Ingredients

For the perfect Slow Cooker Italian Beef Sandwiches, you’ll need:

• 3-4 pounds (1.4-1.8 kg) chuck roast or bottom round roast
• 2 tablespoons (30 ml) olive oil
• 2 teaspoons (10 g) kosher salt
• 1 teaspoon (5 g) freshly ground black pepper
• 1 tablespoon (9 g) Italian seasoning
• 1 teaspoon (3 g) garlic powder
• 1 teaspoon (2 g) onion powder
• ½ teaspoon (1 g) red pepper flakes (optional)
• 2 cups (480 ml) beef broth (low sodium preferred)
• 1 cup (240 ml) pepperoncini juice (from the jar)
• 8-10 pepperoncini peppers, plus more for serving
• 1 large onion, sliced
• 4 garlic cloves, minced
• 8-10 crusty Italian rolls or hoagie buns
• Provolone cheese slices (optional)

The quality of the beef is particularly important – choose a well-marbled chuck roast for the most tender results. Authentic Italian beef sandwiches use pepperoncini peppers, which provide a mild tang rather than heat, so don’t skip this crucial ingredient.

Pro Tips

Sear the Beef First
Take the extra 10 minutes to brown your beef thoroughly before adding it to the slow cooker. This crucial step develops a rich depth of flavor through the Maillard reaction, creating those delicious browned bits that will infuse the entire dish. Heat your oil until it’s shimmering, then sear each side of the roast for 3-4 minutes until it develops a deep brown crust.

Don’t Rush the Process
The magic of Slow Cooker Italian Beef Sandwiches happens during the low, slow cooking process. Cook on low for 8-10 hours rather than on high for a shorter time. This patience allows the connective tissues to break down properly, resulting in that signature fall-apart tenderness that makes this sandwich special. If you try to speed up the process, you’ll end up with meat that’s either tough or mushy.

Perfect Your Dipping Technique
Authentic Italian beef sandwiches in Chicago are often served “wet” or “dipped.” After assembling your sandwich with the beef and desired toppings, use tongs to briefly dip the entire sandwich into the hot jus before serving. This creates the ultimate juicy sandwich experience. For less mess, serve the jus on the side in small ramekins for diners to dip as they eat.

Instructions

Step 1: Prepare and Sear the Beef
Pat the beef roast dry with paper towels to ensure proper browning. In a small bowl, combine salt, pepper, Italian seasoning, garlic powder, onion powder, and red pepper flakes. Rub this seasoning mixture all over the roast, pressing it into the meat. Heat olive oil in a large skillet over medium-high heat until shimmering. Carefully place the seasoned roast in the hot skillet and sear each side for 3-4 minutes until deeply browned. This step is worth every minute for the flavor it develops.

Step 2: Prepare the Slow Cooker
Place sliced onions and minced garlic in the bottom of your slow cooker, creating a flavorful bed for the meat. Transfer the seared beef to the slow cooker, placing it on top of the onions and garlic. Pour in beef broth and pepperoncini juice, then scatter the pepperoncini peppers around the roast. The liquid should come about halfway up the sides of the roast – not completely submerging it.

Step 3: Slow Cook to Perfection
Cover the slow cooker and set it to low for 8-10 hours. Resist the temptation to peek frequently, as this releases precious heat and extends cooking time. You’ll know it’s ready when the beef effortlessly shreds with just the touch of a fork. The patience required here rewards you with meat so tender it practically melts.

Step 4: Shred and Prepare the Beef
Once the beef is fall-apart tender, carefully transfer it to a cutting board. Using two forks, shred the meat into bite-sized pieces, removing any large pieces of fat as you go. Return the shredded beef to the slow cooker and stir gently to combine with the juices. Let it absorb those flavors for another 15-30 minutes on the warm setting.

Step 5: Prepare the Bread
While the beef is finishing, prepare your rolls. For authentic Chicago-style Slow Cooker Italian Beef Sandwiches, slice crusty Italian rolls or hoagie buns horizontally, keeping them connected on one side. If desired, place provolone cheese on the bottom half of each roll and toast them lightly under the broiler for 1-2 minutes until cheese starts to melt and bread is lightly crisp.

