What Is Philly Cheesesteak Casserole?
Philly Cheesesteak Casserole is a baked dinner inspired by the famous Philadelphia cheesesteak sandwich.
Instead of piling thinly sliced beef, onions, peppers, and cheese onto a long roll, we're turning those same flavors into a warm, bubbling casserole.
Depending on the version, cheesesteak casserole can be made with pasta, rice, potatoes, or simply a beef-and-vegetable filling.
This version keeps things simple with tender ground beef, sautéed vegetables, pasta, and plenty of melted cheese.
It's hearty, creamy, cheesy, and incredibly satisfying.

What Does Philly Cheesesteak Casserole Taste Like?
The flavor is savory, cheesy, slightly sweet, and wonderfully beefy.
The browned beef gives the casserole its hearty base, while sautéed onions and bell peppers add sweetness and a little texture.
The pasta soaks up all those delicious juices, and the cheese melts into everything.
It's very much like eating the filling of a cheesesteak—but with a comforting casserole twist.
