Chicago Italian Beef Sliders with Giardiniera

The Italian beef sandwich is the most famous food of Chicago — a crusty roll piled high with thinly sliced, slowly braised beef, dipped in savory jus, and topped with spicy giardiniera. It was invented in Chicago's Italian-American community in the 1930s, when butchers and street vendors slow-roasted inexpensive cuts of beef, sliced them paper-thin, and served them on crusty Italian bread. The dish became a staple of Chicago's working-class Italian neighborhoods — Taylor Street, the Near West Side — and was popularized by restaurants like Al's #1 Italian Beef (opened 1938) and Portillo's. For a party, miniature slider versions of the Italian beef are an ideal hand-held appetizer that packs enormous flavor into a small bite.

The defining elements of the Chicago Italian beef are: a beef roast (typically bottom round or sirloin tip) slow-roasted until tender, then sliced paper-thin and returned to its own juices (the "au jus" or "gravy"); a crusty Italian roll (Turano or Gonnella bread are the Chicago standards); and giardiniera — a Chicago-specific condiment of pickled vegetables (celery, cauliflower, carrots, peppers) preserved in oil. The sandwich is ordered "dipped" (the entire sandwich submerged in jus), "wet" (extra jus spooned over), or "dry" (jus on the side).

About the Ingredients

Beef should be a bottom round roast or sirloin tip roast — lean, inexpensive cuts that become tender through slow braising. The meat is seasoned with a dry rub of Italian herbs (oregano, basil, garlic powder, crushed red pepper) and slow-roasted to an internal temperature of 190–195°F (88–196°F), which allows the connective tissue to break down completely. It is then sliced paper-thin — ideally on a meat slicer, but a very sharp knife against the grain works well.

Giardiniera is the essential Chicago condiment. Chicago-style giardiniera is a blend of pickled vegetables — celery, cauliflower, carrots, bell peppers, and sport peppers — preserved in oil (not vinegar, as in the Italian original). Scala's and Vienna Beef make the leading Chicago giardiniera brands. It is available in mild and hot varieties — hot is the traditional choice for Italian beef.

Rolls should be small, crusty Italian rolls — mini Turano or Gonnella rolls if available, or small French dinner rolls. The bread must be sturdy enough to hold the juicy beef without falling apart.

Ingredients (makes 24 sliders): - 1 bottom round beef roast (4–5 lbs) - 1 tablespoon dried oregano - 1 tablespoon garlic powder - 1 teaspoon crushed red pepper flakes - 1 teaspoon salt - 1 teaspoon black pepper - 2 tablespoons olive oil - 4 cups beef broth - 2 tablespoons Italian seasoning - 3 cloves garlic, minced - 1 bay leaf - 24 small crusty Italian rolls (slider size) - 1 jar (16 oz) Chicago-style hot giardiniera, drained - 6 provolone cheese slices, quartered (optional)

Instructions: Preheat the oven to 300°F (302°F).

In a small bowl, combine the oregano, garlic powder, red pepper flakes, salt, and black pepper. Rub the beef roast with olive oil, then coat generously with the seasoning blend on all sides.

Place the roast in a Dutch oven or roasting pan. Add the beef broth, Italian seasoning, minced garlic, and bay leaf. Cover tightly with a lid or foil. Roast for 3–4 hours until the beef is fork-tender and reaches an internal temperature of 190–195°F (88–196°F).

Remove the beef from the pan and let it rest for 15 minutes. Strain the cooking liquid into a bowl — this is the au jus. Skim excess fat from the surface.

Slice the beef as thinly as possible — ideally on a meat slicer. If slicing by hand, chill the beef for 30 minutes first to firm it up, then slice against the grain with a very sharp knife.

Return the sliced beef to the au jus in a wide pan. Keep warm over low heat. The beef should be submerged — it will continue to absorb flavor.

To assemble: split the slider rolls. Pile a generous amount of juicy beef onto each roll. Top with a spoonful of giardiniera and a piece of provolone if using. For "dipped" style, briefly dip the assembled slider into the au jus. Serve immediately.

The Mimosa Pairing Logic: The rich, savory beef, the spicy giardiniera, and the au jus-soaked bread call for a bright, acidic beverage to cut through the richness and refresh the palate. A classic Champagne mimosa or a blood orange mimosa is ideal — the citrus acidity cuts through the beef and the oil from the giardiniera, while the wine's effervescence cleanses the palate between bites. The blood orange in the mimosa echoes the Italian heritage of the dish, while the wine's bright fruit provides a refreshing counterpoint to the beef's deep, savory richness.

Make-Ahead: The beef can be roasted and sliced up to 2 days ahead — store the sliced beef submerged in the au jus in the refrigerator. Reheat gently in a saucepan over low heat. The giardiniera can be purchased ready-made and keeps for months in the refrigerator. Assemble the sliders just before serving — the bread will become soggy if assembled too far ahead. For "dipped" style, dip at the very last moment.

Pro Tips: The beef must be sliced paper-thin — this is non-negotiable. Thick slices are chewy and unappetizing; thin slices melt in the mouth. Chilling the roast before slicing firms the meat and allows for thinner cuts. The au jus should be rich and well-seasoned — taste it and adjust salt before returning the beef. The giardiniera should be the Chicago-style (oil-packed) variety — the oil is part of the flavor and the texture. Do not substitute vinegar-pickled giardiniera. The rolls must be sturdy — soft buns will disintegrate under the weight of the juicy beef.
