How to Make Low Carb Philly Cheesesteak Casserole
-
Preheat the oven to 350°F (175°C) and prepare a 9×13 baking dish with non-stick spray. This helps the casserole come out easily and prevents sticking.
-
Sauté the diced onions and bell peppers in a large skillet with olive oil over medium heat. Cook for 5-6 minutes until they’re softened and fragrant, filling your kitchen with a delightful aroma.
-
Add minced garlic to the skillet and cook for another 30 seconds, stirring constantly until the garlic is aromatic but not burnt. This adds an incredible depth to your casserole.
-
Incorporate the ground beef into the skillet, seasoning it with salt and pepper. Cook until browned and crumbly, about 7-8 minutes, draining any excess fat if necessary to keep it light.
-
Mix in Worcestershire sauce and softened cream cheese, stirring until creamy and well combined. The cream cheese will melt and blend smoothly with the beef mixture, adding wonderful richness.
-
Transfer the mixture into the prepared baking dish. Top it off with torn provolone slices followed by a generous layer of shredded mozzarella cheese for that stretchy, gooey goodness.
-
Bake in the preheated oven for 22-25 minutes, or until the cheese is melted and bubbly with a light golden color. Let the casserole rest for about 5 minutes before serving to set.
Optional: Serve with a sprinkle of fresh parsley for color and added flavor.
