Step‑by‑Step Instructions for Philly Cheese Steak Stuffed Shells
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures your Philly Cheese Steak Stuffed Shells bake evenly and come out perfectly bubbly and golden. While the oven warms up, gather your ingredients and equipment—a large skillet for sautéing, a mixing bowl for the filling, and a baking dish to hold your stuffed shells.
Step 2: Cook the Ground Beef
In a large skillet over medium heat, brown the lean ground beef until it is fully cooked, about 6-8 minutes. Use a wooden spoon to break it into smaller pieces as it cooks; you want a nice brown color, indicating delicious flavor development. Once cooked, transfer the beef to a bowl and set aside while you prepare the vegetables.
Step 3: Sauté the Vegetables
In the same skillet, melt 2 tablespoons of butter over medium heat and add the diced yellow onion and green bell pepper. Sauté these vegetables for about 4 minutes, stirring halfway through until they become soft and fragrant. This step enhances the filling with sweetness and balance, which perfectly complements the beef.
Step 4: Combine the Filling
In your mixing bowl, combine the sautéed vegetables with the browned ground beef. Stir in ketchup, Worcestershire sauce, kosher salt, and fresh ground black pepper, mixing until all ingredients are well combined. Finally, fold in half of the shredded cheddar cheese, ensuring it’s evenly distributed throughout the filling.
Step 5: Stuff the Pasta Shells
Next, take your cooked jumbo pasta shells and carefully stuff each one with the cheesy beef mixture. Arrange the stuffed shells in a greased baking dish, making sure they sit snugly against each other. This step keeps the flavors intact and allows the shells to absorb the deliciousness as they bake.
Step 6: Prepare the Cheese Sauce
In the same skillet, whisk together beef broth and milk over medium heat. Gradually add cornstarch while continuously whisking until the mixture thickens and bubbles, about 3-5 minutes. Slowly stir in the remaining shredded cheddar cheese until melted and creamy. This beautiful sauce will elevate your Philly Cheese Steak Stuffed Shells to new heights.
Step 7: Bake the Stuffed Shells
Pour half of the luscious cheese sauce over your stuffed shells, ensuring they’re well-covered. Place the baking dish in the preheated oven and bake for around 10 minutes, or until the cheese is melted and bubbly with a golden hue on top. This final touch brings everything together for a comforting and satisfying dish.
Step 8: Serve and Enjoy
Once baked, remove the Philly Cheese Steak Stuffed Shells from the oven and let them cool for a few minutes. Serve with the remaining cheese sauce on the side for drizzling. Gather your family around the table and enjoy this delightful twist on a classic cheesesteak!
