How to Make Instant Pot Italian Beef Sandwich with Pepperoncini and Giardiniera Recipe
Step 1: Sear the Beef
Start by seasoning your chuck roast pieces with salt and pepper. Setting your Instant Pot to “Sauté” gives you that perfect high heat to brown the beef on all sides. This step is crucial because it locks in the juices and develops a deep, savory crust that makes the beef deliciously rich. Once browned, remove the beef and set it aside—don’t rush this step, as it builds the foundation for intense flavor.
Step 2: Sauté Aromatics and Spices
In the same pot, toss in the sliced onion and cook until it softens and turns translucent. Next, stir in minced garlic, dried oregano, basil, and red pepper flakes. The aromas released here are incredible and set the tone for the entire dish — a fragrant Italian herb and spice medley that will infuse the meat and cooking broth with warmth and subtle heat.
Step 3: Pressure Cook with Liquids and Peppers
Pour in the beef broth, Italian salad dressing, and the crucial pepperoncini brine — that liquid packs a punch, tenderizing the meat while giving it its signature tang. Return the beef to the pot along with the sliced pepperoncini. Seal the lid, set your Instant Pot to high pressure for 60 minutes, then allow a 10-minute natural pressure release before quick releasing any leftover steam. This method ensures the chuck roast becomes fall-apart tender while soaking up the flavorful cooking juices.
Step 4: Shred the Beef
Carefully remove the beef from the pot and shred it using two forks — it should pull apart effortlessly. Take a moment to skim off any excess fat from the cooking liquid to keep the sandwich juices flavorful but not greasy. This shredded beef is the heart of your Italian beef sandwich.
Step 5: Toast and Prepare the Rolls
Preheat your broiler and toast the French rolls or hoagie buns until they’re lightly golden and crisp on the edges. If you love a melty touch, place slices of provolone cheese on the warm toasted rolls and broil just enough to melt them. This creates the perfect vehicle for piling on the juicy beef.
Step 6: Assemble and Serve
Generously mound the shredded beef onto the toasted rolls, drizzle with some of the cooking juices for extra moisture and flavor, and top with chopped giardiniera. This final step layers in that satisfying crunch and acidity from the pickled vegetables, waking up your taste buds. Serve immediately while everything is hot and flavorful.
How to Serve Instant Pot Italian Beef Sandwich with Pepperoncini and Giardiniera Recipe

Garnishes
Adding fresh garnishes can elevate your sandwich experience. Try sprinkling with extra red pepper flakes or chopped fresh parsley for color and a bit of fresh herb brightness. A few additional pepperoncini slices on top can add a welcome tangy crunch for those who love a bit more bite.
Side Dishes
Classic sides like crispy French fries, a handful of crunchy coleslaw, or even a light Italian salad with vinaigrette make perfect companions to this hearty sandwich. These add contrasting textures and layers of flavor, balancing the richness of the beef.
Creative Ways to Present
For a fun twist, try serving the shredded beef open-faced on toasted bread with dollops of giardiniera on the side for guests to customize. Alternatively, roll it up in warm tortillas for an Italian beef wrap or even pile it on top of polenta or creamy mashed potatoes for a comforting Italian-American fusion meal.
Make Ahead and Storage
Storing Leftovers
Place any leftover shredded beef and juices in an airtight container and refrigerate. It will keep well for up to 3 to 4 days. Keeping the beef moist with its cooking liquid ensures it stays tender and flavorful when reheated.
Freezing
You can freeze the cooked beef mixture for longer storage. Portion it into freezer-safe containers or bags, removing as much air as possible. Frozen beef will maintain the best quality for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat gently on the stovetop over low to medium heat, adding a splash of water or beef broth if needed to loosen the sauce. You can also reheat in the microwave, covered to retain moisture, stirring occasionally to heat evenly.
FAQs
Can I use a different cut of beef for this recipe?
While chuck roast is ideal for its marbling and tenderness after pressure cooking, you can also use brisket or shoulder cuts. Just keep in mind the cooking time needs may vary slightly depending on the cut’s thickness and fat content.
What if I don’t have pepperoncini or giardiniera?
Pepperoncini provide essential tang and mild heat, so if you can’t find them, try substituting with mild banana peppers or pickled pepper slices and a splash of pickle juice. For giardiniera, you can mix chopped pickled vegetables like carrots, celery, and cauliflower with some olive oil and vinegar for a similar crunch and acidity.
Is the Instant Pot necessary for this recipe?
The Instant Pot speeds up the cooking significantly and locks in flavor, but you can make Italian beef sandwiches on the stovetop or slow cooker. Just allow longer cooking times to achieve that tender, pull-apart texture.
Can I prepare this recipe in advance for a party?
Absolutely! The beef actually tastes even better the day after the flavors have melded. Prepare the beef ahead, refrigerate, and reheat slowly before assembling the sandwiches just before serving.
Should I add the giardiniera before serving or mix it into the beef?
Giardiniera is best added fresh as a topping right before serving to keep its crunchy texture and vibrant flavor intact. Mixing it in ahead of time can make it soggy and less flavorful.
