Italian Beef Recipe With Deli Roast Beef: Slow-Simmered Chicago-Style Sandwiches

This recipe transforms deli roast beef into a tender, flavorful Italian classic that rivals any Chicago sandwich shop. The slow-simmered approach coaxes maximum richness from modest ingredients.

The secret lies in the broth—a robust blend of Italian herbs, garlic, and peppers that infuses every bite with authentic character. I’ve tested this method repeatedly to ensure perfectly tender results every time.

You’ll end up with meat so tender it falls apart at the touch of a fork, ready to pile onto crusty rolls. The aromatic broth doubles as a dipping sauce for an extra layer of flavor.

Ideal for feeding a crowd or meal prepping for the week. Here’s how to make it.

Ingredients for Italian Beef Recipe with Deli Roast Beef

Deli roast beef meets Italian herbs and peppers for a Chicago-style classic.

The deli roast beef is the foundation. Ask for freshly sliced, not pre-packaged—it stays juicier during simmering. Most grocery delis use quality cuts, but Italian markets often have better marbling. The beef broth should be low-sodium so you can control the seasoning. I always use Swanson or Better Than Bouillon for consistent results. The jarred banana peppers add the signature tang—Mezzetta is the gold standard.

Out of Italian dressing mix? Make your own with oregano, basil, garlic powder, and onion salt. No banana peppers? Pepperoncini work in a pinch, though the flavor is slightly different. The garlic can be pre-minced from a jar if you’re short on time (just use an extra clove). For heat, fresh jalapeños can replace the red pepper flakes—add with the peppers for even cooking.

This tastes even better the next day. Store beef in broth in the fridge for up to 4 days, or freeze for 3 months. Reheat gently on the stove—microwaving can make the meat tough. The rolls are best toasted fresh, but you can prep them 1 day ahead and store at room temperature.

Step-by-Step Instructions for Italian Beef With Deli Roast Beef

This method delivers tender, flavorful beef with minimal effort and maximum authenticity.

Step 1: Sear the Deli Roast Beef

Heat the 2 tbsp olive oil in a large pot or Dutch oven over medium-high heat. Add the 2 lb deli roast beef in batches, being careful not to overcrowd the pan. Sear for 2-3 minutes per side until lightly browned.

This step builds a flavor foundation for the dish. The beef should develop a light crust but not cook through completely. Transfer the seared beef to a plate and set aside.

Step 2: Build the Flavor Base

In the same pot, add the 6 cloves garlic cloves, 0.25 cup Italian dressing mix, 2 tsp dried oregano, 2 tsp dried basil, 1 tsp crushed red pepper flakes, 1 tsp black pepper, and 1 tsp kosher salt. Stir for 1 minute until fragrant.

Pour in the 4 cups beef broth and scrape up any browned bits from the bottom of the pot. These bits contain concentrated flavor that will enrich the sauce. Stir well to combine all the ingredients.

Step 3: Simmer the Beef Until Tender

Return the seared deli roast beef to the pot along with any accumulated juices. Add the 1 jar banana peppers with their juice. Bring the mixture to a simmer, then reduce the heat to low.

Cover and let it cook for 1.5-2 hours, stirring occasionally, until the beef is fall-apart tender and the flavors have melded together. The liquid should reduce slightly but still remain saucy.

Step 4: Toast the Rolls and Assemble the Sandwiches

Split the 4 whole crusty Italian rolls and lightly butter the cut sides with the 2 tbsp sweet butter. Toast them in a skillet over medium heat for 1-2 minutes per side until golden brown.

Place a generous portion of the beef and its juices onto the bottom half of each roll. Top with a slice of provolone cheese if desired, then cap with the top half. Serve immediately while hot.

Essential Equipment for This Dish

Essential Pot

I always reach for my 5-quart Dutch oven—the Lodge enameled cast iron is my workhorse. It distributes heat evenly and holds up to the 2-hour simmer without hot spots. A heavy-bottomed stockpot works too, but avoid thin aluminum pots. 💪

Wooden Spoon

A long wooden spoon lets you stir the beef without breaking it apart too much. I keep one dedicated to savory dishes to avoid any lingering sweet flavors from other recipes. It also won’t scratch your pot’s surface.

Sharp Knife

For slicing the rolls, a serrated bread knife is non-negotiable. My 8-inch Wüsthof glides through crusty Italian rolls without crushing them. A dull knife will squash your bread and make a mess.

Tongs for Beef

Use 12-inch locking tongs to transfer the seared beef in and out of the pot. They give you precision without piercing the meat. I tested this with a spatula once—disaster. The tongs also help separate the beef for serving.

Measuring Tools

Keep a set of nesting measuring cups and spoons handy for the dressing mix and spices. I love my OXO Good Grips set—the magnetic handles stay organized in my tiny Boston kitchen. Exact measurements matter for consistent flavor.

Butter Brush

For the rolls, a silicone pastry brush spreads the melted butter evenly. It’s heat-resistant and easy to clean. I keep one in my utensil crock just for this purpose. 🔥
