Ingredients
- 1 pound thinly sliced beef (ribeye or sirloin)
The star of the casserole, thinly sliced beef provides rich flavor and protein, making it a filling base. Ribeye adds a bit of fat for succulence, while sirloin is leaner but still delicious. - 2 cups bell peppers (sliced)
Bell peppers contribute vibrant color and a sweet crunch, enhancing the dish's texture. They also add vitamins A and C, providing a nutritional boost. - 1 cup onion (sliced)
Onions build a savory foundation for the casserole, caramelizing to create depth of flavor. Their natural sweetness complements the beef and peppers beautifully. - 4 ounces cream cheese
Cream cheese adds a creamy richness that binds the flavors together. It also helps to create a satisfying mouthfeel, imitating the melted cheese in the original sandwich. - 1 cup shredded mozzarella cheese
Shredded mozzarella provides that essential gooeyness we expect from a cheesesteak, melting beautifully over the top for a comforting finish. - 1 tablespoon Worcestershire sauce
This sauce infuses umami flavor and complexity, mimicking the taste profile of traditional cheesesteaks. It adds a touch of savory depth that enhances the overall dish. - 1 teaspoon garlic powder
Garlic powder offers a convenient way to imbue the casserole with aroma and flavor without the hassle of chopping fresh garlic, enriching the savory notes. - Salt and pepper to taste
Essential seasonings that enhance all the other flavors in the casserole, ensuring a balanced and delicious dish.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C).
Preheating the oven ensures that your casserole cooks evenly and reaches the right temperature. This step is crucial for achieving a perfectly melted cheese topping and properly cooked beef.
Step 2: In a large skillet over medium-high heat, cook the sliced beef until browned, approximately 5-7 minutes.
Browning the beef imparts flavor and texture to the dish. Be sure to stir occasionally to cook evenly, and don’t overcrowd the skillet to ensure a proper sear.
Step 3: Add sliced onions and bell peppers to the skillet, cooking for an additional 5 minutes until softened.
This step builds on the flavor foundation established by the beef. The heat releases the natural sugars in the onions and peppers, enhancing their sweetness and melding them with the meat.
Step 4: Reduce heat and stir in cream cheese, Worcestershire sauce, garlic powder, salt, and pepper; mix until the cream cheese is completely melted.
Incorporating cream cheese into the mixture creates a creamy sauce that brings cohesion to the casserole. It’s important to mix thoroughly for a smooth consistency that coats all the ingredients.
Step 5: Transfer the beef and veggie mixture into a greased baking dish.
Choosing the right baking dish helps the casserole cook evenly. Greasing it prevents sticking and ensures easy cleanup, allowing for a hassle-free dining experience.
Step 6: Top the mixture with shredded mozzarella cheese evenly.
Sprinkling mozzarella on top creates a cheesy crust that’s essential for a comfort food dish. Be sure to cover the mixture generously for maximum meltiness and flavor.
Step 7: Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden.
Baking melds all the flavors together and gives the mozzarella a delicious golden crust. Keeping an eye on it during the final moments helps prevent over-browning.
Step 8: Allow the casserole to cool for 5 minutes before serving.
Letting the casserole rest slightly makes it easier to serve and allows the flavors to settle. This brief cooling period enhances the overall tasting experience.

Layering Flavors for Maximum Impact
To achieve the best flavor in your Low Carb Philly Cheesesteak Casserole, layering the ingredients thoughtfully is key. Starting with browning the beef ensures it builds a rich base flavor, while adding the vegetables after allows them to soften and integrate with the meat. Cream cheese binds the flavors and adds creaminess, while the mozzarella topping creates that iconic cheesesteak experience.
Creative Variations for a Personalized Dish
Feel free to make this casserole your own by incorporating your favorite vegetables or seasonings. For a spicy kick, consider adding jalapeños or a sprinkle of red pepper flakes. Alternatively, swapping out the beef for a protein like chicken or turkey can cater to different dietary needs while keeping the essence of the dish intact.
Serving Suggestions that Elevate Your Meal
While the casserole is hearty enough to stand on its own, consider pairing it with a fresh green salad or low-carb sides like roasted asparagus or zucchini noodles. These complements not only balance the richness of the casserole but also enhance the meal's visual appeal with contrast and color.
FAQs
Why is my casserole too thick?
If the casserole turns out thicker than desired, simply incorporate a splash of broth or water while mixing in the cream cheese to achieve a creamier consistency.
What can I do if the casserole tastes bland?
If your casserole lacks flavor, consider increasing the garlic powder, Worcestershire sauce, or adding some fresh herbs like parsley or basil for a fresh twist.
Can I make this casserole using ground beef instead of sliced beef?
Absolutely! Ground beef can be a great substitute, although it will create a different texture. Adjust the cooking time accordingly until it's fully browned.
How can I add more vegetables to the casserole?
You can add sautéed mushrooms or spinach for extra nutrients and flavor without significantly increasing the carb count, ensuring you maintain the dish's balance.
What if the cheese isn’t melting properly?
If the cheese does not melt as expected, ensure the oven is fully preheated before baking, and consider covering the dish with foil for the first half of cooking to trap moisture.
Can I use a different type of cheese for topping?
Yes, you can use cheeses like provolone or cheddar, but remember that different cheeses can alter the overall flavor profile, adding a unique twist to the dish.
