Why This Philly Cheesesteak Casserole Recipe Works
This Philly Cheesesteak Casserole works so well because it stays true to the flavors that made the original sandwich famous while adapting them into a baked format that enhances texture and taste.
First, thinly sliced roast beef is key. It heats quickly without drying out, remaining tender and juicy throughout the baking process. When paired with sautéed onions and green bell peppers, the beef absorbs their sweetness and depth, creating a perfectly balanced filling.
Second, provolone cheese plays a starring role. Its mild, creamy flavor melts smoothly and evenly, forming that irresistible cheesy layer on top. Provolone is traditional for Philly cheesesteaks, and using it here keeps the dish authentic.
The addition of beef broth and Worcestershire sauce adds moisture and umami richness. These ingredients prevent the casserole from becoming dry and elevate the flavor profile without overpowering the beef.
Finally, baking everything together allows the flavors to meld into a cohesive, comforting dish. That’s why Philly Cheesesteak Casserole is so reliable, satisfying, and crowd-pleasing.
