– 1 tbsp olive oil
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 the 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 Flavor Enhancers
Stir in the Worcestershire sauce:
* Allow it to coat the meat mixture and enhance the flavors.
Step 5: Create Creamy Texture
Reduce heat to low. Add the softened cream cheese to the skillet:
* Stir until it melts completely and coats the meat and vegetable mixture evenly, creating a creamy texture.
Step 6: Transfer Mixture to Baking Dish
Once fully combined:
* Transfer the mixture to the prepared baking dish, spreading it evenly.
Step 7: Layer Cheeses
Layer the sliced provolone cheese over the beef mixture:
* Then sprinkle the shredded mozzarella cheese evenly on top.
Step 8: Bake Until Golden
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 casserole to rest for about 5 minutes before serving:
* This helps flavors meld together and makes serving easier.
