What Is Philly Cheesesteak Casserole?
Philly Cheesesteak Casserole is inspired by the famous Philadelphia cheesesteak sandwich, traditionally made with thinly sliced beef, sautéed onions, and melted cheese served on a hoagie roll. In casserole form, these ingredients are layered or combined in a baking dish and baked until hot, bubbly, and golden.
Many versions include cream cheese or heavy cream to create a richer texture, while others add mushrooms or additional vegetables for extra flavor. This flexibility makes the casserole easy to customize according to personal preferences.

How to Make Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish and set it aside.
Step 2: Cook the Beef
Heat olive oil in a large skillet over medium-high heat.
Add the ground beef or sliced steak and cook until browned and fully cooked.
If using ground beef, break it apart as it cooks.
Drain excess grease if necessary.
Step 3: Sauté the Vegetables
Add the sliced onions, bell peppers, and mushrooms to the skillet.
Cook for approximately 5 to 7 minutes, stirring occasionally, until the vegetables become tender.
Add the minced garlic and cook for another minute until fragrant.
Step 4: Add the Creamy Ingredients
Reduce the heat to medium-low.
Add the softened cream cheese, heavy cream, Worcestershire sauce, Italian seasoning, salt, and pepper.
Stir continuously until the cream cheese melts and forms a smooth, creamy sauce that coats the beef and vegetables.
Step 5: Assemble the Casserole
Transfer the beef mixture into the prepared baking dish.
Spread it evenly across the bottom.
Layer the provolone cheese slices over the top and sprinkle with shredded mozzarella cheese.
The cheese layer will melt into a golden, bubbly topping during baking.
Step 6: Bake
Place the casserole in the preheated oven.
Bake for 20 to 25 minutes, or until the cheese is fully melted and lightly golden around the edges.
Step 7: Rest and Serve
Remove the casserole from the oven and allow it to rest for about 5 minutes.
Garnish with parsley or red pepper flakes if desired.
Serve hot and enjoy.
Tips for the Best Philly Cheesesteak Casserole
Use Quality Beef
Thinly sliced ribeye steak provides the most authentic cheesesteak flavor, though ground beef works well for convenience and affordability.
Don’t Overcook the Vegetables
The onions and peppers should remain slightly tender to maintain their texture and flavor.
Soften the Cream Cheese First
Room-temperature cream cheese blends more easily into the sauce, creating a smoother consistency.
Choose the Right Cheese
Provolone is traditional for Philly cheesesteaks, but mozzarella adds extra meltiness and richness.
