Ingredients

1 lb flank steak, sliced thin
Flank steak provides robust flavor and tenderness when cooked properly, making it ideal for this dish. Its texture allows it to absorb the savory sauce and meld beautifully with the other ingredients.
1 medium onion, diced
Onions add sweetness and depth to the dish. When cooked, they caramelize slightly, enhancing the overall flavor profile of the casserole.
1 bell pepper, diced
Bell peppers contribute a crunch and vibrant color, as well as a slight sweetness. They balance the savory elements and add freshness to the dish.
2 cups mushrooms, sliced
Mushrooms add an earthy umami flavor and a meaty texture that complements the steak. They also help to absorb and distribute the delicious flavors of the sauce throughout the casserole.
3 cloves garlic, minced
Garlic imparts a lovely aroma and enhances the flavors of the other ingredients. It brings a touch of pungency that is essential in savory dishes.
1 cup beef broth
Beef broth serves as the flavorful base of the casserole, infusing moisture into the ingredients and adding an essential savory depth.
2 tablespoons Worcestershire sauce
This sauce adds a tangy richness and complex flavor that evokes the essence of a classic cheesesteak. It enhances the overall savory profile of the dish.
1 teaspoon Italian seasoning
Italian seasoning brings a medley of herbs that elevate the flavor complexity without overshadowing the main ingredients.
4 cups cooked pasta (penne or rigatoni)
The pasta acts as a sturdy foundation, soaking up the sauce while ensuring the casserole is hearty and satisfying. It also adds a comforting, familiar aspect to the dish.
2 cups provolone cheese, shredded
Provolone cheese provides a perfect melt and creaminess, essential for that decadent cheesesteak experience. It binds the ingredients together and adds the signature cheesy top layer.
1/2 cup grated Parmesan cheese
Parmesan cheese adds a sharpness and a hint of nuttiness, which complements the creamy provolone. It also helps achieve a beautifully browned and crisp topping.

Directions & Preparation

Step 1: Preheat your oven to 375°F (190°C).

Preheating the oven ensures that the casserole cooks evenly and thoroughly. This initial step is crucial for achieving that perfect bubbly cheese topping and a nicely cooked casserole middle.

Step 2: In a large skillet, prepare the flank steak over medium-high heat until browned.

Searing the steak locks in its juices and flavor. It’s important to cook it until just browned, as it will continue cooking in the oven. This step adds depth to the dish.

Step 3: Add onions, bell peppers, and mushrooms to the skillet, cooking until softened.

Sautéing the vegetables enhances their natural flavors, allowing them to meld with the steak. This step makes the veggies tender and flavorful, contributing to the overall balance of the dish.

Step 4: Stir in the garlic and cook for another minute until fragrant.

Cooking the garlic briefly releases its essential oils, enhancing the aromatic quality of the dish. Be careful not to burn it, as overcooked garlic can become bitter.

Step 5: Pour in the beef broth, Worcestershire sauce, and Italian seasoning; simmer for a few minutes.

Simmering helps combine the flavors, allowing the sauce to reduce slightly and intensify. This step creates a rich, cohesive flavor that absorbs into all the ingredients.

Step 6: Toss the cooked pasta into the mixture until well combined, then transfer to a greased baking dish.

Mixing the pasta with the filling ensures every bite is evenly coated with the savory sauce. Using a greased baking dish prevents sticking and allows for easier serving.

Step 7: Top the mixture with provolone and Parmesan cheese equally across the surface.

Layering the cheese on top creates a delicious golden crust when baked. Combining both provolone and Parmesan elevates the richness and flavor of the topping.

Step 8: Bake for 25-30 minutes until the cheese is melted and bubbly.

Baking gives the casserole a warm, comforting texture and a crispy cheese top. Keep an eye on it for that beautiful golden color and bubbling edges.

Step 9: Let it cool for a few minutes before serving; this allows the casserole to set slightly.

Cooling slightly helps the casserole hold its shape when serving. This step ensures a more presentable dish with defined layers and avoids burning your mouth with hot cheese.

Choosing the Right Cut of Beef

For the best flavor and texture in your Philly Cheese Steak Casserole, selecting the right cut of beef is crucial. While flank steak is traditionally preferred for its tenderness, you can also use sirloin or ribeye for added marbling and flavor. Each cut offers a unique taste, so consider your preferences, or even mix different cuts for a rich flavor profile.

Enhancing Flavor with Cheese

The choice of cheese can dramatically affect the outcome of your casserole. Provolone is a classic, but feel free to experiment with other melty cheeses like mozzarella or Gouda for a different flavor twist. Combining cheeses can add depth; for instance, a sharp cheddar can introduce a delightful bite, while a creamy cheese achieves a superb melt.

Customizing Vegetables for Varied Flavors

The beauty of casserole dishes lies in their flexibility. While onions, bell peppers, and mushrooms are traditional, incorporating additional vegetables like zucchini, spinach, or roasted red peppers can elevate your dish. Each vegetable you add will bring a new flavor dimension to the casserole, making it uniquely yours.
