Chicago Italian Beef Sandwiches

True Chicago Italian beef is a sandwich of contradictions. Tender, gravy-soaked beef tucked into crusty Italian bread that somehow holds it all together. This version uses leftover roast beef instead of starting from raw, which is exactly how it’s done in Italian-American kitchens across the Windy City.

Thin slicing is the key. Use the sharpest knife you have and slice across the grain into nearly translucent pieces. Thick chunks turn rubbery in the gravy. Paper-thin slices melt against your teeth.

The gravy gets its character from oregano, basil, whole peppercorns, and red pepper flakes simmering in beef juices for a full hour. That hour lets the herbs infuse the broth and turn it into the famous au jus that Chicagoans use to baptize their sandwiches.

Dipping the sandwich in gravy at serving is the signature move. Order it “wet” and the whole sandwich gets a quick plunge before being passed back to you on a plate, dripping and barely structural. Lean over, do not wear a white shirt.

Pro Tips

• Slice the beef while it’s still slightly cold from the fridge. Cold meat slices thinner than warm.
• Use the same pan you roasted the beef in. The browned fond on the bottom is liquid gold for the gravy.
• Grilled or sautéed green peppers are the traditional topping, but giardiniera (Chicago-style spicy pickled vegetable relish) is the move for authentic heat.
• A crusty French or Italian sub roll holds up best. Soft hoagie buns will dissolve.

Variations

• Add provolone slices and melt under a broiler for a cheesy variation.
• Use the recipe to fill meatball subs or stuff into baked potatoes.
• Top with sweet peppers and pepperoncini if you don’t have giardiniera.
