Philly Cheesesteak Casserole

Step 4: Build the Flavor

Return the cooked beef to the skillet with the vegetables. Add Worcestershire sauce and gently stir everything together. Taste and adjust seasoning with more salt or pepper if needed. Remove from heat.

Step 5: Add Creaminess

In a mixing bowl, combine cream cheese or sour cream until smooth. Stir this mixture into the beef and vegetable filling. This step gives the casserole its rich, creamy texture and helps bind everything together.

Step 6: Assemble the Casserole

Spread your cooked pasta, rice, or potatoes evenly in the prepared casserole dish. Spoon the cheesesteak mixture over the top and spread it out evenly.

Step 7: Layer the Cheese

Cover the casserole generously with provolone cheese. For extra cheesiness, add a layer of mozzarella or white American cheese on top.

Step 8: Bake to Perfection

Place the casserole in the preheated oven and bake for 25–30 minutes, or until the cheese is fully melted, bubbly, and lightly golden on top.

Step 9: Rest and Serve

Remove the casserole from the oven and let it rest for about 5 minutes. This helps it set and makes serving easier. Spoon onto plates and enjoy while hot.

Serving Suggestions

• Serve with a simple green salad to balance the richness
• Pair with garlic bread or dinner rolls
• Add hot sauce or pepper flakes for extra heat

Tips for Success

• Slice the beef very thin for tenderness
• Don’t overcook the steak—it will continue cooking in the oven
• Provolone gives the most authentic flavor, but feel free to mix cheeses
• This casserole can be assembled ahead and refrigerated until ready to bake
