Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray to prevent sticking. This will ensure your Low Carb Philly Cheesesteak Casserole comes out easily after baking and is ready for serving. Set the prepared dish aside while you start cooking the filling.
Step 2: Sauté the Vegetables
In a large skillet over medium heat, pour in a splash of olive oil. Add the diced onions and bell peppers, sautéing for 5-6 minutes until they are softened and fragrant. When the vegetables have a nice golden color, stir in the minced garlic and cook for an additional 30 seconds to release its aromatic flavors.
Step 3: Brown the Ground Beef
Add the ground beef to the skillet, breaking it up with a spatula as it cooks. Season the meat with salt and pepper and continue to cook for 7-8 minutes until the beef is browned and no longer pink. If there’s excess fat in the skillet, carefully drain it to maintain a perfect consistency for your casserole.
Step 4: Mix in Cream Cheese and Flavor
Stir in the Worcestershire sauce to enhance the flavor of your beef mixture. Then, reduce the heat and add the softened cream cheese, mixing well until it melts into a creamy and cohesive mixture. This will create a delightful, savory filling for your Low Carb Philly Cheesesteak Casserole.
Step 5: Assemble the Casserole
Transfer the seasoned beef and vegetable mixture into your prepared baking dish, spreading it evenly. Layer the mixture with torn pieces of provolone cheese, allowing the cheesy goodness to meld perfectly with the filling. Finish by generously topping it with mozzarella cheese for that irresistible stretchiness.
Step 6: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 22-25 minutes. Keep an eye on it; you want the cheese to be bubbly and lightly golden, creating an enticing top layer. Once done, remove from the oven and let the Low Carb Philly Cheesesteak Casserole rest for about 5 minutes to set before serving.

Make Ahead Options
These Low Carb Philly Cheesesteak Casserole are perfect for busy weeknights and meal prep enthusiasts! You can sauté the onions, peppers, and ground beef up to 24 hours in advance, allowing the flavors to meld together beautifully. Simply refrigerate the mixture in an airtight container once it cools. On the day you plan to serve, layer the mixture with cheese and bake as instructed for a deliciously hearty dish that’s just as satisfying. If you want even more convenience, assemble the entire casserole and cover tightly. It can be stored in the fridge for up to 3 days—just remember to let it sit at room temperature for 30 minutes before baking to ensure even cooking. Enjoy a comforting meal with minimal effort!
