🧂 Ingredients
For the Beef Mixture
- 1 lb ground beef (or thinly sliced steak for authenticity)
- 1 tbsp olive oil
- 1 small onion, thinly sliced
- 1 green bell pepper, thinly sliced
- 1/2 cup mushrooms, sliced (optional but traditional)
- 2 cloves garlic, minced
- 1 tbsp Worcestershire sauce
- Salt and black pepper, to taste
For the Creamy Base
- 4 oz cream cheese, softened
- 1/4 cup heavy cream
- 1/4 cup beef broth
- 1 tsp Dijon mustard
For the Topping
- 1 1/2 cups shredded provolone cheese (or mozzarella)
- 1/2 cup shredded cheddar cheese
- Fresh parsley, chopped (for garnish) 🌿

👩🍳 Step-by-Step Directions
- Preheat the oven to 375°F (190°C). Grease a medium casserole dish with a little olive oil or butter.
- Cook the beef: In a large skillet, heat olive oil over medium-high heat. Add the ground beef and cook until browned, breaking it apart with a spatula. Drain excess fat if needed.
- Add the veggies: Stir in the onions, peppers, mushrooms, and garlic. Sauté for 5–6 minutes until the vegetables are tender and aromatic.
- Season it up: Add Worcestershire sauce, salt, and black pepper. Give everything a good stir so the flavors blend beautifully.
- Make the creamy sauce: In a small bowl, whisk together cream cheese, heavy cream, beef broth, and Dijon mustard until smooth. Pour this luscious mixture over the beef and veggies in the skillet. Stir until everything is coated evenly.
- Assemble the casserole: Transfer the beef mixture into the prepared baking dish. Spread it out evenly.
- Add the cheese: Sprinkle the provolone and cheddar cheese evenly on top.
- Bake it to perfection: Bake uncovered for about 20 minutes, or until the cheese is melted and bubbly with golden edges.
- Garnish and serve: Let it cool for 5 minutes, sprinkle with chopped parsley, and serve warm. 🧀
💡 Tip: For a true Philly feel, serve it with sautéed mushrooms or a side of roasted cauliflower rice.
