Preparation Method

This Low Carb Philly Cheesesteak Casserole follows a clear, logical cooking process that builds flavor at each stage. The steps below are designed to help you achieve the best texture, taste, and presentation.

Step 1: Preheat the Oven and Prepare the Baking Dish

Begin by preheating your oven to 350°F (175°C). This ensures the oven reaches the correct temperature by the time the casserole is ready to bake.

Lightly spray a 9×13 baking dish with non-stick spray. This step prevents sticking and makes serving and cleanup easier. Set the prepared dish aside.

Step 2: Heat the Olive Oil

Place a large skillet over medium heat. Add 1 tablespoon of olive oil and allow it to heat until it shimmers slightly. The olive oil helps prevent sticking and adds a subtle richness to the vegetables.

Step 3: Cook the Onions and Bell Peppers

Add the diced onion and bell peppers to the hot oil. Cook them for 5 to 6 minutes, stirring occasionally. As they cook, they will soften and release their natural sweetness, which is essential to the authentic Philly cheesesteak flavor.

The vegetables should become tender and fragrant but not overly browned.

Step 4: Add the Garlic

Add the minced garlic to the skillet and cook for about 30 seconds, stirring constantly. Garlic cooks quickly, so this step should be brief to prevent burning. The goal is to release its aroma and enhance the savory base of the dish.

Step 5: Brown the Ground Beef

Add the 2 lbs of ground beef to the skillet. Use a spatula to break it into small pieces as it cooks. Season generously with salt and pepper.

Cook the beef for 7 to 8 minutes, or until it is fully browned with no pink remaining. Proper browning develops flavor and ensures the casserole has a hearty texture.

If there is excess fat, carefully drain it from the skillet. Removing excess grease helps the final casserole set properly and prevents it from becoming overly oily.

Step 6: Add Worcestershire Sauce

Stir in the 2 tablespoons of Worcestershire sauce, ensuring it coats the beef and vegetables evenly. This ingredient adds depth, tanginess, and umami, enhancing the overall flavor profile of the casserole.

Reduce the heat to low after mixing.

Step 7: Incorporate the Cream Cheese

Add the softened cream cheese to the skillet. Stir continuously until it is fully melted and combined with the beef mixture. This step transforms the filling into a rich, creamy base that holds the casserole together.

Ensure the cream cheese is evenly distributed for consistent texture in every bite.

Step 8: Transfer to the Baking Dish

Once the mixture is smooth and well combined, transfer it to the prepared 9×13 baking dish. Spread it evenly using a spatula to ensure uniform baking.

Step 9: Add the Cheese Layers

Layer the provolone cheese slices over the beef mixture, tearing them into pieces if necessary to cover the surface evenly. Provolone provides a classic Philly cheesesteak flavor and melts smoothly.

Next, sprinkle the shredded mozzarella cheese evenly over the provolone layer. Mozzarella adds stretchiness and a beautiful golden finish.

Step 10: Bake the Casserole

Place the baking dish in the preheated oven and bake for 22 to 25 minutes. The cheese should be fully melted, bubbly, and lightly golden on top.

Avoid overbaking, as this can cause the cheese to become tough.

Step 11: Rest Before Serving

Remove the casserole from the oven and let it rest for 5 minutes before serving. This resting time allows the flavors to meld and the casserole to firm up slightly, making it easier to serve.

Notes

• Choosing 80/20 ground beef ensures juicy, flavorful results.
• Draining excess fat before baking helps maintain a firm consistency.
• Provolone can be substituted with cheddar for a different flavor profile, though provolone provides the most authentic cheesesteak taste.
• Cream cheese should be fully softened before adding to ensure smooth blending.
