How to Make Low Carb Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick spray to ensure your casserole won’t stick.
Step 2: Sauté Vegetables
Heat the olive oil in a large skillet over medium heat.
* Add the diced onions and bell peppers. Cook for about 5-6 minutes until they begin to soften.
* Add the minced garlic and cook for another 30 seconds until fragrant.
Step 3: Brown the Beef
Add the ground beef to the skillet with the vegetables.
* Season with salt and pepper to taste.
* Cook while breaking up the meat with a spatula until completely browned, about 7-8 minutes.
Step 4: Add Worcestershire Sauce
Stir in the Worcestershire sauce. Allow it to coat the meat mixture and enhance the flavors throughout.
Step 5: Incorporate Cream Cheese
Reduce heat to low.
* Add the softened cream cheese to the skillet.
* Stir until it melts completely, coating the meat and vegetable mixture evenly.
Step 6: Transfer Mixture
Once fully combined, transfer the mixture to the prepared baking dish. Spread it evenly across the bottom.
Step 7: Layer Cheeses
Layer the sliced provolone cheese over the beef mixture.
Then sprinkle shredded mozzarella cheese evenly on top.
Step 8: Bake Casserole
Place in the preheated oven.
* Bake for 20-25 minutes until the cheese is melted, bubbly, and slightly golden on top.
Step 9: Rest Before Serving
Allow the casserole to rest for 5 minutes before serving. This helps meld flavors together and makes serving easier.

Common Mistakes to Avoid
