🥩 A Quick Look at the Philly Cheesesteak
The Philly cheesesteak originated in Philadelphia in the 1930s when Pat Olivieri, a hot dog vendor, decided to grill beef on his stand. Eventually, cheese was added, and the sandwich quickly became legendary. Traditionally, it’s made with thinly sliced ribeye, sautéed onions, and melted cheese (often Cheez Whiz, provolone, or American) served in a hoagie roll.
Over the years, chefs and home cooks have experimented with different versions, from quesadillas to stuffed peppers. The casserole version is a brilliant twist because it removes the bread and transforms the flavors into a hearty, cheesy bake. This makes it not only easier to make for a family but also naturally low-carb and gluten-free.
