Keto Philly Cheesesteak Casserole

This flavorful, high-protein casserole captures all the classic tastes of a Philly cheesesteak while remaining mindful of your nutritional goals. It is a practical and satisfying meal that fits perfectly into a structured plan, especially for those focusing on low-carb or point-based systems.

Ingredients

  • 1 ½ lbs Ground beef (or thinly sliced steak)

  • 1 tbsp Olive oil or butter

  • 3 Bell peppers (1 green, 1 red, and 1 yellow), sliced

  • 1 Small onion, sliced

  • 1 cup Mushrooms, sliced

  • 2 Cloves garlic, minced

  • 4 oz Cream cheese, softened

  • ½ cup Beef broth

  • 1 tbsp Worcestershire sauce

  • 1 tsp Italian seasoning

  • To taste: Salt and pepper

  • 1 ½ cups Shredded provolone or mozzarella cheese

  • ½ cup Shredded cheddar cheese (optional)

Step-by-Step Instructions

  1. Prepare the Oven: Preheat your oven to 190°C and lightly grease a 9×13-inch baking dish.

  2. Brown the Protein: Heat the olive oil or butter in a large skillet over medium heat. Add the beef and cook until it is thoroughly browned. Season with salt and pepper, then drain any excess grease from the pan.

  3. Sauté the Vegetables: Add the sliced onions, peppers, mushrooms, and minced garlic to the skillet with the beef. Cook for 4–5 minutes until the vegetables have slightly softened but still retain some texture.

  4. Create the Creamy Base: Stir in the softened cream cheese, beef broth, Worcestershire sauce, and Italian seasoning. Continue to mix over the heat until the cream cheese is completely melted and the ingredients are well combined into a smooth sauce.

  5. Assemble the Casserole: Transfer the beef and vegetable mixture into your prepared baking dish. Spread it out evenly and sprinkle the shredded provolone (and cheddar, if using) across the top.

  6. Bake to Perfection: Place the dish in the oven and bake for 15–20 minutes. The casserole is ready when the cheese is melted, bubbly, and slightly golden.

  7. Rest and Serve: Allow the casserole to cool for about 5 minutes before serving. This helps the sauce set slightly for better portioning.

Cooking Tip

If you are using thinly sliced steak instead of ground beef, sear the steak quickly over high heat first to lock in the juices before adding the vegetables. This keeps the meat tender during the baking process.
