Savor the iconic flavors of a Philly cheesesteak in a hearty, baked casserole. This comforting dish features tender beef, sautéed vegetables, and a rich, cheesy topping.

Ingredients

For the casserole:

  • 1.5 lbs thinly sliced beef (ribeye or sirloin)

  • 1 onion, thinly sliced

  • 1 green bell pepper, thinly sliced

  • 8 oz mushrooms, sliced

  • 2 tbsp olive oil

  • 1 tsp salt

  • ½ tsp black pepper

  • 8 oz cream cheese, softened

  • ½ cup mayonnaise

  • 1 cup shredded provolone cheese (or your choice of cheese)

  • 1 cup shredded mozzarella cheese

  • ¼ cup grated Parmesan cheese

For the seasoning mix:

  • 1 tsp garlic powder

  • 1 tsp onion powder

  • 1 tsp dried oregano

  • 1 tsp dried basil

  • ½ tsp red pepper flakes (adjust to taste)

  • Salt and black pepper, to taste

Instructions

  1. Preheat the oven to 375°F (190°C).

  2. Cook the beef: Heat olive oil in a large skillet over medium-high heat. Add the sliced beef and cook until browned and no longer pink. Season with salt and pepper. Remove from the skillet and set aside.

  3. Sauté the vegetables: In the same skillet, cook the onions, bell peppers, and mushrooms until softened and lightly caramelized (about 5–7 minutes). Remove and set aside.

  4. Make the cheese mixture: In a bowl, blend together the cream cheese and mayonnaise until smooth. Stir in the Parmesan, and half of the provolone and mozzarella.

  5. Mix the seasoning: In a small bowl, combine the garlic powder, onion powder, oregano, basil, red pepper flakes, salt, and pepper.

  6. Assemble the casserole:

    • Grease a 9x13-inch baking dish.

    • Layer half of the cooked beef at the bottom of the dish.

    • Sprinkle with half of the seasoning mix.

    • Top with the sautéed vegetables.

    • Spread the cheese mixture evenly over the vegetables.

    • Add the remaining beef and top with the rest of the seasoning mix.

    • Sprinkle with the remaining provolone and mozzarella.

  7. Bake: Place the casserole in the oven and bake for 25–30 minutes, or until hot and bubbly with a golden-brown cheese topping.

  8. Cool and serve: Allow the casserole to rest for a few minutes before serving.
