Step‑by‑Step Instructions for Philly Cheese Steak Stuffed Shells
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This ensures the cooking environment is perfect for baking the Philly Cheese Steak Stuffed Shells evenly. While the oven heats, gather your ingredients and prepare your cooking space for a smooth cooking experience.
Step 2: Cook Beef
In a large skillet, over medium heat, brown the ground beef until it’s fully cooked, which should take about 6-8 minutes. As you cook, break it up into small pieces with a spatula until it’s no longer pink. This step infuses the base flavor for your filling; once done, remove the beef from the skillet and set it aside.
Step 3: Sauté Vegetables
In the same skillet, add a tablespoon of butter and toss in the finely diced yellow onion and green bell pepper. Sauté the mixture for about 4 minutes, stirring occasionally, until the vegetables become tender and fragrant. This creates a delightful aroma that enhances the Philly Cheese Steak Stuffed Shells filling.
Step 4: Combine
Return the cooked ground beef to the skillet and add in the ketchup, Worcestershire sauce, salt, and black pepper. Stir everything together until well combined, allowing the flavors to meld for about 2 minutes. Finally, mix in half of the shredded cheddar cheese until melted and gooey, making your filling irresistibly tasty.
Step 5: Stuff Shells
Cook the jumbo pasta shells according to package instructions until al dente, usually about 9-11 minutes. Drain the shells and let them cool slightly. Once ready, carefully spoon the flavorful beef mixture into each shell, ensuring they’re filled generously. This is the fun part, so don’t rush—get those shells packed!
Step 6: Make Sauce
Using the same skillet, now add the beef broth and milk, whisking in the cornstarch gradually. Cook for about 3-5 minutes on medium heat until the sauce thickens slightly. As soon as it reaches a creamy consistency, stir in the remaining cheddar cheese until melted. This sauce will add richness to your Philly Cheese Steak Stuffed Shells.
Step 7: Bake
Spread about half of the cheese sauce on the bottom of a baking dish. Arrange the stuffed shells on top, then pour the remaining sauce over them. Bake in the preheated oven for approximately 10 minutes, until the cheese is bubbling and delightful. Keep an eye on the edges, where the cheese should turn a golden brown.
Step 8: Serve
Once baked, remove your Philly Cheese Steak Stuffed Shells from the oven and let them cool for a minute. Drizzle any remaining sauce over the top before diving in! These cheesy, comforting shells are now ready to enjoy, bringing smiles to your family table.

You can store your leftover stuffed shells in an airtight container in the fridge for up to 3 days. Reheat them in the microwave or bake in a 350°F (175°C) oven until heated through. For best results, cover the dish with foil to prevent the cheese from browning too much.
