Philly Cheesesteak Casserole brings you everything you love about the iconic sandwich in one easy, oven-baked dish. You still get juicy beef, sautéed peppers and onions, and plenty of melted cheese. However, you skip the bread, the griddle, and the mess. Instead, you bake everything together in a hearty casserole that slices beautifully and feeds a crowd with ease.
This recipe works perfectly for busy weeknights. At the same time, it shines at game day parties and potlucks. Because you prepare it in one pan, cleanup stays simple. Even better, the flavors blend together in the oven, creating a rich, savory bite in every forkful.
I first made this Philly Cheesesteak Casserole on a cold Sunday when I craved comfort food but did not want to stand over the stove flipping sandwiches. I had ground beef in the fridge and plenty of cheese, so I decided to layer everything in a baking dish. The aroma filled the kitchen while it baked, and my family hovered nearby waiting to dig in. Since then, this dish has become our go-to for casual gatherings and cozy nights at home.
Why You’ll Love This Philly Cheesesteak Casserole
Classic Flavor Without the Bread
Philly Cheesesteak Casserole delivers the bold, savory taste of the traditional sandwich, yet it skips the roll entirely. As a result, you get all the juicy beef and melty cheese without worrying about soggy bread or assembling individual sandwiches.
The combination of ground beef, sautéed onions, and bell peppers creates that unmistakable cheesesteak flavor. Meanwhile, Worcestershire sauce deepens the savory notes and adds a subtle tang. Because everything bakes together, the flavors blend beautifully.
Additionally, the creamy layer of melted cream cheese makes every bite rich and satisfying. Then the shredded mozzarella and provolone melt into a golden, bubbly topping. Each forkful feels indulgent but still simple and comforting.
Perfect for Busy Nights and Gatherings
This Philly Cheesesteak Casserole fits into almost any schedule. First, you brown the beef and sauté the vegetables. Then you stir in the cream cheese, layer the cheeses, pour over the egg mixture, and bake. The oven handles the rest.
Because the recipe uses common pantry ingredients, you can prepare it without a special trip to the store. Moreover, the 9×13-inch dish serves a crowd, which makes it ideal for potlucks or family dinners.
You can also prepare the beef mixture ahead of time. When you feel ready to bake, simply assemble and pop it in the oven. Therefore, you save time while still serving a warm, homemade meal.
Ingredients That Make It Irresistible
The Savory Beef and Vegetable Base
The foundation of this Philly Cheesesteak Casserole starts with two pounds of ground beef. You can also use thinly sliced steak if you prefer a more traditional texture. Either option works well because the seasoning ties everything together.
Next, diced onion and both green and red bell peppers add sweetness and color. As they cook, they soften and release their natural flavors. Garlic brings depth, while Worcestershire sauce enhances the savory profile.
Salt and black pepper balance everything. Although the seasoning list stays simple, the flavors build naturally as the ingredients cook together. Because you sauté the vegetables with the beef, every bite tastes cohesive.
The Creamy, Cheesy Layers
Once you stir in softened cream cheese, the mixture becomes creamy and rich. This step transforms the filling from a simple beef skillet into something truly comforting. The cream cheese melts directly into the meat, coating it evenly.
After you spread the mixture into your baking dish, shredded mozzarella and provolone create that signature cheesy topping. Mozzarella melts smoothly, while provolone adds a slightly sharper flavor. If needed, you can use all mozzarella, and the casserole will still turn out delicious.
Finally, the whisked eggs and heavy cream form a light custard that sets during baking. This layer helps hold the casserole together and gives it structure without making it heavy.

Notes
Step-by-Step Guide to Perfect Results
Cooking the Beef and Vegetables
Start by preheating your oven to 350°F. While it heats, lightly grease a 9×13-inch baking dish so nothing sticks.
In a large skillet over medium heat, cook the ground beef until browned. Break it apart as it cooks so it crumbles evenly. Once fully cooked, drain any excess grease. This step prevents the casserole from becoming too oily.
Next, add the diced onion and peppers to the skillet. Cook them for about 4 to 5 minutes until they soften. Then stir in the minced garlic, Worcestershire sauce, salt, and black pepper. Let everything cook for one additional minute to develop flavor.
Reduce the heat to low. Stir in the softened cream cheese and mix until fully melted and combined. The mixture should look creamy and cohesive.
Assembling and Baking the Casserole
Spread the beef mixture evenly into the prepared baking dish. Make sure it forms an even layer so it bakes consistently.
Sprinkle the shredded mozzarella and provolone over the top. Cover the surface evenly so every slice gets plenty of cheese.
In a small bowl, whisk together the eggs and heavy cream until smooth. Pour this mixture evenly over the casserole. It will seep down into the layers and help everything set.
Bake for 20 to 25 minutes. The cheese should melt and bubble, and the center should feel set when lightly pressed. After baking, let the casserole rest for five minutes. This short wait makes slicing easier and keeps the layers intact.
Tips, Variations, and Serving Ideas
Easy Customizations
Although this Philly Cheesesteak Casserole tastes amazing as written, you can easily customize it. For example, you can swap ground beef for thinly sliced sirloin to mimic the classic sandwich even more closely.
If you enjoy a little heat, add sliced jalapeños or a pinch of crushed red pepper flakes. You can also mix in mushrooms for extra texture and flavor.
For a lighter version, use reduced-fat cream cheese and part-skim mozzarella. The casserole will still turn out creamy and satisfying.
How to Serve and Store
Serve Philly Cheesesteak Casserole warm, straight from the oven. It pairs well with a simple green salad or roasted vegetables. Because the dish feels hearty on its own, you do not need many sides.
If you have leftovers, store them in an airtight container in the refrigerator for up to four days. Reheat individual portions in the microwave or warm larger portions in the oven at 325°F until heated through.
You can also freeze this casserole. First, let it cool completely. Then wrap it tightly and freeze for up to two months. Thaw overnight in the refrigerator before reheating. As a result, you always have a comforting meal ready to go.
