  • Total Time: 35 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 1 lb (450g) of thinly sliced sirloin or ribeye steak
  • 1 medium onion, sliced
  • 1 green bell pepper, sliced
  • 3 cloves garlic, minced
  • 1 cup of sliced mushrooms (optional for extra flavor)
  • 2 cups shredded mozzarella cheese
  • 1/2 cup cream cheese, softened
  • 1/4 cup sour cream (for creaminess)
  • 2 tbsp olive oil
  • Salt and pepper to taste
  • Fresh parsley for garnish (optional)

Instructions

  1. Start by thinly slicing the steak and chopping the vegetables. Keep everything ready for quick cooking.
  2. Heat olive oil in a large skillet over medium-high heat. Add the sliced steak and cook until browned, about 3-4 minutes per side. Remove and set aside. In the same skillet, sauté onions, bell peppers, garlic, and mushrooms until tender, about 5-7 minutes.
  3. In a bowl, combine softened cream cheese, sour cream, and a pinch of salt and pepper. Mix until smooth. Stir in half of the shredded mozzarella cheese.
  4. In a baking dish, layer the cooked steak and sautéed vegetables. Spread the creamy cheese mixture evenly over the top. Sprinkle with remaining mozzarella cheese.
  5. Preheat your oven to 375°F (190°C). Bake the casserole for 20-25 minutes or until the cheese is melted and golden brown. Garnish with chopped parsley if desired.

Notes

  • Use thinly sliced steak for quick cooking and authentic texture.
  • Feel free to add extra veggies like zucchini or spinach for more nutrients.
  • Choose a high-quality shredded cheese for a richer flavor.
  • Use a glass or ceramic baking dish for even heat distribution.
