Ingredients & Their Purpose

• 1 pound Thinly Sliced Beef (ribeye or sirloin) – The star of the dish, delivering that signature cheesesteak flavor with juicy tenderness.
• 1 tablespoon Olive Oil – Helps brown the meat and soften the vegetables.
• 1 Large Onion (thinly sliced) – Adds subtle sweetness and depth, mimicking the Philly cheesesteak’s classic base.
• 1 Green Bell Pepper (thinly sliced) – Offers a fresh, slightly bitter crunch.
• 1 Red Bell Pepper (thinly sliced) – Brings vibrant color and a mild sweetness.
• 2 cloves Garlic (minced) – Boosts the overall aroma and flavor complexity.
• 1 teaspoon Salt – Enhances all the natural flavors.
• 1/2 teaspoon Black Pepper – Adds just the right kick without overpowering.
• 1 teaspoon Worcestershire Sauce – Deepens the umami and gives the beef a rich, savory edge.
• 1 cup Heavy Cream – Creates a luxurious sauce that binds everything together.
• 8 ounces Provolone Cheese (sliced) – A key Philly cheesesteak component, it melts beautifully into the dish.
• 1 cup Mozzarella Cheese (shredded) – Offers gooey, stretchy goodness on top.
• 4 cups Cooked Pasta (penne or rotini) – A sturdy base that soaks up all the flavor. Choose shapes that hold sauce well.
• 1/4 cup Parmesan Cheese (grated) – Adds a salty, nutty finish to the topping.
• 1 tablespoon Fresh Parsley (chopped) – Optional, but great for a pop of color and fresh finish.

Step-by-Step Instructions

1. Preheat oven to 375°F (190°C).
2. Cook the beef: Heat olive oil in a large skillet over medium-high heat. Add sliced beef and cook until browned, about 4-5 minutes. Remove from skillet and set aside.
3. Sauté the vegetables: In the same skillet, add onions and bell peppers. Sauté until soft, 5-7 minutes. Add garlic and cook 1 more minute until fragrant.
4. Combine beef and vegetables: Return beef to the skillet. Stir in salt, pepper, and Worcestershire sauce. Mix well to combine.
5. Make the sauce: Reduce heat to low. Pour in heavy cream and stir until fully combined and heated through. Let simmer for 2-3 minutes.
6. Mix with pasta and cheese: In a large bowl, combine cooked pasta, beef-veggie mixture, and sliced provolone cheese. Toss gently until evenly coated.
7. Assemble the casserole: Transfer the mixture to a greased 9×13-inch baking dish. Spread evenly.
8. Top with cheese: Sprinkle mozzarella and Parmesan cheese evenly over the top.
9. Bake: Bake for 20–25 minutes or until the cheese is melted, bubbly, and lightly golden on top.
10. Cool and garnish: Let sit for 5 minutes. Garnish with fresh parsley before serving, if desired.
