Ingredients

Scale

Meat and Vegetables

  • 1 lb (450g) ground beef (or shaved steak)
  • 1 tbsp olive oil
  • 1 medium onion, diced
  • 1 green bell pepper, diced
  • 1 red bell pepper, diced
  • 8 oz (225g) white mushrooms, sliced
  • 2 cloves garlic, minced

Seasoning and Sauces

  • 1 tsp salt (adjust to taste)
  • ½ tsp black pepper
  • 1 tsp Worcestershire sauce

Cheeses and Liquids

  • 8 oz (225g) cream cheese, softened
  • ½ cup (120ml) beef broth
  • 1 cup (115g) shredded mozzarella cheese
  • 1 cup (115g) shredded provolone cheese
  • ½ tsp dried oregano

Optional Garnish

  • Chopped parsley for garnish

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to ensure it is ready to bake the casserole when you finish assembling it.
  2. Brown Beef: In a large skillet over medium-high heat, add the olive oil and cook the ground beef until browned, breaking it apart with a spatula as it cooks. Drain excess fat if necessary to keep the casserole from being greasy.
  3. Sauté Vegetables: Add the diced onion, green and red bell peppers, and sliced mushrooms to the skillet with the beef. Sauté for 5 to 6 minutes until the vegetables are softened and aromatic. Stir in minced garlic and cook for an additional minute to develop flavor.
  4. Season and Simmer: Stir in salt, black pepper, Worcestershire sauce, and beef broth. Allow the mixture to simmer gently for 2 to 3 minutes to combine flavors and slightly reduce the liquid.
  5. Add Cream Cheese: Lower the heat and stir in the softened cream cheese until it melts smoothly into the meat and vegetable mixture, creating a creamy consistency.
  6. Assemble Casserole: Transfer the creamy beef and vegetable mixture into a lightly greased 9×13-inch baking dish, spreading it evenly.
  7. Top with Cheese and Herbs: Evenly sprinkle shredded mozzarella, provolone cheeses, and dried oregano over the top of the casserole.
  8. Bake: Place the casserole in the preheated oven and bake uncovered for 15 to 20 minutes, or until the cheese on top is melted, bubbly, and slightly golden.
  9. Garnish and Serve: Remove from oven, garnish with chopped parsley if desired, and serve hot. This casserole pairs well with crusty bread, rice, or a side salad.

Notes

  • You can substitute ground beef with shaved steak for a more traditional Philly cheesesteak texture.
  • Adjust salt and pepper seasoning according to taste preferences.
  • For a spicier kick, consider adding sliced jalapeños or a dash of hot sauce when sautéing vegetables.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
  • To keep the casserole gluten-free, verify Worcestershire sauce ingredients or substitute with a gluten-free alternative.
