What is the secret ingredient in Philly cheesesteak?

Many say the “secret” ingredient is the ultra-thinly sliced ribeye, which cooks quickly and absorbs flavor. Others insist the magic comes from the cheese, especially Cheez Whiz, for its creamy, melty texture. The combination of tender beef, caramelized onions, and perfectly melted cheese is what truly defines the iconic taste.

What kind of sauce goes with Philly cheesesteak?

Philly cheesesteaks traditionally skip heavy sauces and rely on melted cheese for creaminess.
