Ingredients
- 1 lb thinly sliced sirloin steak
The star ingredient, sirloin steak, provides a rich and meaty base for the casserole. Its tender texture absorbs flavors beautifully, ensuring that each bite is juicy and satisfying. - 1 cup diced onions
Onions add sweetness and depth to the dish. When sautéed, they soften and caramelize, contributing to the overall flavor profile that defines a traditional Philly cheesesteak. - 1 cup diced bell peppers (red & green)
Bell peppers bring a vibrant color and slight crunch to the casserole. They also add a fresh, sweet taste that balances the richness of the meat and cheese. - 4 cups frozen potato tots
These provide a crispy, golden topping that contrasts pleasantly with the tender filling. Their texture helps to create a deliciously inviting casserole crust. - 2 cups provolone cheese, shredded
Provolone cheese melts beautifully and has a mild flavor that complements the other ingredients. It binds the casserole together and elevates the overall cheesiness, essential for a Philly cheesesteak. - 1 cup beef broth
Beef broth enhances the meatiness of the dish and prevents it from drying out during baking. It enriches the filling, making each forkful succulent and flavorful. - 1 tablespoon Worcestershire sauce
This sauce adds an umami punch and a hint of tanginess, elevating the savory elements of the casserole. It complements the beef well, rounding out the overall taste. - 1 teaspoon garlic powder
Garlic powder adds an aromatic note that enhances the dish's flavor without overpowering it. It works well with the other ingredients to create a well-rounded profile. - 1 teaspoon black pepper
Freshly cracked black pepper provides heat and depth. It accentuates the flavors of the steak and complements the savory elements presented by the cheese and broth.
Directions & Preparation
Step 1: Preheat your oven to 400°F (200°C).
Starting with a preheated oven ensures that the casserole cooks evenly from the moment it enters. This step is crucial for achieving a golden and crispy topping, making each serving visually appealing and delicious.
Step 2: In a large skillet over medium heat, sauté the onions and bell peppers until softened, about 5 minutes.
Sautéing the onions and bell peppers beforehand enhances their sweetness and allows them to caramelize slightly. This not only amplifies their flavor but also helps integrate them more effectively into the casserole.
Step 3: Add the sliced sirloin steak to the skillet and cook until browned, about 4-5 minutes.
Browning the beef adds depth of flavor through the Maillard reaction while sealing in the juices. This step is critical to preventing the beef from becoming grey and lifeless in the casserole.
Step 4: Stir in the garlic powder, Worcestershire sauce, black pepper, and beef broth, simmer for another 2-3 minutes.
This simmering step allows the flavors to meld and infuses the beef with moisture from the broth. It creates a well-seasoned filling that’s both savory and aromatic, essential for a great casserole.
Step 5: Spread the beef mixture evenly into a greased baking dish.
Layering the beef mixture evenly ensures that every bite has a balanced proportion of meat and vegetables. This also helps the casserole cook uniformly, preventing any undercooked or overcooked sections.
Step 6: Top the beef mixture with frozen potato tots, arranging them in a single layer.
Arranging the potato tots in a single layer helps them crisp up nicely during baking. This step allows them to brown evenly, developing a crunchy texture that complements the soft filling.
Step 7: Sprinkle the shredded provolone cheese generously over the potato tots.
Adding cheese to the top not only enhances the flavor but also gives a beautifully melted and gooey finish. The cheese acts as a delicious binding layer, ensuring each bite is rich and fulfilling.
Step 8: Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and the tots are golden brown.
Baking until golden ensures that the casserole achieves a satisfying texture and appearance. The bubbly cheese indicates that it's perfectly melted, while golden tots signal a crisp, delightful crunch.
Step 9: Remove from the oven and let it cool for 5-10 minutes before serving.
Allowing the casserole to rest gives it time to set, making it easier to serve without falling apart. This step is crucial for preserving the layers and ensuring a beautiful presentation.

Customize Your Cheese Experience
While provolone is a classic choice for a Philly cheesesteak casserole, you can easily switch it up. Combining different cheeses, such as melted mozzarella, sharp cheddar, or even creamy gouda, can enhance flavor and texture. Experimenting with a mix can lead to delightful surprises that perfectly complement the savory beef and veggies.
Additions and Substitutions for Variety
You can personalize your casserole by adding extra ingredients such as sautéed mushrooms or jalapeños for a kick of heat. For those looking for a heftier dish, consider incorporating cooked pasta or quinoa to create a more filling meal that still captures all the classic cheesesteak flavors.
Serving and Pairing Suggestions
This casserole pairs wonderfully with side salads or garlic bread, which can cut through the richness of the dish. A light, tangy salad like a simple arugula or Caesar salad complements the flavors while providing a refreshing contrast to the decadent casserole.
FAQs
What if the casserole is too thick or dry?
If your casserole turns out too thick or dry, you can add a splash of beef broth and mix it gently before serving. This adds moisture and enhances flavor without compromising the dish.
Can I add different vegetables to the casserole?
Yes, you can incorporate various vegetables, such as mushrooms or zucchini, to add unique flavors and textures. Just ensure they are prepared beforehand to avoid excess moisture.
How can I adjust the recipe to serve a larger group?
To scale the recipe, simply double or triple the quantities of each ingredient, ensuring to use a larger baking dish. Adjust the baking time as necessary, keeping an eye on the cheese to ensure it melts properly.
What should I do if I used too much Worcestershire sauce?
If the casserole tastes too salty from excess Worcestershire sauce, you might consider adding a bit more beef broth to balance the flavors and diluted the saltiness.
Can I use a different type of meat?
Absolutely, feel free to substitute the sirloin with chicken or turkey for a lighter version of the casserole. Just ensure the meat is cooked thoroughly before layering.
What can I do to make the casserole spicier?
To add heat, consider mixing in some diced jalapeños or a pinch of red pepper flakes into the beef mixture. This can elevate the flavor profile to suit those who enjoy a bit of spice.
