Step‑by‑Step Instructions for Quick Chicago Beef Sandwiches

Step 1: Preheat the Oven and Prepare the Baking Sheet
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a parchment-lined baking sheet and set it aside. This will ensure easy cleanup and help your Quick Chicago Beef Sandwiches get perfectly crispy without sticking as they bake.

Step 2: Prepare the Baguettes
Using a serrated knife, cut each French baguette roll about 75% of the way through, creating a pocket for the filling. Next, in a small bowl, combine melted unsalted butter with minced garlic cloves, then generously brush the inside of each baguette with this flavorful garlic butter mixture, ensuring each bite will be infused with deliciousness.

Step 3: Toast the Baguettes
Place the prepared baguettes on the baking sheet and bake them in the preheated oven for about 10 minutes or until they are golden brown and toasted. Keep an eye on them to achieve that perfect crispy exterior, then once toasted, remove the rolls from the oven and set them aside to cool slightly while you prepare the au jus.

Step 4: Prepare the Au Jus
In a medium-sized pot, bring beef broth to a gentle boil over medium-high heat. Season the broth generously with dried oregano, garlic, onion, and chili flakes to your taste. Allow it to simmer for about 5–7 minutes, letting all those wonderful flavors meld together, creating the perfect dipping sauce for your Quick Chicago Beef Sandwiches.

Step 5: Warm the Roast Beef
Once the broth is ready, take the thinly sliced London Broil deli roast beef and dunk each slice into the hot broth for 10–15 seconds. This step ensures the beef is warmed through and flavorful. After dunking, place the slices on a tray to keep warm while you assemble the sandwiches.

Step 6: Assemble the Sandwiches
To create your Quick Chicago Beef Sandwiches, layer the warm roast beef generously inside the toasted baguettes, followed by a hefty amount of freshly grated whole milk mozzarella. The warmth from the beef will begin to melt the cheese, adding to that gooey texture we all love.

Step 7: Melt the Cheese
Return the assembled sandwiches to the oven and bake for an additional 5–7 minutes, or until the mozzarella cheese is ooey-gooey and bubbly. Keep a close eye on them, as ovens can vary; you want that beautiful, melted cheese without burning the bread.

Step 8: Optional Toppings and Serve
For an authentic Chicago experience, top your melted sandwiches with a generous helping of Chicago giardiniera if you desire a tangy and spicy kick. Afterward, carefully close the sandwiches and serve immediately, enjoying the delightful warmth and flavors of your Quick Chicago Beef Sandwiches.
