How to Make Low Carb Philly Cheesesteak Casserole

  1. Preheat your oven to 350°F (175°C). Prepare a 9×13 baking dish by spraying it with non-stick spray to keep everything from sticking together.
  2. Sauté the diced onions and bell peppers in a large skillet with olive oil over medium heat for about 5-6 minutes. Cook until they’re softened and fragrant, creating a flavorful base.
  3. Add minced garlic to the skillet and stir constantly for 30 seconds. This will elevate the dish with its aromatic goodness.
  4. Cook the ground beef in the skillet by breaking it up and seasoning with salt and pepper. Cook until browned and fully cooked, roughly 7-8 minutes. Drain any excess fat if necessary to keep it from being greasy.
  5. Mix in Worcestershire sauce, then reduce the heat. Add the softened cream cheese, stirring until it’s melted and creamy. This will beautifully bind the mixture together.
  6. Spread the beef mixture evenly into the prepared baking dish. Layer the sliced provolone cheese over the top, followed by the shredded mozzarella for that glorious cheesy finish.
  7. Bake for 22-25 minutes until the cheese is melted, bubbly, and lightly golden. Let it cool for 5 minutes before diving in with your family!

Very! Feel free to incorporate sautéed mushrooms or fresh jalapeños for added nutrition and flavor.
