Let’s Get Cooking! Your Step-by-Step Guide
Ready to create the cheesiest, most satisfying casserole ever? Let’s get started.
Part 1: The Savory Philly Filling
- Preheat and Prep: First, preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with non-stick spray.
- Sauté the Veggies: Heat the olive oil in a large skillet over medium heat. Add the diced onions and bell peppers and cook, stirring occasionally, for 5-6 minutes until they start to soften. Add the minced garlic and cook for another 30 seconds until fragrant.
- Brown the Beef: Add the ground beef to the skillet with the vegetables. Use a spatula to break it up as it cooks. Season generously with salt and pepper and cook for 7-8 minutes, until it’s completely browned with no pink remaining. Drain off any excess fat.
Part 2: Create the Creamy Base and Assemble
- Add the Flavor: Stir the Worcestershire sauce into the meat mixture. Reduce the heat to low.
- Make it Creamy: Add the softened cream cheese to the skillet, stirring until it’s completely melted and has created a rich, creamy sauce that coats all the meat and vegetables.
- Assemble the Casserole: Transfer this entire mixture to your prepared 9×13 baking dish and spread it into an even layer.
- Top with Cheese: Layer the slices of provolone cheese evenly over the top of the beef mixture. Finally, sprinkle the shredded mozzarella over the provolone.
Part 3: Bake to Bubbly Perfection
- Bake: Place the dish in the preheated oven and bake for 22-25 minutes.
- Golden and Bubbly: The casserole is done when all the cheese is completely melted, bubbly, and just starting to turn a beautiful golden brown on top.
- Rest and Serve: Let the casserole rest for at least 5 minutes before serving. This allows it to set up and makes it easier to serve. Enjoy!

Notes
WiseRecipes’ Top Tips for Casserole Success
These simple secrets will ensure your Philly Cheesesteak Casserole is a home run.
- Drain the Fat. After browning your ground beef, be sure to drain off any excess grease. This prevents the final casserole from being oily and lets the creamy cheese sauce shine.
- Room Temperature Cream Cheese is a MUST. For the creamiest, smoothest sauce with no lumps, your cream cheese must be fully softened before you add it to the hot skillet.
- Don’t Be Shy with the Provolone. Provolone is the classic cheese on a Philly cheesesteak, and its sharp, slightly salty flavor is key to the authentic taste of this dish. Don’t skimp on it!
- Let It Rest! That 5-minute rest after it comes out of the oven is crucial. It allows the creamy filling and melted cheese to set up just enough, so you can scoop out beautiful portions instead of a runny mess.
- Freshly Shredded Cheese is Best. While pre-shredded mozzarella is convenient, shredding your own from a block will result in a smoother, meltier, and more glorious cheese topping because it doesn’t have the anti-caking starches.
Keep It Fresh! Storing & Reheating Instructions
This casserole is a meal-prepper’s dream. Here’s how to store it for delicious leftovers.
- Refrigerator: Once cooled, cover the baking dish tightly with foil or transfer individual portions to airtight containers. The casserole will stay delicious in the refrigerator for up to 4 days.
- Freezer: This casserole also freezes well! You can freeze the entire dish or individual portions in freezer-safe containers for up to 3 months. Let it thaw in the refrigerator overnight before reheating.
- Reheating: The best way to reheat is in the oven at 350°F until warmed through. You can also easily reheat individual portions in the microwave.
FAQs: Your Cheesesteak Casserole Questions, Answered!
