Origin and Cultural Significance

The legendary Philly cheesesteak originated in Philadelphia in the 1930s, credited to Pat Olivieri — the creator of the first steak sandwich stand. Over time, it evolved into a cultural symbol of the city, beloved for its simplicity and savory goodness.
Transforming the sandwich into a casserole maintains the cherished flavors of East Coast tradition while adapting the meal into a more accessible, shareable dish for modern kitchens.

Ingredients & Quantity

Yields: 6–8 servings
Prep Time: 20 minutes
Cook Time: 25–30 minutes

For the Casserole:

  • 1 ½ lbs ribeye steak, thinly sliced
    (or substitute sirloin, flank steak, or shaved beef)
  • 2 tablespoons olive oil, divided
  • 1 large yellow onion, thinly sliced
  • 1 large green bell pepper, thinly sliced
  • 1 large red bell pepper, thinly sliced
  • 8 oz mushrooms, sliced (optional but classic)
  • 3 cloves garlic, minced
  • 8 oz cream cheese, softened
  • 1 cup heavy cream or whole milk
  • 2 cups provolone cheese, shredded
  • 2 cups mozzarella cheese, shredded
  • 4 cups cubed French bread or hoagie rolls
  • Salt and black pepper, to taste
  • 1 teaspoon Worcestershire sauce (optional)

Optional Additions

  • Hot banana peppers for tangy heat
  • Swiss cheese in place of provolone
  • Steak seasoning or smoked paprika
  • Sliced jalapeños for spice
  • Fresh parsley for garnish

Tips for Success

  • Flash freeze meat 15 minutes before slicing for cleaner strips
  • Don’t overcook the steak — it continues cooking in the oven
  • Toast bread cubes slightly first to prevent sogginess
  • Use freshly shredded cheese for a smoother melt
  • Taste and adjust seasoning after sautéing vegetables

Instructions

  1. Prepare Oven
    Preheat to 375°F (190°C). Grease a 9×13 casserole dish.

  3. Sauté Veggies
    In the same skillet, add remaining oil.
    Cook onions, peppers, and mushrooms until soft. Stir in garlic and cook for 1 minute.
  4. Cheese Sauce
    Reduce heat. Add cream cheese and heavy cream, stirring until smooth.
    Mix in Worcestershire sauce if using.
  5. Combine
    Add beef back into the skillet with half of the provolone and mozzarella.
  6. Assemble Casserole
    Place bread cubes into prepared dish.
    Pour the beef and cheese mixture evenly over the top.
    Sprinkle remaining cheese over everything.
  7. Bake
    Bake uncovered for 20–25 minutes or until bubbly and golden.
  8. Serve
    Let rest 5 minutes before cutting. Garnish if desired.