Step 6: Assemble and Serve
Using a slotted spoon, pile the shredded beef generously onto the prepared rolls. Add additional pepperoncini peppers if desired. For the full experience, use tongs to briefly dip the entire sandwich into the hot jus (or serve jus on the side in small ramekins for dipping). Serve immediately while hot, with napkins handy – these delicious sandwiches can get wonderfully messy!

Variations

Spicy Italian Beef Sandwiches
For those who enjoy heat, transform your Slow Cooker Italian Beef Sandwiches into a spicier version by adding 1-2 sliced jalapeños or a hot giardiniera mix to the slow cooker along with the pepperoncini. The vegetables will infuse the meat with a pleasant heat that builds with each bite. When serving, top each sandwich with additional hot giardiniera for an authentic Chicago-style spicy beef sandwich that will clear your sinuses in the most delicious way.

Garlic-Herb Italian Beef
Enhance the herb profile by doubling the Italian seasoning and adding 2 teaspoons of dried basil and 1 teaspoon of dried oregano to the rub. Increase the garlic to 6-8 cloves for an aromatic variation that pairs beautifully with garlic-buttered and toasted rolls. This garlic-herb version offers a more Mediterranean flavor profile that works wonderfully when topped with roasted red peppers and a sprinkle of fresh parsley before serving.

Keto-Friendly Option
Make these Slow Cooker Italian Beef Sandwiches keto-friendly by serving the meat and toppings on a bed of sautéed bell peppers and onions instead of rolls. Alternatively, use lettuce wraps or low-carb wraps. The flavorful beef is so satisfying that you won’t miss the bread, and you’ll still get all the signature flavors of the classic sandwich without the carbs.

Storage and Serving

The beef from these Slow Cooker Italian Beef Sandwiches stores beautifully, making excellent leftovers. Cool completely, then store the meat and jus together in airtight containers in the refrigerator for up to 4 days. For longer storage, freeze in portion-sized containers for up to 3 months. Reheat gently on the stovetop or microwave until just hot, being careful not to overcook and dry out the meat.

For an impressive dinner spread, serve your Slow Cooker Italian Beef Sandwiches with a variety of toppings and sides. Create a sandwich bar with extra pepperoncini, sliced provolone, sautéed bell peppers, and both mild and hot giardiniera. Classic accompaniments include crispy french fries, vinegar-based coleslaw, or a simple Italian salad dressed with vinaigrette.

For a complete Chicago-themed meal, serve these sandwiches alongside Chicago-style hot dogs and a deep-dish pizza. It’s a crowd-pleasing feast perfect for game days or casual entertaining that lets everyone customize their sandwich to their preference.

FAQs

Can I use a different cut of beef for Slow Cooker Italian Beef Sandwiches?
Yes, while chuck roast is ideal, you can also use brisket, rump roast, or bottom round. The key is choosing a tougher cut with good marbling that benefits from long, slow cooking. Leaner cuts like sirloin will become too dry.

What if I don’t like pepperoncini peppers?
The pepperoncini provide the signature tangy flavor in Slow Cooker Italian Beef Sandwiches, but you can reduce the amount or substitute with banana peppers for a milder tang. If you omit them entirely, add 2 tablespoons of vinegar to maintain some acidity in the dish.

Can I make this in an Instant Pot instead of a slow cooker?
Absolutely! Sear the beef using the sauté function, then pressure cook on high for 60-70 minutes with a natural pressure release. The result won’t be quite as tender as the slow-cooked version, but it’s a good option when time is limited.

How can I thicken the au jus if it’s too thin?
For authentic Slow Cooker Italian Beef Sandwiches, the jus should remain thin. However, if you prefer a thicker sauce, remove 1 cup of liquid, whisk in 1 tablespoon of cornstarch, and return it to the pot, stirring until slightly thickened.

What’s the best way to reheat leftover Italian beef?
For best results, reheat the beef and jus together over low heat until just warmed through. Avoid high heat or lengthy reheating, which can make the meat tough. Adding a splash of fresh beef broth can revive the flavors if needed.
