How to Make Philly Cheesesteak Casserole
Step 1: Sauté the Beef and Vegetables
In a large skillet, cook the ground beef over medium-high heat.
Once browned, drain excess fat.
Add onions, peppers, and garlic.
Cook until softened and fragrant.
Season with salt, pepper, and paprika.
Step 2: Create the Creamy Cheesesteak Sauce
Reduce heat to medium.
Stir in the cream cheese until melted and smooth.
Add heavy cream (or milk) and Worcestershire sauce.
Simmer gently until the mixture thickens slightly and becomes rich and creamy.
This sauce becomes the heart of the casserole—savory, silky, and packed with flavor.
Step 3: Assemble the Casserole
Transfer the beef mixture into a greased baking dish.
If you’re using cooked pasta or noodles, fold them in now for a more filling, layered dish.
Top generously with shredded mozzarella or provolone.
Add extra diced peppers on top for color and texture.
Step 4: Bake Until Golden
Bake at 375°F (190°C) for 20–25 minutes, or until the cheese is melted, bubbly, and lightly browned around the edges—just like the picture.
Allow the casserole to rest for 5–10 minutes to set before serving.
Serving Ideas
Pair this casserole with:
-
Garlic bread
-
A crisp green salad

Roasted vegetables

It also makes fantastic leftovers—try it in a wrap or spooned over toasted bread for a cheesesteak-style open-faced sandwich.
