What are Italian Beef Sandwiches?

Italian Beef Sandwiches are a Chicago classic, typically made with thinly sliced or shredded beef that’s been slow-cooked in a flavorful broth with Italian herbs, garlic, and pepperoncini. The beef is then piled high on a crusty roll and often topped with melted cheese, sautéed peppers, or giardiniera (a pickled vegetable mix). What sets Italian beef sandwiches apart is the savory, tangy flavor of the beef, which comes from the combination of spices and briny pepperoncini peppers. The result is a juicy, savory sandwich that's bursting with flavor.

1 tablespoon dried Italian seasoning (oregano, basil, thyme)
1 teaspoon garlic powder
1 teaspoon onion powder
½ teaspoon crushed red pepper flakes (optional, for a bit of heat)
2 cups beef broth (low-sodium works best)
1 (12 oz) jar pepperoncini peppers (with juice)
¼ cup balsamic vinegar (optional, for extra tangy flavor)
1 onion, sliced (optional, for extra flavor)
4 cloves garlic, minced

Substitutions and Variations

This slow cooker Italian beef recipe is easy to customize, depending on your taste or what you have on hand. Here are some substitutions and variations to try:

Different cuts of beef: Chuck roast is ideal because it’s tender and shreds easily, but you can also use bottom round roast or brisket if you prefer.
Add veggies: Sautéed bell peppers, onions, or mushrooms can be added to the sandwich for more texture and flavor. You can also slow cook the beef with the vegetables for extra depth.
Spice it up: Add more crushed red pepper flakes or even a few slices of fresh jalapeños if you want a spicier sandwich.
Cheese options: While provolone is a classic choice, you can use mozzarella, pepper jack, or even cheddar for a unique twist.
Gluten-free option: Use gluten-free rolls or serve the beef over a baked potato, mashed potatoes, or a bed of lettuce for a gluten-free meal.

Step-by-Step Cooking Instructions

Prep the Beef: Start by seasoning the chuck roast with salt and pepper on all sides. You can also sprinkle on a bit of the Italian seasoning for extra flavor.
Sear the Roast (Optional): For an added layer of flavor, sear the beef in a hot skillet with a little olive oil over medium-high heat for 2-3 minutes per side, until browned. This step is optional but helps lock in the flavor. Transfer the beef to the slow cooker.
Add the Seasonings and Broth: In the slow cooker, pour the beef broth, balsamic vinegar (if using), and the entire jar of pepperoncini peppers (including the juice) over the roast. Add the packet of Italian dressing mix, garlic powder, onion powder, dried Italian seasoning, minced garlic, and crushed red pepper flakes. Stir gently to combine.
Slow Cook: Cover the slow cooker and cook on low for 8-10 hours or high for 4-6 hours, until the beef is fall-apart tender and shreds easily with a fork.
Shred the Beef: Once the beef is done, remove it from the slow cooker and use two forks to shred it. Discard any large pieces of fat. Return the shredded beef to the slow cooker to soak up the juices for another 15-20 minutes on low.
Prepare the Sandwiches: Preheat your oven to 350°F (175°C). Slice the rolls open, lay them on a baking sheet, and top each half with a generous amount of shredded beef. Add a slice or two of provolone or mozzarella cheese on top of the beef. Place the sandwiches in the oven and bake for about 5-7 minutes, or until the cheese is melted and bubbly.
Serve: Remove the sandwiches from the oven and serve hot, optionally topping them with giardiniera or sautéed peppers and onions. Don’t forget to offer some of the delicious cooking juices (au jus) for dipping!

How to Cook Slow Cooker Italian Beef Sandwiches: A Step-by-Step Guide

Step 1: Season and optionally sear the beef for extra flavor.
Step 2: Add beef broth, pepperoncini, and seasonings to the slow cooker.
Step 3: Slow cook the beef on low for 8-10 hours until it’s tender and shreddable.
Step 4: Shred the beef and let it soak in the juices.
Step 5: Prepare the rolls, top with cheese, and bake until the cheese melts.
Step 6: Serve hot, with optional giardiniera and a side of au jus for dipping.

Common Mistakes to Avoid

Not letting the beef cook long enough: To achieve that fall-apart tenderness, it’s crucial to cook the beef long enough—preferably the full 8-10 hours on low. If your beef isn’t shredding easily, it likely needs more time.
Using too lean of a cut: A chuck roast is ideal for this recipe because of its marbling, which makes it tender after slow cooking. Avoid using lean cuts like sirloin, which may turn out dry.
Forgetting to adjust seasoning: Taste the cooking liquid and beef once the meat is shredded and adjust the salt and seasonings if necessary. Sometimes the beef broth or dressing mix can make it salty, so taste as you go.

Serving and Presentation Tips

Italian beef sandwiches are all about bold flavors, and you can make them even more delicious with thoughtful presentation and sides. Here’s how you can serve these sandwiches for the best experience:

Serve with a side of au jus: The flavorful juices left in the slow cooker are perfect for dipping your sandwich. Ladle some into small bowls and serve alongside the sandwiches.
Add giardiniera or sautéed veggies: Giardiniera, a pickled vegetable relish, is a classic topping for Italian beef sandwiches. If you prefer, sautéed bell peppers and onions also add a great flavor boost.
Crisp up the bread: Before assembling the sandwiches, brush the rolls with a little olive oil or butter and lightly toast them in the oven for a crispy texture.

How to Serve Slow Cooker Italian Beef Sandwiches

Individual sandwiches: Place each Italian beef sandwich on a plate, with a small bowl of au jus for dipping.
Party-style: For a gathering, serve the shredded beef in a large dish alongside a basket of rolls, cheese, and toppings, allowing guests to assemble their own sandwiches.
With sides: Pair the sandwiches with sides like potato chips, fries, coleslaw, or a simple green salad for a well-rounded meal.

Presentation Ideas for Slow Cooker Italian Beef Sandwiches

Rustic style: Serve the sandwiches on a wooden cutting board with small bowls of au jus, giardiniera, and sautéed veggies for a visually appealing, rustic presentation.
Open-faced sandwiches: For a different take, serve the shredded beef on the open half of the roll, topped with cheese and broiled until melted. Garnish with fresh parsley or cilantro for color.
