The classic cheeses for a Philly cheesesteak are provolone , American cheese, and Cheez Whiz, with provolone and Cheez Whiz usually treated as the “most traditional” picks.

Quick Scoop

  • Provolone (usually mild, not aged) is the go-to for many shops and home recipes because it melts smoothly and has a gentle, slightly tangy flavor.
  • Cheez Whiz is the iconic fast-service option in Philadelphia, ladled on hot and gooey; many locals see “wiz” as the classic late‑night cheesesteak cheese.
  • White American cheese is also very common, especially in modern shops, because it’s creamy, salty, and melts into the meat without stringiness.
  • Some newer or regional spots use sharp American or Cooper Sharp for a more pronounced bite while still melting well.

Mini breakdown: which to choose?

  • Want “old‑school shop” vibes at home: use mild provolone slices over the steak and onions, then cover and let it melt before loading the roll.
  • Want messy, drippy, late‑night energy: warm Cheez Whiz separately and spoon or drizzle it onto the filled roll.
  • Want super melty and kid‑friendly: white American cheese slices right on the meat until just melted.

If you’re not chasing strict authenticity, a mix of provolone and American (or a homemade “wiz” style sauce) gives you both stretch and creaminess in one sandwich.
