Ingredients You’ll Need
1 lb ground beef or shaved steak
1 medium onion, chopped
1 green bell pepper, diced
1 red bell pepper, diced
2 cloves garlic, minced
1 cup mushrooms, sliced (optional)
8 oz cream cheese, softened
1/2 cup sour cream
1 cup shredded mozzarella cheese
1 cup provolone or white American cheese
8 oz cooked pasta or rice
Salt, pepper, and Worcestershire sauce
How to Make Philly Cheesesteak Casserole
Step 1: Prepare the Beef
In a large skillet, brown the ground beef (or shaved steak) over medium heat. Break it apart as it cooks until it’s fully browned and slightly crispy around the edges. Drain any excess fat and set aside.
Step 2: Sauté the Vegetables
In the same pan, add the chopped onion, green and red bell peppers, and mushrooms if using. Sauté for about 5 minutes, until tender and fragrant. Stir in minced garlic and cook for an additional minute. Add a splash of Worcestershire sauce for that signature steakhouse flavor.
Step 3: Combine the Filling
Return the cooked beef to the pan with the vegetables. Stir in the softened cream cheese and sour cream until everything blends into a smooth, creamy sauce. Season with salt and pepper to taste. Add the cooked pasta or rice, if desired, and mix until evenly coated.
Step 4: Assemble the Casserole
Transfer the mixture to a greased 9x13-inch baking dish. Sprinkle mozzarella and provolone cheeses evenly over the top. You can mix the cheeses for a richer, gooey topping.
Step 5: Bake to Perfection
Preheat your oven to 375°F (190°C). Bake uncovered for 20–25 minutes or until the cheese is melted, bubbly, and lightly golden on top. Let it rest for 5 minutes before serving so the flavors can settle beautifully.
Tips for the Perfect Philly Cheesesteak Casserole
Use thinly sliced ribeye steak for a truly authentic flavor if you want to elevate it.
Don’t skip the cream cheese — it’s what gives this casserole its creamy, velvety texture.
Want a spicy kick? Add chopped jalapeños or a pinch of red pepper flakes.
For a low-carb version, skip the pasta and serve it over roasted cauliflower or zucchini noodles.
Sprinkle with fresh parsley or chives before serving for a touch of freshness and color.
