Philly Cheesesteak Casserole is a hearty, cheesy dish that transforms the iconic sandwich into a baked dinner. With tender steak, sautéed peppers and onions, creamy cheese, and optional pasta or potatoes, it’s a comforting, crowd-pleasing meal.

Ingredients

  1. 1 lb thinly sliced steak (ribeye, sirloin, or shaved beef)
  2. 1 green bell pepper, sliced
  3. 1 red bell pepper, sliced
  4. 1 medium onion, sliced
  5. 2 cloves garlic, minced
  6. 4 oz cream cheese
  7. 1 cup shredded mozzarella cheese
  8. 6 slices provolone cheese (or 1 cup shredded)
  9. 2 tbsp olive oil or butter
  10. 1 tbsp Worcestershire sauce
  11. 1/2 tsp salt
  12. 1/4 tsp black pepper
  13. 1 tsp Italian seasoning (optional)
  14. 2 cups cooked pasta, potatoes, or cauliflower rice (optional base)

Instructions

Preheat oven to 375°F (190°C).

  1. In a large skillet, heat olive oil or butter over medium heat. Add sliced bell peppers and onion. Sauté for 5–7 minutes until soft. Add garlic and cook for 1 more minute. Remove and set aside.
  2. In the same skillet, cook steak slices until browned. Drain any excess fat.
  3. Season steak with Worcestershire sauce, salt, pepper, and optional Italian seasoning.
  4. Add cream cheese and stir until melted and combined with the steak.
  5. Return sautéed peppers and onions to the skillet. Stir to combine.
  6. If using a base (pasta, potatoes, or cauliflower rice), stir it in now.
  7. Transfer mixture to a greased 9×13-inch baking dish. Top with provolone and mozzarella cheese.
  8. Bake uncovered for 20–25 minutes, or until cheese is melted and bubbly. Broil for 2–3 minutes if desired for a golden top.
  9. Let rest for 5 minutes before serving.

Notes

  • Use ground beef or roast beef as a shortcut alternative to steak.
  • Make it low-carb by skipping the pasta and using just steak, veggies, and cheese.
  • Add sautéed mushrooms for extra flavor and texture.
  • Use cheese whiz or American cheese for a classic Philly twist.
  • Store leftovers in the fridge for up to 4 days or freeze up to 2 months.
