Ingredients
To create the best Keto Philly Cheesesteak Casserole, you need fresh, high-quality ingredients. While the original sandwich often uses ribeye steak, ground beef makes this casserole more affordable and easier to distribute evenly throughout the dish. We recommend an 80/20 fat ratio for the beef to ensure the final result isn't dry. The trio of cream cheese, provolone, and mozzarella creates a multi-dimensional cheese experience that is unmatched. Below are the core components you will need to gather.
Notes and Substitutions
If you prefer a more traditional texture, you can swap the ground beef for thinly sliced flank steak or ribeye. For the vegetables, while green bell peppers provide that classic bitter-sweet crunch, adding red or orange peppers can introduce a bit more natural sweetness.

For a dairy-free version, though difficult with this specific dish, you would need to use cashew-based cream cheese and vegan provolone alternatives. Always check your Worcestershire sauce labels, as some brands contain hidden sugars that might affect your keto status.
Equipment
To make this Keto Philly Cheesesteak Casserole, you will need a large skillet (cast iron works beautifully for browning the meat), a 9x13 inch baking dish, a sharp chef's knife for dicing vegetables, and a sturdy spatula. Having a colander or slotted spoon on hand to drain the beef fat is also essential to prevent a greasy final product.
Instructions
Follow these steps to create your masterpiece:
- Preheat your oven to 375°F (190°C) and grease a 9x13 inch baking dish with olive oil or cooking spray.
- In a large skillet over medium-high heat, add the olive oil. Once hot, add the diced onions and bell peppers. Sauté for 5-7 minutes until the vegetables are softened and slightly caramelized.
- Add the minced garlic to the skillet and cook for an additional minute until fragrant. Remove the vegetables from the pan and set them aside.
- In the same skillet, add the ground beef. Season with salt and pepper. Brown the meat thoroughly, breaking it up with a spatula as it cooks.
- Once the beef is fully cooked, drain any excess grease. This is a crucial step to ensure the Keto Philly Cheesesteak Casserole isn't too oily.
- Stir the sautéed vegetables back into the skillet with the beef. Add the Worcestershire sauce and the block of cream cheese. Stir constantly until the cream cheese is fully melted and forms a smooth, creamy sauce coating the meat and veggies.
- Transfer the mixture into the prepared baking dish, spreading it into an even layer.
- Layer the provolone cheese slices over the top, then sprinkle the shredded mozzarella evenly across the surface.
- Place the Keto Philly Cheesesteak Casserole in the oven and bake for 15-20 minutes, or until the cheese is melted and bubbling. For a golden crust, you can broil it for the last 2 minutes.
- Let the casserole rest for 5 minutes before serving to allow the sauce to set.
Pro Tips
For the absolute best results with your Keto Philly Cheesesteak Casserole, do not rush the vegetable sautéing process. Caramelizing the onions and peppers adds a depth of flavor that raw vegetables simply cannot provide. Furthermore, using a combination of cheeses is key. Provolone provides the iconic Philly flavor, while mozzarella offers the perfect cheese pull. If you want an even richer dish, you can add a splash of heavy cream to the meat mixture along with the cream cheese. Always ensure you are using high-quality beef from a trusted source, such as Food Network approved suppliers, to ensure the meat is lean but flavorful.
Serving, Storage & Variations
Serve your Keto Philly Cheesesteak Casserole with a side of roasted broccoli, a crisp green salad, or over a bed of cauliflower rice. To store, place leftovers in an airtight container in the refrigerator for up to 4 days. When reheating, use the oven at 350°F to maintain the texture of the cheese, though a microwave works for a quick lunch. For variations, consider adding sliced mushrooms during the sauté step for an 'earthier' version, or add a pinch of red pepper flakes if you enjoy a spicy kick. You can even top the finished dish with fresh parsley or chopped green onions for a pop of color and freshness.
