Step‑by‑Step Instructions for Authentic Portillo’s Italian Beef Sandwich Recipe
Step 1: Prepare the Beef
Begin by seasoning your beef roast generously with Italian seasoning, ensuring an even coating. In a large skillet over medium-high heat, heat a splash of oil and sear the roast until it achieves a rich, brown crust on all sides, about 4 minutes per side. This step enhances the flavors of your Portillo’s Italian beef sandwich.
Step 2: Slow Cook the Beef
Transfer the seared beef to a slow cooker and add the beef broth, allowing it to cover the meat halfway. Sprinkle additional Italian seasoning over the top and nestle sliced bell peppers and onions around the roast. Set the slow cooker to low and let it work its magic for 6 to 8 hours, until the beef is fork-tender and infused with savory flavors.
Step 3: Shred the Meat
Once cooking time is complete, carefully remove the beef from the slow cooker using tongs. Place it on a cutting board and shred it using two forks, letting the tender shreds soak in the juices briefly. Return the shredded meat back to the slow cooker, mixing it with the flavorful broth for a juicy Portillo’s Italian beef filling.
Step 4: Toast the Rolls
While the beef is absorbing its juices, preheat your oven to 350°F (175°C). Slice your sandwich rolls in half and place them on a baking sheet. Toast them in the oven for about 5-7 minutes, or until they are lightly golden and crispy on the edges. This step adds a delightful crunch to your finished Italian beef sandwich.
Step 5: Assemble the Sandwiches
To assemble, take the toasted rolls and generously pile high with the shredded beef, ensuring each sandwich gets plenty of the flavorful juices. Drizzle your favorite barbecue sauce over the meat to add a touch of tangy sweetness. Optionally, top with sautéed peppers and onions for a burst of additional flavor and texture, completing your authentic Portillo’s Italian beef sandwich experience.
