Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. This initial step ensures your Low Carb Philly Cheesesteak Casserole is ready for assembly and baking without sticking, setting the stage for a perfect meal.

Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 1 large yellow onion and 1 large green bell pepper, both thinly sliced. Sauté for 5-7 minutes until softened. Stir in 2 cloves minced garlic for the last minute until fragrant.

Remove the cooked vegetables from the skillet and set them aside. Add the 1 1/2 lbs thinly sliced beef (ribeye or sirloin) to the hot skillet. Cook, breaking it up with a spoon, until it is fully browned. Drain any excess fat from the skillet.

Return the cooked vegetables to the skillet with the beef. Stir in 1 tbsp Worcestershire sauce, 1/4 cup beef broth, 1/2 tsp black pepper, and salt to taste. Add a pinch of red pepper flakes if desired. This forms the rich, savory base of your Low Carb Philly Cheesesteak Casserole.

In a medium bowl, whisk together 8 oz softened cream cheese and 1/2 cup heavy cream until the mixture is smooth and creamy. This rich sauce will bind the casserole together, adding a decadent texture to your Low Carb Philly Cheesesteak Casserole.

Spread the beef and vegetable mixture evenly into the prepared baking dish. Dollop the cream cheese mixture over the top, then gently spread it out to cover. Layer with 8 oz sliced provolone cheese and sprinkle with 4 oz shredded mozzarella cheese.

Bake for 20-25 minutes, or until the cheese is bubbly, melted, and lightly golden brown on top. Let the casserole rest for 5 minutes before serving. This allows the flavors to meld and the casserole to set perfectly for easy scooping.
