If you love a good Philly cheesesteak but don’t always feel like standing over the stove, this Philly Cheesesteak Casserole is going to be a new favorite at your table. It has all the classic flavors you crave—tender beef, sautéed peppers and onions, and plenty of melty cheese—baked together in one cozy, family-style dish.
I love making this on busy weeknights when everyone is coming home at different times. You can get everything layered in the baking dish, slide it into the oven, and let it bubble away while you set the table or finish up the day. By the time it comes out, the kitchen smells like a cheesesteak shop in the best way, and nobody has to wait long for a warm, cheesy plate of comfort.
There’s always this little moment right before we dig in—someone pulls out the first slice and you see the cheese stretch, the toasted edges, and the colorful peppers tucked inside. It’s the kind of dish that makes the whole table go quiet for a second… and then everyone starts asking for seconds.

The top gets just a little golden and bubbly, while the inside stays creamy and rich. Every bite has that perfect mix of beef, veggies, and cheese—comforting, satisfying, and just messy enough to feel like the real deal.

Instructions
Preparation
- Heat the oven to 375°F and lightly grease a 9×13 baking dish.
- Warm the olive oil in a large skillet over medium-high heat. Add the onion and peppers, cooking until softened and fragrant, about 6 to 8 minutes.
- Stir in the mushrooms and cook for an additional 3 minutes. Add garlic for the last 30 seconds of cooking to avoid burning it.
- Push the vegetables to the edges of the skillet, add the beef in a single layer, and sprinkle with salt, pepper, paprika, and Italian seasoning. Sear for 1-2 minutes per side until pink fades.
- In a bowl, whisk together milk and cornstarch until smooth, then stir in cream cheese until creamy.
- Pour the milk mixture over the steak and vegetables in the skillet; it will thicken while baking.
- If desired, fold in cooked noodles or rice, then taste and adjust seasoning.
- Transfer the mixture into the prepared baking dish, top with provolone and cheddar cheese.
- Bake for 15-18 minutes until the cheese is bubbling and golden at the edges. Let rest for 5 minutes before slicing.
- Garnish with fresh parsley before serving.
