1 teaspoon black pepper
  • 1 teaspoon salt

Assembly

  • 4 Italian rolls (about 6 inches each), split
  • 1 cup giardiniera (Italian pickled vegetable mix) or sweet roasted peppers

Instructions

  1. Preheat oven to 325°F (163°C).
  2. In a roasting pan or Dutch oven, combine beef broth, water, garlic powder, onion powder, oregano, thyme, crushed red pepper flakes, black pepper, and salt. Stir to mix.
  3. Place the beef roast in the liquid mixture, fat side up. Cover tightly with a lid or foil.
  4. Roast in the oven until the internal temperature reaches 145°F (63°C) for medium-rare, about 1.5 to 2 hours depending on roast size. Use a meat thermometer for accuracy.
  5. Remove roast from oven and let rest covered for 15 minutes to allow juices to redistribute.
  6. Transfer the roast to a cutting board and thinly slice against the grain as thin as possible, ideally with a sharp knife or meat slicer.
  7. Strain the cooking liquid and keep warm; this will be your au jus for dipping or wetting the sandwich.
  8. To assemble, pile sliced beef onto the Italian rolls. Optionally dip or ladle warm au jus over the beef for a wet sandwich.
  9. Top with giardiniera or sweet roasted peppers as desired. Serve immediately.

Make-ahead

  • The roast can be cooked a day ahead and refrigerated in its cooking liquid. Reheat gently in the liquid before slicing and assembling sandwiches. Prepare giardiniera or peppers in advance to save time.

Notes

  • This recipe is a restaurant-inspired home adaptation based on Serious Eats and USDA guidelines. Use a whole-muscle roast like top sirloin or eye of round for best texture. Cooking to 145°F plus resting ensures safe doneness while maintaining juiciness. Thin slicing is key to authentic texture; a sharp knife or slicer helps. Giardiniera adds traditional spicy tang, but sweet roasted peppers are a common alternative. Common pitfalls include overcooking the roast, which can dry out the beef, and slicing too thick, which affects sandwich texture. Leftover au jus can be refrigerated and reheated gently. For a drier sandwich, omit dipping the roll in au jus. This recipe does not claim to replicate any specific restaurant's official recipe.

Why this recipe works

Cooking the beef in seasoned broth infuses flavor and keeps the meat moist, while resting allows juices to redistribute for tender slices. Thin slicing maximizes tenderness and sandwich mouthfeel. The au jus adds moisture and richness, replicating the classic wet sandwich experience.
