Ingredients

  • 500 g thinly sliced beef steak
  • 1 large green bell pepper, chopped
  • 1 medium onion, sliced
  • 2 cups shredded mozzarella or provolone cheese
  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • 3 cloves garlic, minced
  • 200 g mushrooms, sliced (optional)
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon Italian seasoning
  • ½ teaspoon smoked paprika
  • ½ teaspoon black pepper
  • 1 teaspoon salt (or to taste)
  • 120 ml beef broth
  • 120 ml heavy cream
  • 120 g cream cheese, softened
  • Fresh parsley, chopped (for garnish)

Instructions

Step 1: Prepare the Beef

Season the thinly sliced beef with salt, pepper, smoked paprika, and Italian seasoning.

Step 2: Cook the Vegetables

Heat the butter and olive oil in a large skillet over medium-high heat. Add the onions and bell peppers and cook for about 5 minutes until softened. Stir in the garlic and mushrooms, cooking for another 3–4 minutes.

Step 3: Brown the Beef

Add the seasoned beef to the skillet. Cook for 4–5 minutes until browned, then stir in the Worcestershire sauce.

Step 4: Make the Creamy Sauce

Reduce the heat to medium. Add the cream cheese, heavy cream, and beef broth. Stir continuously until the cream cheese melts and the sauce becomes smooth and creamy.

Step 5: Assemble the Casserole

Preheat the oven to 190°C (375°F). Transfer the beef mixture into a greased 9×13-inch baking dish. Sprinkle the shredded mozzarella or provolone cheese evenly over the top.

Step 6: Bake

Bake for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden.

Step 7: Serve

Allow the casserole to rest for 5 minutes before serving. Garnish with fresh parsley and enjoy.

Cooking Methods

Skillet and Oven Method

Cook the filling in a skillet, transfer it to a baking dish, top with cheese, and bake until golden.

One-Pan Method

Use an oven-safe skillet. After preparing the filling, simply top with cheese and place the skillet directly in the oven.

Slow Cooker Method

Cook the vegetables and beef first, then transfer everything to a slow cooker. Add the creamy ingredients and cook on low for 2–3 hours. Add the cheese during the last 20 minutes.

The History of Philly Cheesesteak

The original Philly cheesesteak was created in Philadelphia, Pennsylvania, during the 1930s by hot dog vendor Pat Olivieri. He grilled thin slices of beef and served them in a long roll, creating a sandwich that quickly became famous. Cheese was added later, making the cheesesteak one of America’s most beloved comfort foods. This casserole transforms those iconic flavors into an easy baked dish that’s perfect for sharing.
