- 3 pounds beef chuck roast: Perfect for slow-cooking to juicy, shreddable tenderness.
- 1 tablespoon olive oil: Helps sear the beef, locking in rich flavor and color.
- 1 teaspoon salt: Enhances all the savory flavors in the beef and broth.
- 1/2 teaspoon black pepper: Adds a mild heat and subtle earthiness.
- 1 teaspoon dried oregano: Brings classic Italian herbal aroma that complements beef beautifully.
- 1 teaspoon dried basil: Adds sweetness and depth to the seasoning mix.
- 1 teaspoon onion powder: Contributes subtle umami and aroma without overpowering.
- 1/2 teaspoon garlic powder: Provides warm, savory notes essential for Italian flavor.
- 1 teaspoon crushed red pepper flakes (optional): Gives a gentle kick that wakes up the palate.
- 1 packet Italian dressing mix (about 1 oz): A brilliant shortcut for complex seasoning.
- 2 cups beef broth: The liquid base that steams the meat and creates flavorful jus.
- 1/2 cup pepperoncini peppers with juice: Infuses the dish with tangy, zesty heat and acidity.
- 6 hoagie rolls or sandwich buns: Soft yet sturdy vessels for holding all that beefy goodness.

How to Make Italian Beef Sandwiches with Pepperoncini and Giardiniera Recipe
Step 1: Sear the Beef for Maximum Flavor
Start by heating olive oil in a large skillet over medium-high heat. Season your beef chuck roast well with salt and pepper, then sear it on all sides until it forms a deep, golden-brown crust. This step is crucial because it locks in the beef’s juices and creates a fantastic base flavor that will carry through the slow cooking process.
Step 2: Build the Flavorful Slow Cooker Mix
Transfer the beautifully browned roast to your slow cooker. Sprinkle in dried oregano, basil, onion powder, garlic powder, crushed red pepper flakes (if you want a little extra heat), and the Italian dressing mix. Pour in the beef broth along with the pepperoncini peppers and their juice. These ingredients will mingle and soak into the beef as it cooks, creating that signature tangy flavor that defines the Italian Beef Sandwiches with Pepperoncini and Giardiniera Recipe.
Step 3: Slow Cook to Tender Perfection
Cover the slow cooker with its lid and cook the beef on low heat for about 8 hours. This long, slow cooking time allows the meat to break down and become incredibly tender—so tender it practically falls apart with a fork. The low heat also lets the spices fully infuse the beef, making every shred bursting with flavor.
Step 4: Shred and Soak the Beef
Once your roast is tender, carefully shred the beef right in the slow cooker using two forks. Stir the shredded meat back into the cooking juices to let it soak up even more of those delicious flavors. Keep it warm on the low setting for an additional 15 to 30 minutes to let the beef soak and get juicier before assembling your sandwiches.
Step 5: Prepare Your Rolls and Assemble
While the beef is soaking, toast your hoagie rolls or sandwich buns if you like a bit of extra crunch and structure. Then, pile the shredded beef generously inside each roll. Top with a scoop of giardiniera for a crunchy, spicy contrast or add a slice of provolone or mozzarella cheese to melt over the warm beef. These layers of texture and flavor make every bite truly delightful.
Step 6: Serve Hot with Au Jus for Dipping
Serve the Italian Beef Sandwiches with Pepperoncini and Giardiniera Recipe hot and fresh, with a small bowl of the warm cooking juices (au jus) alongside for dipping. Dipping each savory, tender bite into the tangy jus is pure sandwich bliss that adds juiciness and enhances the overall experience.

Garnishes
The perfect garnish for these sandwiches is a spoonful of cool, spicy giardiniera which adds crunch and acidity to balance the rich beef. Thinly sliced banana peppers or extra pepperoncini also bring a bright, lively punch. For cheese lovers, a melted slice of provolone or mozzarella adds creaminess that complements the tangy, tender meat beautifully.
Side Dishes
Italian Beef Sandwiches with Pepperoncini and Giardiniera Recipe tastes amazing with simple sides like crispy potato chips, a fresh green salad, or roasted vegetables. For a heartier meal, creamy coleslaw or garlic parmesan fries make for irresistible pairings. Keep the sides simple so the star—the sandwich—shines front and center.
Creative Ways to Present
Want to impress? Serve these sandwiches open-faced on toasted rolls with melted cheese broiled on top for a delightful finish. You can also create mini sliders for casual parties by cutting the beef into smaller portions and layering with giardiniera on slider buns. For meal prep or picnic style, wrap the sandwiches tightly in parchment paper and keep the au jus separate so guests can dip as much as they like.
Make Ahead and Storage
Storing Leftovers
These sandwiches are even better the next day. Store leftover shredded beef in its cooking juices in an airtight container in the refrigerator for up to 4 days. Keep your sandwich rolls separate to maintain their fresh texture.
Freezing
If you want to save these Italian Beef Sandwiches with Pepperoncini and Giardiniera Recipe for later, freeze the shredded beef in its juices in freezer-safe containers or bags for up to 3 months. Thaw overnight in the fridge before reheating gently.
Reheating
Reheat the beef slowly on the stovetop or in the microwave with a splash of beef broth or the reserved au jus to keep it moist. Toast your rolls fresh before assembling reheated beef and toppings for that delicious just-made taste.
FAQs
Can I use a different cut of beef?
Absolutely! While beef chuck roast is ideal for slow cooking because of its marbling and tenderness, you can also use brisket or bottom round. Just keep in mind these cuts might need slightly different cooking times.
Is giardiniera necessary?
Giardiniera adds a wonderful spicy, tangy crunch that perfectly contrasts the rich beef. However, if you don’t have it, you can substitute with pickled pepperoncini, banana peppers, or even crunchy pickles.
Can I make this recipe spicy?
Yes! Increase the amount of crushed red pepper flakes or add fresh jalapeños to the slow cooker for a kick. The pepperoncini also add mild heat that brightens the dish.
What kind of cheese works best?
Provolone and mozzarella are classic choices because they melt beautifully and have mild flavors that complement the sandwich. Fontina or Monterey Jack also work well if you want to mix things up.
Can I cook this in an Instant Pot?
Definitely! After searing the beef in the Instant Pot on sauté mode, add all other ingredients, seal the lid, and cook on high pressure for about 60 minutes, then allow natural pressure release. This shortcut saves time while maintaining tender, juicy beef.
