A Modern Twist on a Classic Sandwich
The Philly cheesesteak has long been a staple in American comfort food, originating from Philadelphia in the early 20th century. Traditionally made with thinly sliced steak, onions, peppers, and melted cheese served in a hoagie roll, it’s known for its bold flavors and crave-worthy appeal.
This casserole version is a modern twist that delivers all those same flavors but skips the bread, making it more suitable for gluten-free, low-carb, and keto diets. Instead of being confined to a sandwich, these savory ingredients are combined in a creamy, cheesy mixture and baked into a bubbling, golden casserole that’s comforting and satisfying.

The Flavor Breakdown
Each bite of this casserole delivers a layered flavor experience. The beef is browned to perfection and seasoned with just the right touch of Worcestershire sauce, garlic, salt, and pepper to enhance its savory depth. Bell peppers add sweetness and crunch, while the onions bring their signature mellow bite once cooked down.
The creamy base made from cream cheese, sour cream, and a bit of mayonnaise helps bind everything together while adding richness and body.

- Switch Up the Protein: Use thinly sliced steak for a more traditional take or even ground turkey or chicken for a leaner option.
