How to Make Instant Pot Italian Beef Sandwich with Pepperoncini and Giardiniera Recipe
Step 1: Sear the Beef for Maximum Flavor
Start by seasoning your chuck roast pieces generously with salt and pepper. Then, set your Instant Pot to ‘Sauté,’ heat the olive oil, and sear the beef until it develops a beautiful brown crust on all sides. This step locks in juices and creates an incredible depth of flavor that forms the base for the whole sandwich experience.
Step 2: Sauté Onions and Spices
After removing the seared beef, add the sliced onion to the pot and cook until it’s soft and translucent. Stir in the minced garlic, oregano, basil, and red pepper flakes. This fragrant mixture creates a robust aromatic profile that will soak into the beef as it cooks.
Step 3: Pressure Cook the Beef to Tender Perfection
Pour in the beef broth, Italian dressing, and pepperoncini brine—these liquids are the secret to the signature tang and moisture of the dish. Return the browned beef to the pot and add the sliced pepperoncini. Secure the lid, seal the valve, and cook on high pressure for 60 minutes. After cooking, allow a natural release for 10 minutes before quick releasing any remaining pressure.
Step 4: Shred the Beef and Prepare the Juices
Carefully remove the beef and shred it using two forks. Skim off any excess fat from the cooking liquid left in the pot. This juice-soaked beef is what makes the sandwich irresistibly juicy and flavorful.
Step 5: Toast the Rolls and Add Cheese (Optional)
Preheat your broiler and toast the rolls until they have a light golden crust. If you love a melty cheese topping, lay a slice of provolone on each toasted roll and broil just until the cheese becomes gooey and bubbly.
Step 6: Assemble Your Sandwich
Pile up shredded beef generously on each toasted roll, drizzle with some of the flavorful cooking juices, then top with a spoonful of giardiniera. This finishing touch introduces an exciting crunch and a spicy, vinegary bite that perfectly balances the rich beef. Serve immediately for the best experience.

Garnishes
Don’t be shy about extra toppings! Adding a few whole pepperoncini on the side gives an extra zing for those who want an additional kick. Fresh parsley or a sprinkle of grated Parmesan can also brighten up the plate and add a fresh herbal note to the presentation.
Side Dishes
Classic pairings like crispy fries, a fresh garden salad, or even creamy coleslaw work beautifully. The contrast of textures and flavors enhances the overall meal experience, making it even more satisfying. Roasted vegetables or a simple pasta salad also complement the rich beef beautifully.
Creative Ways to Present
For a party or casual get-together, turn this recipe into a sandwich bar with all the fixings laid out so everyone can customize their own. Offer a variety of cheeses, extra giardiniera, and different types of bread for fun. Or slice the sandwiches into smaller sliders for easy sharing that keeps everyone coming back for more.
Make Ahead and Storage
Storing Leftovers
You can store any leftover shredded beef with its cooking juices in an airtight container in the refrigerator for up to 4 days. This keeps the flavors vibrant and the beef tender, so your next sandwich will taste just as fresh.
Freezing
To extend its shelf life, freeze the shredded beef and juices in a freezer-safe container for up to 3 months. Thaw it slowly overnight in the fridge to maintain the best texture and flavor before reheating.
Reheating
Reheat the beef gently in a saucepan over low heat, adding a splash of broth if needed to keep it from drying out. Warm through until hot but avoid overheating to preserve tenderness. Toast fresh buns and add your favorite toppings for a quick, delicious meal anytime.
