Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C) and greasing a 9×13 inch baking dish with non-stick spray. This will ensure your casserole comes out easily and prevents sticking. Prepare everything else while the oven heats up—you’ll want to have everything ready when it’s time to bake your Low Carb Philly Cheesesteak Casserole!

Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once hot, add 1 large diced onion and 2 diced bell peppers. Sauté these colorful veggies for around 5-6 minutes until they soften and become fragrant. Then, add 2 minced garlic cloves and cook for another 30 seconds, stirring frequently to prevent burning.

Step 3: Cook the Ground Beef
Add 2 pounds of ground beef to the skillet, breaking it apart as you cook. Season generously with salt and pepper, then cook for about 7-8 minutes until the beef is browned and no longer pink. If there’s excess fat, carefully drain it from the skillet to keep your Low Carb Philly Cheesesteak Casserole from becoming greasy.

Step 4: Mix in the Sauce and Cream Cheese
Stir in 2 tablespoons of Worcestershire sauce, allowing the savory flavors to meld. Next, add 8 ounces of softened cream cheese to the mix. Stir continuously until the cream cheese melts and blends into a creamy, delightful mixture that will add richness to your casserole.

Step 5: Transfer the Mixture
Carefully transfer the beef and vegetable mixture to your prepared baking dish, spreading it evenly across the bottom. This will serve as the hearty foundation of your Low Carb Philly Cheesesteak Casserole, ensuring every bite is filled with flavor and texture.

Step 6: Add the Cheese Layers
Begin layering the toppings by placing 8 ounces of provolone cheese on top of the beef mixture, then sprinkle 1.5 cups of shredded mozzarella cheese evenly over that. This melty cheese blend will create a gooey and delicious topping for your casserole, enhancing the classic cheesesteak experience.

Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for 22-25 minutes. Keep an eye on the casserole as it bakes, watching for the cheese to become melted, bubbly, and lightly golden on top. This is your cue that the Low Carb Philly Cheesesteak Casserole is ready to come out!

Step 8: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This resting time allows the layers to settle, making it easier to serve. Cut into squares and enjoy your hearty, satisfying Low Carb Philly Cheesesteak Casserole with family and friends!
